Rapid Spanning Tree Protocol is faster than traditional Spanning Tree Protocol. True or False?

Explanation:
Rapid Spanning Tree Protocol speeds up convergence compared with traditional Spanning Tree Protocol. Traditional STP relies on a sequence of port states and fixed timers, so after a topology change a non-root port must go through blocking, listening, and learning before it can forward again, which can take around 30 seconds or more. RSTP changes that by introducing faster transition mechanisms: edge ports that can go directly to forwarding when connected to end devices, and new port roles (alternate and backup) with a streamlined handshake between switches. This handshake—often called a proposal/agreement process—lets ports move to forwarding much sooner, typically within a few seconds and often nearly instantly if the change occurs on a non-edge link. Because of these design changes, RSTP converges much faster than STP, so the statement is true.
