CV0-004 Practice Question: A cloud architect is designing a multi-tier…
A cloud architect is designing a multi-tier application that must meet a recovery time objective (RTO) of 15 minutes and a recovery point objective (RPO) of 1 hour. Which disaster recovery strategy is MOST cost-effective while meeting these requirements?
⚠ Common exam trap
CompTIA often tests the distinction between pilot light and warm standby, where candidates mistakenly believe pilot light can achieve a 15-minute RTO because it has database replication, but they overlook the time needed to provision and configure compute resources, which pushes the RTO beyond the requirement.
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
✓
Warm standby with database replication
Warm standby with database replication is the most cost-effective strategy that meets an RTO of 15 minutes and an RPO of 1 hour. It maintains a scaled-down but fully functional copy of the production environment in another region, with synchronous or asynchronous database replication ensuring data loss is within the 1-hour RPO. Failover can be automated to achieve the 15-minute RTO without the expense of running full production capacity in the standby region.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Backup and restore from object storage
Why it's wrong here
RTO likely exceeds 15 minutes.
- ✓
Warm standby with database replication
Why this is correct
Meets RTO and RPO cost-effectively.
- ✗
Pilot light with database replication
Why it's wrong here
May not meet 15-minute RTO due to provisioning time.
- ✗
Active-active across two regions
Why it's wrong here
Costs more than necessary.
