The 'Git Pull' command is essential for collaborative development. It allows a user to fetch changes from a remote repository and integrate them into the local branch. This is crucial for keeping the local branch up-to-date with the latest changes made by collaborators. Using 'Git Pull' helps in avoiding conflicts and ensures a smooth collaborative development process. Understanding this command is fundamental for team-based Git workflows.

When you accidentally commit to the wrong branch, you can use git rebase to move the commit to the correct branch. This interactive rebase allows you to pick, edit, or squash commits, providing flexibility in rearranging your commit history.

By using Git commit signing, the team member can ensure that their code changes are authenticated. This involves signing each commit with a cryptographic signature, providing traceability and verifying the authenticity of the changes, which is essential for security compliance.

After finding the project's repository, the first step is to fork it. Forking creates a personal copy of the repository where the developer can make changes without affecting the original project. Cloning is an option but is not the first step when contributing to open source. Creating a new branch is typically done after forking, and submitting a pull request comes later in the process.

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.

In open source projects, the Forking Workflow is commonly used. Contributors fork the main repository, create a branch for their changes, and then submit a pull request. This allows for a decentralized collaboration model.

Git LFS doesn't store the actual binary files in the repository; instead, it stores pointers to them. This helps manage large files more efficiently without bloating the Git repository.

The correct option is hard. The git reset --hard command resets the current branch and working directory to the specified commit. This option discards all changes, so use it with caution.

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.

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.
