What is a common challenge when managing large files in Git?
- Difficulty in cloning and fetching
- Limited storage space
- Slow performance
- Difficulty in merging changes
When managing large files in Git, slow performance is a common challenge. Git may become sluggish when handling large files, impacting operations like cloning and fetching. This is because Git is not optimized for handling large files efficiently.
In distributed teams using Git, how is work typically coordinated?
- Through regular team meetings
- Via a central coordinator who controls all commits
- Using a distributed version control model
- Email communication only
In distributed teams using Git, work is typically coordinated through a distributed version control model, allowing team members to work independently and merge changes seamlessly.
The .git/_______ directory contains all of the necessary repository metadata for Git.
- index
- objects
- hooks
- refs
In Git, the .git/objects directory stores all the necessary repository metadata, including object data such as commits and trees. The correct option is ' objects'.
What are the best practices for managing large binary files in Git when transitioning a legacy codebase?
- Use Git LFS for versioning large files
- Store large files in the same repository
- Compress large binary files and store in Git
- Use submodules to manage large binary files
Managing Large Binary Files
A team is working on a feature branch and wants to integrate their work into the main project. What should they initiate for review and discussion?
- Git Pull Request
- Git Merge
- Git Branching
- Git Commit
In Git, a Pull Request is commonly used to initiate a review and discussion when merging feature branches into the main project. It allows team collaboration and thorough review before integration.
The git __________ command is essential for maintaining the integrity and performance of a large repository by cleaning up redundant data.
- git prune
- git reset
- git clean
- git gc
The git gc (garbage collection) command is crucial for optimizing a Git repository by cleaning up unnecessary files and optimizing the repository's data structure. It helps in reducing repository size and improving performance.
A developer accidentally pushes a commit containing a critical security vulnerability. What Git feature should they use to handle this situation?
- Revert commit
- Amend commit
- Git reset
- Git stash
In this scenario, the developer should use the 'Revert commit' feature to create a new commit that undoes the changes introduced by the problematic commit. This ensures a clear history while addressing the security vulnerability without modifying the existing commit history.
What is a common cause of merge conflicts in Git?
- Concurrent changes to the same file
- Creating a new branch
- Adding commits to the repository
- Checking out a branch
Merge conflicts occur when two or more branches have made changes to the same part of a file. Git cannot automatically merge these changes, and manual intervention is required to resolve the conflicts.
The ability to __________ in Git aids in maintaining a clean and manageable codebase in large projects.
- Rebase
- Squash
- Amend
- Cherry-pick
The ability to squash commits in Git is essential for maintaining a clean and manageable codebase. Squashing combines multiple commits into a single, well-organized commit, helping to streamline the commit history and make it more comprehensible.
After a failed merge attempt, a developer needs to undo the merge to maintain project stability while resolving conflicts. What Git feature or command should they use?
- git reset --hard HEAD
- git revert HEAD
- git checkout -b new-branch
- git clean -df
The git reset --hard HEAD command is used to undo the last commit and return the repository to the state of the last successful merge. This allows the developer to start fresh and reattempt the merge while resolving conflicts. Other options like git revert and git clean have different purposes and do not address the need to undo the merge.
