SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
A company is migrating a critical application to AWS and needs to ensure business continuity. The application must be able to fail over to a different AWS Region with a Recovery Time Objective (RTO) of 15 minutes and a Recovery Point Objective (RPO) of 1 minute. Which strategy should the company use?

Correct answer & explanation
✓
Warm standby in another Region
Warm standby in another Region is the best strategy to achieve RTO of 15 minutes and RPO of 1 minute. A warm standby involves running a scaled-down version of the production environment in another Region, which can be quickly scaled up during failover. This approach allows for continuous data replication, typically with asynchronous replication that can achieve an RPO of 1 minute, and failover within minutes, meeting the 15-minute RTO. Multi-Region active-active with synchronous replication is often impractical across long distances due to latency and cost, and synchronous replication typically requires both Regions to be active, which is complex and not necessary for this requirement. Pilot light has longer RTO (typically 10-30 minutes or more) and backup and restore has much higher RTO and RPO.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Warm standby in another Region
Why this is correct
Warm standby can achieve RTO of 15 minutes and RPO of 1 minute by maintaining a scaled-down environment in another Region with continuous replication. Correct answer.
- ✗
Multi-Region active-active deployment with synchronous replication
Why it's wrong here
Multi-Region active-active with synchronous replication can meet the RPO of 1 minute but typically has higher complexity and cost, and synchronous replication across regions is limited by latency, making it less practical for this scenario. This approach is often used for zero RPO, but here RPO of 1 minute is acceptable.
- ✗
Pilot light in another Region
Why it's wrong here
Pilot light has a longer RTO (often 30+ minutes) as it requires provisioning resources and starting applications before failover, making it unsuitable for a 15-minute RTO.
- ✗
Backup and restore to another Region
Why it's wrong here
Backup and restore has high RTO (hours) and RPO (typically 24 hours or more due to backup schedule), far exceeding the requirements.
