AWS Certified Solutions Architect Associate SAA-C03 Practice Question

An e-commerce company runs a production Amazon RDS for MySQL instance that uses Provisioned IOPS (io2) storage. To handle an upcoming flash-sale event, the database administrator plans to increase the Provisioned IOPS from 40,000 to 60,000 and chooses Apply immediately in the console. Which statement accurately describes what will happen after the modification is submitted?

  • The DB instance stays online; no downtime occurs, but I/O performance can be temporarily degraded while storage optimization completes.

  • Only PostgreSQL and Oracle support online IOPS changes; MySQL requires a maintenance window that causes downtime.

  • The DB instance becomes unavailable until the storage change finishes and the instance is automatically rebooted.

  • Provisioned IOPS cannot be changed in place; the administrator must restore from a snapshot configured with the new IOPS value.
