In large projects, what Git feature is essential for managing multiple features being developed simultaneously?
- Branching
- Merging
- Stashing
- Rebasing
Managing Multiple Features in Git
To automate builds after every commit, a hook in Git known as git _______ can be used.
- pre-commit
- post-commit
- pre-build
- post-build
In Git, the post-commit hook is used to automate actions after each commit. This hook is useful for tasks like triggering build processes.
git _______ can be used to combine the changes made on two different branches without creating a new commit.
- merge
- squash
- rebase
- commit
Git rebase allows you to incorporate changes from one branch into another by applying each commit on the branch to the target branch. Unlike merge, it allows for a cleaner commit history by avoiding unnecessary merge commits.
What are the benefits of using a Git Subtree over a Submodule?
- Easier to maintain and update
- Can include a single directory from a repository
- Provides more isolation
- Supports nested subprojects
One benefit of using a Git Subtree over a Submodule is that it allows you to include a single directory from a repository, making it more flexible and granular. This can be useful when you only need a specific part of another project.
A company uses Git for both application code and database version control. How should they structure their repositories to manage changes effectively?
- Single Repository with Multiple Folders for Code and Database
- Separate Repositories for Code and Database
- Git Submodules
- Git Subtrees
The company should use Separate Repositories for Code and Database. This approach provides clear separation between application code and database version control. Each repository can have its own history, branches, and releases, making it easier to manage changes independently. It also helps in maintaining a clean and focused history for each component, facilitating collaboration and version control for both application code and the database.
To prevent accidental commits of confidential data, Git can use a pre-commit ________.
- hooks
- filters
- validations
- scripts
In Git, pre-commit hooks allow you to perform actions or checks before a commit is completed. They are often used to prevent committing sensitive data, making "hooks" the correct term in this context.
How does Git track changes within a repository?
- Through file timestamps
- By creating snapshots of the changes
- Using file checksums for changes
- Tracking changes through external logs
Git tracks changes by creating snapshots of the entire repository at different points in time. Each snapshot (commit) contains a reference to the previous snapshot, forming a chain of changes.
In a collaborative environment, a developer wants to contribute to a project they don't have write access to. What Git workflow should they follow?
- Feature Branch Workflow
- Gitflow Workflow
- Forking Workflow
- Centralized Workflow
The Forking Workflow is suitable for situations where a developer wants to contribute to a project without having direct write access. They fork the repository, create a feature branch in their fork, and then submit a pull request for the changes to be merged into the main project.
Major Git successes often highlight the importance of ________ in managing large and complex repositories.
- Efficient Branching
- Proper Commit Messages
- Git Hooks
- Collaboration and Communication
Successful Git implementations often emphasize the significance of effective collaboration and communication. Managing large and complex repositories requires teams to work cohesively, follow proper branching strategies, and communicate changes effectively. This ensures that the development process remains organized and streamlined, leading to successful outcomes in major projects.
What is the difference between git reset and git revert?
- git reset removes commits
- git reset undoes changes in the working directory
- git revert removes commits
- git revert undoes changes in the working directory
The correct option is git revert. Unlike git reset, which removes commits from the branch history, git revert creates a new commit that undoes the changes introduced by a specific commit. This ensures a safer and non-destructive way to undo changes. git reset, on the other hand, can be used to move the branch pointer and potentially discard commits.
