Git's _______ feature helps in managing different database environments like development, testing, and production.
- branches
- tags
- submodules
- environments
Git's environments feature allows for managing different deployment environments, making it easier to coordinate changes across development, testing, and production.
An enterprise is experiencing slow performance with their Git repositories due to large file sizes. What Git feature should they consider implementing?
- Git LFS (Large File Storage)
- Git Submodules
- Git Stash
- Git Clone
In scenarios where large files impact Git repository performance, Git LFS (Large File Storage) is a recommended solution. It allows the storage of large files outside the regular Git repository, improving overall performance by handling large files more efficiently.
What are the best practices for garbage collection in Git to optimize repository performance?
- Perform git gc regularly
- Use git prune to remove unreachable objects
- Utilize git repack to optimize storage
- Apply git fsck to check repository integrity
Garbage collection in Git helps optimize the repository's performance by compressing and organizing objects. git repack is an advanced strategy that combines objects, optimizing storage and improving performance.
Which file in a Git repository typically contains a list of files to be ignored?
- .gitignore
- .gitexclude
- .ignore
- .exclude
The file that contains a list of files to be ignored in a Git repository is .gitignore. Developers use this file to specify patterns of files and directories that should be excluded from version control.
The __________ Git Hook is executed on the client side before a push is executed.
- pre-receive
- post-receive
- pre-push
- post-commit
The correct answer is pre-push. This Git hook is triggered on the client side just before a push is executed. It allows you to check certain conditions before allowing the push operation. Common use cases include running tests or code style checks before changes are pushed to the remote repository.
When a merge conflict occurs, what does Git use to mark the conflicted area in the files?
- <<<<<<< HEAD, =======, >>>>>>> branch_name
- <<<<<<< conflict_start, =======, >>>>>>> conflict_end
- <<<<<<<, =======, >>>>>>>
- <<<<<<< HEAD, conflict_marker, >>>>>>>
When a merge conflict occurs, Git uses the conflict markers <<<<<<< HEAD, =======, and >>>>>>> branch_name to indicate the conflicting changes between the current branch (HEAD) and the branch being merged. Developers need to manually resolve these conflicts by editing the file to remove the markers and choose which changes to keep. The HEAD marker denotes the changes from the current branch, and the branch_name marker indicates the changes from the other branch.
How can you create an annotated tag in Git that includes a message?
- git tag -a
-m "Your message here" - git tag -m "Your message here"
- git tag -s
-m "Your message here" - git tag -l "Your message here" -a
Annotated tags in Git, which include a message, can be created using the command git tag -a -m "Your message here". The -a flag specifies that the tag will be annotated, and the -m flag allows you to include a message with the tag, providing additional information about the tag, such as release notes or important details related to that version.
The ________ model in Git is ideal for open-source projects where contributors do not have direct write access to the main repository.
- Forking
- Centralized
- Distributed
- Feature Branching
The forking model in Git is ideal for open-source projects where contributors do not have direct write access to the main repository. Contributors fork the main repository, make changes in their forked copies, and then create pull requests to propose changes to the main repository. This model allows for a decentralized contribution workflow, making it easier for multiple contributors to work on the project simultaneously.
To ignore file changes in your working directory, you should update the _________ file in your Git repository.
- .gitignore
- .gitconfig
- .ignore
- .exclude
The correct option is .gitignore. This file contains a list of file patterns that Git should ignore when tracking changes in your working directory. It's useful for excluding temporary files, build artifacts, and other files that shouldn't be part of your version control.
Changing the history of public branches is generally discouraged because it can lead to ________ for other collaborators.
- synchronization issues
- confusion
- conflict resolution
- frustration
The correct option is (c) conflict resolution. Altering the history of public branches can create conflicts for other collaborators, making it challenging to resolve differences in the repository. It's a good practice to avoid history changes on shared branches.
In Git, a _______ merge is used to integrate changes from one branch into another without creating a merge commit.
- Fast-Forward
- Squash
- Recursive
- Cherry-pick
The correct option is Fast-Forward. A Fast-Forward merge in Git is used to integrate changes from one branch into another when there are no new changes on the target branch. It performs a simple "move forward" of the branch pointer, avoiding the creation of a merge commit.
How can you identify the specific commits that introduced conflicting changes during a merge in Git?
- git blame
- git show
- git diff
- git log
When a merge conflict occurs, using git diff will help identify the conflicting changes introduced by specific commits. This command shows the differences between the working directory and the index or a tree, making it useful for inspecting changes.
