CompTIA Security+ (SY0-501) — Question 631

Which of the following are the BEST selection criteria to use when assessing hard drive suitability for time-sensitive applications that deal with large amounts of critical information? (Choose two.)

Answer options

• A. MTBF
• B. MTTR
• C. SLA
• D. RTO
• E. MTTF
• F. RPO

Correct answer: A, B

Explanation

MTBF (Mean Time Between Failures) and MTTR (Mean Time To Repair) are crucial metrics for time-sensitive applications, as they indicate reliability and recovery speed. The other options, such as SLA (Service Level Agreement), RTO (Recovery Time Objective), MTTF (Mean Time To Failure), and RPO (Recovery Point Objective), while important, do not directly measure the operational performance of the hard drive itself in the context of urgency.
