DevOps Interview DropAdvanced TierScenario+50 XP on read

Your organization wants production deployments to be reproducible six months later. How does Git help?

Core Summary

Git pins the source exactly and that's all it pins. Real reproducibility also needs locked dependencies, versioned infrastructure, immutable artifacts, and a stored record linking a deployment to its digest, plus keeping the actual artifact, because rebuilding it later is rarely byte-identical.

Hints

Hint 1: A commit SHA is a content hash of the whole tree

Hint 2: Same source does not mean same build

Hint 3: Keeping the artifact beats rebuilding it
