Git Foundations Quiz

Review

1. Where does a newly created, unstaged file exist?

   An unstaged file exists in the working tree but is not yet recorded in the index or a commit.
2. What does `git add README.md` primarily update?

   git add updates the index with the selected path’s current content.
3. What does `git diff --cached` compare?

   The cached form compares the index with HEAD, showing what is staged relative to the current commit.
4. What project state does a normal commit record?

   The commit’s tree is based on the content represented by the index.
5. Immediately after `git init -b main`, before the first commit, what does HEAD normally name?

   HEAD normally points symbolically to main even though that branch has no commit yet.
6. Which command directly inspects the commit referenced by HEAD?

   git show can display a revision such as HEAD and its associated commit information.
7. After a successful commit with no further changes, what should `git status --short` report?

   With the working tree and index matching the current commit, short status output is empty.
8. Which sequence best describes the core snapshot workflow taught here?

   The lesson models staging as moving selected working-tree content into the index, followed by commit creation from the index and subsequent history inspection.
