CV0-004 Operations and Support Practice Question
A company is designing a disaster recovery plan for a critical database that requires a recovery point objective (RPO) of 1 minute and a recovery time objective (RTO) of 15 minutes. The database runs on a cloud virtual machine. Which backup strategy should the administrator implement to meet these requirements?
⚠ Common exam trap
CV0-004 often tests the difference between RPO and RTO, and candidates may choose snapshot-based solutions thinking they are sufficient, but snapshots typically have higher RPO.

Correct answer & explanation
✓
Implement continuous replication to a standby instance in a different region.
Continuous replication to a standby instance in a different region provides an RPO of near-zero (often seconds) and an RTO of minutes, as the standby can be promoted quickly. This meets the 1-minute RPO and 15-minute RTO requirements. It also provides cross-region disaster recovery, which is essential for critical databases.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Take daily snapshots and store them in the same region.
Why it's wrong here
Daily snapshots in the same region cannot deliver a one-minute RPO, since up to 24 hours of writes would be lost, and a regional outage would also destroy the copies. Snapshots suit low-churn workloads with relaxed RPOs, where periodic point-in-time recovery within a single region is acceptable.
- ✗
Perform weekly backups to tape and store offsite.
Why it's wrong here
Weekly tape backups leave up to seven days of data unprotected, so the one-minute RPO is unachievable regardless of restore speed. Tape remains valid for long-term archival retention or air-gapped offsite copies, where multi-day recovery points and lengthy restore windows are acceptable rather than business-critical.
- ✗
Use cross-region snapshot replication with hourly snapshots.
Why it's wrong here
Hourly snapshots leave up to 60 minutes of data loss, breaching the one-minute RPO regardless of cross-region replication. Snapshot replication suits workloads tolerating hour-scale recovery points, such as nightly batch systems or non-critical file shares, where a full hour of lost writes is acceptable.
- ✓
Implement continuous replication to a standby instance in a different region.
Why this is correct
Continuous replication to a standby instance in another region satisfies the one-minute RPO by shipping every transaction asynchronously, and meets the fifteen-minute RTO because the standby is already running and can be promoted immediately, avoiding restore-from-backup delays.
