What technology was originally designed to decrease broadcast traffic but is also beneficial in reducing the likelihood of having information compromised by sniffers?
A.
VPN (Virtual Private Network)
B.
DMZ (Demilitarized Zone)
C.
VLAN (Virtual Local Area Network)
D.
RADIUS (Remote Authentication Dial-in User Service)
Explanation:
A VLAN allows you to create groups of users and systems and segment them on the network. This segmentation allows you to hide segments of the network from other segments and control access. You can think of a VLAN as a good way to contain network traffic. VLANS are created by using a switch and switched networks mitigate against sniffers.
