What is the primary purpose of a version control system?
- A version control system is used for code collaboration.
- A version control system is used for debugging code.
- A version control system is used for file backup.
- A version control system is used for tracking changes in code.
The primary purpose of a version control system, like Git, is to track changes in code and manage different versions of files. It allows developers to collaborate, review changes, and revert to previous versions if needed.
Your team decides to enforce a linear history on the main branch. Which Git feature would be most appropriate to achieve this?
- merge
- rebase
- squash
- cherry-pick
The correct option is rebase. Rebasing helps create a linear history by incorporating changes from one branch onto another, eliminating unnecessary merge commits. This promotes a cleaner and more straightforward history, especially on the main branch.
What are the implications of force pushing (git push --force) in a collaborative Git repository?
- It's a standard push operation
- It overwrites the remote branch with local changes
- It creates a new branch remotely
- It prompts collaborators for approval
Force pushing overwrites the remote branch with local changes, potentially causing conflicts for collaborators. It should be used cautiously to avoid disrupting others' work.
To handle large codebases in enterprise environments, Git can be integrated with ________ for enhanced performance.
- Jenkins
- Docker
- Bitbucket
- GitLab
Git can be integrated with Docker for enhanced performance in handling large codebases. Docker provides containerization, allowing consistent environments across different stages of the development lifecycle. This integration aids in efficient deployment and scalability.
What command is used to start a new branch in Git?
- git branch
- git init
- git new-branch
- git checkout -b
The 'git checkout -b' command is used to create and switch to a new branch in one step. It is a convenient shortcut for creating feature branches.
How does the 'Gitflow' branching strategy differ from 'feature branching'?
- Gitflow follows a predefined branching model with dedicated branches for features, releases, and hotfixes. Feature branching involves creating branches for individual features but lacks the predefined structure of Gitflow.
- Gitflow is a more flexible strategy compared to feature branching. Feature branching is a simplified approach suitable for small projects.
- Gitflow and feature branching are essentially the same; they both involve creating branches for new features.
- Gitflow is a version control system, whereas feature branching is a code review practice.
Gitflow is a branching model that provides a predefined structure for managing feature development, releases, and hotfixes. It introduces branches like 'feature,' 'release,' and 'hotfix,' which serve specific purposes. On the other hand, feature branching is a simpler approach where each new feature gets its own branch. The key difference lies in the predefined structure that Gitflow offers, making it more suitable for complex projects.
In a complex project, git rebase -i offers an interactive mode to ________ commits.
- Delete
- Combine
- Revert
- Squash
The correct option is b. Combine. When you use git rebase -i, you can interactively choose what to do with each commit, including combining or modifying them. This is useful for cleaning up commit history in a complex project.
When transitioning a legacy codebase to Git, it's important to set up a proper .git________ to ignore unnecessary files.
- ignore
- exclude
- filter
- config
In Git, the .gitignore file is used to specify intentionally untracked files that Git should ignore. This helps in maintaining a clean working directory and prevents unnecessary files from being committed.
The command git _______ can help in visualizing the branching and merging history in a repository.
- log
- status
- diff
- show
The 'git log' command provides a detailed history of commits, including branching and merging. It helps visualize the chronological order of commits in the repository.
In the context of Git, what is a 'Fork' primarily used for?
- Creating a new branch in a repository
- Cloning a repository from one remote to another
- Diverging from the main codebase
- Creating a duplicate of a repository
In Git, a 'Fork' is primarily used for cloning a repository from one remote to another. Forking is commonly associated with collaborative development on platforms like GitHub, where a user can fork a repository to create their copy. This copy is independent and can be modified without affecting the original repository. Forking is a fundamental concept in open-source collaboration and contributes to the decentralized nature of Git.
