Which spanning-tree enhancement avoids the learning and listening states and immediately places ports in the forwarding state?

1. A. BPDUfilter
2. B. PortFast
3. C. Backbonefast
4. D. BPDUguard

Correct Answer: B
PortFast
Spanning Tree Portfast causes layer 2 switch interfaces to enter forwarding state immediately, bypassing the listening and learning states. It should be used on ports connected directly to end hosts like servers or workstations. Note: If portfast isn’t enabled, DHCP timeouts can occur while STP converges, causing more problems.
