A Git Subtree allows you to keep a copy of an external repository in a subdirectory, treating it as a __________ project.
- separate
- nested
- linked
- subtree
The correct answer is subtree. Git subtree is a merging strategy that allows you to insert the contents of a repository into another one, but unlike submodules, the external repository becomes part of the history of the main repository. It is treated as a subtree within the main project.
The git _______ command creates a new commit that undoes all of the changes made in a specified commit.
- revert
- reset
- undo
- backout
The correct option is revert. The git revert command is used to create a new commit that undoes the changes made in a previous commit, effectively reverting the repository's state to a previous point in time.
A git _______ is used to combine multiple commits into a single commit for a cleaner history.
- merge
- squash
- combine
- join
The correct option is squash. The git squash command is used during interactive rebase to combine multiple commits into a single commit. It helps in maintaining a cleaner and more readable commit history.
A developer discovers that confidential files were accidentally committed to a public Git repository. What steps should be taken to resolve this?
- Identify and note down the commit hash. Use git reset or git revert to undo the commit.
- Use git rm to remove the files from the repository, commit the changes, and push.
- Create a new branch, cherry-pick the desired commits without the confidential files, and push.
- Use git filter-branch to remove the files from the entire history and force push the updated repository.
Option 2 involves removing the confidential files and making a clean commit, ensuring that sensitive information is not exposed. Other options may have drawbacks or potential risks, such as force-pushing to a shared repository.
What is a Git Hook primarily used for?
- Executing custom scripts
- Managing branches
- Resolving merge conflicts
- Creating repositories
Git hooks are scripts that run automatically before or after specific Git events. They are primarily used for executing custom scripts, such as enforcing coding standards or triggering automated tests.
How do branching strategies in Git influence project management in large enterprises?
- Facilitate Parallel Development
- Slow Down the Development Process
- Minimize Collaboration
- Increase Code Conflicts
Git branching strategies enable parallel development, allowing teams to work on features independently. This enhances collaboration and accelerates project delivery by avoiding conflicts during simultaneous development.
What Git feature is particularly useful for managing different releases in open source projects?
- Git Branching
- Git Forking
- Git Merging
- Git Cloning
Git branching is particularly useful for managing different releases in open source projects. Each branch can represent a different version or release, allowing for parallel development and easy maintenance of multiple code bases.
The git _______ command is used to change a commit message that hasn't been pushed yet.
- commit --amend
- commit --modify
- commit --edit
- commit --change

When setting up a new remote repository, the command git remote add origin _______ is used.
- https://github.com/user/repo.git
- origin
- master
- git remote
The correct option is a. https://github.com/user/repo.git. This option represents the URL of the remote repository, and 'origin' is a common name given to the remote. While 'origin' is used in the command, it is not a placeholder for the repository URL. It's important to correctly specify the remote repository's URL when adding a remote to your local repository to establish a connection for pushing and pulling changes.
What is a common use of git stash in Git?
- Discarding changes
- Storing changes temporarily
- Applying changes to the remote repository
- Deleting the entire repository
Git stash is commonly used to temporarily store changes that are not ready to be committed. This is useful when you need to switch to a different branch or address an urgent issue, allowing you to save your work without committing it.
