Implementing Cisco IP Switched Networks (CCNP SWITCH, legacy) — Question 188

Which statement describes what happens if all VSL connections between the virtual switch members are lost?

Answer options

• A. Both virtual switch members cease to forward traffic.
• B. The VSS transitions to the dual active recovery mode, and both virtual switch members continue to forward traffic independently.
• C. The virtual switch members reload.
• D. The VSS transitions to the dual active recovery mode, and only the new active virtual switch continues to forward traffic.

Correct answer:

Explanation

The correct answer is D, as when all VSL connections are lost, the VSS enters dual active recovery mode, which allows only the new active virtual switch to continue forwarding traffic. Option A is incorrect because one member continues to operate in recovery mode. Option B is wrong because both cannot forward traffic in that situation. Option C is also incorrect as there is no requirement for the virtual switch members to reload.
