CV0-004 Practice Question: A cloud architect is designing a disaster…
A cloud architect is designing a disaster recovery plan for a critical application. The application runs on virtual machines in a public cloud. The recovery time objective (RTO) is 1 hour, and the recovery point objective (RPO) is 15 minutes. Which three strategies should the architect implement? (Select THREE).
⚠ Common exam trap
CompTIA Cloud+ often tests the distinction between replication strategies and recovery environments—candidates mistakenly think asynchronous replication alone meets RPO without considering that it must be paired with a standby site to achieve the RTO, or they overlook that daily snapshots are too infrequent for a 15-minute 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
✓
Implement active-passive failover with automated DNS.
Active-passive failover with automated DNS allows traffic to be redirected to a standby environment within minutes, meeting the 1-hour RTO. The passive site remains ready with pre-provisioned resources, and DNS propagation can be controlled via low TTL values to achieve rapid failover.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Implement active-passive failover with automated DNS.
Why this is correct
Correct. Automated DNS failover speeds up recovery, helping achieve the RTO.
- ✓
Use synchronous replication to a secondary region.
Why this is correct
Correct. Synchronous replication provides near-zero RPO, meeting the 15-minute requirement.
- ✗
Take daily snapshots of the VMs.
Why it's wrong here
Daily snapshots exceed the 15-minute RPO.
- ✗
Use asynchronous replication with a 10-minute lag.
Why it's wrong here
Asynchronous replication may meet RPO but does not guarantee automated failover to meet RTO; it is less reliable than synchronous.
- ✓
Maintain a warm standby in another region.
Why this is correct
Correct. A warm standby can be activated quickly to meet the 1-hour RTO.
