A cloud administrator is looking at business requirements that specify the data available at the disaster recovery site must not be more than 24 hours old. Which of the following metrics correctly…

RTO (Recovery Time Objective) defines the maximum allowable time within which systems and data must be restored and accessible after a disruption, directly governing how current data must be at the DR site. A 24-hour RTO stipulates that the recovery site must be operational with data no older than 24 hours, establishing the boundary for replication and restoration schedules.

MTBF (Mean Time Between Failures) is a reliability metric measuring average operational time between failure events and has no bearing on data currency or recovery time targets.

MTTR (Mean Time To Repair) measures the average duration needed to restore a failed component to service and does not address the acceptable age of data at a recovery site.

RPO (Recovery Point Objective) addresses the maximum tolerable data loss expressed as a point in time, but the specific business constraint here - defining how old data can be at the DR site - is governed by the RTO metric in this scenario.
