Cisco 350-601 Implementing Cisco Data Center Core Technologies (DCCOR) Exam Practice Test

 The preserve identities feature is not included in the logical configuration backup operation type. This type of backup includes the configuration settings that are logically grouped, such as service profiles, policies, and pools, but does not include the unique identifiers or configurations that are specific to a particular system or setup, which are preserved in a full state or system configuration backup.

References := For detailed information on the different backup operation types and their characteristics, please refer to the official Cisco documentation on Implementing and Operating Cisco Data Center Core Technologies (DCCOR), specifically the sections related to backup and restore operations within the Cisco Unified Computing System (UCS) Manager1.

PowerShell is a task automation and configuration management framework from Microsoft, consisting of a command-line shell and the associated scripting language. It is integrated with Cisco UCS Manager and provides cmdlets for automating the management of Cisco UCS domains, including Service Profiles. The UCS PowerTool is a set of PowerShell modules designed specifically for Cisco UCS, making it a suitable choice for a network engineer with scripting skills but limited programming knowledge. It supports configuration tasks for both B-Series Blade Servers and C-Series Rack Servers, aligning with the administrator’s future needs.

 Changing the default host firmware policy in Cisco UCS Manager affects any service profile that uses the global-default host firmware policy. This is because the global-default host firmware policy serves as a template for service profiles that do not have a specific host firmware policy defined. When changes are made to the default policy, they propagate to all service profiles that reference it, potentially affecting the firmware version and settings across multiple servers.

 To provision a new uplink and increase the available bandwidth for the NPV enabled switch, the commands in Option A should be used. These commands will configure the additional uplink to the NPIV switch, thus addressing the bandwidth contention issues experienced by the servers.

To configure HSRP on a Nexus 7000 series switch for VLAN 100 and ensure the router is the active master, you would typically use the hsrp command within the VLAN configuration mode, set the priority higher than the default to make it the preferred active router, and use the preempt command to allow the router to take over as the active router if it has a higher priority.

 The HA NOT READY status on a Cisco Fabric Interconnect typically indicates that the system is not in a state to provide High Availability due to certain connectivity issues. In this case, the status message “No device connected to this Fabric Interconnect” suggests that there is no connectivity through the management ports. Establishing a connection through these ports is essential for the Fabric Interconnect to communicate with other devices in the network and form a High Availability cluster. Once the management ports are connected and properly configured, the HA NOT READY status should be resolved.

References := This explanation is based on standard procedures for addressing High Availability issues in Cisco Data Center environments, as outlined in Cisco’s technical documentation and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course materials

 When a VLAN is added to a trunk and it does not appear on the vNIC of an associated server, it typically indicates that the vNIC template is not updating as it should to reflect changes. By changing the template type of Trunk-A to an updating template, any changes made to the trunk configuration, such as adding a new VLAN, will be dynamically applied to all vNICs associated with that template. This action will allow the newly added VLAN to be included in the vNIC configuration without the need to manually update each vNIC or recreate the templates.

References := This recommendation aligns with best practices for managing vNIC templates in Cisco UCS environments, where updating templates are used to ensure changes propagate automatically to all associated instances

 EPLD upgrades on Cisco MDS 9000 series switches can be done without powering down the module during the upgrade (Option B), which allows for continuous operation and no downtime. Additionally, EPLDs can be upgraded without replacing the hardware (Option D), making the process more cost-effective and less resource-intensive. References := Cisco Data Center Core Technologies

You can use firmware packages in service profiles to upgrade the server and adapter firmware, including the BIOS on the server, by defining a host firmware policy and including it in the service profile associated with a server.

Ansible is an open-source IT automation tool that is easy to set up and does not require an agent to be installed on target devices. It uses a declarative language and can be extended with custom modules written in Python, which aligns well with the IT team’s experience. Ansible’s agentless architecture and support for Python make it an ideal choice for the company’s requirements.

 Option C is the correct configuration to apply a power redundancy policy on a Cisco UCS C-Series Rack Server that supports two power sources. The power redundancy policy determines how the server uses the available power supplies to optimize power usage. The grid option means that the server uses power from both power supplies simultaneously. If one power supply fails, the server continues to operate with the remaining power supply. The other options are not suitable for this requirement. The n+1 option means that the server uses one fewer power supply than the number of power supplies that are installed. If a power supply fails, the server uses the extra power supply. The non-redundant option means that the server uses only one power supply, regardless of the number of power supplies that are installed. If the power supply fails, the server shuts down. The ps-redundant option means that the server uses power from the most efficient power supply. If the power supply fails, the server switches to another power supply. References:

Option A is the correct command set to configure an extra keyring in Cisco UCS Manager. The commands create a keyring named “extra” with a modulus of 4096 bits, which provides a high level of encryption. The commands also generate a self-signed certificate for the keyring, which enables secure authentication when users use the web interface. References:

 In a VXLAN data center fabric, inter-VNI communication requires mapping Layer 2 (L2) VLANs to their respective L2 VNIs and associating them with the correct Layer 3 (L3) VNI that corresponds to the VRF. In this case, VLAN 100 is mapped to L2 VNI 2020, and for inter-VNI routing to occur, it must be associated with an L3 VNI that corresponds to the VRF, which is Test_Telco_VRF to L3 VNI 1010. References: For more detailed information, you can refer to the Cisco Programmable Fabric with VXLAN BGP EVPN Configuration Guide1 and the Data Center VXLAN EVPN guide

When downloading a firmware image to a Cisco UCS Fabric Interconnect, especially from a remote location, it is crucial to use a protocol that provides both encryption and authentication to ensure the security and integrity of the file transfer. HTTPS (Hypertext Transfer Protocol Secure) is the protocol that meets these requirements. It is widely used for secure communication over a computer network within a web browser, with encryption provided by Transport Layer Security (TLS), which ensures that the transfer of the firmware image is secure and authenticated1.

References:

• Cisco UCS Manager Firmware Management Guide, which provides detailed instructions on managing firmware through UCS Manager, including downloading firmware images to the Fabric Interconnect

Option C is the correct configuration that is expected to be saved by using a logical configuration backup. A logical configuration backup includes the service profiles, service profile templates, policies, pools, and logical LAN and SAN connectivity configuration. It does not include the systems, roles, or servers configuration, which are part of the full state or all configuration backups. References:

• Cisco UCS Manager GUI Configuration Guide, Release 4.0 - Backing Up and Restoring the System Configuration [Cisco UCS Manager], Backing Up and Restoring the System Configuration, Backup Types

To recover the configuration of the Cisco UCS Manager from a full backup available on a backup SCP server, the actions in Option A should be followed. These actions typically involve accessing the Cisco UCS Manager interface, navigating to the backup and restore settings, and initiating a restore operation using the SCP protocol to retrieve the backup file from the SCP server.

