CompTIA A+ Core 1 (220-1101) — Question 57

A technician was called in to look at a user's PC. The user reported the PC was very sluggish. The HDD light on the PC was constantly on without blinking. The
PC itself was slow receiving input and took a very long time to load the OS. The technician also noticed updates had failed. Which of the following is MOST likely the cause of these issues?

Answer options

• A. The hard disk drivers have been corrupted.
• B. The HDD cables need reseating.
• C. A RAID disk failed.
• D. The HDD has no free space.

Correct answer: D

Explanation

The correct answer is D because a lack of free space on the HDD can lead to poor performance and slow boot times, as the operating system requires space for temporary files and updates. The other options are less likely to be the cause; corrupted drivers (A) or reseating cables (B) would typically not result in constant HDD activity, and RAID failure (C) would usually present different symptoms.
