ISC2 CC Practice Question: Business Continuity, Disaster Recovery, and Incident Response
A company’s disaster recovery plan specifies an RTO of 4 hours and an RPO of 1 hour for its critical database. The database is backed up every hour using incremental backups. After a catastrophic failure, restoration takes 3 hours, but the database must be rolled forward using transaction logs. The total time to make the database fully operational is 5 hours. Which statement is correct?
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
✓
RTO is exceeded but RPO is likely met
The RTO was exceeded (5 hours > 4 hours), but the RPO may still be met if the last backup was within 1 hour; the scenario does not indicate data loss beyond 1 hour.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Both RTO and RPO are exceeded
Why it's wrong here
RPO is likely met, so only RTO is exceeded.
- ✗
RPO is exceeded but RTO is met
Why it's wrong here
RTO is not met; RPO may be met.
- ✗
Both RTO and RPO are met
Why it's wrong here
RTO is not met because total time is 5 hours, exceeding 4 hours.
- ✓
RTO is exceeded but RPO is likely met
Why this is correct
Total recovery took 5 hours > RTO 4 hours; RPO is likely met because the backup was within 1 hour.
