Exam Preparation Quiz

Explanations for each answer:

• git log is correct. The git log command helps locate the SHA1 hash of the last commit on the deleted branch. It displays the commit history and allows you to identify the specific commit where the branch was before deletion.
• git checkout (SHA1) is correct. After identifying the commit hash with git log, the git checkout command with the SHA1 parameter moves your repository to the state of that specific commit, positioning you at the point where the branch existed. Note that there is also a shorthand command 'git checkout -b <branch> <hash>' that combines the checkout and the subsequent branch operation.
• git branch features/feature11 is correct. Once you've checked out the commit, this command creates a new branch with the same name as the deleted branch at the current commit position, effectively recovering the deleted branch with all its content.
• git restore (SHA1) is incorrect. The git restore command is used to restore files in the working tree from the index or another commit, not for recovering deleted branches. This command doesn't help establish a branch at a previous commit point.
• git stash is incorrect. The git stash command is used to temporarily store modified tracked files to save changes without committing. It doesn't help in recovering deleted branches as it doesn't interact with the branch structure of the repository.
