CompTIA Server+ (SK0-004) — Question 48

A technician is experiencing overheating on a rack mounted server. After powering off and removing the cover of the server, a large amount of dust is noticed on one of the fans. After cleaning out the dust and powering the server back on, the server is still overheating. Which of the following would BEST explain this issue?

Answer options

• A. The power supply has failed.
• B. The server is using excessive power.
• C. The hard drives are running too hot.
• D. Some of the cooling fans are defective.

Correct answer: D

Explanation

The correct answer is D because even after cleaning the dust, if the cooling fans are defective, they won't provide adequate airflow to cool the server. The other options are less likely to be the cause of the overheating since they do not directly relate to the immediate issue of cooling failure.