References: = For detailed steps and best practices, you can refer to the official Cisco documentation on “Backing Up and Restoring the Configuration” in the Cisco UCS Manager guide1.

NX-API Sandbox is a utility that allows the engineer to translate traditional Nexus CLI inputs and generate Python code using XML and JSON message formats. It is available on a Nexus 7700 series switch as a web-based tool that can be accessed from a browser. It provides a graphical interface for entering CLI commands and viewing the corresponding Python code and output. It also allows the engineer to execute the Python code directly on the switch or copy it to a script file. References := [Cisco Nexus 7000 Series NX-OS Programmability Guide]

In a vPC configuration, both Nexus switches (N7K-1 and N7K-2) are designed to work together to present themselves as a single logical entity to downstream devices. This design allows for a loop-free topology without the need for Spanning Tree Protocol (STP) to block any of the ports to prevent loops. As a result, both N7K-1 and N7K-2 share the same STP priority, making them appear as a single STP root to the rest of the network. This approach enhances the use of available bandwidth and provides redundancy without relying on STP to resolve loops.

References := The principles of vPC and its interaction with STP are well documented in Cisco’s technical literature, including the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course materials1. For a more detailed explanation, please refer to these resources.

 A full state backup of a Cisco UCS Manager database performs a complete binary dump of the database as a .bin file, not a .txz or a .sql file. A full state backup contains all of the configurations and all of the runtime states and statuses of the Cisco UCS domain, but not the passwords. A full state backup can be used to restore the Cisco UCS Manager database to the same or a different fabric interconnect, as long as the hardware configuration is identical. References := Implementing and Operating Cisco Data Center Core Technologies (DCCOR) - Cisco, Chapter 5: Implementing Cisco Unified Computing System Rack Servers, Section: Back Up and Restore the Cisco UCS Manager Database

On Nexus switches, the equivalent command to save the configuration to NVRAM is ‘copy running-config startup-config’. The ‘write memory’ command is specific to Catalyst switches and is not used on Nexus switches.

To create a VSAN on the network, the engineer needs to select Fabric A from the drop-down menu. This will allow the engineer to assign a VSAN ID and a name to the new VSAN, and to add members to the VSAN. The other options are not relevant for creating a VSAN. Fabric B is the other fabric interconnect, FC Zoning Enabled is a feature that allows traffic isolation within a VSAN, and Common/Global is a default VSAN that cannot be modified. References:

• Cisco UCS Manager GUI Configuration Guide, Release 4.0 - Configuring SAN Connectivity [Cisco UCS Manager], Configuring SAN Connectivity, Creating a VSAN
• Cisco UCS Manager GUI Configuration Guide, Release 4.0 - Configuring SAN Connectivity [Cisco UCS Manager], Configuring SAN Connectivity, Configuring FC Zoning
• Cisco UCS Manager GUI Configuration Guide, Release 4.0 - Configuring SAN Connectivity [Cisco UCS Manager], Configuring SAN Connectivity, Default VSANs

After creating a CA-signed keyring for HTTPS access in Cisco UCS Manager, the next step is to create a trusted point. This action associates the keyring with a certificate and designates the certification authority (CA) that will be recognized as valid for the system

When configuring a vHBA template in Cisco UCS Manager, the engineer needs to specify the logical addresses used by the vHBA and the path through which the SAN traffic flows. The two resources that must be specified in the vHBA template are the WWN (World Wide Name) and the Fabric ID. The WWN is a unique identifier for the vHBA that is used for zoning and LUN masking in the SAN environment. The WWN can be assigned manually or automatically from a WWN pool. The Fabric ID is a parameter that determines which fabric interconnect (A or B) the vHBA is associated with. The Fabric ID can be set to a specific value or to ‘default’, which allows the system to choose the best available fabric interconnect based on the availability and load balancing policies. References :=

The configuration in option C, which includes commands such as switchport port-security, switchport port-security violation restrict, and switchport port-security mac-address sticky, meets the security requirements specified. This configuration secures the end-user ports by limiting the number of MAC addresses allowed on the port, logs security breaches without shutting down the port (restrict mode), and retains the MAC address configuration even if the device restarts (sticky option).

The ACI REST API is a programmatic interface that uses REST architecture to interact with the management information tree (MIT) of the Cisco Application Policy Infrastructure Controller (APIC). The API requires authentication for users to access and manipulate the objects in the MIT. The authentication is based on username and password credentials, and the API provides several methods to manage the session authentication. Two of these methods are:

• POST to aaaLogin. This method logs in a user and opens a session. The message body contains an aaa:User object with the name and password attributes, and the response contains a session token and cookie. The session token and cookie are required for subsequent requests to the API, and they have a limited validity period that can be refreshed.
• DELETE to aaaLogout. This method logs out a user and closes a session. The message body contains an aaa:User object with the name attribute, and the response contains a status code indicating the success or failure of the operation. The session token and cookie are invalidated and cannot be used for further requests to the API.

References := The information is based on the Cisco APIC REST API Configuration Guide, which explains the usage and features of the ACI REST API, including the authentication methods89.

 This configuration ensures that if AAA servers cannot be reached, the switch will fall back to using the local user database for authentication when accessing the console. The fallback error local keyword specifies that the local database should be used in case of an error in reaching the AAA servers1.

References := For more information on configuring AAA on Cisco MDS switches, you can refer to Cisco’s official documentation and community discussions which provide insights into setting up authentication methods for different access scenarios1. These resources explain how to configure the switch to handle authentication locally when remote AAA servers are not available.

 A logical backup includes all logical configuration settings such as service profiles, VLANs, VSANs, pools, and policies1. Since the end users are only allowed to make changes to the Service Profile configuration, a logical backup is appropriate as it will capture the state of these configurations without including system settings. Scheduling the logical backup at the start of the weekend ensures that the latest configurations are saved before any changes occur. Scheduling the import of this backup on Monday morning will restore the configurations to their state at the time of the backup, thus reverting any changes made by the end users during the weekend1.

References := The Cisco UCS Manager documentation provides detailed instructions on how to schedule backups and imports, which can be found in the official Cisco resources1. These documents outline the steps for setting up scheduled backups and imports, ensuring that the UCS Manager configuration can be restored to a specific state as required.

The series of commands provided in the exhibit are part of the process to update and activate firmware on a Cisco UCS server adapter. The update firmware command is used to update the firmware, while the activate firmware command, combined with the set-startup-only option, schedules the activation of the firmware upon the next reboot of the adapter. This means that the new firmware will not be active immediately but will take effect after the adapter is rebooted, ensuring that the current operations are not disrupted.

