Developing Applications and Automating Workflows Using Cisco Platforms (DEVASC) — Question 378

Which command reverses the last commit without changing the index file or the working tree position?

Answer options

• A. git revert HEAD
• B. git reset --hard HEAD~3
• C. git reset --soft HEAD^
• D. git revert

Correct answer: C

Explanation

The command 'git reset --soft HEAD^' is correct because it undoes the last commit while leaving both the index and working directory unchanged. In contrast, 'git revert HEAD' creates a new commit that undoes the changes of the last commit, while 'git reset --hard HEAD~3' completely discards the last three commits along with any changes, and 'git revert' without specifying a commit defaults to the last commit, which is not the same as the correct answer.
