A security administrator is documenting high-availability and business continuity metrics for an organization's core infrastructure. Match each availability metric on the left with its corresponding description on the right.
- Recovery Time Objective (RTO)The maximum targeted duration of outage time allowed to restore a system back to service.
- Recovery Point Objective (RPO)The maximum acceptable amount of data loss measured in time prior to an outage.
- Mean Time Between Failures (MTBF)The average expected operational time between unexpected system breakdown events.
- Mean Time to Repair (MTTR)The average duration required to troubleshoot, repair, and fully restore a failed system component.
Answer
Recovery Time Objective (RTO) matches the maximum targeted duration to restore a system; Recovery Point Objective (RPO) matches the maximum acceptable amount of data loss measured in time; Mean Time Between Failures (MTBF) matches the average expected operational time between breakdowns; Mean Time to Repair (MTTR) matches the average duration required to troubleshoot and repair a failed component.
Recovery Time Objective (RTO) represents the target time to bring systems back online. Recovery Point Objective (RPO) defines maximum tolerated data loss measured in time. Mean Time Between Failures (MTBF) measures system component reliability and expected operational runtime between crashes. Mean Time to Repair (MTTR) quantifies the average duration needed to repair and restore a failed item.