References: For further details on firmware management commands and their effects in Cisco Data Center Core Technologies, you can refer to the Cisco UCS Manager Firmware Management Guide, which provides comprehensive instructions on updating and activating firmware on UCS components1. Additionally, the Cisco UCS Manager CLI Configuration Guide offers insights into the CLI commands used for managing firmware

POAP is an automatic provisioning and zero-touch deployment feature that assists device owners in the

initial deployment and configuration of Nexus switches.

The feature works by checking for a local configuration script. If the script has been deleted, the switch has

been reset to factory settings, or this is the first boot-up, the POAP daemon will connect to a preset list of

servers to download an initial configuration file.

To perform this operation, the switch must first obtain an IP address from a local DHCP server. POAP

configuration settings can also be passed through the DHCP response.

Which conditions should be verified, so they need to be TRUE. Like no startup (A) and bootup (B). C means

that it needs to miss a license file and E means it needs to miss an NX-OS image.

 The vHBA policy in Cisco UCS Manager is used to specify the WWPN of the storage array and can be configured for zoning type as single initiator multiple targets. The Fibre Channel adapter policy is used to configure interrupt handling and queues of the vHBA interface, which are essential for SAN connectivity.

Platform as a Service (PaaS) provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. Public cloud services are offered over the internet and are available to anyone who wants to purchase or use them. They are ideal for an engineer with a small budget and limited technical knowledge because they provide a cost-effective, scalable infrastructure that can grow with customer demand2.

References := For further details on cloud deployment models, including PaaS and public cloud, you can explore resources such as cloud deployment model comparisons and examples provided by various cloud service providers

 NFS, or Network File System, is a protocol that allows a user on a client computer to access files over a network in a manner similar to how local storage is accessed. NFS uses remote procedure calls (RPC) over TCP/IP for transport4. References := Wikipedia article on Network File System (NFS)4.

The src-dst-port load balancing method ensures that frames in the same flow (identified by the source and destination ports) follow the same links in a port channel. This method is effective in environments with Cisco MDS 9000 Series Switches because it maintains the order of frame delivery within a flow, which is crucial for storage traffic. Subsequent flows can use different links, allowing for efficient utilization of the port channel bandwidth. References: Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course materials.

 Terraform is an infrastructure as code (IaC) tool that allows users to define both cloud and on-premises resources in human-readable configuration files that can be versioned, reused, and shared. In the context of Cisco Data Center Core Technologies, Terraform can be used to enforce the desired state of the network by automatically managing, updating, and reverting configurations as needed to maintain consistency. It supports a wide range of Cisco products and can be extended to manage server infrastructure in the future.

References: The Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course provides insights into the essentials of automation and security in data centers, including the use of IaC tools like Terraform for enforcing desired state configuration1. Additionally, the Implementing Automation for Cisco Data Center Solutions (DCAUI) course further explores the implementation of automation solutions, including Terraform, in Cisco data centers2

 The QoS policy that controls only vHBA traffic is the Fibre Channel policy. In Cisco UCS, the Fibre Channel policy is specifically designed to manage the quality of service for traffic related to virtual Host Bus Adapters (vHBAs), which are used for Fibre Channel over Ethernet (FCoE) storage networking. This policy ensures that the storage traffic is appropriately prioritized and managed within the system.

• Cisco Data Center Core Technologies (DCCOR) study materials, which cover the concepts of QoS and vHBA configuration in a Cisco data center environment.

When using VMware vMotion to migrate a Cisco WSA virtual appliance from one physical host to another, it is essential that both physical hosts have access to the same network configurations. This includes the same defined networks to which the interfaces on the virtual appliance are mapped. This requirement ensures that the virtual appliance retains its network connectivity and continues to function correctly after the migration1.

References := For more information on the requirements and process of migrating a Cisco WSA virtual appliance using VMware vMotion, you can refer to the Cisco Secure Email and Web Virtual Appliance Installation Guide1.

• Create a user defined role and add the required privileges.
• Assign a role to a user. Comprehensive and Detailed Explanation: = To meet the requirements of adding a new FCoE VLAN to the core switches with restricted read-write access, the network engineer must create a user defined role and assign it to a user. A user defined role is a custom role that can be created to grant specific privileges and permissions to a user, based on the tasks and functions they need to perform. A user defined role can be created using the role command, and then the required privileges can be added using the rule command. For example, to create a role named FCoE-admin and add the privilege to configure FCoE VLANs, the following commands can be used:

role FCoE-admin rule 1 permit read-write feature fcoe rule 2 permit read-write feature vlan

After creating the user defined role, it can be assigned to a user using the username command. For example, to assign the FCoE-admin role to a user named John, the following command can be used:

username John role FCoE-admin

By creating and assigning a user defined role, the network engineer can ensure that the user has the minimum required privileges to perform the FCoE VLAN configuration, without granting them full network-admin access or modifying the existing roles. References :=

• Implementing and Operating Cisco Data Center Core Technologies (DCCOR) v1.2, Module 3: Data Center LAN Network Connectivity, Lesson 3.5: Cisco Nexus 7000 Series Switches
• Cisco Nexus 7000 Series NX-OS Security Configuration Guide, Release 6.x, Chapter: Configuring User Accounts and RBAC, Section: Configuring User-Defined Roles

To meet the specified requirements, a custom role needs to be created for User1 that grants full access to both the Fabric Interconnect infrastructure and network security operations, as well as storage operations configuration. This custom role ensures that User1 has the necessary permissions across different areas of the UCS Manager. Using LDAP for role-mapping with Active Directory allows for the integration of UCS Manager with the existing AD infrastructure, enabling centralized management of user credentials and access rights12.

References := The process for integrating Cisco UCS Manager with Active Directory and configuring custom roles can be found in the official Cisco documentation, such as the Cisco Secure Access Control System Configuration Guides and the Cisco Community discussions on UCS Manager and Active Directory integration12. These resources provide step-by-step instructions and best practices for setting up access control in UCS Manager using Active Directory.

The correct command to add to the script is option B, which concatenates the string ‘fusion-config_’ with the variable date to form the filename. This will result in a filename that includes the desired prefix followed by the current date, matching the format specified in the question.

References := For more information on scripting and automation within Cisco environments, you can refer to the Cisco Data Center Core Technologies documentation, which includes guidelines on using Python scripts for network configuration and management tasks.

The correct configuration for capturing both ingress and egress traffic between a Cisco MDS 9000 Series Switch and a storage array, specifically for VSAN 10, is found in Option D. This configuration involves setting up a SPAN session on the switch. The SPAN session is configured to monitor the source interface connected to the storage array (fc2/1) and send the captured traffic to the destination interface connected to the traffic analyzer (fc4/2). The source filter vsan 10 command ensures that only traffic from VSAN 10 is included in the capture, which aligns with the requirements specified.

