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
