CPA · Question 13 · Area I: Information Systems

A company has a Recovery Point Objective (RPO) of 4 hours. They currently perform a full backup every Sunday at midnight and incremental backups every night at midnight. Is this backup strategy adequate to meet the RPO?

Answer options:

A.

Yes, because incremental backups capture daily changes.

B.

No, because data created between midnight and 8 PM the next day would be lost if a failure occurs.

C.

Yes, provided the Recovery Time Objective (RTO) is also 4 hours.

D.

No, they must use differential backups instead of incremental.

How to approach this question

Compare the backup frequency (24 hours) with the RPO (4 hours).

Full Answer

B.No, because data created between midnight and 8 PM the next day would be lost if a failure occurs.✓ Correct
No, because data created between midnight and 8 PM the next day would be lost if a failure occurs.
RPO defines the maximum age of files that an organization must recover from backup storage for normal operations to resume. A 24-hour backup frequency cannot satisfy a 4-hour RPO; backups would need to occur at least every 4 hours.

Common mistakes

Confusing RPO (data loss) with RTO (downtime).