References: For more detailed information on configuring SPAN sessions on Cisco MDS 9000 Series Switches, please refer to the Cisco MDS SAN-OS documentation, which provides guidelines on traffic monitoring and analysis in a Cisco data center network environment. Additionally, the Cisco Data Center Core Technologies (DCCOR) study materials offer insights into best practices for implementing traffic analysis solutions in a data center context.

 Creating a virtual iSCSI vNIC (B) is necessary for the server to perform an iSCSI boot from the storage array. This virtual iSCSI vNIC serves as an iSCSI boot firmware table (iBFT) configuration placeholder for iSCSI boot configuration. It is not an actual vNIC but is essential for the iSCSI boot process as it holds the configuration details required for the server to communicate with the storage array during the boot process1.

References: The process of configuring iSCSI boot in Cisco UCS Manager, including the creation of a virtual iSCSI vNIC, is detailed in Cisco’s documentation

 Policies that identify the connectivity between Endpoint Groups (EPGs) and the external connection when extending a bridge domain out of a Cisco ACI fabric are associated with L2Out and L3Out components. L2Outs are used to extend Layer 2 connectivity outside the ACI fabric, while L3Outs are used for Layer 3 external connections. These policies define how the ACI fabric will communicate with external networks

Upgrading the EPLD on a Cisco Nexus switch is a disruptive process that requires the switch to reboot multiple times. Each EPLD device on the switch must be upgraded individually, and the switch must reboot to initialize the new EPLD version for each device. This process ensures that all hardware components are properly updated and can operate with the new firmware, but it does cause temporary disruptions to network traffic as each module reboots.

References: For more detailed information, please refer to the Cisco Nexus 9000 Series FPGA/EPLD Upgrade Release Notes, where it discusses the impact of EPLD upgrades and the necessity of multiple reboots during the process1. Additionally, the Cisco Nexus 9000 Series NX-OS Software Upgrade and Downgrade Guide provides guidelines on the upgrade process, including the disruptive nature of EPLD upgrades

When a Cisco Nexus 9000 series switch encounters a startup configuration corruption, the recovery process involves clearing the current configuration, restarting the device, and then restoring the configuration from a previously saved file. The correct sequence is to first clear the configuration to prevent the corrupted startup configuration from loading upon restart. After restarting the device, the previously saved configuration file should be copied to the running configuration. Finally, to ensure the switch starts with the correct configuration in future restarts, the running configuration should be saved to the startup configuration.

References: The recovery process is detailed in the Cisco community documentation, where it outlines the steps for recovering the configuration in UCS by importing the configuration from a previously saved location

Ansible meets the requirements as it uses SSH for transport, does not require agent software to be installed on managed systems, and uses YAML for its playbooks, which is a human-readable data serialization standard, making it easy to read and use for people with limited knowledge of scripting languages.

A logical configuration backup in Cisco UCS Manager includes the AAA and RBAC settings and is stored in a human-readable format. This backup type is suitable for backing up configurations that need to be easily reviewed and audited.

 Microsegmentation is a feature of ACI that allows granular control of traffic between endpoints based on vCenter VM attributes, such as name, guest OS, or network adapter type. Microsegmentation works by creating a micro-EPG for each VM and applying contracts and policies to the micro-EPGs. When microsegmentation is enabled, ACI performs distributed switching and routing on the ESXi hosts using the Cisco Application Virtual Switch (AVS) or the Cisco Application Virtual Edge (AVE). This allows ACI to enforce policies at the hypervisor level, without requiring any changes to the physical network or the VM configuration. References :=

To create a virtual Fiber Channel interface and associate it with an Ethernet physical interface, the correct configuration commands would be:

• Enter the interface configuration mode for the virtual Fiber Channel interface using the command interface vfc7.
• Bind the virtual Fiber Channel to the Ethernet interface using the command bind interface ethernet 1/7.

This configuration associates the virtual Fiber Channel interface with VSAN 7 and maps VLAN 700 to the VSAN, as required by the converged network adapter (CNA).

References := The explanation is based on standard practices for configuring virtual Fiber Channel interfaces in a Cisco environment, as detailed in Cisco’s data center configuration guides and technical documentation.

 The commands shown in the exhibit configure Unicast Reverse Path Forwarding (uRPF) in loose mode on the interface Ethernet 2/2. The ip verify unicast source reachable-via rx command enables uRPF to check that the source address of a received packet has a route in the routing table and that the packet has been received from a valid interface that aligns with the routing table. This helps prevent IP spoofing by ensuring that packets are received from the expected interface.

References := This explanation is based on the principles of uRPF as described in Cisco’s security configuration guides and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course materials. For more detailed information, please refer to these resources.

 Option D is the correct configuration to enable the Cisco UCS Manager to manage a Cisco UCS C-Series server by using a single cable for management and data traffic. The commands enter the server scope, then the cimc scope, then the mgmt-conn scope with the sideband option, which enables the management connection through the sideband interface. Then, the mgmt-conn-state is set to enabled and the changes are committed to the buffer. References:

 Promiscuous mode (D) allows a virtual machine to observe all traffic on the virtual switch, which is necessary for the virtual machine to receive all frames. VLAN (E) is used to map the frames to a specific Layer 2 network. These settings ensure that the virtual machine receives all traffic for the specified VLAN, fulfilling the requirements stated in the question1.

References: The configuration details and the role of these settings can be found in the Cisco documentation related to VDS port group parameters managed by APIC

The MAC address that is an HSRP version 2 address is 0000.0C9F.F0C8. HSRP (Hot Standby Router Protocol) is a protocol that provides redundancy and load balancing for IP networks by allowing multiple routers to share a virtual IP address and MAC address. HSRP version 2 supports up to 4096 groups, and uses a different MAC address format than HSRP version 1. The MAC address format for HSRP version 2 is 0000.0C9F.FXXX, where XXX is the hexadecimal value of the group number. For group 200, the hexadecimal value is C8, so the MAC address is 0000.0C9F.F0C8. References :=

 The backup operation type that does not include the Preserve Identities feature is the logical configuration. This type of backup includes the settings and configurations that are logically defined within the Cisco UCS Manager, such as service profiles, policies, and management settings. However, it does not include the unique identifiers or ‘identities’ such as MAC addresses, WWN pools, and UUIDs, which are preserved in other types of backups like system configuration and full state.

