A company is designing a disaster recovery strategy for a critical application. The application uses Amazon EC2 and Amazon RDS. The RPO is 15 minutes and the RTO is 4 hours. Cost must be minimized. Which DR strategy is MOST appropriate?

Answer options:

Backup and Restore

Pilot Light

Warm Standby

Multi-Site Active/Active

How to approach this question

Balance the moderate RTO (4 hours) with the requirement to minimize cost.

Full Answer

B.Pilot Light✓ Correct

Pilot Light

Pilot Light keeps critical core elements (like databases) running in the DR region, while compute resources are provisioned only during a disaster, balancing cost and RTO.

Common mistakes

Choosing Warm Standby, which is more expensive and exceeds the requirements.
