[All Professional Cloud Architect Questions]

You are building a continuous deployment pipeline for a project stored in a Git source repository and want to ensure that code changes can be verified before deploying to production. What should you do?

  • A. Use Spinnaker to deploy builds to production using the red/black deployment strategy so that changes can easily be rolled back.
  • B. Use Spinnaker to deploy builds to production and run tests on production deployments.
  • C. Use Jenkins to build the staging branches and the master branch. Build and deploy changes to production for 10% of users before doing a complete rollout.
  • D. Use Jenkins to monitor tags in the repository. Deploy staging tags to a staging environment for testing. After testing, tag the repository for production and deploy that to the production environment.

I believe the best answer is D, because the tagging is a best practice that is recommended on Jenkins/Spinnaker to deploy the right code and prevent accidentally (or intentionally) push of wrong code to production environments. See https://stackify.com/continuous-delivery-git-jenkins/

I don't think it was a good idea when new edtion be created and directly deploy to the production ENV without any testing stage even using Canary deployment.

I choose D as we want to ensure that code changes can be verified BEFORE deploying to production. Option C suggests that we build and deploy changes to production for 10% of users.

Vote D. C is canary deploy. But the sentence in question has no word to mean "tested by a small number of users"
