Brian recently determined the number of times that a system experienced a failure during the past year. In disaster recovery terms, what metric has he documented?

A. Mean Time Between Failures (MTBF)

B. Mean Time To Repair (MTTR)

C. Recovery Time Objective (RTO)

D. Recovery Point Objective (RPO)

Correct Answer: A

The recovery time objective (RTO) is the amount of time that the business can tolerate an outage during a disaster. That’s not quite what we’re looking for here, so it’s not the correct answer. The recovery point objective (RPO) is the amount of tolerable data loss. The RPO also isn’t what’s described in this question. The mean time to repair (MTTR) is the amount of time required to repair a damaged system, so we can eliminate that choice. That leaves us with the correct answer, the mean time between failures (MTBF) which describes the frequency of failures, or the amount of time between failures.
