What is the role of Git in Continuous Integration (CI) workflows?
- Facilitates version control for collaborative development
- Manages the build and deployment process
- Monitors server performance during CI
- Automates testing in the CI pipeline
Git provides version control, enabling collaboration among developers. While it's integral to CI, Git itself doesn't manage the CI workflow. CI involves automating builds, testing, and deployment, which is beyond Git's scope.
To handle large-scale code migrations efficiently, Git's __________ feature can be used to manage project dependencies.
- submodules
- stashes
- reflog
- bisect
Git's submodules feature is utilized to manage project dependencies, allowing for efficient handling of large-scale code migrations and keeping projects modular and maintainable.
When transitioning to Git, what strategy helps in preserving the history of a legacy codebase?
- Squashing all commits into one
- Creating a new repository and discarding the old history
- Importing the entire history into a single commit
- Git Clone
Importing the entire history into a single commit helps preserve the history of a legacy codebase when transitioning to Git. This maintains a clear and complete record of the codebase's evolution.
A development team is working on a feature that will take several weeks to complete. Which Git workflow model would best support their needs for isolation and regular integration?
- Feature Branch Workflow
- Gitflow Workflow
- Forking Workflow
- Centralized Workflow
In the Gitflow workflow, the development team can work on feature branches, providing isolation for their work. Regular integration can be achieved through the use of feature branches and the designated branches for development, release, and master. This model is suitable for longer-term projects with distinct phases.
Which command in Git allows you to view the commit history?
- git branch
- git diff
- git log
- git status
The git log command in Git allows you to view the commit history of a repository. It displays a list of all commits, including their unique identifiers, authors, timestamps, and commit messages.
What are the potential drawbacks of using a centralized workflow in a large, distributed team?
- Limited parallel development
- Increased collaboration challenges
- Difficulty in managing conflicts
- Slower release cycles
In a centralized workflow, all developers work on a single branch, leading to limited parallel development. This can result in bottlenecks, especially in large, distributed teams where collaboration across different locations is essential.
A team is handling an urgent bug fix in a production application. Which branch in the Gitflow model should they use?
- Feature Branch
- Release Branch
- Hotfix Branch
- Master Branch
The Hotfix Branch in the Gitflow model is designed for urgent bug fixes in the production environment. This branch allows the team to address critical issues quickly without disrupting the regular development workflow.
Which feature of Git can significantly improve code quality when compared to older VCS systems?
- Git hooks
- Git branches
- Git stash
- Git tags
Git branches are a powerful feature that can significantly improve code quality. They enable developers to work on isolated features or fixes, reducing the chances of conflicts and making collaboration more efficient.
How does Git's data model handle changes across different branches?
- Merge commits
- Independent snapshots
- Cherry-picking
- Branching and Merging
Git's data model represents each commit as an independent snapshot of the entire project. This allows changes across branches to be isolated, and Git efficiently handles merging these snapshots during branch integration.
The git _______ command can be used to temporarily store uncommitted changes and clear the working directory.
- stash
- save
- store
- backup
The correct option is stash. The git stash command is used to save changes that are not ready to be committed yet. It allows you to temporarily store your modifications and revert the working directory to match the last commit. This is useful when you need to switch branches or apply changes later.
