Which Git feature is commonly used to trigger a CI/CD pipeline?
- Git Hooks
- Git Stash
- Git Submodules
- Git Branches
Git Hooks are scripts triggered by specific Git events, making them suitable for CI/CD pipeline triggers. Stash, submodules, and branches serve different purposes in Git but are not directly tied to CI/CD.
After reviewing a repository's history, a team leader finds an unauthorized access. What Git practice could have prevented this?
- Branch protection
- Code signing
- Git hooks
- Commit squashing
Branch protection can prevent unauthorized access by defining rules that restrict certain actions on specific branches. By enforcing access controls, the team leader could have prevented unauthorized changes and maintained a secure repository.
What is the purpose of the git commit command?
- Save changes to the local repository
- Upload changes to the remote repository
- Discard local changes
- Create a new branch
The purpose of the git commit command is to save changes to the local repository. It creates a new commit with the changes you have made, providing a way to track the history of your project.
How can you find a commit in the Git history that introduced a bug using the git bisect command?
- git log -S
- git bisect start
- git blame
- git revert
The correct option is B. git bisect start is used to perform a binary search through the commit history, helping identify the commit that introduced a bug. The bisect command automates the process of checking out different commits until the problematic one is found.
The command git _______ is used to clone a remote repository to your local machine.
- pull
- fetch
- clone
- push
The git clone command is used to clone a remote repository to your local machine. It copies the entire repository, including all branches and commit history, to your local system.
_________ in Git can be automated in an IDE to ensure code quality before commits.
- Code Signing
- Code Linting
- Code Obfuscation
- Code Encryption
Code linting in Git can be automated in an IDE to ensure code quality before commits. Linting checks the code for potential errors, stylistic issues, and adherence to coding standards, helping developers catch and fix issues early in the development process.
Describe the role of 'feature branches' in Git's branching model.
- Long-lived branches for ongoing features
- Temporary branches for hotfixes
- Branches for experimental changes
- Short-lived branches for documentation
'Feature branches' are long-lived branches created for ongoing features or tasks. They allow developers to work on features independently and then integrate them back into the main branch when ready. This promotes a clean and organized development process.
How does a lightweight tag in Git differ from an annotated tag?
- Contains only a reference to a commit
- Includes additional information like a message
- Points to a branch
- Represents a merge commit
A lightweight tag in Git only contains a reference to a specific commit, while an annotated tag includes additional information such as a tagger name, email, date, and a tagging message. Annotated tags are recommended for important releases or milestones.
What is the command to list all the tags in a Git repository?
- git show-tags
- git tags
- git list-tags
- git tag -l
The correct option is git tag -l. This command lists all the tags in the Git repository. It's essential for getting an overview of available tags, especially in larger projects with numerous releases.
In the context of a large project, how does Git facilitate code reviews and quality assurance?
- Branching and pull requests for isolated code reviews
- Integration with automated testing tools
- Detailed commit history and blame feature
- Linear versioning history
Git facilitates code reviews and quality assurance in large projects through features like branching and pull requests, which enable isolated code reviews. Additionally, it integrates seamlessly with automated testing tools and provides a detailed commit history and blame feature.
