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
B: Trunk ports are going to allow all vlans by default; adding those vlans that are in use in this environment are both incorrectly submitted (SwitchX(config-if)#switchport trunk allow vlan 1,10,20 would be correct) and unnecessary.
