In the context of Git, what does the term 'merge conflict' specifically refer to?
- Combining changes from multiple branches that do not conflict
- An error that occurs when attempting to merge unrelated branches
- A situation where Git cannot automatically reconcile differences between branches
- Merging branches with a linear commit history
In the context of Git, the term 'merge conflict' specifically refers to a situation where Git cannot automatically reconcile differences between branches. This occurs when changes in one branch conflict with changes in another, and Git needs manual intervention to resolve the conflicting edits. It is essential to understand how to navigate and resolve merge conflicts to maintain a clean and consistent version history in collaborative development environments. The other options describe scenarios that do not precisely define a merge conflict in Git.
How does Git handle code reviews differently from traditional version control systems?
- Integrated code review tools
- Manual code reviews through email
- No support for code reviews
- Automatic code reviews during commit
Git integrates code review tools directly into the workflow. This allows for seamless collaboration, with developers able to comment on specific lines of code, suggest changes, and ensure code quality before merging.
In complex projects, maintaining a clean history can involve the use of git rebase -i, which stands for interactive ________.
- iteration
- interface
- indexing
- rebase
The correct option is (d) rebase. The command git rebase -i allows for interactive rebasing, providing a powerful interface to modify commit history. This is particularly useful for rearranging, editing, or combining commits to maintain a cleaner project history.
When would you use git checkout instead of git reset to undo changes?
- git checkout is used for switching branches
- git checkout discards changes in the working directory
- git reset is used for switching branches
- git reset discards changes in the working directory
The correct option is git checkout. It is used to discard changes in the working directory by replacing them with the last committed version. On the other hand, git reset is more commonly used for moving the branch pointer and can be more powerful, potentially discarding commits. git checkout is a safer option for simply undoing changes in the working directory.
How does Git enable better handling of changes and revisions in large-scale projects?
- Distributed version control
- Enhanced branching and merging capabilities
- Efficient handling of complex projects
- Improved commit tracking
Git facilitates better handling of changes in large-scale projects by efficiently handling complex projects, providing enhanced branching and merging capabilities, and offering distributed version control.
How does Git enable version control for database schema changes?
- By creating separate branches for each database schema version.
- By using Git hooks to automate schema change tracking.
- By committing SQL scripts along with code changes.
- By leveraging Git tags for database schema versions.
Git helps in version controlling database schema changes by allowing developers to commit SQL scripts along with their code changes. This ensures that changes to the database schema are tracked and can be reverted if necessary.
To handle large files during a Git transition, the use of git _______ can be a solution.
- annex
- bigfile
- lfs
- compress
The correct option is 'lfs.' In Git, Large File Storage (LFS) is a system designed to handle large files efficiently. By using the 'git lfs' command, large files can be managed separately, preventing them from bloating the repository and slowing down the version control system.
GitLab’s CI/CD pipelines can be configured through a file named _________.
- .gitlab-pipeline.yml
- .gitlab-ci.yml
- .gitlab-pipe.yml
- .gitlab-config.yml
The .gitlab-ci.yml file is used to define CI/CD pipelines in GitLab. It specifies the steps and actions to be taken during the pipeline execution, such as building, testing, and deploying.
To undo changes made to your working directory, use the command git _______.
- reset
- revert
- restore
- rollback
The correct option is "b) revert." The git revert command is used to undo changes made in the working directory by creating a new commit that undoes the specified commit. This allows you to maintain a linear project history.
What is the purpose of the git bisect command in debugging?
- Efficiently find the commit introducing a bug
- Merge branches in Git
- Rewrite commit history
- View differences between branches
The git bisect command is used for binary search through commit history, helping identify the specific commit that introduced a bug by efficiently narrowing down the range of potentially faulty commits.
Git's __________ feature allows users to record changes to the repository without affecting the working directory.
- Stash
- Amend
- Commit
- Checkout
The correct option is "Stash." Git's Stash feature allows users to save changes in a "stash" without committing them, providing a way to record changes without affecting the working directory.
In Agile development, Git's ________ helps in maintaining a sustainable pace of development by isolating work in progress.
- Branching
- Stashing
- Merging
- Rebasing
In Agile development, branching in Git allows developers to isolate work on a particular feature or bug fix. This isolation enables a sustainable pace of development by keeping the main codebase unaffected until the feature is complete and ready for integration.
