Henry’s organization has set their RTO to 12 hours. What does this mean?
Answer Options
Outages must be less than 6 hours long.
Recovery from outages should take less than 12 hours.
Outages longer than 12 hours will require fail over to a warm site.
SLAs for third-party services should specify a 12 hour MTBF.
Correct Answer: B
Explanation
A recovery time objective, or RTO, is set by organizations to describe how long restoring systems or services to normal function after a disruption can take. A 12-hour RTO means that recovery from outages should take less than 12 hours. Failing over to a warm site will typically take a while, meaning that starting to fail over after 12 hours will miss the RTO, and MTBF is the mean time between failures, not a recovery timeframe. Failing every 12 hours on average would be unacceptable for almost any technical service or system!
