In Git, a '_______ merge' is used to integrate changes from one branch into another, creating a new commit even if a fast-forward merge is possible.
- Fast-forward
- Recursive
- Squash
- Three-way
In Git, a 'Three-way merge' is used to integrate changes from one branch into another, creating a new commit even if a fast-forward merge is possible. This merge strategy involves comparing the changes in three branches—the two branch tips and their common ancestor. It is particularly useful when there are conflicting changes on both branches.
Which Git command is used to undo the last commit while keeping the changes in the working directory?
- git reset HEAD~1
- git revert HEAD
- git commit --amend
- git checkout -- .
The correct option is git reset HEAD~1. This command resets the last commit while keeping the changes in the working directory. The HEAD~1 refers to the commit before the last one.
Using SSH ________ is a recommended method for secure authentication in Git.
- keys
- handshake
- certificates
- protocols
In Git, using SSH keys is a recommended method for secure authentication. SSH keys involve the use of asymmetric cryptography to secure the communication between the local and remote repositories.
In a distributed team, a developer needs to integrate a hotfix into multiple branches efficiently. What Git approach or feature should they use?
- Git cherry-pick
- Git merge --squash
- Git rebase --onto
- Git submodules
The Git approach that allows a developer to integrate a hotfix into multiple branches efficiently is Git cherry-pick. Cherry-pick enables the selection of specific commits and applies them to another branch, making it suitable for applying hotfixes to multiple branches without merging the entire branch.
What strategies can be employed in Git to manage a large number of contributors in an open source project?
- Implementing access controls and code reviews
- Utilizing branches effectively
- Utilizing Git submodules
- Implementing a monolithic repository approach
In a large open source project, effective branch management and code review processes are essential to ensure a smooth collaboration among contributors. Utilizing branches effectively allows parallel development and collaboration without conflicts, making it a crucial strategy.
The strategy of _______ involves integrating changes from the main branch frequently to minimize conflicts.
- Rebase
- Clone
- Fork
- Pull Request
The correct option is Rebase. Rebase is a strategy in Git that involves integrating changes from one branch into another by moving or combining a sequence of commits. It helps maintain a cleaner commit history and minimizes conflicts during integration.
How does Git integration in an IDE enhance the coding process?
- Streamlines collaboration with teammates
- Enables syntax highlighting and code completion
- Integrates with version control for tracking changes
- Provides AI-based code suggestions
Git integration in IDEs primarily focuses on version control, allowing developers to track changes. It doesn't directly impact syntax highlighting or code suggestions, which are IDE-specific features.
A developer accidentally commits a large binary file. What Git feature should they use to remove this file from history while retaining current changes?
- rebase
- reset
- filter-branch
- reflog
The correct option is filter-branch. This Git command allows the modification of the repository's commit history, including the removal of sensitive or large files. It's crucial to be cautious when using this command as it can rewrite history, impacting collaborators.
In Git, the __________ file can be used to enforce code quality standards across all project contributors.
- .gitignore
- .gitattributes
- .gitconfig
- .gitkeep
The .gitattributes file is used to enforce code quality standards across all project contributors by specifying attributes for files in the repository. It helps in maintaining consistency and best practices.
In what scenario is rebasing preferred over merging in Git?
- Rebasing is preferred when working on a feature branch that you want to keep clean and incorporate the latest changes from the main branch.
- Rebasing should be used when there are conflicts between branches to create a new, unified commit.
- Rebasing is suitable only for small projects with a limited commit history.
- Rebasing is recommended when you want to preserve the existing branch structure and history.
In-depth Rebasing is beneficial for creating a linear history, especially when working on feature branches, to avoid unnecessary merge commits.
