以下关于生成树协议的端口角色的描述不正确的是？（）A、生成树协议（STP）的端口角色有根端口（Root Port），指定端口（Designated Port）和备份端口（BackupPort）；快速生成树协议（RSTP）的端口角色有根端口（Root Port）、指定端口（Designated Port），备份端口（Backup Port）和预备端口（Alternate Port）。B、生成树协议（STP）的端口角色有根端口（Root Port），指定端口（Designated Port）和预备端口（AlternatePort）；快速生成树协议（RSTP）的端口角色有根端口（Root Port）、指定端口（Designated Port），备份端口（Backup Port）和预备端口（Alternate Port）。C、预备端口（Alternate Port）所属交换机是该端口所连接的网段的指定交换机。D、备份端口（Backup Port）所属交换机不是该端口所连接的网段的指定交换机，是RSTP特有的端口角色。
