An administrator investigating an incident is concerned about the downtime of a critical server due to a failed drive. Which of the following would the administrator use to estimate the time needed to fix the issue?

Mean Time Between Failures (MTBF) represents the average time between system failures, not the time taken to repair a failure. While MTBF is useful for understanding system reliability and planning maintenance, it does not provide information about downtime duration due to a failure, making it less relevant for this scenario.

Recovery Time Objective (RTO) defines the maximum acceptable downtime for a system after a failure, focusing on the overall recovery goals rather than the specific repair time. RTO is a strategic metric that helps organizations plan for business continuity but does not estimate the actual time needed to fix an issue like a failed drive.

Recovery Point Objective (RPO) indicates the maximum acceptable amount of data loss measured in time before a failure occurs, focusing on data backup and recovery rather than repair time. RPO is concerned with how much data can be lost before impacting business operations, making it irrelevant to estimating fix times for server issues.
