Your team is reviewing a complex set of changes. How can you use Git to navigate through each change individually to discuss them?

  • git log -p
  • git diff
  • git blame
  • git bisect
To navigate through each change individually and discuss them, you can use git log -p to show the commit history with the associated changes. git diff shows the changes in the working directory, but it's not specific to individual commits. git blame is used to show changes in a file, and git bisect is used for binary search to find a specific commit causing an issue.

How can you find a commit in the Git history that introduced a bug using the git bisect command?

  • git log -S
  • git bisect start
  • git blame
  • git revert
The correct option is B. git bisect start is used to perform a binary search through the commit history, helping identify the commit that introduced a bug. The bisect command automates the process of checking out different commits until the problematic one is found.

The command git _______ is used to clone a remote repository to your local machine.

  • pull
  • fetch
  • clone
  • push
The git clone command is used to clone a remote repository to your local machine. It copies the entire repository, including all branches and commit history, to your local system.

_________ in Git can be automated in an IDE to ensure code quality before commits.

  • Code Signing
  • Code Linting
  • Code Obfuscation
  • Code Encryption
Code linting in Git can be automated in an IDE to ensure code quality before commits. Linting checks the code for potential errors, stylistic issues, and adherence to coding standards, helping developers catch and fix issues early in the development process.

Describe the role of 'feature branches' in Git's branching model.

  • Long-lived branches for ongoing features
  • Temporary branches for hotfixes
  • Branches for experimental changes
  • Short-lived branches for documentation
'Feature branches' are long-lived branches created for ongoing features or tasks. They allow developers to work on features independently and then integrate them back into the main branch when ready. This promotes a clean and organized development process.

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.

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.
