# Professional-Cloud-Database-Engineer — Question 426

**Type:** multiple_choice
**Topics:** topic_1

## Question

During an internal audit, you realized that one of your Cloud SQL for MySQL instances does not have high availability (HA) enabled. You want to follow Google-recommended practices to enable HA on your existing instance. What should you do?

## Correct Answer

_See scenario._

## Explanation

Selected Answer: C
A and B are obviously wrong, but it's still a bit confusing with the last two:
C - `gcloud instances patch` is not complete, it should be `gcloud sql instances patch`, so I would consider it to be wrong, if not the D - you can't edit your instance (i.e. enable HA) when it's shut down, you can only do it when instance is running, and then it will restart.
So I'll go for C
