323.Refer to the exhibit.An organization connects two locations,supporting two VLANs,through two
switches as shown.Inter-VLANs communication is not required.The network is working properly and
there is full connectivity.The organization needs to add additional VLANs,so it has been decided to
implement VTP.Both switches are configured as VTP servers in the same VTP domain.VLANs added to
Switch1 are not learned by Switch2.Based on this information and the partial configurations in the exhibit,
what is the problem?
A.Switch2 should be configured as a VTP client.
B.VTP is Cisco proprietary and requires a different trunking encapsulation.
C.A router is required to route VTP advertisements between the switches.
D.STP has blocked one of the links between the switches,limiting connectivity.
E.The links between the switches are access links.
Answer:D （看不出他要考什么知识点,各自一个vlan,还不要求互联,就一个阻塞就完了?奇怪）
感谢一楼的回答，
是不是假如sw2的f0/2口阻塞，
那么不管在哪边加了新的vlan，总之是另一边学不来，且原来的vlan20也断了？
另外：你的意思是不是原本不加新vlan时，这个状态就是不稳定的，也要阻塞一个f0/2口。
      等stp稳定后，势必vlan20要断了？请详加指导了。这部分没学透，

这题考的其实是STP生成树协议,意思是这两条连路会自动的阻断一条,如果要解决可以把其中的一个端口设为Block状态就可以.
不加新Vlan时,这个状态就是不稳定的,也要阻塞一个.对,是要阻塞一个,不然就会在环路网络中无限循环.
先翻译一下,大致的是：
如图所示,一组织通过交换机连接了两个本地VLAN,VLAN间的通信不被允许.这个网络工作正常而且已经全连接.这个组织需要增加额外的VLAN,所以决定使用VTP协议.这两台交换机都已经配置为VTP服务器,VTP域名也相同.交换机2不能学习交换机1添加的VLAN.根据如图的基本信息和部分配置,这个问题是什么?
A.交换机2应当配成VTP客户端.
B.VTP是思科私有应当需要配置在不同的TRUNK协议.
C.一台路由器需要运行VTP通告在两台交换机之间.
D.在两台交换机之间生成树协议阻断了其中的一个连接,限制了连接性.
E.在交换机间的连接是静态访问.
这题应当是选D,因为这两台交换机没有明确那台是Server,哪台是Client,当在交换机1配置完成的时候,STP会自动的阻断一个连接,同时将环路网络修剪成无环路的树型网络,从而避免报文在环路网络中的增生和无限循环,防止形成广播风暴.
