Network architecture design

A network engineer is planning a Layer 2 deployment for a company that occupies multiple floors in an office building. The engineer chooses to assign each floor to its own VLAN while still permitting communication among all user VLANs. The engineer also wants to shorten the STP convergence time when new switches come online. Which of the following should the engineer enable to achieve this goal?

Explanation

STP PortFast moves an enabled interface to the forwarding state immediately, bypassing the normal listening and learning states and avoiding the standard STP forwarding delay. It is normally used on edge ports connected to end devices; BPDU Guard provides loop-protection behavior, bridge priority selects the root bridge, and VLAN tagging identifies VLAN traffic.
