Which metric defines the maximum allowable downtime after a disruption?

Explanation:
RTO defines the maximum allowable downtime after a disruption. It specifies how quickly IT services and processes must be restored to prevent unacceptable business impact, guiding the selection of recovery strategies like rapid failover, backups, or hot standby environments. RPO, by contrast, deals with how much data can be lost, not how long systems can be down. MTBF measures the reliability of components by the average time between failures, not the allowable downtime after an incident. An SLA is a contractual agreement that can include uptime targets, but the specific metric for downtime duration after disruption is the RTO.
