A company is designing a disaster recovery (DR) strategy for their critical application. They require a Recovery Time Objective (RTO) of less than 15 minutes. They want to minimize costs but are willing to pay for necessary resources. Which TWO DR strategies would meet the RTO requirement? (Select TWO.)

Q: What mistakes do candidates make on this AWS SAA-C03 question?

Selecting Pilot Light, which usually takes tens of minutes to hours to scale up compute resources.

Answer options:

Backup and Restore

Pilot Light

Warm Standby

Multi-Site Active/Active

Cross-Region Snapshot Copy

How to approach this question

Evaluate DR strategies based on RTO. <15 mins requires infrastructure to be already running.

Full Answer

Warm Standby ensures a scaled-down version of the application is always running, allowing rapid scaling and failover (RTO in minutes). Multi-Site Active/Active has zero downtime (RTO near zero). Pilot Light and Backup/Restore take too long.

Common mistakes

Selecting Pilot Light, which usually takes tens of minutes to hours to scale up compute resources.
