A training class is being held in an auditorium. Hard-wired connections are required for all laptops that will be used. 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.
