CompTIA Security+ (SY0-601) — Question 823

An organization suffered an outage, and a critical system took 90 minutes to come back online. Though there was no data loss during the outage, the expectation was that the critical system would be available again within 60 minutes. Which of the following is the 60-minute expectation an example of?

Answer options

• A. MTBF
• B. RPO
• C. MTTR
• D. RTO

Correct answer: D

Explanation

The 60-minute expectation is an example of RTO (Recovery Time Objective), which defines the maximum allowable downtime for a system. MTBF (Mean Time Between Failures) measures system reliability, RPO (Recovery Point Objective) indicates the acceptable amount of data loss, and MTTR (Mean Time To Repair) focuses on the average time taken to repair a system after a failure.
