VMware 5V0-41.21 VMware NSX-T Data Center 3.1 Security Exam Practice Test

The red dashed line for the UDP:137 flow in the NSX Intelligence information represents blocked communication. This indicates that the NSX Distributed Firewall has blocked the communication between the source and destination IP addresses on port 137.

For more information on NSX Intelligence and how to use it, please refer to the NSX-T Data Center documentation:

This allows for the Partner SVM to be close to the compute nodes, allowing for faster processing of the traffic and improved security. Additionally, the Partner SVM is also deployed close to the Partner Manager for added security and ease of management. 

Next Generation Firewalls are capable of analyzing application traffic at Layer 7 of the OSI model. Layer 7 is the Application Layer, which is where the application-level protocols, such as HTTP and FTP, are implemented. Next Generation Firewalls are able to inspect the application traffic and apply rules based on the content of the application-level packets.

NSX Manager needs to be reconfigured. Guest Introspection requires additional configuration of the NSX Manager in order to collect information from the Windows based VMs. This configuration includes setting up the Guest Introspection service with the appropriate credentials and configuring the rules to allow the traffic through the firewall. Once this is done, the Windows VMs will start reporting information to the NSX Manager.

For more information on setting up Guest Introspection, please refer to the NSX-T Data Center documentation: 

In the Cloud Director UI (CU), the customer should update the intelligence manager node's host-ip-addr parameter with the correct IP address. This can be done from the NSX Intelligence Settings page in the CU.

For more information on updating the IP address of the NSX Intelligence appliance, please refer to the NSX Intelligence documentation: 

The tier-0 gateway is the entry point of the NSX-T Data Center network, and it is where the North-South service insertion takes place. The uplink of the tier-0 gateway is the point of connection between the NSX-T Data Center network and the external network.

The guest VM vNIC is the interface card inside the guest virtual machine, which is used to connect the guest VM to the NSX-T Data Center network. North-South services can be inserted at this point as well.

The first object that must be created in the distributed firewall is a firewall policy. A firewall policy is a set of rules that define what traffic is allowed or blocked on a given network. When creating a policy, the administrator must specify the source and destination address and port, as well as the type of traffic that is allowed or blocked. The policy will then be applied to the distributed firewall, allowing it to enforce the rules specified in the policy. References: [1]   [2] 

Information Security Management (ISM) describes a set of controls that organizations employ to protect confidentiality, integrity, and availability. Confidentiality ensures that data is protected from unauthorized access or disclosure, integrity ensures that data is not modified without authorization, and availability ensures that data is accessible when it is needed. ISM is a crucial component of any organization's security strategy and is used to protect against threats such as data theft, data loss, and system outages. References: [1]   [2]   [3] 

NSX-T Endpoint Protection provides agentless antivirus protection for virtual machines running on VMware ESXi hosts. It uses the VMware vShield Endpoint API to scan the virtual machines without requiring the installation of antivirus agents. The service is integrated with third-party antivirus solutions, such as McAfee and Symantec, to provide real-time protection against malware and other threats.
