Ed is working with functional units in his organization to document the maximum amount of time that they could be without a critical IT service during a disaster. What metric should he use to document this requirement?
A. RTO
B. RPO
C. MTTR
D. MTBF
Correct Answer: A
The recovery time objective (RTO) is the amount of time that the business can tolerate an outage during a disaster, making it our correct answer. The recovery point objective (RPO) is the amount of tolerable data loss, which is not what we are looking for here. The mean time to repair (MTTR) is the amount of time required to repair a damaged system, while the mean time between failures (MTBF) describes the frequency of failures, neither of which are correct answers.
