NEW QUESTION # 41
To prevent loops on an STP network, after a designated port is elected, it must wait for a long time and can forward packets only after the status of all ports on the entire network is determined. To solve this problem, RSTP uses the P/A mechanism to speed up the downstream port's transition to the Forwarding state.

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation:
* Spanning Tree Protocol (STP) has long convergence times due to Listening and Learning states.
* Rapid Spanning Tree Protocol (RSTP) introduces:
* Proposal/Agreement (P/A) mechanism # Allows ports to quickly transition to Forwarding state without waiting.
* This mechanism significantly reduces convergence time in a switched network.
* Since RSTP does use the P/A mechanism to accelerate port forwarding, the statement is true.
# Reference: Huawei HCIA-Datacom Study Guide, STP vs. RSTP and P/A Mechanism.
