You need to configure a new IOS-based Catalyst switch to support voice and data VLANs. The
data VLAN will be VLAN 10 and the voice VLAN will be VLAN 100. Which of the following
configurations should be used to support these VLANs while also allowing switch port 0/1 to enter
the forwarding state immediately?

A.
R 1(config)# interface FastEthernet 0/1
R 1(config-if)# switchport mode trunk
R 1(config-if)# switchport access vlan 10
R 1(config-if)# switchport aux vlan 100
R 1(config-if)# spanning-tree port-priority

B.
R 1(config)# interface FastEthernet 0/1
R 1(config-if)# switchport mode access
R 1(config-if)# switchport native vlan 10
R 1(config-if)# switchport aux vlan 100
R 1(config-if)# spanning-tree portfast bpdu filter default

C.
R 1(config)# interface FastEthernet 0/1
R 1(config-if)# switchport mode trunk
R 1(config-if)# switchport native vlan 10
R 1(config-if)# switchport voice vlan 100
R 1(config-if)# spanning-tree portfast

D.
R 1(config)# interface FastEthernet 0/1
R 1(config-if)# switchport mode access

R 1(config-if)# switchport access vlan 10
R 1(config-if)# switchport voice vlan 100
R 1(config-if)# spanning-tree portfast
