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 developer wants to temporarily save changes without committing them to maintain a clean project history. What Git feature should they use?
- git stash
- git branch
- git commit --amend
- git tag
The correct option is a. git stash. This command allows the developer to save changes without committing them and revert the working directory to the last commit. It's useful for switching to a different branch or applying changes later. git branch is used to create, list, or delete branches. git commit --amend is used to modify the last commit, and git tag is used to create tags.
The git _______ command creates a new commit that undoes all of the changes made in a specified commit.
- revert
- reset
- undo
- backout
The correct option is revert. The git revert command is used to create a new commit that undoes the changes made in a previous commit, effectively reverting the repository's state to a previous point in 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.
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.
