CompTIA Network+ (N10-008) — Question 678

Which of the following disaster recovery metrics is used to describe the amount of data that is lost since the last backup?

Answer options

• A. MTTR
• B. RTO
• C. RPO
• D. MTBF

Correct answer: C

Explanation

The correct answer is C, RPO (Recovery Point Objective), which specifically measures the maximum acceptable amount of data loss since the last backup. MTTR (Mean Time to Recovery) and RTO (Recovery Time Objective) pertain to recovery time, while MTBF (Mean Time Between Failures) relates to system reliability, making them irrelevant to data loss metrics.