Option D is the correct statement about monitoring Fibre Channel traffic on a Cisco UCS 6332 Fabric Interconnect. Fibre Channel traffic can be monitored even when it is encapsulated as FCoE (Fibre Channel over Ethernet) by using the SPAN (Switched Port Analyzer) feature. This allows network administrators to capture and analyze the Fibre Channel traffic flow and performance on any port or vHBA on the fabric interconnect. References:

The code snippet in Option C correctly sets up a local user named “tacuser” with an expiration date of 22 November. In the NX-OS API, the “expiresAt” attribute is used to specify the expiration date for a user account, which should be formatted in the ISO 8601 standard. The snippet provided in Option C, "expiresAt": "2021-11-22T00:00:00.000+00:00", correctly applies this format to set the expiration date to 22 November 2021. References := For further details, refer to the Cisco Data Center Core Technologies source documents or study guide available on the official Cisco Learning Network Store and Cisco’s solution listings for data center virtualization.

When SVR-A in EPG-A/BD-A cannot reach SVR-B in EPG-B/BD-B, it’s crucial to ensure that a contract exists between EPG-A and EPG-B that permits the traffic (Option A). Contracts in Cisco ACI act as a policy framework that dictates the types of traffic allowed between EPGs. Without an appropriate contract, traffic will not be allowed to pass between these entities.

Additionally, verifying that SVR-B is learned as an endpoint in EPG-B from Node-112 (Option C) is essential. Endpoint learning within ACI is a process where the leaf switch learns about the endpoints connected to it. If Node-112 has not learned SVR-B as an endpoint, it will not be able to forward traffic to it, resulting in connectivity issues.

References: = For more information on contracts and endpoint learning, refer to the Cisco ACI documentation on the Cisco official website. Specifically, look into sections detailing ACI contracts and endpoint learning processes.

To monitor traffic between leaf switches in a Cisco ACI network and support filtering traffic from a Bridge Domain or VRF, the configuration must allow for specifying the traffic of interest based on tenant, application, and EPG. Option C, filter tenant t1 application app1 epg epg1, meets these requirements by defining a filter that targets traffic from a specific EPG within an application profile in the tenant ‘t1’. This filter can be applied to the monitoring session to capture the relevant traffic.

References := For detailed procedures on implementing monitoring sessions in Cisco ACI, refer to the Cisco Data Center Core Technologies documentation, particularly sections covering ACI traffic monitoring and filtering.

 Option C is the correct attribute to use to assign the servers to different microsegments based on their VM names. By doing this, IT security can enforce policies that isolate production from development database servers existing in the same EPG and IP subnet. This can be achieved by using the microsegmentation feature of Cisco ACI, which allows granular control over the communication between endpoints within an EPG. References:

In a multihomed OTV network, it is essential to configure the remote OTV AEDs (Authoritative Edge Devices) to use both the primary and secondary adjacency servers for redundancy and resiliency. The correct configuration, Option D, includes the otv use-adjacency-server command with both IP addresses of the primary and secondary servers followed by unicast-only, which indicates that the AEDs should use unicast connections to the adjacency servers instead of multicast.

References := This configuration aligns with best practices for setting up OTV networks as described in Cisco’s Data Center Core Technologies documentation. For a more comprehensive understanding, refer to the study materials related to OTV configurations in the Cisco Data Center Core Technologies (DCCOR) course.

 In Cisco ACI, TCAM resources can be optimized by configuring a single contract that is provided and consumed by all EPGs within a VRF. This approach ensures that all EPGs consume the same services, thus reducing the number of individual contracts and associated TCAM entries. By having a common contract, the ACI fabric can efficiently manage access control policies and service insertion without the need for multiple, redundant entries in the TCAM, which can lead to resource exhaustion. References: The information is based on the best practices for TCAM management in Cisco ACI fabrics, as detailed in the Cisco community discussions and Cisco’s official documentation on TCAM resource issues and workarounds12. Additionally, the concept of using a single contract for multiple EPGs is supported by the Cisco ACI Endpoint Security Group (ESG) Design Guide, which outlines the steps for implementing a single ESG for open communication between subnets (EPG selectors)

Private Cloud: owned, managed, and operated by a single organization.

 To meet the objective of sending a copy of all VLAN 11 traffic on N5K_1 to the Traffic Capturing Device, creating a LAN traffic monitoring session is the necessary action. This session will capture the specified VLAN traffic and forward it to the designated capturing device for analysis or monitoring purposes. The existing configuration in Cisco UCS Manager needs to be complemented with this session to achieve the desired traffic capture.

The roles required to modify system logs, faults, and power management settings, as well as view access to all other configurations in the UCS domain, are typically those that provide broad administrative capabilities. The Operations role allows for the modification of operational aspects such as logs and power management, while the Administrator role provides full access to all configurations and settings within the UCS domain1.

References: = For more detailed information on user roles and permissions in Cisco UCS, you can refer to the Cisco UCS Manager Administration Management Guide2 and other official Cisco documentation1.

 For fabric redundancy in NPV mode on a Cisco MDS 9000 Series Switch, the engineer must connect the NPV devices to multiple upstream switches (A). This setup ensures that if one upstream switch fails, the NPV device can still reach the fabric through another upstream switch, maintaining fabric redundancy.

References := Switch Configuration - Configuring N Port Virtualization - Cisco2.

 In a vPC (Virtual Port Channel) configuration, multicast traffic is handled based on the IGMP (Internet Group Management Protocol) and PIM (Protocol Independent Multicast) configurations. When a host sends traffic to a multicast group, the vPC switches determine the forwarding path based on the multicast routing table and the RPF (Reverse Path Forwarding) check.

Option B is correct because when multicast traffic with source address 10.10.10.10 targeting group 239.1.1.1 is received on Po10 Switch1, the switch will perform an RPF check and forward the traffic out of the interfaces that lead to the Rendezvous Point (RP) and the receivers. This ensures that the multicast traffic is efficiently distributed to all receivers that are part of the multicast group. The traffic would be forwarded out on Po1, which is typically connected to the RP, and Po20, which connects to other receivers in the network.

References := For more detailed information on multicast traffic forwarding in a vPC environment, please refer to Cisco’s official documentation on Implementing Cisco Data Center Core Technologies (DCCOR), specifically the sections discussing multicast routing and vPC configurations.

The History Count setting in a user management system is used to prevent the reuse of old passwords. It specifies the number of unique new passwords that must be used before an old password can be reused. This helps enhance security by ensuring that passwords are not easily guessable and that users are not cycling through a small set of favorite passwords.

