Correct answer: Convert the DB instance to a Multi‑AZ deployment..
Why this is the answer
Converting the Amazon RDS DB instance to a Multi-AZ deployment is the correct solution because it provides high availability and automatic failover to a standby replica in another Availability Zone if the primary instance becomes unavailable. This failover typically completes in minutes, satisfying the recovery time objective (RTO) of under 5 minutes. A read replica improves read performance and can be promoted to a standalone DB instance, but it doesn't provide automatic failover for the primary instance. An AWS CloudFormation template helps automate deployment but doesn't inherently provide high availability for an existing instance. Frequent snapshots are good for data recovery but involve manual restoration, which would exceed the 5-minute RTO.
