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.
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.
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.
What is the best practice for securing sensitive data, like passwords, in a Git repository?
- git encrypt
- git ignore
- git filter-branch
- git-crypt
The best practice for securing sensitive data in a Git repository is to use tools like git-crypt, which encrypts and decrypts files transparently during a git clone or git pull. This ensures that sensitive information remains secure.
A critical aspect of scaling Git for enterprise is setting up efficient ________.
- commit history
- branching strategies
- authentication
- code reviews
Setting up efficient branching strategies is a critical aspect of scaling Git for enterprise. Clear and well-defined branching strategies help manage parallel development efforts, reducing conflicts and streamlining the integration process.
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.
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.
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.
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.
A common tool used in distributed teams for collaborative Git workflow management is git ________.
- hub
- flow
- team
- sync
Git hub is a command-line wrapper for Git that makes it easier to work with GitHub repositories. It provides additional features for collaborative workflows in distributed teams.
