Answers
D.
Shut down your existing Cloud SQL for MySQL instance, and enable HA.
Suggested answer: C

Explanation:

Creating a new instance and migrating data can be time-consuming and disruptive to your application's availability. Shutting down the existing instance is not a recommended approach, as it will cause downtime for your application.

The recommended approach is to use the gcloud instances patch command to enable high availability on your existing Cloud SQL for MySQL instance. This command updates the instance's configuration to enable the failover replica, configure it, and enable automatic failover.

By following this approach, you can ensure minimal downtime, and your application can continue to operate during the process.
