CV0-004 Practice Question: A cloud architect is planning a disaster recovery…
A cloud architect is planning a disaster recovery (DR) strategy for a mission-critical application. The RTO must be under 1 hour and RPO under 15 minutes. The primary site is in a different region. Which DR pattern meets these requirements?
⚠ Common exam trap
CompTIA often tests the misconception that 'pilot light' is only for low-criticality apps, but the trap here is that candidates confuse it with cold standby, failing to recognize that pilot light's pre-provisioned core and continuous replication can meet strict RTO/RPO targets without the cost of full active-active.
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
✓
Pilot light
The pilot light pattern meets the RTO under 1 hour and RPO under 15 minutes because it keeps a minimal core set of services (e.g., database replicating via asynchronous replication) running in the DR region, allowing rapid scale-up of the full application stack during failover. This pattern balances cost and recovery speed, as the replicated data ensures an RPO of seconds to minutes, and the pre-provisioned core infrastructure enables failover within minutes, satisfying the strict RTO.
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
Why it's wrong here
Backup and restore typically has RTO of hours to days.
- ✗
Cold standby
Why it's wrong here
Cold standby requires provisioning resources from scratch, leading to long RTO.
- ✓
Pilot light
Why this is correct
Pilot light keeps minimal resources running and can scale up quickly to meet RTO/RPO.
- ✗
Multi-site active-active
Why it's wrong here
Active-active offers near-zero RTO but is more expensive and may not be necessary.
