Question

A company is separating its accounting department's network from its customer service department's network. Which of the following will accomplish this task?

Options

AVPN
BDNS
CVLAN
DDHCP

Explanation

VLANs (Virtual Local Area Networks) are used to segment a single physical network switch into multiple logical, isolated networks. This allows an administrator to separate traffic from different departments (like accounting and customer service) even if the computers are connected to the same physical networking equipment, without needing to install separate physical cabling and devices. This improves security by ensuring sensitive accounting data is segregated from other network traffic.
