DevOps Version Control & Git Workflows 1

Question 1

Which Git branching strategy uses long-lived branches named 'main', 'develop', 'release', and 'hotfix'?

Accepted Answer

Gitflow

Answer

Gitflow defines a strict branching model with dedicated branches for features, releases, and hotfixes alongside main and develop.

Question 2

What does the command 'git rebase -i HEAD~3' accomplish?

Accepted Answer

Interactively edits the last 3 commits

Answer

The '-i' flag enables interactive rebase, letting you squash, reorder, or edit the specified number of recent commits.

Question 3

In Trunk-Based Development, how often should developers integrate their changes into the main branch?

Accepted Answer

At least once per day

Answer

Trunk-Based Development requires developers to integrate to the main trunk at least daily to minimize merge conflicts and enable continuous integration.

Question 4

What is a 'fast-forward merge' in Git?

Accepted Answer

A merge where the branch pointer simply moves forward without creating a merge commit

Answer

A fast-forward merge occurs when the target branch has no new commits since the feature branch diverged, so Git just moves the pointer forward.

Question 5

Which Git command is used to temporarily save uncommitted changes without committing them?

Accepted Answer

git stash

Answer

'git stash' stores your working directory changes and staged snapshot so you can switch context and reapply later.
