A technician wants to separate networks on a switch. Which of the following should be configured
to allow this?

A.
VLAN

B.
Trunking

C.
Spanning tree

D.
Traffic filtering

Explanation:
A VLAN is a group of end stations in a switched network that is logically segmented by function,
project team, or application, without regard to the physical locations of the users. VLANs have the
same attributes as physical LANs, but you can group end stations even if they are not physically
located on the same LAN segment.
