Which type of network allows for logical segmentation of device traffic?

The correct answer is VLANs, which stands for Virtual Local Area Networks. VLANs are specifically designed to allow for the logical segmentation of network traffic within the same physical network infrastructure. This segmentation enables devices on different VLANs to operate as if they are on separate networks, even if they are physically connected to the same hardware.

The ability to create different VLANs means that network administrators can group devices by function, department, or application, which can improve performance, enhance security, and provide more efficient management. For example, one VLAN might be used for all VoIP devices, while another is dedicated to employee workstations, reducing unnecessary broadcast traffic across the entire network.

This logical separation does not require separate cabling or physical infrastructure but utilizes tagging protocols to keep the traffic distinct. It provides both flexibility and control within a network, allowing for easier changes and implementation of policies without needing changes in physical cabling.

In contrast, the other types mentioned do not provide this specific capability of logical traffic segmentation. Wireless LANs relate to wireless networking but do not inherently offer logical segmentation features. Site-to-site refers to a type of connection between two distinct networks, and DSL (Digital Subscriber Line) is a technology for providing internet connections rather than for segmenting network
