2012年思科认证考试备考的朋友，不用为了查找复习资料而烦恼，小编特为广大考生朋友们搜集了有关思科认证CCIE考试模拟试题，帮助大家复习，祝大家考试顺利。
31. Customer X has a hub-and-spoke Frame Relay network, with a central office and two branch offices (RemoteA and RemoteB). Each location has only one physical link to the Frame Relay cloud and RemoteB has a router that is not a Cisco router. Since the installation, there is no connectivity between RemoteB and the central office. What is a possible solution to this issue?
首先关闭这些接口
E. Fast Ethernet and Gigabit Ethernet ports cannot be assigned to the same EtherChannel.
客户X 有一个HUBSPOKED的帧中继网络来连接中心办公室和两个分支办公室（A和B） ， 每个地方有一个物理线路连接到帧中继网络，B 有一个路由器不是CISCO的，安装后不能 建立B和中心办公室之间的链接，怎么可以解决这个问题？
A. Because Frame Relay IETF encapsulation is only configurable at interface level, you must use IETF encapsulation on all routers. B. This is not a possible scenario. A dedicated Frame Relay link to RemoteB is mandatory at the central office. C. The router at RemoteB must be replaced by a Cisco router. D. Use Frame Relay IETF encapsulation on a per-VC basis on the central office router.
在中心办公室使用IETF来封装帧中继，在没有一个PVC上。
E. There is a problem in the Frame Relay cloud, because Cisco routers are compatible with IETF Frame Relay. Answer: D
32. Refer to the exhibit. There are two sites connected across WAN links. All intersite and intrasite links always have the same routing metric. The network administrator sees only the top routers and links being used by hosts at both LAN A and LAN B. What would be two suggestions to load-balance the traffic across both WAN links? (Choose two.)
如图所示，都过WAN链路连接的两个网络。所有的内部路由和内部链路的度量值都是一样 的，网络管理员发现只有上面的路由器和线路被用来连接A和B。 ，怎么做能让网络可以负载 均衡？
A. Make HSRP track interfaces between the edge and core routers. B. Replace HSRP with GLBP.
用GLBP替换HSRP
C. Add crossed intrasite links: R1-R4, R2-R3, R5-R8, and R6-R7.
增加交叉备份链路在：R1-R4, R2-R3, R5-R8, R6-R7
D. Make R3 and R8 have lower HSRP priority than R1 and R7.
E. Replace HSRP with VRRP. Answer: BC
33. Network A has a spanning-tree problem in which the traffic is selecting a longer path. How is the path cost calculated?
网络A 的生成树，其中一条很长的路径，他的成本怎么计算？
A. number of hops B. priority of the bridge C. interface bandwidth D. interface delay E. None of the above Answer: C
34. You deployed new fibers in your networkto replace copper spans that were too long. While reconnecting the network, you experienced network problems because you reconnected wrong fibers to wrong ports. What could you do to prevent this type of problem in the future, particularly when connecting and reconnecting fiber pairs?
你正在部署你的网络拥光纤来替代过长的铜线路， 在从新联网时你遇到了问题。 因为你错误 的链接了发送接收端口， 你可以做什么来防止以后在发生这样的事情， 特别是在链接一对光 纤的时候
A. Only use fiber in pairs. B. Configure root guard on your switches. C. Do not use fiber but use copper. D. Configure UDLD to prevent one-way link conditions.
配置UDLD来防止单向链路的问题。
Answer: D
35. Refer to the exhibit. Look at the command output. What can you use to prevent this behavior?
如图所示，看到这个命令的输出。怎么能阻止这种行为？
A. UDLD (UniDirectional Link Detection 单向链路检测) B. spanning-tree loopguard C. VTP mode transparent D. switchport mode desirable
Answer: A
