Implementing Cisco SD-WAN Solutions (ENSDWI) — Question 327

How do WAN Edge devices operate when vSmart is inaccessible or fails to be reached by the WAN Edge?

Answer options

• A. They continue operation normally.
• B. They continue operating normally for a configurable time.
• C. They continue to receive reachability updates.
• D. They cease to forward traffic in the data plane.

Correct answer: B

Explanation

The correct answer is B because WAN Edge devices can maintain normal operation for a specific duration when vSmart is unreachable. Options A and C are incorrect as they imply indefinite normal operation or continued updates, which isn't the case. Option D is also wrong because traffic forwarding does not cease immediately; there's a grace period before that happens.
