To revert to a particular commit, the command git revert ______ is used.
- commit
- revert
- reset
- restore
The correct option is "revert." When you want to revert to a particular commit in Git, you use the git revert command followed by the commit hash. This creates a new commit that undoes the changes introduced by the specified commit.
What are the best practices for using Git in a complex DevOps environment involving multiple teams and services?
- Implementing feature toggles for gradual deployment
- Using a single Git repository for all services
- Establishing a clear branching strategy
- Avoiding automated testing in the development pipeline
In a complex DevOps environment, establishing a clear branching strategy is crucial. This helps manage parallel development, integration, and release processes among multiple teams and services, ensuring a streamlined workflow.
When you want to combine histories of multiple repositories, a git __________ can be a suitable approach.
- merge
- fetch
- subtree
- clone
The correct option is subtree. Using the subtree merge strategy, you can merge a subtree of another repository into your project while maintaining the history of both repositories.
What is the main purpose of using Git Submodules?
- Code sharing between repositories
- Version control for individual files
- Merging branches
- Creating lightweight branches
Git Submodules are used for integrating external repositories as a subdirectory within a main repository. The main purpose is code sharing between repositories, allowing you to include external projects while keeping them isolated.
The git ________ command provides a byte-wise comparison between two branches to diagnose corruption or discrepancies.
- git diff
- git compare
- git diagnose
- git verify
The correct option is git diff. This command is used to show the differences between two branches at a byte level, making it useful for diagnosing corruption or discrepancies in the branches.
What is a pull request in the context of Git?
- A way to request someone to pull your changes
- A command to pull the latest changes from the remote repository
- A request to merge two branches
- A request to undo the last commit
A pull request is a method used to propose changes to a repository. It allows collaborators to review and discuss the changes before merging them into the main branch. It typically includes details about the changes made and the reason for the changes. This is an essential part of the collaborative workflow in Git.
What is the purpose of the .gitignore file in a Git repository?
- Exclude specific files from version control
- Store sensitive data
- Track changes in the repository
- Create backups automatically
The .gitignore file is used to exclude specific files or patterns from being tracked by Git. This is helpful to avoid cluttering the repository with files that shouldn't be versioned, such as temporary files, build artifacts, or system-specific files.
When stashing changes, what happens to the staged and unstaged modifications in Git?
- Staged changes are preserved, unstaged changes are discarded
- Both staged and unstaged changes are preserved
- Staged changes are discarded, unstaged changes are preserved
- Both staged and unstaged changes are discarded
When you stash changes, Git saves both staged and unstaged changes. This allows you to switch branches without committing changes, and later apply the stash to continue working on the changes.
To delete a tag in Git, use the command git tag -d ________.
- tag-name
- git-delete
- tag-delete
- git-rm
The correct option is a) tag-name. This command deletes the specified tag by providing the tag name after the -d option. It helps in removing unnecessary or incorrect tags from the repository.
A Git Subtree allows you to keep a copy of an external repository in a subdirectory, treating it as a __________ project.
- separate
- nested
- linked
- subtree
The correct answer is subtree. Git subtree is a merging strategy that allows you to insert the contents of a repository into another one, but unlike submodules, the external repository becomes part of the history of the main repository. It is treated as a subtree within the main project.