To meet the requirements of performing a backup and restore of the Cisco Nexus 5000 Series Switch configuration using UDP as the only protocol, the network engineer must follow these steps:

• Perform a startup-config backup to a TFTP server. The startup-config file contains the configuration that is applied when the switch boots up. To backup this file to a TFTP server, the engineer can use the copy startup-config tftp: command, and specify the IP address or hostname of the TFTP server and the destination filename. For example:

switch# copy startup-config tftp: Enter hostname for the tftp server: 10.10.10.10 Enter destination filename: backup-config

• Copy backup-config from the backup server to the running-config file. The running-config file contains the configuration that is currently active on the switch. To restore this file from the backup-config file on the TFTP server, the engineer can use the copy tftp: running-config command, and specify the IP address or hostname of the TFTP server and the source filename. For example:

switch# copy tftp: running-config Enter hostname for the tftp server: 10.10.10.10 Enter source filename: backup-config

These steps will allow the engineer to backup and restore the switch configuration using UDP as the only protocol, as TFTP is a UDP-based protocol. The backup-config file can be used when the current working configuration of the switch gets corrupted, as required by the goal. References :=

 Including EPG-2, EPG-3, and EPG-4 in the preferred group allows these EPGs to communicate with each other without requiring any contracts. This is because the preferred group feature in Cisco ACI allows EPGs within the same VRF to communicate by default. However, since the secure server in EPG-1 must provide services to EPG-2, a contract is required between EPG-1 and EPG-2 to facilitate this communication while maintaining the security and policies necessary for the server.

References := For more detailed information on configuring EPGs and contracts in Cisco ACI, you can refer to the Cisco Data Center Core Technologies (DCCOR) study materials and official Cisco documentation. These resources provide comprehensive guidance on the implementation and management of EPGs, contracts, and preferred groups within a Cisco ACI environment.

 The correct configuration for a unified I/O link that supports both LAN and SAN traffic using a single Ethernet transport is to configure the interface as a trunk port. This allows multiple VLANs (for LAN traffic) and VSANs (for SAN traffic) to coexist on the same physical link. The auto qos trust dscp command ensures that the Quality of Service (QoS) markings are preserved, which is essential for maintaining traffic prioritization across the network.

These resources provide comprehensive guidance on configuring and managing Cisco Nexus and MDS switches in a data center environment.

In Cisco UCS, modifying user accounts involves several considerations. Disabling a user account does indeed maintain all the data in the Cisco UCS Fabric Interconnect, which means that the user’s settings and privileges are retained even though the account is inactive (A). Local user accounts have precedence over remote authentication server accounts. This means that if a user account exists both locally and on a remote server like TACACS, RADIUS, or LDAP, the local account settings will take priority (D).

References := Managing User Accounts - Cisco1.

The command checkpoint file before_maintenance is used to create a checkpoint of the current running configuration with the specified file name. The command rollback running-config file before_maintenance atomic ensures that the rollback of the checkpoint to the running configuration only occurs if there are no errors during the process. This is essential for maintaining the stability of the switch during maintenance operations.

 Python is a versatile scripting language that supports the rapid creation and removal of logical containers, the development of custom modules and data structures, and is extensible with a wide range of external libraries and modules. It also allows for on-demand execution, making it ideal for automating tasks in Cisco ACI Fabric

 In a Cisco ACI fabric, when implementing a Virtual Machine Manager (VMM) domain, VLANs can be allocated dynamically or statically within a VLAN pool. To incorporate a static VLAN into a dynamic VLAN pool, the correct approach is to add a static VLAN allocation range to the VLAN pool. This allows for the specific VLAN to be reserved and used consistently for certain applications or services, while still maintaining the flexibility of dynamic allocation for other VLANs within the pool.

 Option C is the correct adjacency server configuration to make two OTV edge devices located in the same site bring up the dual-site adjacency. The adjacency server is a logical entity that maintains the control plane information for the OTV overlay network. The adjacency server can be configured in unicast-only mode, which means that the OTV edge devices use unicast packets to exchange control plane information. To enable dual-site adjacency, which means that the OTV edge devices can form adjacencies with devices in the same site as well as devices in different sites, the adjacency server must be configured with the same IP address on both devices in the same site. The other options have incorrect configurations or IP addresses. For example, option A uses different IP addresses for the adjacency server on the same site, option B uses the same IP address for the adjacency server on different sites, and option D uses an invalid IP address for the adjacency server. References:

To create an environment variable that can be used by several policies in the Embedded Event Manager, the engineer should use the command N9k2 (config)# event manager environment mailserver ‘’10.10.10.10’’. This command defines a global environment variable named mailserver with the value of 10.10.10.10, which represents the external email server. The environment variable can then be referenced by any policy that needs to use the email server in its actions, such as sending notifications or alerts. The environment variable can also be modified or deleted as needed. The other commands are incorrect because they either use the wrong mode, the wrong keyword, or the wrong syntax. References :=

 The requirements specify the need for two-factor authentication and encrypted AAA packets using TCP port 49, which is the default port for TACACS+. TACACS+ provides additional security features suitable for two-factor authentication, unlike LDAP. Therefore, removing the LDAP provider and creating a TACACS+ provider in user management would fulfill these requirements.

Option C and Option D are correct because they configure the SPAN session to monitor the source interface ethernet 1/16 and send the traffic to the destination interface ethernet 1/3. These options also include the use of the type SPAN-on-DROP command, which ensures that only dropped packets are sent to the analyzer, thus conserving disk space.

 NX-API is a feature that enables the use of JSON and XML encoding when a Cisco Nexus 7000 series switch is deployed. NX-API is a RESTful API that allows external applications to communicate with the switch using HTTP/HTTPS requests and responses. NX-API supports JSON and XML as the data formats for encoding and decoding the requests and responses. By using NX-API, external applications can access and configure the switch features and functions without using the CLI or SNMP. NX-API also provides a sandbox mode that allows users to test and validate their API calls before applying them to the switch. References :=

 In a vPC (Virtual Port Channel) environment, broadcast packets received on the vPC peer link are not forwarded out on the vPC member ports. This behavior is due to the vPC loop avoidance rule, which prevents traffic received on a vPC peer link from being sent back out of the vPC member ports. Therefore, the Agg-1 switch will prevent broadcast packets that arrive on the vPC peer link from exiting the switch on ports Eth2/4 and Eth2/5.

References: For more detailed information, you can refer to the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course, which covers the essentials of vPC operations and the loop avoidance mechanism

To facilitate communication between the APIC controller and an OpenStack OpFlex agent, it’s necessary to enable the Infra VLAN on the Attachable Access Entity Profile (AAEP). The AAEP is used in Cisco ACI to group interfaces that share common policies and extending the Infra VLAN to these interfaces allows the OpFlex agent, which is part of the Cisco Application Centric Infrastructure (ACI), to communicate with the APIC controller. This setup is crucial for the OpFlex agent to function correctly, as it relies on the Infra VLAN for communication with the APIC controller1.

