Which of the following configurations is used to logically segregate computers that are physically connected to the same network?

A WLAN (Wireless Local Area Network) refers to a wireless network that allows devices to connect and communicate wirelessly within a specific area. While it facilitates networking among devices, it does not provide logical segmentation, which is the primary function of a VLAN. Thus, WLANs focus on the medium of connection rather than logical separation.

A VPN (Virtual Private Network) is a technology that creates a secure connection over the internet, allowing remote users to access a private network as if they were physically present. While it enhances security and privacy for users accessing networks remotely, it does not relate to the logical segregation of computers within the same local network.

A MAN (Metropolitan Area Network) is a network that spans a city or a large campus, connecting multiple LANs. While it facilitates connectivity over broader distances, it does not offer the logical segregation functionality within a single network that VLANs provide. MANs focus on the geographic scope rather than network segmentation.
