Refer to the exhibit. Configuration of both switches has been completed. During testing, the
network administrator notices that users on SwitchA can not connect with users in the same VLAN
on SwitchB. What should be done to solve this problem?

A.
Ensure that the IP address of SwitchA is on the same network as the IP address of SwitchB.

B.
Ensure that the same interface number is used to connect both switches.

C.
Ensure that the ports connecting the two switches are configured to trunk.

D.
Ensure that SwitchA and SwitchB are connected with a straight-through cable.

Explanation:
Ports can be in two states on a switch:
Access ports: This type of link is only part of one VLAN, and it’s referred to as the native VLAN of
the port. Any device attached to an access link is unaware of a VLAN membership the device just
assumes it’s part of a broadcast domain, but it does not understand the physical network.
Trunk links: Trunks can carry multiple VLANs and originally gained their name after the telephone
system trunks that carry multiple telephone conversations.
So to carry the VLAN information from one switch to another switch, a trunk link needs to be
configured between the two switches, using the “showtchport mode trunk” command.
Note: By default all ports are in access mode.
