Show answer & explanation
Correct answer: D
Correct answer: Segmenting a network inside a switch or device.
A VLAN (Virtual Local Area Network) divides one physical switched network into separate logical broadcast domains. Devices in different VLANs behave as if they are on separate LANs, even if they are connected to the same switch.
Why this is the primary purpose: VLANs reduce unnecessary broadcast traffic and help isolate groups of users, departments, or services.
What it is not: A VLAN is not mainly a simulation tool, a physical layout diagram, or a VPN. A VPN creates encrypted remote/private connectivity, while a VLAN creates logical segmentation inside a switched network.
