DevOps Version Control & Git Workflows 3

Question 1

What is 'semantic versioning' (SemVer) and which format does it use?

Accepted Answer

A versioning scheme using MAJOR.MINOR.PATCH

Answer

Semantic versioning uses MAJOR.MINOR.PATCH where MAJOR breaks compatibility, MINOR adds features backward-compatibly, and PATCH fixes bugs.

Question 2

What is the purpose of a Git 'hook'?

Accepted Answer

A script that runs automatically before or after specific Git events

Answer

Git hooks are shell scripts placed in the .git/hooks directory that execute automatically at key points like pre-commit, post-merge, or pre-push.

Question 3

When using a monorepo, what is a common challenge teams face with Git?

Accepted Answer

Slower clone and fetch times due to the large repository size

Answer

Monorepos can become very large over time, causing slow clone, fetch, and checkout operations that require tools like Git LFS or sparse checkout to mitigate.

Question 4

What does 'git bisect' help a DevOps engineer do?

Accepted Answer

Identify which commit introduced a bug using binary search

Answer

'git bisect' performs a binary search through commit history, marking commits as good or bad until it pinpoints the exact commit that introduced a regression.

Question 5

Which practice ensures that configuration and infrastructure definitions are stored and versioned alongside application code?

Accepted Answer

GitOps

Answer

GitOps uses Git as the single source of truth for both application and infrastructure state, with automated reconciliation to apply declared configurations.
