CompTIA A+ Core 1 (220-1101) — Question 448

After a company upgraded its network infrastructure, a single user reported experiencing slow network speeds on their desktop. No other users with the same desktop configuration within the department have reported an issue. Which of the following actions should a technician do first?

Answer options

• A. Update Internet bandwidth speed.
• B. Update the BIOS firmware.
• C. Replace the motherboard.
• D. Replace the patch cable.

Correct answer: D

Explanation

The correct action is to replace the patch cable, as a faulty or damaged cable can lead to slow connectivity for a single user while others remain unaffected. Updating the Internet bandwidth or BIOS firmware may not resolve the issue if it's localized to the user's hardware. Replacing the motherboard is unnecessary and would be too drastic without first checking simpler solutions.
