Maximum Tolerable Downtime (MTD) is comprised of which two metrics?

Maximum Tolerable Downtime (MTD) is comprised of which two metrics?

A.
Recovery Point Objective (RPO) and Work Recovery Time (WRT)

B.
Recovery Point Objective (RPO) and Mean Time to Repair (MTTR)

C.
Recovery Time Objective (RTO) and Work Recovery Time (WRT)

D.
Recovery Time Objective (RTO) and Mean Time to Repair (MTTR)

Explanation:
Answer C is correct; The Recovery Time Objective (RTO, the time it takes bring a failed system back online) and Work Recovery Time (WRT, the time required to configure a failed system) are used to calculate the Maximum Tolerable Downtime. RTO WRT MTD.

Incorrect Answers and Explanations: A, B, and D: Answers A, B, and D are incorrect. Maximum Tolerable Downtime does not directly use Recovery Point Objective or Mean Time to Repair as metrics.
