In Disaster Recovery Planning, which term refers to the maximum acceptable…

Concept: In Disaster Recovery Planning, RPO (Recovery Point Objective) is the maximum tolerable data loss, expressed as a time interval measured back from the moment of disruption, while RTO (Recovery Time Objective) is the maximum tolerable downtime for restoring service.

Application: The question asks for the term meaning “maximum acceptable data loss measured in terms of time.” This description is the definition of RPO: it specifies how far back in time the last valid recovery point must be, i.e., how much data the organization can afford to lose.

Cross-check: Contrasting the remaining terms confirms the choice:

• RTO measures allowable downtime (how quickly service must be restored), not data loss.

• MTTF (Mean Time To Failure) is a reliability metric — average operating time before a failure — unrelated to data-loss tolerance.

• DRP is the recovery plan/process itself, not a quantitative metric.

• BCP (Business Continuity Planning) is the broader continuity framework, not a data-loss measure.

Result: Only RPO defines the maximum acceptable data loss in time, so RPO is correct.
