Which Rapid PVST+ feature should be enabled on a switch port to forward immediately when a connected server link becomes active?

PortFast immediately transitions a switch port to the forwarding state, bypassing the normal Spanning Tree Protocol (STP) listening and learning states. This is ideal for ports connected to end devices like servers, as it eliminates the 30-50 second delay before the device can communicate on the network, improving boot-up times and application availability. UplinkFast is a Cisco proprietary feature designed to speed up convergence when a direct link to the root bridge fails, primarily for switches with redundant links. It's not for end-device connections. BPDU Guard disables a port if it receives a Bridge Protocol Data Unit (BPDU), preventing unauthorized switches from interfering with STP, which is a security feature, not a speed optimization. Loop Guard prevents alternate or root ports from becoming designated ports in the event of a unidirectional link failure, which helps prevent loops but doesn't speed up initial port activation.
