CompTIA Network+ (N10-009) — Question 340

While conducting a network audit, an administrator notices the spanning tree root in VLAN 300 does not match the configuration baseline, which could cause network outages due to spanning tree update failures. Which of the following should the administrator do to restore consistency?

Answer options

• A. Change the designated port on the misconfigured switch to a root port.
• B. Change the root port to a listening port on the misconfigured switch.
• C. Change the blocked port of the misconfigured switch to a learning port.
• D. Increase the bridge ID/priority on the misconfigured switch.

Correct answer: D

Explanation

The correct answer is D because increasing the bridge ID/priority on the misconfigured switch will help it to become the root bridge, aligning it with the configuration baseline. The other options do not address the root bridge consistency issue and could lead to further network problems rather than resolving the inconsistency.