 FCoE (Fibre Channel over Ethernet) requires a lossless Ethernet network to ensure that no frames are dropped, which is crucial for storage traffic. DCBXP (Data Center Bridging Exchange Protocol) is part of the DCB (Data Center Bridging) suite of protocols that help to create a lossless Ethernet by providing a means to exchange parameters between peers to ensure consistent configuration across the network. For FCoE to function correctly on a Cisco Nexus switch, it is essential that LLDP (Link Layer Discovery Protocol) transmit and receive capabilities are enabled on the interface where FCoE is configured. This allows the switch to advertise and receive configuration information for parameters like priority-based flow control (PFC) and Enhanced Transmission Selection (ETS), which are critical for the lossless operation required by FCoE.

References: The information is based on the Cisco Data Center Core Technologies (DCCOR) course, which covers the implementation of data center technologies including network, compute, storage network, automation, and security. More details can be found in the course material and official Cisco documentation on FCoE and DCBXP implementation

 In the context of configuring an FCoE connection between a Cisco UCS and a Cisco Nexus 9000 Series Switch, changing the transport type to FCoE in the Cisco UCS Manager is essential. This action ensures that the data traffic is encapsulated using FCoE, enabling seamless communication over Ethernet networks while maintaining Fibre Channel protocol characteristics.

 To meet the requirements of configuring a QoS policy on Cisco UCS that includes a no-drop class and enables jumbo frames without fragmentation, a QoS system class must be created with an MTU value of 9216 bytes. This MTU size is large enough to support jumbo frames, which can carry more data than standard frames, reducing the number of frames sent and improving network efficiency. The no-drop class ensures that frames are not dropped, which is crucial for certain types of traffic that require reliable delivery, such as storage traffic.

References: The configuration approach is based on best practices for enabling jumbo frames on Cisco UCS blades, as described in the Cisco documentation1. The MTU size of 9216 bytes is commonly used in data center environments to enable jumbo frames

Cisco IMC software policy is used to install new Cisco IMC software on a server.

Creating a static route in VRF WEB for the subnet of Server 2 on N5K-1 (D) will direct traffic from Server 1 to the specific subnet where Server 2 resides. This ensures that traffic can flow from Server 1 to Server 2, even if it is unidirectional. The static route provides a specified path for the traffic to follow, which is necessary when the traffic must be unidirectional and the gateways are on different VLANs.

References: For further details on configuring static routes in a VRF on Cisco Nexus switches, please refer to the Cisco Data Center Core Technologies documentation, which provides guidelines on implementing routing protocols and static routes within VRF instances.\

The ‘protect’ violation mode in port security is designed to drop packets with unknown source MAC addresses without affecting the interface’s state. This mode ensures that traffic from already learned MAC addresses continues to be forwarded while preventing any new MAC addresses from forwarding traffic until a sufficient number of secure MAC addresses are removed or the maximum count is increased. This configuration aligns with the requirement to not affect already learned MAC addresses.

 In a vPC (Virtual Port-Channel) configuration, multicast traffic is handled based on the vPC design and operational rules. When a host sends traffic to a multicast group, the vPC switches determine the forwarding path based on the source and the vPC domain configuration. If multicast traffic is received on a vPC member port, such as Po10 on Switch1, the traffic is typically forwarded out on all ports that are part of the same VLAN and have receivers interested in the multicast group, which includes Po1 and Po20 in this case. This ensures that the multicast traffic reaches all intended recipients across the vPC domain.

References: For a comprehensive understanding, the Cisco documentation on “Multicast forwarding in vPC based on location of the source” provides detailed scenarios and explanations on how multicast traffic is forwarded in a vPC environment1. Additionally, the “Cisco Nexus 9000 Series NX-OS Multicast Routing Configuration Guide” offers insights into the configuration and behavior of multicast routing on Nexus switches, which can be applied to understand the vPC behavior with multicast traffic

The DCNM performance monitoring configuration parameter that must be implemented to achieve the result of triggering events when monitored traffic exceeds the configured percent utilization threshold is the Util% parameter. This parameter allows the administrator to set a utilization threshold as a percentage, which, when exceeded, triggers an event. The requirement to configure a maximum limit of 39860437 bytes directly relates to the statistics collected as a ratio of the total link capacity, which is effectively managed by setting the Util% parameter. This parameter is part of the Performance Manager Configuration Wizard in DCNM, which provides the ability to set up two thresholds that trigger events when the monitored traffic exceeds the percent utilization configured. These thresholds can be set as either Critical or Warning events that are reported on the DCNM-SAN web client Events browser page1.

The configuration snippet in the exhibit shows that VSAN 100 is allowed on interface Ethernet1/12 with the command “switchport trunk allowed vsan 100”. This means option B, “Allow VSAN 100 on interface eth1/12”, is the correct answer. In Cisco Data Center Core Technologies, it’s essential to allow specific VSANs on an interface to enable traffic flow for those VSANs.References: Implementing and Operating Cisco Data Center Core Technologies (DCCOR) - Configuring FCoE

 A hybrid Cisco HyperFlex storage configuration is the best option for a virtual environment that is not performance-sensitive, but requires high storage capacity and a low cost. A hybrid configuration consists of a mix of solid-state drives (SSDs) and hard disk drives (HDDs) in each node. The SSDs are used for caching and metadata, while the HDDs are used for data storage. This allows for a balance between performance and capacity, as well as a lower cost per gigabyte than an all-flash configuration. A hybrid configuration also provides data deduplication and compression features to optimize storage efficiency and reduce the storage footprint. A hybrid configuration is suitable for general-purpose workloads, such as virtual desktop infrastructure (VDI), databases, and file servers. References :=

The method that a network engineer must use to upgrade the BIOS firmware of a Cisco UCS standalone C-Series rack-mount server is to use the Cisco host upgrade utility. The Cisco host upgrade utility is a tool that allows the network engineer to upgrade the firmware of various components of the server, such as the BIOS, the CIMC, the RAID controller, and the network adapter. The Cisco host upgrade utility can be downloaded from the Cisco website and run from a bootable USB drive or CD-ROM. The Cisco host upgrade utility provides a graphical user interface that guides the network engineer through the firmware upgrade process, and allows the network engineer to select the firmware versions and the components to be upgraded. References :=

 For a Cisco UCS C-Series Rack Server with PCIe cards, the fan configuration policy should be set to accommodate the additional cooling requirements of these cards. Option C, which sets the fan policy to ‘balanced’, would provide a middle ground between performance and energy efficiency, suitable for a server with additional components such as PCIe cards. This ensures adequate cooling while maintaining energy efficiency.

