CompTIA Server+ (SK0-005) — Question 103

Which of the following BEST describes a guarantee of the amount of time it will take to restore a downed service?

Answer options

• A. RTO
• B. SLA
• C. MTBF
• D. MTTR

Correct answer: A

Explanation

The correct answer is A, RTO (Recovery Time Objective), as it specifically refers to the targeted duration for restoring a service after an outage. SLA (Service Level Agreement) outlines the expected service level but does not guarantee timeframes. MTBF (Mean Time Between Failures) relates to reliability, and MTTR (Mean Time To Repair) measures the average time taken to fix a service, but neither directly guarantees restoration time.
