CompTIA Network+ (N10-008) — Question 853

A Fortune 500 firm is deciding on the kind of data center equipment to install given its five-year budget outlook. The Chief Information Officer is comparing equipment based on the life expectancy of different models. Which of the following concepts BEST represents this metric?

Answer options

Correct answer: A

Explanation

MTBF, or Mean Time Between Failures, is the metric that indicates the average operational lifespan of equipment before it fails, making it the best choice for assessing life expectancy. MTTR (Mean Time To Repair) focuses on repair time rather than lifespan, while RPO (Recovery Point Objective) and RTO (Recovery Time Objective) pertain to data recovery metrics, not equipment longevity.
