A developer accidentally committed a file containing a database password to a Git repository. The password is now in the commit history. The team wants to remove the password from the repository history entirely. They also use Git LFS for large files. What should you do?

Use 'git rm' to delete the file and commit the deletion.

Use Git LFS to purge the file from the LFS store.

Use 'git filter-repo' to remove the file from history and force-push the rewritten history.

Use 'git revert' on the commit that added the file.

A developer accidentally deleted a file from a feature branch and committed the deletion. The file was last modified in a commit on the main branch. The developer wants to recover the file content from the main branch without reverting the entire feature branch. What should the developer do?

Use git revert HEAD to undo the deletion commit.

Use git cherry-pick main to apply the main branch commit to the feature branch.

Use git checkout main -- path/to/file to restore the file from the main branch.

Use git reset --hard main to reset the feature branch to the main branch.

A team is using git-fat to manage large files in a Git repository. What is the primary purpose of git-fat?

To compress large files before storing them in Git

To replace large files with placeholder files and store the actual content in a separate backend

To split a large repository into multiple smaller repositories
