The adminsitrator has properly configured switch interfaces FastEthernet0/13 through FastEthernet0/24 to be members of the new VLAN. However, after the network administrator completed the configuration, host A could communicate with host B, but hos A could not communicate with host C or host D. Which commands are required to resolve this problem?

A. Router(config)# interfaace fastethernet 0/1.3

Router(config-if)# encapsulation dot1q 3

Router(config-if)# ip address 192.168.3.1 255.255.255.0

B. Router(config)# router rip

Router(config-router)# network 192.168.1.0

Router(config-router)# network 192.168.2.0

Router(config-router)# network 192.168.3.0

C. Switch1# vlan database

Switch1(vlan)# vtp v2-mode

Switch1(vlan)# vtp domain cisco

Correct A

Explaination:

The reason that the newly-added VLAN3 could not communicate with other VLAN members is that no Lauer 3 route exits. To sove this problem, configure an interface on the router fo VLAN3, an IP address for the interface.
