CompTIA Network+ (N10-009) — Question 379

A technician is alarmed after noticing more than 5,000 CRCs on a switchport. Which of the following should the technician do next?

Answer options

• A. Move to a different switchport.
• B. Check for errdisable,
• C. Swap out the patch cable.
• D. Enable class-of-service.

Correct answer: C

Explanation

The correct answer is C, as swapping out the patch cable can resolve issues related to CRC errors, which are often caused by faulty cables. Options A and B do not address the root cause of CRC errors, and D is unrelated to the physical layer issues that typically cause these errors.
