CompTIA Server+ (SK0-005) — Question 209

A storage engineer responds to an alarm on a storage array and finds the battery on the RAID controller needs to be replaced. However, the replacement part will not be available for 14 days. The engineer needs to identify the impact of the failed battery on the system. Which of the following best describes the impact?

Answer options

• A. The read and write performance will be impacted.
• B. The read performance will be impacted.
• C. The performance will not be impacted.
• D. The write performance will be impacted.

Correct answer: D

Explanation

The correct answer is D because a failed battery in a RAID controller typically affects the ability to write data safely, as the battery is responsible for maintaining cache data in the event of a power loss. Options A and B are incorrect because while read performance may remain unaffected, write operations are primarily compromised. Option C is also incorrect as the failure of the battery does impact write performance.
