Microsoft DevOps Engineer Expert AZ-400 Practice Question

Your team's Azure Repos Git repository contains several years of history in which artists committed *.png and *.fbx game-asset files that are typically 200-400 MB each. Cloning the repo now takes more than 30 minutes and CI pipelines routinely exceed the 5 GB checkout limit. You must migrate the existing objects to Git Large File Storage (LFS) so that only lightweight pointer files remain in regular Git history, while preserving commit metadata. Which approach meets the goal with the least manual effort?

  • Run git lfs track ".png" ".fbx", commit the updated .gitattributes file, and push the branch normally.

  • Enable the Large File Checkout option in Azure Repos and perform git gc to prune existing large blobs.

  • Use git filter-branch with a tree-filter that calls git lfs track for each commit, then push the result to origin.

  • Install Git LFS locally, then execute git lfs migrate import --include=".png,.fbx" --include-ref=refs/heads/*; afterward push the rewritten history with git push --force-with-lease --all && git push --force-with-lease --tags.
