V11的123题到底是BD还是CD啊？？？？？？急！！！！
123. Refer to the exhibit. The network shown in the exhibit is running the RIPv2 routing protocol. The network
has converged, and the routers in this network are functioning properly. The FastEthernet0/0 interface on R1 goes
down. In which two ways will the routers in this network respond to this change? (Choose two.)  

A. All routers will reference their topology database to determine if any backup routes to the 192.168.1.0 network
are known.  
B. Routers R2 and R3 mark the route as inaccessible and will not accept any further routing **s ** R1 until
their hold-down timers expire.  
C. Because of the split-horizon rule, router R2 will be prevented ** sending erroneous information to R1 about
connectivity to the 192.168.1.0 network.  
D. When router R2 learns ** R1 that the link to the 192.168.1.0 network has been lost, R2 will respond by
sending a route back to R1 with an infinite metric to the 192.168.1.0 network.  
E. R1 will send LSAs to R2 and R3 informing them of this change, and then all routers will send periodic **s
at an increased rate until the network again converges.

水平分割是肯定要选的。。。split-horizon
水平分割是C。。。
所以应该是CD咯～～～

V11里的答案是CD，可是很多人考完说答案应该是BD，不是CD。。。。。

到底是哪个啊？后天就要考了~~~~~~~~~~

可是R2会向R1发送的中毒逆转,这是破坏水平分割原则的，不理会水平分割

所以我选择BD

好

不过上次看有人说 选CD，然后1000分PASS。
所以我也不知道为什么
希望高手解答....

万分感谢

现在不是你选什么~而是Cisco要我们选什么的问题了~~

好

其实一道题目关系不大

只是怕有人运气不好...正好就差这一题没过...

選擇メ你喜歡

考试的时候还是按考试的规矩吧!

找出来修好

BD，我考了过了。。
