Refer to the exhibit.

How should the FastEthernet0/1 ports on the 2950 model switches that are shown in the exhibit be
configured to allow connectivity between all devices?

A.
The ports only need to be connected by a crossover cable.

B.
SwitchX(config)# interface fastethernet 0/1
SwitchX(config-if)# switchport mode trunk

C.
SwitchX(config)# interface fastethernet 0/1
SwitchX(config-if)# switchport mode access
SwitchX(config-if)# switchport access vlan 1

D.
SwitchX(config)# interface fastethernet 0/1
SwitchX(config-if)# switchport mode trunk
SwitchX(config-if)# switchport trunk vlan 1
SwitchX(config-if)# switchport trunk vlan 10
SwitchX(config-if)# switchport trunk vlan 20

Explanation:
IN order for multiple VLANs to cross switches, the connection between the switches must be a
trunk. The “switchport mode trunk” command is all that is needed, the individual VLANs should not
be listed over that trunk interface.
