Microsoft DevOps Engineer Expert AZ-400 Practice Question

You need to define a branching and deployment strategy for a GitHub repository that hosts an enterprise-wide Node.js microservice. The requirements are:

  • The 'main' branch must always contain code that is ready to be promoted to production.
  • New work should be isolated without blocking other teams.
  • Code reviews and automated tests must run before the code is merged.
  • The repository's history should stay linear and easy to trace. Which approach satisfies these requirements and follows GitHub Flow principles?

  • Commit directly to 'main', tag a semantic version when ready, and trigger the release pipeline from the tag without using pull requests or CI checks.

  • Create environment branches named 'dev', 'stage', and 'prod'; merge pull requests sequentially between them to promote releases while allowing direct pushes to 'dev' for urgent fixes.

  • Create short-lived topic branches from 'main', open a pull request that requires at least one approving review and a passing CI workflow, then squash and merge the pull request back into 'main', triggering an automated deployment pipeline.

  • Maintain a persistent 'development' branch where all features are merged. Once a sprint ends, create a pull request from 'development' to 'main' and deploy after manual testing.
