Exam VNX301 Topic 2 Question 30 Discussion

The correct answer is A . In Versa Secure SD-WAN onboarding, the branch moves through three staging phases before becoming fully operational. Versa documentation states that in Stage 3 , Versa Director pushes the stage-three configuration to the branch device over the IKE session and reboots the branch. After this stage, the branch becomes fully operational and is part of the customer SD-WAN network. At this point, IKE and IPsec sessions are created between the branch and Controller , and VXLAN and ESP sessions are created between branch to branch .
This distinction is important because the Controller connection is used for SD-WAN control-plane functions, while branch-to-branch overlay communication uses tunnel encapsulation for data forwarding. The documentation also notes that branch-to-branch ESP is maintained using a lightweight DH key-pair proprietary protocol.
Options B, C, and D are incorrect. HTTPS to Director alone does not represent the complete SD-WAN operational tunnel state. BGP to Analytics is not the required operational tunnel set. GRE-only tunnels without IPsec do not match the Versa Stage 3 SD-WAN tunnel behavior described in the staging documentation.
