Which of the following describes a valid use of a shared LAN?

• A. It may contain restricted files
• B. It can be used for distribution and use of electronic documents
• C. It can be used to save, edit and delete files
• D. All of the above

Answer: (D)

A shared LAN serves as a central space for storing and accessing organizational documents, enabling collaboration and resource sharing. It can distribute and be used for electronic documents because those documents live on a shared storage area that authorized users can access and work with. It also supports saving, editing, and deleting files by those users, since the shared drive or server is designed for file management with appropriate permissions. If there are restricted files, they can still exist on a shared LAN as long as access controls (permissions) are in place to limit who can view or alter them. Taken together, these describe all the typical, valid uses of a shared LAN.
