VMware SD-WAN by VeloCloud Specialist — Question 5

Both the hub and spoke VMware SD-WAN Edges have a public and a private link. Branch-to-Hub is configured in Cloud VPN, so both sites have two direct tunnels between Edges. There are no paths from the private link to any of the VMware SD-WAN Gateways (VCG).
Only the public link has paths to all the VCG. If the public link on the spoke goes down, the site will lose all the connectivity to all VCGs.
Which consequence is expected in this situation?

Answer options

• A. The path/tunnel between hub and spoke on the public link is down, and tunnel over private link is also disrupted.
• B. Any new local subnet will not be advertised to any other Edge through overlay.
• C. Routes stored in the Edge locally will be revoked.
• D. Even if the internet Backhaul is configured, traffic going to the internet cannot use this private path to go the hub and then to the internet.

Correct answer: D

Explanation

The correct answer is D because if the public link fails, the private link cannot be used for internet traffic, even with internet Backhaul configured. Options A, B, and C do not accurately describe the consequences of the public link going down, as they pertain to different aspects of connectivity and routing that are not directly impacted by the failure of the public link.
