When cherry-picking a commit, Git creates a new commit with a different ________ even if the content is the same.
- Hash
- Branch
- Message
- Timestamp
When cherry-picking a commit in Git, it generates a new commit with a different hash to maintain uniqueness, even if the content is identical. The hash is a cryptographic checksum of the commit, and altering the commit creates a new hash.
In the Gitflow workflow, the ________ branch contains the official release history.
- Master
- Develop
- Release
- Hotfix
In Gitflow, the "Release" branch contains the official release history, and it is where code freezes in preparation for a new release. This branch helps manage versioning effectively.
Which Git Hook is triggered before a commit is finalized?
- pre-commit
- post-commit
- pre-receive
- post-receive
The pre-commit hook is triggered before a commit is finalized. It allows you to inspect the changes that are about to be committed and optionally abort the commit. This hook is useful for tasks like code formatting or running pre-commit tests.
How does Git support Agile development principles like collaboration and flexibility?
- Through its branching and merging capabilities
- By enforcing a strict development process
- By limiting the number of developers in a project
- By providing a centralized code repository
Agile Development with Git
In an enterprise setting, a Git repository's performance is degrading over time due to accumulated obsolete data. What Git maintenance practice would be most effective?
- Git garbage collection
- Git cloning
- Git rebase
- Git cherry-pick
The most effective Git maintenance practice in this scenario is running Git garbage collection. It helps clean up unnecessary data, optimize the repository, and improve overall performance.
A _______ branch is typically used for preparing, polishing, and finalizing a release.
- release
- feature
- master
- hotfix
A release branch is created to prepare, polish, and finalize a release. It is used to stabilize the code and ensure that it is ready for production before merging it into 'master.'
A developer needs to apply a hotfix from the master branch to a release branch without merging other changes. What Git feature should they use?
- Cherry-pick
- Merge
- Rebase
- Clone
The correct option is Cherry-pick. This Git feature allows a developer to select a specific commit and apply it to another branch, making it ideal for applying isolated changes such as hotfixes. Unlike merge or rebase, cherry-pick targets a single commit.
During a database upgrade, a team needs to apply incremental schema changes stored in Git. What strategy should they follow to ensure a smooth transition?
- Feature Branching
- Git Tagging
- Git Rebase
- Git Merge
The team should follow the Git Rebase strategy to apply incremental schema changes during the database upgrade. Git Rebase allows the team to incorporate changes from one branch into another, providing a cleaner and more linear history. This is especially useful in scenarios like database upgrades where maintaining a clean history is crucial for understanding the sequence of changes. Git Rebase helps avoid unnecessary merge commits and simplifies the history, making the transition smoother.
A team wants to automatically test and deploy features as soon as they are pushed to a specific Git branch. Which CI/CD practice aligns with this?
- Continuous Integration (CI)
- Continuous Deployment (CD)
- Continuous Delivery (CD)
- Continuous Testing (CT)
Continuous Deployment is the practice of automatically deploying code changes to a production environment after passing automated tests. This aligns with the goal of testing and deploying features as soon as they are pushed to a specific Git branch, ensuring a streamlined development process.
How does GitHub Actions integrate with Git workflows for CI/CD?
- Triggered by events in the repository
- Automated code deployment
- Version control system
- Code review process
GitHub Actions are triggered by events such as pushes to the repository. It is commonly used for automating CI/CD pipelines, which includes tasks like running tests and deploying code. Understanding these integrations is crucial for efficient CI/CD processes in a Git-based workflow.
