A network engineer is setting up a network for a company. There is a BYOD policy for the
employees so that they can connect their laptops and mobile devices.
Which of the following technologies should be employed to separate the administrative network
from the network in which all of the employees’ devices are connected?

A.
VPN

B.
VLAN

C.
WPA2

D.

same VLAN occur without hindrance, but communications between VLANs require a routing
function.
