CompTIA Network+ (N10-008) — Question 46

A network administrator is troubleshooting the communication between two Layer 2 switches that are reporting a very high runt count. After trying multiple ports on both switches, the issue persists. Which of the following should the network administrator perform to resolve the issue?

Answer options

• A. Increase the MTU size on both switches.
• B. Recertify the cable between both switches.
• C. Perform a factory reset on both switches.
• D. Enable debug logging on both switches.

Correct answer: B

Explanation

The correct answer is B because recertifying the cable can identify if there are any physical layer issues causing the high runt count. Increasing the MTU size (A) would not address the underlying cable problem, while a factory reset (C) or enabling debug logging (D) may not provide a direct solution to the communication issue at hand.
