Exam Professional Cloud Architect topic 1 question 145 discussion

Actual exam question from Google's Professional Cloud Architect
Question #: 145
Topic #: 1
[All Professional Cloud Architect Questions]

Your company has an application running as a Deployment in a Google Kubernetes Engine (GKE) cluster. You have separate clusters for development, staging, and production. You have discovered that the team is able to deploy a Docker image to the production cluster without first testing the deployment in development and then staging. You want to allow the team to have autonomy but want to prevent this from happening. You want a Google Cloud solution that can be implemented quickly with minimal effort. What should you do?

  • A. Configure a Kubernetes lifecycle hook to prevent the container from starting if it is not approved for usage in the given environment.
  • B. Implement a corporate policy to prevent teams from deploying Docker images to an environment unless the Docker image was tested in an earlier environment.
  • C. Configure binary authorization policies for the development, staging, and production clusters. Create attestations as part of the continuous integration pipeline.
  • D. Create a Kubernetes admissions controller to prevent the container from starting if it is not approved for usage in the given environment.

A good option for quickly implementing a solution to prevent deployments to the production cluster without first testing in development and staging would be to configure binary authorization policies for the development, staging, and production clusters. You can then create attestations as part of the continuous integration pipeline. Option C, "Configure binary authorization policies for the development, staging, and production clusters. Create attestations as part of the continuous integration pipeline," would be the correct choice for this scenario. Binary authorization is a feature of Google Kubernetes Engine that allows you to enforce policies on the images that are deployed to your clusters. By configuring binary authorization policies for the development, staging, and production clusters, you can ensure that only images that have been attested by an authorized entity are allowed to be deployed to those clusters. You can create the attestations as part of the continuous integration pipeline, which will allow you to verify that the image has been tested before it is deployed to the next environment.

Option A, "Configure a Kubernetes lifecycle hook to prevent the container from starting if it is not approved for usage in the given environment," would not be a good choice because it would not prevent the deployment of the container to the cluster in the first place. Option D, "Create a Kubernetes admissions controller to prevent the container from starting if it is not approved for usage in the given environment," would also not be a good choice because it would not prevent the deployment of the container to the cluster in the first place. Option B, "Implement a corporate policy to prevent teams from deploying Docker images to an environment unless the Docker image was tested in an earlier environment," would be a good option, but it would not be as effective as using binary authorization policies, as it would rely on the team following the policy rather than enforcing it automatically.

C is right.. Binary Authorization implements a policy model, where a policy is a set of rules that governs the deployment of container images. Rules in a policy provide specific criteria that an image must satisfy before it can be deployed. For more information about the Binary Authorization policy model and other concepts, see Key concepts.
