How does an edge port behave in RSTP?

• A. It delays entering the Forwarding state
• B. It can become Forwarding from the Disable state instantly
• C. It must process BPDUs before transitioning
• D. It can only respond to neighbor requests

Answer: (B)

In the context of Rapid Spanning Tree Protocol (RSTP), an edge port has a distinct behavior that sets it apart from other types of ports in a bridge or switch. One of the key features of an edge port is its ability to transition directly to the Forwarding state from the Disable state without the need for a delay or intermediate states, which is significant for quick network recovery and efficient data transmission. When an edge port is configured, it implies that the port is connected to a device that is not participating in the spanning tree topology, such as a host or a computer. This classification allows the port to bypass the traditional listening and learning phases of normal port states, enabling it to become active more swiftly. As a result, the port can immediately begin forwarding traffic, leading to quicker convergence and reduced latency in the network. This capability is particularly beneficial in environments where rapid connections and disconnections occur, as it minimizes the time that devices spend waiting for spanning tree protocol calculations. The other options describe behaviors or requirements that do not apply to edge ports in RSTP. For instance, edge ports do not process Bridge Protocol Data Units (BPDUs) in the way that non-edge ports do, nor do they experience delays in moving to the Forward
