After a major failure in version control, an enterprise revises its Git strategy. What aspect of Git are they most likely to focus on for improvement?

  • Branching and Merging
  • Commit Strategies
  • Git Hooks
  • Git Configuration
After a version control failure, an enterprise is likely to focus on improving branching and merging strategies to prevent conflicts and enhance the overall stability of version control. Effective branching and merging are crucial for maintaining a reliable codebase.

In a distributed version control system like Git, each contributor has a local copy of the ________.

  • Branch
  • Repository
  • Staging Area
  • Working Directory
In Git, each contributor has a local copy of the repository. The repository contains the entire project history and all the branches.

What is a unique feature of GitLab compared to GitHub and Bitbucket?

  • Built-in CI/CD pipelines for automated testing and deployment.
  • Exclusive support for private repositories.
  • Integration with third-party code review tools.
  • GitLab is a version of GitHub.
GitLab provides built-in CI/CD pipelines, allowing for automated testing and deployment, which is a unique feature compared to GitHub and Bitbucket.

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.

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.

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.
