Microsoft DevOps Engineer Expert AZ-400 Practice Question

A build pipeline that runs on Microsoft-hosted Linux agents restores about 300 MB of Maven dependencies from the public Maven Central repository on every execution. The team complains about long queue-to-publish times and the organization wants to reduce egress traffic charges. You must implement a change that

  • shortens the pipeline run time,
  • minimizes repeated network downloads,
  • automatically refreshes the stored files when the project's pom.xml changes,
  • requires no manual maintenance of the agent machines. Which action should you take?

  • Add a Cache@2 task that stores the local Maven repository using a key based on the SHA-1 hash of pom.xml.

  • Publish the .m2 directory as a pipeline artifact in the first stage and download it in later stages of every run.

  • Switch the pipeline to use the ubuntu-latest image, which includes more pre-installed build tools and caches.

  • Commit the entire .m2 directory to the Git repository using Git LFS so agents can clone the dependencies.
