CompTIA CASP+ (CAS-004) — Question 427

The management team at a company with a large, aging server environment is conducting a server risk assessment in order to create a replacement strategy. The replacement strategy will be based upon the likelihood a server will fail, regardless of the criticality of the application running on a particular server. Which of the following should be used to prioritize the server replacements?

Answer options

• A. SLE
• B. MTTR
• C. TCO
• D. MTBF
• E. MSA

Correct answer: D

Explanation

MTBF, or Mean Time Between Failures, is the most suitable metric for prioritizing server replacements based on their likelihood of failure. SLE, MTTR, TCO, and MSA do not specifically measure failure rates, making them less appropriate for this purpose.
