CV0-004 Practice Question: Is designing a disaster recovery plan for a…
A cloud engineer is designing a disaster recovery plan for a critical application. The application requires a Recovery Time Objective (RTO) of 15 minutes and a Recovery Point Objective (RPO) of 1 hour. Which replication strategy should be used?
⚠ Common exam trap
CompTIA often tests the misconception that synchronous replication is always the best choice for disaster recovery, but the trap here is that synchronous replication over long distances introduces unacceptable latency, making it unsuitable for applications with strict performance requirements, while asynchronous replication with appropriate snapshot intervals can meet moderate RPO/RTO goals without performance degradation.
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
✓
Asynchronous replication with snapshots every 30 minutes.
Asynchronous replication with snapshots every 30 minutes meets the RPO of 1 hour because data loss is limited to at most 30 minutes of changes, which is within the 1-hour window. The RTO of 15 minutes is achievable because the replicated data is readily available in the secondary region, allowing for rapid failover without the delay of restoring from backups.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Asynchronous replication with snapshots every 30 minutes.
Why this is correct
Snapshots every 30 minutes meet RPO of 1 hour; RTO achieved by failover.
- ✗
Daily backups stored in a different region.
Why it's wrong here
RPO of 24 hours does not meet 1 hour requirement.
- ✗
No replication; rely on infrastructure rebuild.
Why it's wrong here
Would not meet RTO or RPO.
- ✗
Synchronous replication between two regions.
Why it's wrong here
Overkill for 1-hour RPO; high cost.
