Customizing the __________ Hook can help enforce coding standards before code is pushed.
- Pre-push
- Pre-receive
- Post-commit
- Post-receive
The correct option is Pre-receive. This hook is executed on the server when you receive a push. Customizing it allows you to enforce coding standards before accepting the pushed code.
A developer wants to automate the deployment of their application to a server after each commit to the master branch on GitLab. Which Git feature should they utilize?
- GitLab CI/CD
- Git Submodules
- Git Merge Requests
- Git Stash
To automate the deployment process after each commit to the master branch on GitLab, the developer should utilize GitLab CI/CD (Continuous Integration/Continuous Deployment). GitLab CI/CD allows developers to define and automate pipelines for building, testing, and deploying their applications.
During a project audit, you need to find out when a specific bug was introduced. What Git feature can help you trace the origin of this bug?
- blame
- log
- bisect
- show
The correct option is bisect. The git bisect command allows you to perform a binary search through the commit history to identify when a bug was introduced. By marking good and bad commits, Git efficiently narrows down the faulty commit range.
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.
The team needs to integrate a project within another project while maintaining separate version control histories. Which Git feature is the most appropriate?
- Subtree Merge
- Cherry-pick
- Rebase
- Merge Commit
Subtree merge allows integrating an external project into another by merging in only the parts needed, maintaining separate histories. It's useful for combining projects without losing their individual version control contexts.
To cherry-pick a specific commit, you use the command git cherry-pick ________.
- commit-hash
- git-apply
- git-merge
- git-rebase
The correct option is a) commit-hash. This command allows you to apply the changes introduced by a specific commit onto your current branch. You need to provide the commit hash of the desired commit.
How does Git's branching model enhance Agile methodologies in large-scale development?
- Facilitates parallel development
- Simplifies project management
- Reduces the need for communication
- Improves code quality
Git's branching model enhances Agile methodologies by facilitating parallel development. Multiple branches enable teams to work on different features simultaneously, promoting collaboration and faster delivery. The ability to isolate features in branches helps manage project complexity and supports Agile principles of adaptability and quick response to changes.
_______ in Git are essential for maintaining different versions of database scripts for various features.
- Tags
- Branches
- Commits
- Merges
Tags in Git are crucial for maintaining different versions of database scripts for various features. Tags provide a way to mark specific points in the version history, making it easier to reference and deploy specific releases of database scripts. This is especially useful when managing multiple versions of a database schema for different features or releases.
Your team is reviewing a complex set of changes. How can you use Git to navigate through each change individually to discuss them?
- git log -p
- git diff
- git blame
- git bisect
To navigate through each change individually and discuss them, you can use git log -p to show the commit history with the associated changes. git diff shows the changes in the working directory, but it's not specific to individual commits. git blame is used to show changes in a file, and git bisect is used for binary search to find a specific commit causing an issue.
