When would you typically use a release tag in Git?
- To mark a commit as a stable release point
- To indicate the latest commit
- To denote a feature branch
- To identify a commit for debugging purposes
Release tags in Git are commonly used to mark specific commits as stable release points. This makes it easier to reference and deploy specific versions of the code.
How does Git enhance collaboration in a Continuous Integration/Continuous Deployment (CI/CD) pipeline?
- Git Pull Requests
- Git Submodules
- Git Remote
- Git Stash
Git Pull Requests facilitate collaboration in a CI/CD pipeline by allowing team members to propose changes, discuss them, and then merge them into the main codebase. This process ensures a controlled and collaborative integration of new features or bug fixes.
How does a Git Subtree differ from a Git Submodule?
- Independent repositories
- Nested repositories
- Code isolation
- Branch merging
Git Subtree allows you to insert an independent Git repository into a subdirectory of another Git repository, whereas Git Submodules maintain a connection to a specific commit in the external repository. Subtree includes the external repository's code directly, while Submodule references it as a separate project.
Agile development benefits from Git's __________, which allows for quick pivots in project direction.
- Branching
- Reset
- Staging
- Fast-forward
Git's branching feature is beneficial in Agile development because it enables quick pivots. Developers can create branches to experiment with new ideas without affecting the main codebase, facilitating flexibility and experimentation.
In the context of Git, what is a 'sparse checkout' and how does it improve performance with large repositories?
- Sparse checkout is a feature that fetches only the latest commit, reducing repository size.
- Sparse checkout is a mechanism for excluding specific files or directories during checkout.
- Sparse checkout allows for parallel processing of Git commands, improving speed.
- Sparse checkout reduces the number of contributors, streamlining performance.
A 'sparse checkout' in Git allows users to checkout only a subset of files or directories, reducing the size of the working directory. This is beneficial in large repositories, as it improves performance by excluding unnecessary files from the working directory.
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.
A clean Git history is often maintained by using _______ to combine commits before merging.
- git squash
- git merge --squash
- git combine
- git rebase -i
The correct option is git rebase -i. Interactive rebase (-i) allows you to combine, edit, or reorder commits interactively. Squashing commits during interactive rebase helps create a cleaner and more organized Git history before merging into the main branch.
When migrating to Git, it's crucial to convert the old VCS __________ into Git commits.
- History
- Branches
- Tags
- Commits
During the migration process to Git, converting the old version control system's commits into Git commits preserves the project's history, allowing for a seamless transition and maintaining version information.
