AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

A company runs a production MySQL database on a single-AZ Amazon RDS instance in us-east-1a. Compliance now requires that the database experience no more than 2 minutes of unavailability if the Availability Zone hosting the primary instance fails. Operations staff must not perform any manual actions during a failover, and the solution should follow AWS best practices while minimizing operational overhead. Which change will meet these requirements?

  • Schedule frequent automated snapshots and restore the latest snapshot into another Availability Zone when a failure is detected.

  • Migrate the database to two self-managed MySQL EC2 instances in separate Availability Zones behind Amazon RDS Proxy to handle automatic failover.

  • Create an in-region MySQL read replica in another Availability Zone and configure Amazon RDS to promote it if the primary instance fails.

  • Modify the DB instance to enable Multi-AZ deployment so Amazon RDS creates a synchronous standby in a different Availability Zone that can automatically assume the primary role on failure.
