Cisco 500-470 Cisco Enterprise Networks SDA - SDWAN and ISE Exam for System Engineers Exam Practice Test

An ISE PoV (Proof of Value) is a service that demonstrates the value of Cisco Identity Services Engine (ISE) to potential customers. It consists of two components: a virtual machine (VM) and a license. The VM is a pre-configured ISE environment that can be deployed on any cloud platform, such as Cisco dCloud1. The license is a one-time payment that grants access to the ISE features and capabilities for three years2.

The two options that are used as part of an ISE PoV are A and E. Option A refers to the VM, which is the core component of the ISE PoV. Option E refers to the POV Kit, which is a bundle that includes the VM, the license, and some additional resources, such as documentation, videos, and webinars2. Option B, C, and D are not used as part of an ISE PoV.

 Identity management is the practice of making sure that people and entities with digital identities have the right level of access to enterprise resources like networks and databases. User roles and access privileges are defined and managed through an identity management system, such as Cisco Identity Services Engine (ISE)1. Identity management solves two customer problems:

• Provides network visibility and security: Identity management allows customers to see who and what is on their network, and to control their access based on policies and context. Identity management also integrates with other security solutions, such as Cisco Firepower, Cisco Stealthwatch, or Cisco Umbrella, to detect and respond to threats, and to enforce adaptive network access policies based on the threat level of the endpoints2.
• Achieves dynamic and adaptive network segmentation: Identity management enables customers to segment their network based on the identity and context of the users and devices, rather than the IP addresses and VLANs. This allows customers to implement a zero-trust model, where only trusted users and devices can access the resources they need, and where the access policies can be dynamically updated based on the changing conditions and requirements. Identity management also supports Cisco TrustSec, which is a technology that assigns scalable group tags (SGTs) to endpoints and enforces group-based policies (contracts) across the network3.

Device Sensor is a feature that enables Cisco devices to collect and report information about the endpoints connected to them. This information can be used by ISE to identify and classify the endpoints, and apply appropriate policies based on their attributes. Device Sensor can collect information from various sources, such as DHCP, CDP, LLDP, and HTTP User-Agent. Among the options given, only DHCP and CDP are valid sources of information for Device Sensor. References := : Cisco Identity Services Engine Administrator Guide, Release 2.7 - Device Sensor [Cisco Identity Services Engine]- Cisco

A vEdge Cloud Router is a virtualized version of the vEdge router that can be deployed in various cloud environments. According to the Cisco vEdge Cloud Data Sheet1, the vEdge Cloud Router can be instantiated as a virtual machine (VM) on a KVM hypervisor or as a VM on a VMware ESXi hypervisor, as well as in public cloud environments, such as Amazon AWS or Google Cloud Platform. Therefore, the two platforms that can host a vEdge Cloud Router are AWS and Microsoft Azure.

A centralized SD-Access design is where a single fabric domain spans across the main site and all branch sites over the WAN. This design has some challenges, such as:

• Since the traffic is encapsulated in VXLAN headers, SD-WAN features such as application-aware routing, QoS, and security policies cannot be applied to the traffic based on the original IP headers. This means that the SD-WAN controller cannot optimize or route the traffic based on the application or user identity. The traffic is treated as a single class of service across the WAN.
• The centralized design also introduces a single point of failure and a potential bottleneck at the main site, where the border nodes and the control plane nodes are located. If the main site goes down or the WAN link fails, the branch sites will lose connectivity to the fabric domain and the external networks.
• The centralized design also requires a high bandwidth and low latency WAN connection between the main site and the branch sites, which may not be feasible or cost-effective for some scenarios.

Syslog, FNF (Flexible NetFlow), and SNMP (Simple Network Management Protocol) are three technologies that can be deployed to gather data and provide insight into the network performance, health, and behavior. Syslog is a standard protocol for logging messages from network devices, such as routers, switches, firewalls, and servers. Syslog messages can be sent to a centralized server for analysis, correlation, and alerting. FNF is a Cisco technology that captures and exports information about network flows, such as source and destination IP addresses, ports, protocols, bytes, packets, and timestamps. FNF can be used to monitor network traffic patterns, identify anomalies, and optimize network resources. SNMP is a protocol that allows network devices to communicate with management systems, such as Cisco DNA Center. SNMP can be used to collect statistics, configuration, and status information from network devices, as well as to send commands and notifications. SNMP can help network administrators to troubleshoot, configure, and manage their network devices remotely. References: Cisco DNA Center User Guide, Release 1.3.1.0 - Monitor the Network 1, Cisco DNA Center User Guide, Release 1.3.1.0 - Configure Flexible NetFlow 2, Cisco DNA Center User Guide, Release 1.3.1.0 - Configure SNMP 3

The workflow that is necessary for setting up a network hierarchy is Design. The Design area is where you create the structure and framework of your network, including the physical topology, network settings, and device type profiles that you can apply to devices throughout your network. You can create a network hierarchy that represents your network’s geographical locations, such as sites, buildings, and floors. You can also define global network settings, such as device credentials, IP address pools, service provider profiles, and network servers. You can also create network profiles, which are collections of design settings that you can assign to devices based on their roles and functions1.

 ISE automation BYOD flow is a process that allows users to self-enroll their devices to the network without requiring IT intervention. The process consists of three main functions: certificate enrollment, device registration, and supplicant provisioning.

• Certificate enrollment is the function that allows users to obtain a digital certificate from a certificate authority (CA) for their devices. This certificate is used to authenticate the device to the network and provide secure communication. ISE supports different CA options, such as Microsoft CA, Cisco ISE CA, or third-party CA .
• Device registration is the function that allows users to register their devices to the network and associate them with their identity. This enables ISE to apply policies based on the device type, ownership, and posture. ISE supports different device registration methods, such as portal-based, API-based, or bulk import .
• Supplicant provisioning is the function that allows users to install and configure a network access client (supplicant) on their devices. This client is used to connect to the network using the appropriate protocols and settings. ISE supports different supplicant provisioning methods, such as native supplicant, Cisco Network Setup Assistant (NSA), or Cisco AnyConnect Secure Mobility Client (AnyConnect) .
