Match each business continuity concept on the left with the operational description on the right that best defines its role in disaster recovery planning.
- Work Recovery Time (WRT)The period needed for business operations testing, data validation, and process reintegration after technical systems are restored.
- Maximum Tolerable Downtime (MTD)The absolute maximum time a critical business function can remain inactive before the enterprise suffers irreversible operational failure.
- Mean Time to Repair (MTTR)The average time required for technical engineers to diagnose, fix, and restore a failed system component to operation.
- Single Point of Failure (SPOF)An unredundant system element or critical dependency that, if disrupted, results in complete outage of a business function.
Answer
The correct pairings align each continuity metric with its precise operational boundary: Work Recovery Time matches the phase for post-restoration business testing; Maximum Tolerable Downtime matches the ultimate time limit before irreversible damage; Mean Time to Repair matches the technical fix duration; and Single Point of Failure matches a critical unredundant component.
Each business continuity concept directly matches its operational definition: Work Recovery Time focuses on business verification after technical recovery; Maximum Tolerable Downtime represents the upper time boundary before critical business collapse; Mean Time to Repair is the average technical restoration speed; and Single Point of Failure is an unredundant bottleneck that can halt an entire service.