The command in question is likely to temporarily suspend the Protocol Independent Multicast (PIM) join messages. This action does not delete the PIM database or flush the Multicast Routing Information Base (MRIB), nor does it suspend multicast traffic forwarding. Instead, it interrupts the PIM join messages, which are used to build and maintain the multicast distribution tree.

References := For an in-depth explanation, one should refer to the Cisco Data Center Core Technologies study materials, which cover the PIM protocol and its behaviors in detail.

 Option B is the correct configuration that implements the traffic capture that meets the requirements. The configuration sets the flow timeout to 30 seconds, which matches the destination flow analyzer’s limit. The configuration also enables MAC packet classification and layer 2-switched flow monitoring on the interface ethernet 1/1, which belongs to VLAN 10. This allows the switch to capture the traffic from VLAN 10 and send it to the flow analyzer for troubleshooting. References:

To meet the requirements for configuring Cisco NX-OS REST API on a Cisco 9000 Series Switch, the correct configuration set is option B. This set of commands enables the NX-API feature, sets the NX-API to listen for HTTP traffic on TCP port 83, uploads the HTTPS certificate, and then enables the certificate. The inclusion of the nxapi certificate enable command is crucial as it activates the uploaded certificate, which is necessary for establishing secure HTTPS connections.

References: The configuration guidelines are based on the Cisco Nexus 9000 Series NX-OS Programmability Guide, which details the steps for enabling and configuring NX-API REST and DME database on Cisco Nexus switches1.

The new employee needs to add VLANs into an existing Cisco UCS Manager and configure NTP synchronization with date and time zone settings. Option B, Ext LAN Config (ext-lan-security), grants privileges to configure external LAN connectivity settings including VLANs. Option D, Service Profile Config (Is-config), allows for configuring service profiles including NTP synchronization settings. References:

 In the context of Cisco Data Center Core Technologies, SPAN (Switched Port Analyzer) is used to monitor network traffic. To configure a SPAN session on a Nexus 5000 series switch, an engineer would need to use specific commands. Option A, “Configure the switchport monitor under interface fc2/2,” is correct as it involves setting up the monitoring port under a specific interface. Option D, “Configure session type fc under monitor session 1,” is also correct as it specifies the type of session being configured for monitoring.

References := The explanation can be corroborated with detailed study from Cisco’s official documentation and resources available on their website or the Cisco Data Center Core Technologies source book.

To establish a VSAN trunk between Switch 1 and Switch 2, you would typically configure E Port with Trunk Mode On. This is because Switch 1 is already configured with an E port in Trunk Mode Auto, and for trunking to be established, the other switch should also be set to trunk mode but with a static configuration (On) to ensure compatibility and trunk formation.

During the infrastructure firmware upgrade stage using the Auto Install feature, the I/O module is upgraded. The infrastructure firmware upgrade includes updates to the fabric interconnects and I/O modules, which are essential components of the UCS B-Series chassis network connectivity.

 A nondisruptive upgrade is possible only when there are no changes to the configuration settings or network connections during the upgrade process. Any such changes can lead to a disruption, which is particularly critical in a dual supervisor Cisco Nexus 7000 series switch where stability is paramount.

The Device Connector Access Mode should be configured as ‘Allow Control’ within the Cisco UCS Manager to enable full configuration capabilities. Claiming the device on Intersight as ‘UCSM Managed Mode’ ensures that the device can be managed through both the Cisco UCS Manager and the Intersight platform. This configuration aligns with the best practices for setting up Cisco UCS domains for integration with Intersight, allowing for seamless monitoring and management while maintaining security and control12.

References := For further details on the configuration process and best practices, you can refer to the Cisco Intersight Managed Mode Configuration Guide and other official Cisco documentation related to UCS domain profiles and Intersight integration

 PowerOn Auto Provisioning (POAP) is a feature that automates the process of upgrading software images and installing configuration files on Cisco devices that are deployed in a network for the first time. It is particularly useful for scenarios where multiple switches need to be provisioned without manual intervention. When a switch with POAP boots up and does not find a startup configuration, it enters the POAP mode, locates a DHCP server, and bootstraps itself with its interface IP address, gateway, and DNS server IP address. It then obtains the IP address or URL of a TFTP server and downloads the necessary scripts and software images to configure the device12.

References: More information about POAP and its configuration can be found in Cisco’s official documentation

 The configuration set that meets the requirements for configuring port security on a Cisco MDS 9000 Series Switch is Option C. This option includes the command port-security activate vsan 4 force, which initiates the VSAN 4 port security database despite any conflicts. It omits the auto-learn command, indicating that new devices must be added manually. Additionally, the port-security distribute command ensures that configuration changes are applied throughout the fabric and any locks on the fabric are released, as required1.

An advantage of streaming telemetry over SNMP is that it supports periodic push-based subscription messages. Streaming telemetry is a method of collecting and transporting network data from devices to a receiver, such as a collector or a dashboard. Streaming telemetry allows the devices to send data periodically or on-demand, based on a subscription model. The receiver can subscribe to specific data sets or events that it is interested in, and the device will push the data to the receiver as it becomes available. This reduces the overhead and latency of polling the device status using SNMP, and provides more granular and real-time visibility into the network state and performance. References :=

The Cisco UCS Python SDK (D) is a set of Python libraries that provide a method for automating the configuration and management of Cisco Unified Computing System (UCS) hardware. It allows network administrators to write custom scripts or develop applications to manage UCS environments programmatically. In the context of creating a Django self-service portal for VLAN automation, the UCS Python SDK would be used to interact with the UCS Manager’s API, enabling the automation of VLAN creation and other tasks1.

References: The use of the Cisco UCS Python SDK for automating tasks in UCS Manager is discussed in Cisco’s official blogs and community forums, where examples and best practices can be found12. The SDK provides a more direct and tailored approach for UCS automation compared to other tools, making it suitable for integration with custom Django applications.

Options D and E are the correct firmware packages that are included in the Cisco UCS C-Series Rack-Mount UCS-Managed Server Software bundle. The bundle contains the firmware for the CIMC (Cisco Integrated Management Controller) and the BIOS (Basic Input/Output System) of the server. The other options are either not part of the bundle or not applicable for the server. References:

 The two components that support specific power limits on a Cisco UCS C-Series rack server are the processor and the graphic card. The processor and the graphic card are the two components that consume the most power on a server, and they can be configured to have specific power limits to control the power usage and performance of the server. The power limits can be set using the Cisco Integrated Management Controller (CIMC) web interface or CLI, or using the Cisco UCS Manager if the server is integrated with a Cisco UCS domain. The power limits can be applied to individual processors or graphic cards, or to the entire server. The power limits can help to optimize the power efficiency and thermal management of the server, as well as to prevent power capping or throttling issues. References :=
