Your App Engine standard configuration is as follows:

service: production

instance_class: B1

You want to limit the application to 5 instances. Which code snippet should you include in your configuration?

A. manual_scaling:instances: 5min_pending_latency: 30ms

B. manual_scaling:max_instances: 5idle_timeout: 10m

C. basic_scaling:instances: 5min_pending_latency: 30ms

D. basic_scaling:max_instances: 5idle_timeout: 10m

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 have an application deployed in production. When a new version is deployed, some issues don't arise until the application receives traffic from users in production. You want to reduce both the impact and the number of users affected.

Which deployment strategy should you use?

A. Blue/green deployment

B. Canary deployment

C. Rolling deployment

D. Recreate deployment
