What is the default STP mode in modern switches?

• A. Rapid Spanning Tree Protocol
• B. Per VLAN Spanning Tree
• C. Spanning Tree Protocol
• D. Multiple Spanning Tree Protocol

Answer: (A)

The default Spanning Tree Protocol (STP) mode in modern switches is Rapid Spanning Tree Protocol (RSTP). RSTP is an evolution of the original Spanning Tree Protocol (STP) and is defined in IEEE 802.1w. It addresses some of the limitations of STP by providing faster convergence times, which means that network topology changes can be detected and recovered from more quickly. RSTP significantly reduces the time it takes to re-establish the loop-free topology after a change in the network, making it a more efficient and robust protocol for modern networking environments. While Per VLAN Spanning Tree (PVST) allows for the configuration of STP on a per-VLAN basis, and Multiple Spanning Tree Protocol (MSTP) enables mapping multiple VLANs into a single spanning tree, RSTP is generally favored by modern switches due to its improved performance and faster network recovery capabilities. The original Spanning Tree Protocol is less commonly used in contemporary networks because of its slower convergence times compared to RSTP.
