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.
During a project audit, you need to find out when a specific bug was introduced. What Git feature can help you trace the origin of this bug?
- blame
- log
- bisect
- show
The correct option is bisect. The git bisect command allows you to perform a binary search through the commit history to identify when a bug was introduced. By marking good and bad commits, Git efficiently narrows down the faulty commit range.
A developer wants to automate the deployment of their application to a server after each commit to the master branch on GitLab. Which Git feature should they utilize?
- GitLab CI/CD
- Git Submodules
- Git Merge Requests
- Git Stash
To automate the deployment process after each commit to the master branch on GitLab, the developer should utilize GitLab CI/CD (Continuous Integration/Continuous Deployment). GitLab CI/CD allows developers to define and automate pipelines for building, testing, and deploying their applications.
Customizing the __________ Hook can help enforce coding standards before code is pushed.
- Pre-push
- Pre-receive
- Post-commit
- Post-receive
The correct option is Pre-receive. This hook is executed on the server when you receive a push. Customizing it allows you to enforce coding standards before accepting the pushed code.
