In a project with multiple contributors, two developers have made different changes to the same file. What Git feature will help resolve this when merging?
- Cherry-pick
- Merge Conflict Resolution
- Stash
- Bisect
When there are conflicting changes in the same file, Git's merge conflict resolution feature helps developers manually resolve conflicts and merge the changes successfully.
The git ________ command can be particularly useful in IDEs for exploring code history.
- log
- status
- diff
- commit
The "git log" command displays the commit history of the repository. In an IDE, this can be useful for developers to understand the chronological order of changes, who made them, and the associated commit messages. It aids in exploring the code history and tracking changes over time.
A developer wants to temporarily save changes without committing them to maintain a clean project history. What Git feature should they use?
- git stash
- git branch
- git commit --amend
- git tag
The correct option is a. git stash. This command allows the developer to save changes without committing them and revert the working directory to the last commit. It's useful for switching to a different branch or applying changes later. git branch is used to create, list, or delete branches. git commit --amend is used to modify the last commit, and git tag is used to create tags.
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
The correct option is commit --amend. This command allows you to modify the last commit's message. It's useful when you need to make small changes or corrections to the commit message before pushing it to the remote repository.
