What is the primary purpose of access control in a source code repository?

To speed up the repository by caching frequently accessed files

To ensure only authorized users can view, modify, or delete code

To create backups of the repository on a regular schedule

To automatically merge branches without conflicts

Which of the following is a key benefit of using a version control system?

It automatically fixes coding errors and bugs in the source code

It provides a complete history of changes, enabling rollback to any previous version

It guarantees that code is always production-ready

It eliminates the need for code reviews and testing

A developer has made several commits to a feature branch. They realize that the last two commits contain sensitive information that should not be in the repository's history. They want to remove these commits from the history before pushing the branch to the remote. What is the most appropriate action?

Use 'git revert' to create new commits that undo the sensitive changes.

Use 'git commit --amend' to modify the last commit only.

Use 'git reset' to move the branch pointer back to the commit before the sensitive commits, then force push the branch.

Delete the local repository and clone the remote again, then reapply the changes.

In a Git hosting service like GitHub, what does a 'read-only' permission level typically allow a user to do?

Clone and view the repository, but not push changes

Push changes to the main branch

Manage user permissions for the repository

A company has a private Git repository containing proprietary code. They want to allow a contractor to view and clone the repository, but not push changes. What is the most appropriate access control configuration?

Grant the contractor write access to the repository.

Create a fork of the repository and grant the contractor access to the fork.

Grant the contractor read-only access to the repository.

Share the repository URL with the contractor and rely on the repository being private.
