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.
An essential lesson from Git failures is the need for robust ________ in enterprise environments.
- Git Workflow
- Git Hooks
- Continuous Integration
- Branching Strategies
Failures in Git implementations often underscore the importance of robust continuous integration practices in enterprise environments. Continuous Integration ensures that changes from multiple developers are regularly integrated into the main codebase, minimizing integration issues and enhancing overall project stability. Git, when coupled with effective continuous integration, can prevent potential pitfalls and enhance the reliability of the version control process in enterprise settings.
The command to synchronize your Git Submodules with the main repository is git submodule __________.
- sync
- fetch
- update
- init
The correct option is update. This command ensures that the submodules are updated to the latest commit specified by the main repository.
During a code review, a team member identifies an issue that could potentially break the build. What Git feature allows for collaborative discussion and resolution?
- Git Stash
- Git Revert
- Git Bisect
- Git Comments
Git Comments allow collaborative discussion during code reviews. Developers can comment on specific lines of code, addressing issues, proposing solutions, and ensuring a smooth resolution process.
The ________ command in Git is commonly used to propose changes in a collaborative project.
- Commit
- Push
- Merge
- Pull
The "Push" command in Git is used to propose changes in a collaborative project by uploading the local changes to a remote repository. This is a crucial step in sharing code with others.
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.
