Can I initiate a "forced failover" for my MySQL Multi-AZ DB Instance deployment?
A. Only in certain regions
B. Only in VPC
C. Yes
D. No
Correct Answer: A
Explanation/Reference:
Explanation:
If your DB instance is a Multi-AZ deployment, you can force a failover from one availability zone to another when you select the Reboot option. When you force a failover of your DB instance, Amazon RDS automatically switches to a standby replica in another Availability Zone and updates the DNS record for the DB instance to point to the standby DB instance. As a result, you will need to clean up and re-establish any existing connections to your DB instance. Reboot with failover is beneficial when you want to simulate a failure of a DB instance for testing, or restore operations to the original AZ after a failover occurs.

Q: Can I initiate a “forced failover” for my Multi-AZ DB instance deployment?
Amazon RDS will automatically fail over without user intervention under a variety of failure conditions. In addition, Amazon RDS provides an option to initiate a failover when rebooting your instance. You can access this feature via the AWS Management Console or when using the RebootDBInstance API call.
