In organizational resilience and business continuity planning, theRecovery Time Objective (RTO)is a core metric used to determine the acceptable downtime for each business function.
EPI defines RTO as the:
“Targeted duration within which disrupted services or processes must be restored to a minimum acceptable operational level after a disaster.”
Key points:
Timeframe for RecoveryThe RTO identifieshow quicklya facility, system, or service must be restored before the outage causes unacceptable consequences.
Minimum Service CapacityThe RTO refers to restoring operationsat a minimum acceptable level, not full normal operations.
Business Impact Analysis (BIA) OutputRTO is derived during BIA where criticality and dependencies of business processes are assessed and prioritized.
Prioritization of ResourcesRTO informs disaster recovery planning, resource allocation, and restoration sequencing.
Therefore, the correct definition matches:
D — “The prioritized timeframes for resuming disrupted activities at a specified minimum acceptable capacity.”
Why the other options are incorrect:
Adescribes the MTPD (Maximum Tolerable Period of Disruption).
Bdescribes elements of the Minimum Business Continuity Objective (MBCO).
Cdescribes the Recovery Point Objective (RPO).

RTO is linked to minimum acceptable capability after recovery.
RTO is determined through BIA.
