A developer accidentally committed a file that should not be tracked by Git. What command should they use to rectify this before pushing?
- git reset HEAD
- git rm --cached
- git checkout -- filename
- git revert
The correct option is c. git checkout -- filename. This command discards changes in the working directory and unstages the file, effectively "uncommitting" it. git reset HEAD and git rm --cached are used for different purposes. git reset HEAD unstages changes, and git rm --cached unstages the file but also stages the removal. git revert is used to create a new commit that undoes a previous commit.
In what scenario might you use a git filter-branch?
- Restructuring the commit history
- Updating remote branches
- Resolving merge conflicts
- Renaming a local branch
The git filter-branch command is used to rewrite, restructure, or filter the commit history. It can be useful when you need to make substantial changes to the history, such as removing sensitive information or restructuring the commit tree.
To save changes in Git, first stage them using git _______, then commit using git commit.
- add
- commit
- stage
- push
In Git, the command to stage changes before committing is git add. This command adds changes from the working directory to the staging area, allowing you to include them in the next commit.
How does integrating a code quality tool in the Git workflow enhance the development process?
- Identifies and addresses code issues early in the development cycle, improving overall code quality.
- Slows down the development process with unnecessary checks.
- Increases the number of commits without providing any tangible benefits.
- Code quality tools have no impact on the development process.
Integrating a code quality tool in the Git workflow helps identify and address code issues early, contributing to improved overall code quality. It does not slow down the process when configured properly but enhances it by catching issues before they become more complex.
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.
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.
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.
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.
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 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.
