A training class is being held in an auditorium. Hard-wired connections are required for all laptops that will beused. The network technician must add a switch to the room through which the laptops will connect for full
network access. Which of the following must the technician configure on a switch port, for both switches, in
order to create this setup?

A.
DHCP

B.
Split horizon

C.
CIDR

D.
TRUNK

Explanation:
We should use trunk ports to set up a VLAN for the laptops that will be used in the auditorium.
A trunk port is a port that is assigned to carry traffic for all the VLANs that are accessible by a specific switch, a
process known as trunking. Trunk ports mark frames with unique identifying tags – either 802.1Q tags or
Interswitch Link (ISL) tags – as they move between switches. Therefore, every single frame can be directed to
its designated VLAN.
