CompTIA CASP+ (CAS-003) — Question 298

Following a recent outage, a systems administrator is conducting a study to determine a suitable bench stock on server hard drives.
Which of the following metrics is MOST valuable to the administrator in determining how many hard drives to keep-on hand?

Answer options

• A. TTR
• B. ALE
• C. MTBF
• D. SLE
• E. RPO

Correct answer: C

Explanation

The correct answer is C. MTBF (Mean Time Between Failures) is crucial because it provides insight into the reliability of hard drives and helps estimate how many should be kept in stock. The other options, while related to risk and recovery, do not directly inform inventory needs as effectively as MTBF does.
