What is a feature of virtual LANs (VLANs)?
- Logical segmentation is provided by creating multiple broadcast domains on a single switch.
- A single collision domain is enabled on a switch that is shared between VLANs.
- Communication between different VLANs on the one switch is enabled by default.
- Switch port utilization is decreased because each port is only associated with one broadcast domain.
Explanation: Virtual LANs (VLANs) provide a logical segmentation by creating multiple broadcast domains on the same network switch. VLANs provide higher utilization of switch ports because a port could be associated to the necessary broadcast domain, and multiple broadcast domains can reside on the same switch. Network devices in one VLAN cannot communicate with devices in a different VLAN without the implementation of inter-VLAN routing.
