What is the maximum acceptable amount of data loss measured in time?

• A. RTO
• B. RPO
• C. MTTR
• D. MTBF

Answer: (B)

The concept being tested is Recovery Point Objective. It defines how much data an organization can afford to lose in a disaster, expressed as a time window. For example, if backups happen every 15 minutes, the RPO is 15 minutes—the maximum amount of data you could lose corresponds to those 15 minutes since the last backup. This is different from the Recovery Time Objective, which focuses on how long it takes to restore services after a disruption, not how much data is lost. MTTR is about the repair time after a failure, and MTBF is about the average time between failures. So the maximum acceptable data loss measured in time aligns with the Recovery Point Objective.
