关于STP端口状态，下列说法正确的有（）。A、当端口处于Listening状态时，会接收配置BPDU并进行计算，但是不发送配置BPDUB、当端口处于Learning状态时，开始学习MAC地址，但是不转发数据C、无论端口最终确定何种角色，在Listening状态和Learning状态停留的时间都为一个Forward Delay时长D、当端口处于Listening状态和Learning状态时，如果端口角色变为Alternate端口，则该端口状态会直接转变为Blocking

关于RSTP和STP的计算收敛的对比，说法正确的有（）。A、如果STP想缩短收敛时间，只能配置较小的Forward Delay时间，但是可能会影响到网络的稳定性B、相对于STP，RSTP定义了边缘端口，这样可以使得连接PC主机的端口快速进入转发状态C、相对于STP，RSTP定义了根端口快速切换机制，这样可以使得Alternate快速成为新的根端口D、相对于STP，RSTP定义了指定端口快速切换机制，这样可以使得指定端口快速进入转发状态而不需要等待两倍的Forward Delay时间
