Which Git command is used to view changes made by each commit?
- git log
- git show
- git diff
- git status
The git log command is used to view the commit history of a repository. It displays information about each commit, including the commit message, author, date, and a unique identifier. This helps in understanding the changes made in each commit in chronological order.
How does Git support the automation of deployment in DevOps practices?
- Integrated Hooks for Deployment
- Git Submodules
- Git Tags
- Git Stash
Git provides integrated hooks that allow scripts to run automatically after events like commits or merges. These hooks can be leveraged to automate deployment processes in DevOps practices, making the workflow more efficient and reliable.
When preparing for a major release, what steps should be taken to ensure that all features are merged and conflicts are resolved efficiently?
- Perform a final merge of all feature branches into main
- Use a version control tool other than Git for release management
- Resolve conflicts manually to ensure accuracy
- Apply Git tags to mark the release point
Performing a final merge of all feature branches into the main branch consolidates all changes. This ensures that conflicts are identified and resolved collectively before the release. Option 2 suggests an alternative tool, which may not be necessary if Git is already in use. Option 3 is generally not recommended due to potential errors. Option 4 is about tagging releases but does not address conflict resolution directly.
What is a key challenge in implementing Git in a large, previously non-Git environment, and how is it typically addressed?
- Difficulty in transitioning existing workflows
- Resistance from team members
- Lack of version control understanding
- Integration with legacy systems
In large, non-Git environments, transitioning existing workflows to Git can be challenging due to established practices. Addressing this challenge involves providing comprehensive training and support to ease the migration process. It is essential to communicate the benefits of Git and address concerns from team members to ensure a smooth transition.
In Git, how would you manage multiple remote repositories for the same local repository?
- Use git branch
- git remote add
- git merge
- git push
The correct option is B. git remote add is used to manage multiple remote repositories. It allows you to associate a remote name with a URL and then refer to that remote with the given name. This is useful for fetching and pushing changes to different remote repositories.
During the migration to Git, a team encounters issues with large binary files slowing down the repository. What Git feature or strategy can address this issue?
- Git LFS (Large File Storage)
- Shallow Clone
- Git Submodules
- Git Cherry-Pick
Git LFS is designed to handle large binary files efficiently, addressing performance issues during migration and maintaining a streamlined repository.
During a code review, a team member notices that a commit contains a bug. What Git feature can they use to identify who made the specific changes?
- Git Blame
- Git Log
- Git Show
- Git Diff
The correct option is Git Blame, which shows the author and last modification of each line in a file. This helps identify who made specific changes in a commit.
During a project, two developers work on the same file and create conflicting changes. What is the best way to proceed after Git indicates a merge conflict?
- Manually resolve the conflict by editing the file in question.
- Discard all changes made by both developers and start from scratch.
- Accept one developer's changes over the other without reviewing.
- Use the git merge --abort command to undo the merge and resolve conflicts.
When a merge conflict occurs, Git pauses the merging process and marks the conflicted areas. The developer should manually resolve the conflict by editing the file to combine the changes. The git merge --abort command can be used to undo the merge attempt, allowing the developer to resolve conflicts and try the merge again.
If you need to review the history of changes within a specific file, use git _______ .
- log
- status
- show
- diff
The correct option is show. The git show command displays the content and changes of a specified commit or file. It is particularly useful for reviewing the history of changes within a specific file.
How can GPG (GNU Privacy Guard) be used in the context of Git?
- Sign commits with GPG
- Encrypt sensitive files
- Create Git tags
- Enable Git history tracking
GPG (GNU Privacy Guard) in Git is used to sign commits, providing a verifiable way to confirm the author's identity and the integrity of the code. This enhances security and trust in the Git repository.
