ISC2 CC Practice Question: Business Continuity, Disaster Recovery, and Incident Response
An organization determines that its critical financial application has a maximum tolerable downtime (MTD) of 8 hours. The recovery time objective (RTO) is set to 6 hours, and the work recovery time (WRT) is 2 hours. If the application is restored from backup in 5 hours, but additional configuration takes 3 hours, what is the total downtime, and is the MTD met?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Total downtime 8 hours, MTD met
Total downtime = restoration (5 hours) + configuration (3 hours) = 8 hours, which equals MTD of 8 hours. So MTD is met (equal to MTD is acceptable).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Total downtime 10 hours, MTD exceeded
Why it's wrong here
Total is 8 hours, not 10.
- ✓
Total downtime 8 hours, MTD met
Why this is correct
The total downtime is calculated by summing the 5 hours required to restore the application from backup and the 3 hours for additional configuration, equalling 8 hours. This 8-hour total downtime precisely meets the Maximum Tolerable Downtime (MTD) of 8 hours specified in the scenario. Consequently, the MTD constraint is satisfied.
- ✗
Total downtime 8 hours, MTD exceeded
Why it's wrong here
MTD is 8 hours, so not exceeded.
- ✗
Total downtime 5 hours, MTD met
Why it's wrong here
Total downtime includes WRT, which is 3 hours, so total is 8 hours.
