Your team has created an application that is hosted on a Google Kubernetes Engine (GKE) cluster. You need to connect the application to a legacy REST service that is deployed in two GKE clusters in two different regions. You want to connect your application to the target service in a way that is resilient. You also want to be able to run health checks on the legacy service on a separate port. How should you set up the connection? (Choose two.)

• A.Use Traffic Director with a sidecar proxy to connect the application to the service.
• B.Use a proxyless Traffic Director configuration to connect the application to the service.
• C.Configure the legacy service's firewall to allow health checks originating from the proxy.
• D.Configure the legacy service's firewall to allow health checks originating from the application.
• E.Configure the legacy service's firewall to allow health checks originating from the Traffic Director control plane.

Your company's development teams want to use Cloud Build in their projects to build and push Docker images to Container Registry. The operations team requires all Docker images to be published to a centralized, securely managed Docker registry that the operations team manages.
What should you do?

• A.Use Container Registry to create a registry in each development team's project. Configure the Cloud Build build to push the Docker image to the project's registry. Grant the operations team access to each development team's registry.
• B.Create a separate project for the operations team that has Container Registry configured. Assign appropriate permissions to the Cloud Build service account in each developer team's project to allow access to the operation team's registry.
• C.Create a separate project for the operations team that has Container Registry configured. Create a Service Account for each development team and assign the appropriate permissions to allow it access to the operations team's registry. Store the service account key file in the source code repository and use it to authenticate against the operations team's registry.
• D.Create a separate project for the operations team that has the open source Docker Registry deployed on a Compute Engine virtual machine instance. Create a username and password for each development team.
  Store the username and password in the source code repository and use it to authenticate against the operations team's Docker registry.

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.
