Which protocol would be utilized for file sharing among Apple devices?

The correct answer is AFP, which stands for Apple Filing Protocol. This protocol is specifically designed to facilitate file sharing among Apple devices, enabling users to connect to other Apple computers and access shared files over a network.

AFP allows users to browse files and directories on remote machines just as they would on their own devices, providing a seamless experience for managing files across different Apple systems. It includes various functions such as authentication, file locking, and support for resource forks and metadata that are particularly important for the Mac file system.

While the other protocols mentioned may have their own specialized functions, they do not specifically cater to the unique requirements of file sharing among Apple devices like AFP does. Thus, AFP stands out as the preferred choice for users within the Apple ecosystem looking to share files efficiently across their devices.
