• B.File a ticket with Cloud Support indicating that the application performs faster locally.
• C.Add logging commands to the application and use Stackdriver Logging to check where the latency problem occurs.
• D.Use Stackdriver Debugger Snapshots to look at a point-in-time execution of the application.

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.
• D.Create a CloudSQL instance on one project. Create Compute engine instances in a different project.
  Create a VPN between these two projects to allow internal access to CloudSQL.

You are working on a social media application. You plan to add a feature that allows users to upload images.
These images will be 2 MB - 1 GB in size. You want to minimize their infrastructure operations overhead for this feature.
What should you do?

• A.Change the application to accept images directly and store them in the database that stores other user information.
• B.Change the application to create signed URLs for Cloud Storage. Transfer these signed URLs to the client application to upload images to Cloud Storage.
• C.Set up a web server on GCP to accept user images and create a file store to keep uploaded files. Change the application to retrieve images from the file store.
• D.Create a separate bucket for each user in Cloud Storage. Assign a separate service account to allow write access on each bucket. Transfer service account credentials to the client application based on user information. The application uses this service account to upload images to Cloud Storage.
