CV0-004 Operations and Support Practice Question
A company wants to implement a disaster recovery strategy with an RTO of 15 minutes and an RPO of 1 minute for a critical database. Which approach should be used?
⚠ Common exam trap
CV0-004 often tests the misconception that frequent snapshots can achieve a low RPO, but snapshots are point-in-time and cannot meet sub-minute RPO; candidates must recognize that continuous replication is required for very low RPO.

Correct answer & explanation
✓
Cross-region continuous replication with automatic failover
The requirement is an RTO of 15 minutes and an RPO of 1 minute. Cross-region continuous replication with automatic failover provides near-zero RPO (often seconds) and rapid RTO (minutes) by continuously replicating data and automatically promoting a standby in another region. This is the only option that can meet both the 1-minute RPO and 15-minute RTO.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Scheduled snapshots every hour
Why it's wrong here
Hourly snapshots leave up to 60 minutes of data loss, breaching the 1-minute RPO, and restoring a snapshot typically exceeds the 15-minute RTO. Scheduled snapshots suit workloads tolerating hour-scale recovery. Continuous replication or synchronous mirroring meets minute-level RPO with rapid failover.
- ✗
Daily snapshots copied to another region
Why it's wrong here
Daily replication to another region leaves up to 24 hours of data loss, violating the 1-minute RPO, even though regional copies aid site-loss recovery. It suits workloads with day-scale recovery tolerances. Continuous cross-region replication or synchronous mirroring achieves the required minute-level RPO and 15-minute RTO.
- ✗
Weekly full backups to tape stored offsite
Why it's wrong here
Weekly tape backups permit up to seven days of data loss, far beyond the 1-minute RPO, and tape retrieval plus restore cannot complete within 15 minutes. Offsite tape suits long-term retention and archival compliance. Continuous replication with automated failover satisfies both the RPO and RTO targets.
- ✓
Cross-region continuous replication with automatic failover
Why this is correct
Continuous cross-region replication keeps a standby copy within seconds of the primary, satisfying the one-minute RPO, while automatic failover redirects traffic without manual intervention, meeting the fifteen-minute RTO. Neither scheduled snapshots nor single-region backups can achieve both targets.
