下面关于用户访问部分的叙述中,正确的是( )。

- A.无线接入点与S2相连,可提高WLAN用户的访问速率
- B.有线用户以相同的代价访问Internet和服务器,设计恰当合理
- C.可增加接入层交换机向上的冗余连接,提高有线用户访问的可靠性
- D.无线接入点应放置于接入层,以提高整个网络的安全性
正确答案及解析
正确答案
解析
本题考查接入层网络部署的基本知识。
网络接入层的作用是为用户提供接入到网络的接口,无线网络接入点为无线用户提供网络的接入,一般的部署方式是将无线网络接入点放置于网络接入层设备,在拓扑设计中,将无线接入点与核心层设备 S2相连是不合理的。由于核心层设备为采用冗余连接,因此两端的用户在访问内部服务器时的代价是不同的,同时,即使在接入层添加到核心层的冗余连接,也并不能提高有线网络用户访问内部网络的可靠性,因此该项设计不恰当。
