思科的专家们，帮我看看这个na的题

来源：百度知道 编辑：UC知道 时间：2024/06/30 12:50:19
A network associate is trying to understand the operation of the FLD Corporation by studying the network in the exhibit. The associate knows that the server in VLAN 4 provides the necessary resources to support the user hosts in the other VLANs. The associate needs to determine which interfaces are access ports. Which interfaces are access ports? (Choose three.)

A. Switch1 - Fa 0/2
B. Switch1 - Fa 0/9
C. Switch2 - Fa 0/3
D. Switch2 - Fa 0/4
E. Switch2 - Fa 0/8
F. Router - Fa 1/0
ans: ACD

如题，相信专家都难看懂，就不翻译了，图也放上来了，请详细的解释，谢了。

如题所示，位于VLAN4里的服务器要为其他VLAN的用户提供资源。
说明VLAN4和其他VLAN是互通的，也就是这里的路由器要提供“单臂路由”的功能了
所以，switch1和路由器之间的接口是trunk口，switch1和switch2之间的接口也是trunk口，使用排除法，答案就是ACD了
当然，也可以根据将计算机划分到VLAN里，那么连接计算机的端口应该的access口，即Fa 0/2 ,Fa 0/3 ,Fa 0/4 , Fa 0/5 ,Fa 0/6都是access口
