1． Which two statements are true about the command ip route 172.16.3.0 255.255.255.0 192.168.2.4? (Choose two.)
A. It establishes a static route to the 172.16.3.0 network.
B. It establishes a static route to the 192.168.2.0 network.
C. It configures the router to send any traffic for an unknown destination to the 172.16.3.0 network.
D. It configures the router to send any traffic for an unknown destination out the interface with the address 192.168.2.4.
E. It uses the default administrative distance.
F. It is a route that would be used last if other routes to the same destination exist.
Answer: AE
解释一下：命令ip route 172.16.3.0 255.255.255.0 192.168.2.4是静态指定一条路由：通过接口192.168.2.4可以到达网段172.16.3.0/24。在这条命令后没有指定管理距离，就表示使用默认的管理距离，为1

A. Configure the gateway on Host A as 10.1.1.1.
B. Configure the gateway on Host B as 10.1.2.254.
C. Configure the IP address of Host A as 10.1.2.2.
D. Configure the IP address of Host B as 10.1.2.2.
E. Configure the masks on both hosts to be 255.255.255.224.
F. Configure the masks on both hosts to be 255.255.255.240.
Answer: BD
解释一下：主机A到他的指定网关的这条链路是没有问题的，因为HOST A，接口VLAN1和路由器的f0/0.1网段是相同的，且都是处于VLAN 1的。而HOST B的VLAN2到交换机是没有相同的VLAN 接口和他通讯的，所以HOST B发出的数据到交换机上就被丢弃了。所以需要在交换机上指定一个处于VLAN 2的接口，并将SVI地址配置为和路由器POP的f0/0.2相同网段的地址。因为路由器的接口的地址分配的是网段10.1.2.0/24，所以我们的HOST B的地址应该也分派一个10.1.2.0/24的地址，并且网关也指定为路由器POP的f0/0.2的地址。本帖隐藏的内容需要回复才可以浏览
