A team notices that their feature branch is several commits behind the main branch. What Git strategy should they employ to update their branch without cluttering the commit history?
- Merge the main branch into the feature branch
- Rebase the feature branch onto the main branch
- Cherry-pick the changes from the main branch and apply to the feature branch
- Create a new branch from the main branch and merge it into the feature branch
To update a feature branch without cluttering the commit history, it's advisable to use rebase. This integrates the latest changes from the main branch into the feature branch, maintaining a linear history and avoiding unnecessary merge commits.
In Git, what is the result of executing a 'merge' command?
- Creates a new branch
- Combines changes from different branches
- Deletes a branch after merging
- Reverts all changes made in a branch
The 'merge' command in Git combines changes from different branches into the current branch. It integrates the changes, creating a new commit that represents the combined state of the branches.
What is the purpose of cherry-picking in Git?
- Apply specific commits
- Merge two branches
- Revert changes
- Delete a branch
Cherry-picking in Git allows you to select specific commits from one branch and apply them to another. This is useful when you only want certain changes from one branch without merging the entire branch.
In a collaborative project using Git, what is the purpose of a pull request?
- A pull request is a mechanism for contributors to propose changes to the main repository and request that someone review and merge their changes.
- Pull requests are used to fetch changes from a remote repository.
- Pull requests are only necessary in Forking workflow, not in Feature Branch workflow.
- Pull requests are equivalent to merge requests and are used only for merging code.
Pull requests facilitate code review, discussion, and automated testing before changes are merged into the main branch, promoting collaboration and maintaining code quality.
To automate the execution of tests every time a new commit is pushed, a _________ Git hook can be utilized.
- Pre-receive
- Post-receive
- Update
- Pre-commit
Git hooks are scripts that Git executes before or after events such as commit, push, and receive. The Post-receive hook is suitable for automated tasks after a successful push.
In managing open source projects with Git, the ________ file is crucial for describing project guidelines and contribution procedures.
- README
- LICENSE
- CONTRIBUTING
- CODEOWNERS
The CONTRIBUTING file in a Git repository is essential for providing guidelines on how developers can contribute to the project. It outlines coding standards, processes for submitting issues or pull requests, and other contribution-related information.
In the context of enterprise, what is a key benefit of implementing Git LFS (Large File Storage)?
- Improved Version Control for Large Files
- Faster Commit and Push Operations
- Enhanced Collaboration on Small Files
- Reduced Storage Costs for Small Repositories
Git LFS provides better version control for large files, making it suitable for enterprises dealing with multimedia assets like images and videos. It doesn't significantly impact small files or storage costs for smaller repositories.
When resolving conflicts, the git _______ command allows a user to navigate through conflicted files.
- Resolve
- Merge
- Diff
- Checkout
The correct option is Checkout. The git Checkout command in the context of conflict resolution allows a user to navigate through conflicted files. It helps in selecting the desired changes and resolving conflicts during the merge process.
What is the purpose of a .gitignore file in a Git repository?
- Specifies files and directories that should be ignored by Git.
- Lists all files in the repository.
- Tracks changes in the repository.
- Adds new files to the repository.
The .gitignore file is used to specify intentionally untracked files that Git should ignore. This is useful for excluding files generated by the build process or system files that should not be committed. It helps in maintaining a clean repository by avoiding the accidental addition of irrelevant files.
For advanced CI/CD workflows, Git's ________ feature can be used to manage code reviews effectively.
- Pull Request
- Stash
- Rebase
- Bisect
In Git, the feature used for managing code reviews effectively in advanced CI/CD workflows is the Pull Request. Pull Requests provide a structured way for team members to review and discuss changes before merging them into the main codebase. This is crucial for maintaining code quality and collaboration in larger projects.
After completing a significant feature, a developer wants to mark the current state of the repository for future reference. Which Git feature would be most appropriate?
- Tag
- Branch
- Commit
- Stash
The correct option is Tag. Tags in Git are used to mark specific points in history as being important. This is commonly done to capture a release point or mark a significant version in the repository. Unlike branches, tags are generally not moved once created.
A pull request is a request to merge a branch called _______ into another branch in a Git repository.
- feature_branch
- source_branch
- target_branch
- merge_branch
In a pull request, the branch to be merged is the target branch, where the changes will be applied.
