AWS SAP-C02 · Question 08 · Domain 1.3: Reliable Architectures
A healthcare company is designing a disaster recovery strategy for a critical application. The application uses EC2 instances and an RDS SQL Server database. The business requires an RPO of 15 minutes and an RTO of 4 hours. The solution must be as cost-effective as possible. Which DR strategy should the architect choose?
Answer options:
Backup and Restore: Take hourly RDS snapshots and EC2 AMIs. Copy them to the DR region.
Pilot Light: Replicate the RDS database to the DR region. Keep EC2 instances stopped or use Auto Scaling with capacity 0.
Warm Standby: Run a scaled-down version of the application in the DR region.
Multi-Site Active-Active: Run full capacity in both regions.
