Comprehensive and Detailed Explanation From Exact Extract:

PortFast is a feature in Spanning Tree Protocol (STP) that allows switch ports connected to end devices (like user workstations) to bypass the usual STP states (Listening and Learning) and transition immediately to the Forwarding state. This significantly reduces convergence time and speeds up the network availability when new switches or ports are introduced.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “STP Optimization Techniques”:

“PortFast reduces STP convergence time by immediately placing access ports into the forwarding state, useful in environments where rapid network availability is required.”

Other options:

A. BPDU Guard is used to disable ports that receive Bridge Protocol Data Units, enhancing security but not STP speed.

B. Priority modifies bridge priority but doesn’t reduce convergence time.

C. Tagging relates to VLAN identification, not STP behavior.
