CompTIA Linux+ XK0-006 (V8) Practice Question

The correct answer is the sequence that first updates the local main branch, then switches to the feature branch, and finally uses git rebase. The git rebase command is specifically designed to rewrite history by replaying commits from one branch on top of another, which results in a clean, linear history. This avoids the creation of an extra merge commit.

The sequence using git merge main would also integrate the changes, but it would do so by creating a merge commit, which preserves the forked history rather than creating the required linear one.

The sequence that involves git merge dev-feature while on the main branch is incorrect because it merges the feature into main, which is the opposite of the stated goal.

The sequence that begins with git rebase main before updating the local main branch is incorrect because the developer would be rebasing their work on a stale version of the main branch, not the latest version containing the critical fixes.
