CV0-004 Practice Question: Designing a disaster recovery plan for its cloud…
A company is designing a disaster recovery plan for its cloud infrastructure. The primary site is in US-East, and the DR site is in US-West. The RPO is 15 minutes, and the RTO is 2 hours. Which replication strategy best meets these requirements at the lowest cost?
⚠ Common exam trap
CompTIA often tests the misconception that synchronous replication is always better for DR, but the trap here is that the 15-minute RPO allows asynchronous replication, which is far more cost-effective across long distances than the expensive low-latency links required for synchronous replication.
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 from primary to DR
Asynchronous replication sends data changes from the primary site to the DR site with minimal delay, typically within seconds to minutes, which meets the 15-minute RPO. It does not require the low-latency link that synchronous replication demands, making it more cost-effective for geographically separated sites. The 2-hour RTO is achievable because the DR site can be activated quickly from the replicated data, without the overhead 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.
- ✗
Scheduled nightly backups to DR
Why it's wrong here
Nightly backups do not meet 15-minute RPO.
- ✓
Asynchronous replication from primary to DR
Why this is correct
Asynchronous replication achieves near-real-time RPO with lower cost and bandwidth requirements.
- ✗
Synchronous replication between sites
Why it's wrong here
Synchronous replication is costlier and may have performance impact over long distances.
- ✗
No replication; manual failover
Why it's wrong here
No replication results in significant data loss, exceeding the RPO.
