In Git, __________ can be used to verify the integrity and origin of commits.
- Hash
- Signature
- Tag
- Branch
In Git, each commit is identified by a unique hash, which serves as its integrity check. The hash ensures that the commit's content and history haven't been altered, making it a reliable verification method.
Merging branches in Git typically involves the _______ branch into the current branch.
- feature
- master
- development
- source
When merging branches in Git, the changes from one branch are typically incorporated into another branch. The correct option is ' master'.
The process of systematically checking commits to find a bug using git ________ is known as bisecting.
- Diff
- Log
- Bisect
- Status
Git bisect is a powerful tool for pinpointing the introduction of bugs by systematically narrowing down the range of commits. It efficiently helps in identifying the commit where the bug was introduced.
How can you combine multiple commits into one using Git?
- Use the git merge command with the --squash option to condense multiple commits into one before merging.
- Execute git commit --combine for the commits you want to merge, specifying the commit range.
- Use the git rebase command with the -i (interactive) option to squash, fixup, or reword commits interactively.
- Create a new branch, cherry-pick the desired commits onto it, and then merge the new branch.
Git rebase with the -i option allows for interactive rebasing, including the ability to squash commits together, providing a cleaner history.
What is the importance of Git hooks in automating tasks in CI/CD pipelines?
- Code Deployment
- Code Review
- Automated Testing
- Task Automation
Git hooks are scripts triggered by Git events, such as pre-commit or post-merge. They play a vital role in CI/CD pipelines by automating tasks like code testing and deployment, ensuring a seamless development workflow.
You're working on a feature in a separate branch and want to include recent changes from the main branch. What Git strategy should you use?
- Merge
- Rebase
- Cherry-pick
- Reset
When working on a separate branch and wanting to include recent changes from the main branch, the recommended Git strategy is to rebase. Rebasing incorporates changes from one branch into another and results in a cleaner, linear project history. Merging is another option, but it can create unnecessary merge commits. Cherry-pick and reset are not typically used for this scenario.
To remove a file from the staging area without deleting the file itself, use the command git _______.
- reset
- unstage
- rm
- discard
The correct option is unstage. This command is used to remove a file from the staging area, leaving the working directory unchanged. It allows you to unstage changes that you previously staged with git add.
What is an essential step in ensuring a smooth transition from a centralized VCS to Git?
- Train team members on Git fundamentals and best practices.
- Avoid training and let the team adapt on their own.
- Perform the migration without informing the team to minimize resistance.
- Hire external consultants to handle the transition.
Training team members on Git fundamentals and best practices is essential for a smooth transition. Avoiding training may lead to confusion, and informing and involving the team in the process helps mitigate resistance. Hiring external consultants may not address the internal team's needs effectively.
During migration to Git, what is the best strategy to preserve the commit history from the previous version control system?
- Create a mapping between old and new commits, ensuring each commit is accounted for.
- Discard the old commit history for simplicity.
- Convert all old commits into a single initial commit in Git.
- Use a third-party tool to import commits directly.
When migrating to Git, it's crucial to establish a mapping between old and new commits to preserve the commit history accurately. Discarding history or converting all commits into one may result in loss of valuable information. Using third-party tools can help in importing commits seamlessly.
Reflecting on major Git successes, what is a common factor that contributes to efficient version control in large organizations?
- Centralized version control
- Frequent manual interventions
- Effective branching and merging strategies
- Avoiding the use of Git hooks
Efficient branching and merging strategies contribute to successful version control in large organizations. They enable parallel development, easy collaboration, and streamlined integration of features.
