Which of the following would most likely be used in a small office environment?

A print server, while useful, implies a dedicated server and is not as fundamental to the basic networking structure as a workgroup in a small office.

Virtualization is a technology for running multiple operating systems on one physical machine, which can be used in small offices but is not the primary networking model.

Domain access implies a Microsoft Active Directory domain, which requires a domain controller and is typically found in larger business environments, not small offices.

A workgroup is a peer-to-peer network model commonly used in small office or home environments where centralized authentication and management through a domain controller are not required or desired. It allows computers to share resources directly with each other.
