Selected Answer: C

Spanning-tree PortFast is used on switch ports that connect to end devices like PCs to immediately transition the port to the forwarding state, bypassing the usual listening and learning states. This reduces the delay in forwarding traffic, which is crucial for WoL magic packets to reach the PCs promptly.
