A. Only the default VLANs are configured on SwitchA.
B. SwitchA does not have a VTP domain name configured.
C. VTP pruning needs to be enabled on SwitchA.
D. SwitchC needs to have the VTP domain name configured.

（牛头不对马嘴）正确的是：Refer to the exhibit. The three Catalyst 2950 switches have been configured for VTP.Trunking is properly configured and operational on all three switches.The show vlan command issued on Switches C displays only the default VLANs.Based on the output from the show vtp status commands shown in the exhibit,why is this true?

QUESTION 234
When two hosts are trying to communicate across a network, how does the host originating thecommunication determine the hardware address of the host that it wants to "talk" to?
A. RARP request
B. Show Network Address request
7 n( l8 ^! S8 z! F: ^C. Proxy ARP request
D. ARP request
- g( G0 K7 |  g9 J6 F/ nE. Show Hardware Address request

C. disabled

E. listening
/ z- ~* U# b, Z. {' SAnswer: AD（个人觉得是A和D）因为题目可能把STP做成RSTP了，从题目来看，RSTP converged 只有可能在discharging 和forwarding states，不过没discharging的选项。STP 的话，converged 了的states 是blocking 和forwarding

我们是学习啊，就是不全对才一起讨论

看了一下你说的第一题，我觉得还是可以举出反列出来，证明A，有问题，，仔细想想。

说下我的个人理解，N久以前看的了，没想到题目到现在还没变，，难怪na考烂了，，
Q136：B肯定是对的，交换机设置了端口安全，可以配置学习mac地址的个数，一旦个数有了，就不会再学习了，A的话，自动学习mac后过一段时间会刷新的，刷新完又了空间就可以继续接受新设备了
  k& `6 B5 c  }# T1 U- ~- u" ~Q177：配置vtp的话，需要两个参数，一个是vtp mode，一个是vtp domain name，缺少domain name，不会转发vlan信息
1 w- r7 ~- i3 O# zQ234：关键词是物理地址，arp就是解析mac地址进行通信的
下边的貌似没什么问题了，个人浅见，祝考试顺利，good luck~~~

234题 题库答案是对的。
2 n( H0 T9 Z/ X/ g( d8 h: Z, j' C5 q楼主肯定是考虑到arp request 包是广播包 无法穿越路由器。
1 {9 ^' J7 g# u但值得思考的是，主机访问不同网段的其他主机时，使用的是默认网关。需要获取的是网关MAC地址。
