CMLBF

DMTTR

Show Suggested Answer

Suggested Answer: D

The expected time to recover or repair from a system from a failure is defined as MTTR (mean time to recovery or mean time to repair). MTTR is the average time it takes to restore a system or product to its normal operation after a failure. MTTR includes the time spent on detecting, diagnosing, and fixing the problem. MTTR is an important metric for measuring the reliability and availability of a system or product, as well as the efficiency and effectiveness of the incident management process. A lower MTTR indicates a faster and more reliable recovery or repair process.

MTBF is more about uptime, not recovery.

MCBF sounds familiar, but I don't think it's the answer here.

D) MTTR, the answer that keeps on ticking (or not ticking, in this case).

Hmm, MTTR... Sounds like the amount of time I spend repairing my car after it breaks down. Relatable!

MTTR, of course! How else would we know how long it takes to get the system back up and running?

I’m a bit confused because I thought MCBF was related to failures as well. But I guess it’s not the right one for recovery time?
