CompTIA Network+ (N10-008) — Question 557

A network technician is selecting new network hardware, and availability is the main concern. Which of the following availability concepts should the technician consider?

Answer options

• A. RTO
• B. MTTR
• C. MTBF
• D. RPO

Correct answer: C

Explanation

MTBF, or Mean Time Between Failures, is a key metric for assessing the availability of hardware, as it indicates the average time between failures, thus providing insight into reliability. RTO (Recovery Time Objective) and MTTR (Mean Time To Repair) are more focused on recovery after an incident, while RPO (Recovery Point Objective) relates to data loss, making them less relevant to hardware availability.
