Refer to the exhibit. What commands must be configured on the 2950 switch and the router to
allow communication between host 1 and host 2? (Choose two.)

A.
Switch1(config)# interface fastethernet 0/1Switch1(config-if)# switchport mode trunk

B.
Router(config)# interface fastethernet 0/0Router(config-if)# ip address 192.168.1.1

C.

Explanation:
In this exhibit, there are two different VLANs (VLAN 10 and VLAN 20). In this case, the router is
required for Inter-VLAN routing. In order to properly configure Inter-VLAN Routing, we need to
assign the IP address and the encapsulation type. In the router we need two sub-interfaces
created we need to assign the IP as well as defined the encapsulation type for each of these. In

the switch, only a trunk port can carry the information of multiple VLANs so fa0/1 is trunked on the
switch as shown by answer E.
