Refer to the exhibit. Rapid PVST+ is enabled on all switches. Which command set must be configured on Switch1 to achieve the following results on port fa0/1?

• When a device is connected, the port transitions immediately to a forwarding state.
• The interface should not send or receive BPDUs.
• If a BPDU is received, it continues operating normally.

A. 
Switch1(config)# interface f0/1
Switch1(config-if)# spanning-tree portfast
Switch1(config-if)# spanning-tree bpduguard enable

B. 
Switch1(config)# spanning-tree portfast bpduguard default
Switch1(config)# interface f0/1
Switch1(config-if)# spanning-tree portfast

C. 
Switch1(config)#interface f0/1
Switch1(config-if)# spanning-tree portfast

D. 
Switch1(config)#spanning-tree portfast bpdufilter default
Switch1(config)# interface f0/1
Switch1(config-if)# spanning-tree portfast

Correct Answer: D

BPDU filtering allows you to avoid transmitting BPDUs on PortFast-enabled ports that are connected to an end system. When you enable PortFast on the switch, spanning tree places ports in the forwarding state immediately, instead of going through the listening, learning, and forwarding states.
