A security enterprise architect is formalizing Business Impact Analysis (BIA) and Business Continuity Management (BCM) metrics for a multi-region cloud deployment. Match each continuity metric on the left with the operational description on the right that best defines its role in disaster recovery planning.
- Maximum Tolerable Downtime (MTD)The maximum allowable cumulative duration of system unavailability before the enterprise faces catastrophic financial or operational failure.
- Work Recovery Time (WRT)The operational period required after technical system restoration to complete data integrity audits, backlog processing, and verification before business function sign-off.
- Recovery Service Level (RSL)The minimum percentage of baseline processing throughput and functional capability required while operating on contingency infrastructure.
- Mean Time Between Failures (MTBF)The statistical metric measuring system component reliability by quantifying average operational uptime between unexpected failures.
Answer
Maximum Tolerable Downtime pairs with the maximum cumulative outage duration allowed before catastrophic failure. Work Recovery Time pairs with the post-restoration operational phase for data validation and business sign-off. Recovery Service Level pairs with the required percentage of processing capability during contingency mode. Mean Time Between Failures pairs with the average operational uptime between component failures.
Each continuity metric corresponds to a distinct phase or measurement of resilience: MTD defines the maximum overall downtime tolerance; WRT covers post-restoration operational validation; RSL establishes performance capacity expectations during failover; and MTBF measures overall system reliability.
