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.
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 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.
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.
The git ________ command can be particularly useful in IDEs for exploring code history.
- log
- status
- diff
- commit
The "git log" command displays the commit history of the repository. In an IDE, this can be useful for developers to understand the chronological order of changes, who made them, and the associated commit messages. It aids in exploring the code history and tracking changes over time.
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.
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.
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.
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.
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.
