Which metric defines the maximum acceptable downtime for an IT service during a disruption?

• A. Recovery Time Objective
• B. Recovery Point Objective
• C. Mean Time To Repair
• D. Uptime

Answer: (A)

The maximum acceptable downtime during a disruption is defined by the Recovery Time Objective. It sets the time window within which the IT service must be restored after an outage to prevent unacceptable business impact, guiding how you design and implement recovery strategies (like failover, backups, and automation) to meet that target. Recovery Point Objective covers how much data loss is tolerable, expressed as the age of the data that can be lost; Mean Time To Repair is the average time to fix a fault, an operational metric about repair speed; and uptime describes how often a service is available, but does not specify the allowed downtime duration.
