Question 25

VLAN is the configuration used to logically segregate computers that are physically connected to the same network.

A Virtual Local Area Network (VLAN) allows for the segmentation of a network into distinct broadcast domains, enabling logical separation of computers despite their physical connection to the same network infrastructure.

A) WLAN

A Wireless Local Area Network (WLAN) refers specifically to a wireless network that allows devices to connect and communicate over a wireless signal. While it facilitates connectivity, it does not provide the logical segregation of devices within a shared physical network.

B) VPN

A Virtual Private Network (VPN) creates a secure connection over the internet, allowing users to send and receive data as if their devices were directly connected to a private network. While it enhances security, it does not segregate computers on the same local network.

C) VLAN

A Virtual Local Area Network (VLAN) is designed specifically for logical segmentation of networks. It enables different groups of devices to communicate as if they are on separate networks, even though they share the same physical infrastructure, thus providing isolation and improved management.

D) MAN

A Metropolitan Area Network (MAN) connects multiple local area networks (LANs) over a larger geographic area, such as a city. It does not focus on the logical segregation of devices and is more about interconnecting networks rather than isolating them within the same physical connection.

Conclusion

VLAN is the only option that effectively provides logical segregation within the same physical network, allowing for improved organization and security. Other options, such as WLAN, VPN, and MAN, serve different purposes related to connectivity or security but do not achieve the same level of logical separation as VLAN does. Thus, VLAN is the definitive correct answer.
