According to the VMware NSX Documentation, this is the NSX feature that can be leveraged to achieve consistent policy configuration and simplicity across sites:
NSX Federation: This feature allows you to create and manage a global network infrastructure that spans across multiple sites using a single pane of glass. You can use this feature to synchronize policies, segments, gateways, firewalls, VPNs, load balancers, and other network services across sites.

To implement SSL certificates for the NSX Manager Cluster VIP, the correct method is to SSH into the NSX Manager (using the Cluster VIP IP) and run the nsxcli cluster certificate vip install
<certificate_id> command. This command installs the SSL certificate for the VIP, ensuring that the cluster's SSL certificate is properly configured for secure communications.

In Non-Preemptive failover policy, once a failover occurs and a new Active node is designated, the original failed node will not automatically become the Active node upon recovery. This setting ensures that the failover does not revert to the original node after it comes back online, maintaining the stability of the network by keeping the current Active node as is.

The answer is
A: SR is instantiated and automatically connected with DR.
SR stands for Service Router and DR stands for Distributed Router. They are components of the NSX Edge node that provide different functions1 The SR is responsible for providing stateful services such as NAT, firewall, load balancing, VPN, and DHCP. The DR is responsible for providing distributed routing and switching between logical segments and the physical network1 When a stateful service is enabled for the first time on a Tier-0 Gateway, the NSX Edge node automatically creates an SR instance and connects it with the existing DR instance. This allows the stateful service to be applied to the traffic that passes through the SR before reaching the DR2 According to the VMware NSX 4.x Professional Exam Guide, understanding the SR and DR components and their functions is one of the exam objectives3 To learn more about the SR and DR components and how they work on the NSX Edge node, you can refer to the following resources:
