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. R1(config)#interface FastEthernet 0/1
R1(config-if)#switchport mode trunk
R1(config-if)#switchport access vlan 10
R1(config-if)#switchport aux vlan 100
R1(config-if)#spanning-tree port-priority
B. R1(config)#interface FastEthernet 0/1
R1(config-if)#switchport mode access
R1(config-if)#switchport native vlan 10
R1(config-if)#switchport aux vlan 100
R1(config-if)#spanning-tree portfast bpdu filter default
C. R1(config)#interface FastEthernet 0/1
R1(config-if)#switchport mode trunk
R1(config-if)#switchport native vlan 10
R1(config-if)#switchport voice vlan 100
R1(config-if)#spanning-tree portfast
D. R1(config)#interface FastEthernet 0/1
R1(config-if)#switchport mode access
R1(config-if)#switchport access vlan 10
R1(config-if)#switchport voice vlan 100
R1(config-if)#spanning-tree portfast
