In a project with multiple contributors, two developers have made different changes to the same file. What Git feature will help resolve this when merging?
- Cherry-pick
- Merge Conflict Resolution
- Stash
- Bisect
When there are conflicting changes in the same file, Git's merge conflict resolution feature helps developers manually resolve conflicts and merge the changes successfully.
What is the impact of having a large number of branches in a Git repository on its performance?
- A large number of branches has no impact on Git repository performance.
- More branches lead to faster Git operations due to parallel processing.
- Having many branches can slow down Git operations like cloning and fetching.
- Git performance is not affected by the number of branches in a repository.
Having a large number of branches in a Git repository can negatively impact performance, especially during operations like cloning and fetching. Each branch adds overhead, and repositories with excessive branches may experience slower operations.
To see a graphical representation of the commit history, you can use git log --_______.
- graph
- oneline
- pretty
- graphoneline
The correct option is git log --graph. This option provides a graphical representation of the commit history, showing branches and merges.
What is a common use of git stash in Git?
- Discarding changes
- Storing changes temporarily
- Applying changes to the remote repository
- Deleting the entire repository
Git stash is commonly used to temporarily store changes that are not ready to be committed. This is useful when you need to switch to a different branch or address an urgent issue, allowing you to save your work without committing it.
When setting up a new remote repository, the command git remote add origin _______ is used.
- https://github.com/user/repo.git
- origin
- master
- git remote
The correct option is a. https://github.com/user/repo.git. This option represents the URL of the remote repository, and 'origin' is a common name given to the remote. While 'origin' is used in the command, it is not a placeholder for the repository URL. It's important to correctly specify the remote repository's URL when adding a remote to your local repository to establish a connection for pushing and pulling changes.
The git _______ command is used to change a commit message that hasn't been pushed yet.
- commit --amend
- commit --modify
- commit --edit
- commit --change
The correct option is commit --amend. This command allows you to modify the last commit's message. It's useful when you need to make small changes or corrections to the commit message before pushing it to the remote repository.
What Git feature is particularly useful for managing different releases in open source projects?
- Git Branching
- Git Forking
- Git Merging
- Git Cloning
Git branching is particularly useful for managing different releases in open source projects. Each branch can represent a different version or release, allowing for parallel development and easy maintenance of multiple code bases.
In complex workflows, pull requests may be used to merge changes from _______ branches to _______ branches before reaching the main branch.
- feature, development, release, bugfix
- topic, staging, master, hotfix
- feature, release, master, hotfix
- development, feature, master, bugfix
In complex workflows, pull requests are often utilized to merge changes from feature branches to development branches before reaching the main branch. This helps in organizing and reviewing changes before integration.
What advanced Git feature can be crucial for performance optimization in large-scale enterprise projects?
- Git hooks
- Git submodules
- Git bisect
- Git LFS (Large File Storage)
Git LFS is essential for managing large files in enterprise projects. It optimizes performance by efficiently handling and storing large assets, preventing them from slowing down the repository.
A DevOps team is implementing a new feature across different environments (development, testing, production). What Git strategy should they adopt to ensure smooth transitions and tracking?
- Feature Branches
- Git Tags
- Forking
- Rebasing
The DevOps team should adopt the strategy of using feature branches. Feature branches allow developers to work on new features or fixes independently in isolation. This helps in smooth transitions across different environments by merging the feature branch into each environment as needed. It also facilitates tracking changes related to specific features.
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.
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.
