Route-based VPN is a VPN type that uses Virtual Tunnel interfaces (VTI) to establish IPSec tunnels between an NSX Edge node and remote sites2. A VTI is a logical interface that is assigned an IP address and is associated with a physical or virtual interface. The VTI acts as an end point of the IPSec tunnel and routes traffic between the NSX Edge node and the remote site2. Route & SSL based VPNs, Policy & Route based VPNs, and SSL-based VPN are not VPN types that use VTI. References: 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:
