Dell EMC Specialist – Systems Administrator, VNX — Question 29

There is a spanning tree mismatch at the global level. PVST+ is configured on a VLT peer. All VLT port channels go down on both VLT peers. A syslog error message is generated. What is the correct action to resolve the issue?

Answer options

• A. Verify the VLT LAG ID is configured correctly on both VLT peers.
• B. Enable RSTP on both VLT peers.
• C. Use the show VLT detail and show VLT brief commands to view the VLT port channel status information.
• D. Perform a mismatch check after the VLT peer is established.

Correct answer: D

Explanation

The correct action is to perform a mismatch check after the VLT peer is established, as this will help identify any discrepancies that may have caused the port channels to go down. Verifying the VLT LAG ID (Option A) and enabling RSTP (Option B) may not directly address the spanning tree mismatch issue. While using the show commands (Option C) can provide useful status information, it does not resolve the mismatch itself.
