C. Use Stackdriver to capture and alert on logs, then ship them to your existing platform.

D. Migrate some traffic back to your old platform and perform AB testing on the two platforms concurrently.

Question 3Topic 1

You are planning to migrate a MySQL database to the managed Cloud SQL database for Google Cloud. You have Compute Engine virtual machine instances that will connect with this Cloud SQL instance. You do not want to whitelist IPs for the Compute Engine instances to be able to access Cloud SQL.
What should you do?

A. Enable private IP for the Cloud SQL instance.

B. Whitelist a project to access Cloud SQL, and add Compute Engine instances in the whitelisted project.

C. Create a role in Cloud SQL that allows access to the database from external instances, and assign the Compute Engine instances to that role.
