CV0-004 Operations and Support Practice Question
A company is migrating on-premises workloads to a public cloud. The disaster recovery plan requires an RTO of 15 minutes and an RPO of 5 minutes. Which replication strategy should be used for a critical database?
⚠ Common exam trap
CV0-004 often tests RTO/RPO requirements and candidates may underestimate the frequency needed for backups, choosing snapshot intervals that are too long, thus failing to meet the RPO.
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
✓
Continuous replication to a standby instance in another region
Continuous replication to a standby instance in another region provides an RPO of near-zero (often seconds) and an RTO of minutes, as the standby can be promoted quickly. This meets the required RPO of 5 minutes and RTO of 15 minutes. Continuous replication ensures that data changes are replicated asynchronously or synchronously, depending on configuration, minimizing data loss.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Weekly full backups with daily incrementals stored in the same region
Why it's wrong here
Daily incrementals give an RPO of up to 24 hours and same-region storage offers no protection against a regional outage, so both targets fail. This pattern suits non-critical data where day-old recovery and local failures are acceptable.
- ✓
Continuous replication to a standby instance in another region
Why this is correct
Continuous replication ships every transaction to a standby in another region, giving an RPO of seconds and enabling failover well inside the 15-minute RTO. Snapshot or scheduled replication cannot meet a 5-minute RPO, since data written between intervals would be lost.
- ✗
Scheduled snapshots every hour with cross-region copy
Why it's wrong here
Hourly snapshots leave up to 60 minutes of data loss, breaching the 5-minute RPO, and snapshot restoration cannot reliably meet a 15-minute RTO. Hourly cross-region copies suit workloads with an RPO measured in hours, not minutes.
- ✗
Daily snapshots replicated cross-region
Why it's wrong here
Daily snapshots leave up to 24 hours of data loss, far exceeding the 5-minute RPO, and restoring a snapshot typically takes longer than the 15-minute RTO. Snapshots suit workloads tolerating hours of loss; continuous asynchronous replication is required here.
