2V0-41.23 Exam Dumps : VMware NSX 4.x Professional

According to the VMware NSX Documentation, these are the prerequisites for adding nodes to an NSX Management Cluster using the NSX UI:

• All nodes must be in the same subnet and have IP connectivity with each other.
• A compute manager must be configured and associated with the NSX Manager node.
• The NSX Manager node must have a valid license.
• The NSX Manager node must have a valid certificate.

The RouterLink port is automatically created when a Tier-1 Gateway is connected with a Tier-0 Gateway from the NSX UI1. The RouterLink port is a logical interface that is assigned an IP address and is associated with a physical or virtual interface. The RouterLink port acts as an end point of the IPSec tunnel and routes traffic between the Tier-1 Gateway and the Tier-0 Gateway2. The other options are incorrect because they involve manual creation of logical switches or segments, which are not required for RouterLink port creation. References: Configure NSX for Virtual Networking from vSphere Client, Virtual Private Network (VPN)

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:
