Selected Answer: D

By modifying the DB instance to a Multi-AZ deployment, Amazon RDS automatically creates a standby replica of the primary database in a different Availability Zone, providing synchronous replication and automatic failover in case of a database failure. This ensures high availability and minimal downtime for the applications using the database.
