The ________ model in Git is ideal for open-source projects where contributors do not have direct write access to the main repository.
- Forking
- Centralized
- Distributed
- Feature Branching
The forking model in Git is ideal for open-source projects where contributors do not have direct write access to the main repository. Contributors fork the main repository, make changes in their forked copies, and then create pull requests to propose changes to the main repository. This model allows for a decentralized contribution workflow, making it easier for multiple contributors to work on the project simultaneously.
To ignore file changes in your working directory, you should update the _________ file in your Git repository.
- .gitignore
- .gitconfig
- .ignore
- .exclude
The correct option is .gitignore. This file contains a list of file patterns that Git should ignore when tracking changes in your working directory. It's useful for excluding temporary files, build artifacts, and other files that shouldn't be part of your version control.
Changing the history of public branches is generally discouraged because it can lead to ________ for other collaborators.
- synchronization issues
- confusion
- conflict resolution
- frustration
The correct option is (c) conflict resolution. Altering the history of public branches can create conflicts for other collaborators, making it challenging to resolve differences in the repository. It's a good practice to avoid history changes on shared branches.
In Git, a _______ merge is used to integrate changes from one branch into another without creating a merge commit.
- Fast-Forward
- Squash
- Recursive
- Cherry-pick
The correct option is Fast-Forward. A Fast-Forward merge in Git is used to integrate changes from one branch into another when there are no new changes on the target branch. It performs a simple "move forward" of the branch pointer, avoiding the creation of a merge commit.
How can you identify the specific commits that introduced conflicting changes during a merge in Git?
- git blame
- git show
- git diff
- git log
When a merge conflict occurs, using git diff will help identify the conflicting changes introduced by specific commits. This command shows the differences between the working directory and the index or a tree, making it useful for inspecting changes.
How can you revert a pushed commit in Git without losing history?
- git reset
- git revert
- git rollback
- git backout
To revert a pushed commit without losing history, use git revert. This command creates a new commit that undoes the changes introduced by the previous commit, preserving the commit history and avoiding force pushes.
Which Git hook would you use to run scripts before a commit is finalized?
- pre-commit
- post-commit
- pre-push
- post-receive
The pre-commit hook in Git is used to run scripts and checks before a commit is finalized, allowing developers to perform pre-commit validations.
In Git, _______ can be used to temporarily switch to another branch without committing the current work.
- git checkout
- git merge
- git branch
- git stash
In Git, the command 'git checkout' is used to switch between branches. It allows you to navigate between different branches without committing your current changes.
A developer frequently uses long and complex Git commands. Which feature of Git can they use to create shortcuts for these commands?
- Git Alias
- Git Tag
- Git Remote
- Git Branch
Git Alias is a feature that allows developers to create shortcuts for long and complex Git commands, enhancing efficiency and reducing the likelihood of errors in command execution.
What does the git log command display in a Git repository?
- List of all branches.
- Commit history with detailed information.
- Uncommitted changes in the working directory.
- Status of files in the staging area.
The git log command displays the commit history of the repository. It includes information such as the commit hash, author, date, and commit message. This helps in tracking changes, understanding the project's development timeline, and identifying specific commits for reference or debugging purposes.
To enhance security, sensitive data in a Git repository should be stored in an encrypted ________.
- Blob
- Object
- File
- Repository
Storing sensitive data in an encrypted object ensures that unauthorized users cannot access or view the confidential information, adding an extra layer of security to the Git repository.
To handle complex project structures in Git, large projects often rely on ________ to manage different components.
- Branching
- Submodules
- Merging
- Tags
In Git, submodules are used to manage different components of a project. Submodules allow you to include other Git repositories as a subdirectory, enabling better organization of complex project structures.
