一道CCNA的题,拜托了!
Refer to the exhibit. R1 is routing between networks 192.168.10.0/28 and 192.168.30.0/28. PC1 can ping R1 interface F0/1, but cannot ping PC3. What is causing this failure?
PC1 and PC3 are not in the same VLAN.
The PC3 network address configuration is incorrect.（正确）
The S1 interface F0/11 should be assigned to VLAN30.
The F0/0 and F0/1 interfaces on R1 must be configured as trunks.
奇怪,我明明把题贴上去,怎么没了……

1.PC1 and PC3 are not in the same VLAN.虽然两个PC处于不同vlan,但是借助三层设备可以完成vlan间的通信.路由器没设置trunk,但是有两条链路,一条走vlan10,一条走vlan30,所以这个不是不能通信的原因；
2.The PC3 network address configuration is incorrect是对的,明显PC3的网关192.168.30.1跟192.168.30.100处于不同的网段,所以通信不了.用子网掩码算一下就知道了.
3.The S1 interface F0/11 should be assigned to VLAN30.错误的,图上标明vlan10
4.The F0/0 and F0/1 interfaces on R1 must be configured as trunks.这里有两条线,不用配置trunk,每个vlan走一条链路就可以了,只有一条链路才需要.
