CompTIA A+ Core 1 (220-1001) — Question 403

A technician is dispatched to troubleshoot a slow performance issue on a PC. Upon arrival, the technician immediately opens Task Manager and sees that CPU and RAM performance are within normal ranges. The technician then checks and verifies the speed and duplex settings and performance on the network card.
The technician then temporarily disables the antivirus to see if performance is affected, and it is not. After re-enabling the antivirus, which of the following is the
NEXT best step for the technician to take?

Answer options

• A. Check to see if insufficient hard drive space is causing the issue
• B. Update the operating system, drivers, and firmware on the PC
• C. Log into the PC with another user profile and test performance
• D. Shut down the PC, unplug the power for 30 seconds, and then boot the PC

Correct answer: A

Explanation

The best next step is to check for insufficient hard drive space, as low disk space can significantly affect system performance. Updating the operating system, drivers, and firmware (option B) is also important but may not address the immediate issue of slow performance. Logging in with a different user profile (option C) and shutting down the PC to unplug it (option D) are less likely to resolve the underlying problem related to disk space.
