CompTIA Network+ (N10-008) — Question 751

A user is having trouble uploading files to a server. However, other users in the department are not experiencing this issue. The network administrator checks the access switch and sees multiple CRC errors on that user's switchport. Which of the following should the network administrator do first?

Answer options

• A. Replace the uplink cable for the access switch.
• B. Replace the user's network cable.
• C. Replace the NIC for the user's PC.
• D. Replace the access switch.

Correct answer: B

Explanation

The correct answer is B because CRC errors often indicate issues with the physical layer, typically related to the network cable. Since the other users are not experiencing issues, it's more likely that the problem lies with the user's cable rather than the uplink cable, NIC, or the access switch.
