Select the correct definition of a VLAN:

A VLAN, or Virtual Local Area Network, is defined as a method to create multiple logical networks on a single physical network. This organization allows network administrators to segment a larger network into multiple virtual networks, enabling better management, increased security, and reduced broadcast traffic. By grouping devices into VLANs regardless of their physical location, it becomes possible to control traffic flow and improve the overall efficiency of the network.

The concept of VLANs is integral to modern networking, as it allows for enhanced organization within networking devices without necessarily requiring additional hardware or cabling. For example, different departments within an organization can be assigned to distinct VLANs even if the devices are physically connected to the same switch. This logical separation enhances security by limiting the scope of broadcast domains and restricting communication between different VLANs unless explicitly allowed through routing configurations.

The other choices do not accurately capture the essence of what a VLAN is designed to accomplish in a networked environment. A VLAN is specifically about logical network segmentation, rather than physical aspects of networking or traffic management protocols.
