51. Two BGP peers connected through a routed firewall are unable to establish a peering relationship. What could be the most likely cause?
两个直连BGP邻居，无法通过防火墙建立邻居关系，最有可能是什么原因？
A. BGP peers must be Layer 2-adjacent.
B. EBGP multihop is not configured. EBGP邻居的多跳没有设置
C. The firewall is not configured to allow IP protocol 89.
D. The firewall is not configured to allow UDP 179.
Answer: B
52. Which two of these steps are minimum requirements to configure OSPFv3 under IPv6? (Choose two.) 需要哪两个步骤开始用最基本在IPv6上使用OSPFv3协议 A. Configure a routing process using the command ipv6 router ospf [process-id]. B. Add the network statement for the interfaces on which OSPF will run. C. Configure OSPF on the interface that it will run on. D. Use the passive-interface command on the interfaces on which OSPF should not run. E. Enable routing.
Answer: CE
53. You add the following commands into a routed topology: router eigrp 1 variance 3 traffic-share min across-interfaces. Users now complain about voice quality in your VoIP system. What should be done?
你在路由器上加入了下面的命令 “router eigrp 1 variance 3 traffic-share min across-interfaces”用户现在抱怨在Voip服务中语音通信质量很差，你该怎么做？
A. Add the command: router eigrp 1 traffic-share voice interface fast 0/0.
B. Reconfigure EIGRP to recognize voice packets. C. Remove the variance from the configuration. 删除这条配置命令
D. Reconfigure the VoIP system to use RTP sequence number headers.
E. Use an H.323 gatekeeper for your VoIP system to negotiate an H.245 uneven packet buffer.
F. Reconfigure EIGRP to version 2.
Answer: C
5. Refer to the exhibit. How would you get the 1.1.1.1 network into the OSPF database?
怎么做可以让1.1.1.1网络进入OSPF数据库中？
A. Configure RTA as an ASBR.
B. Redistribute connected routes on RTA into OSPF.
C. Set up a virtual link between area 1 and area 0.
建立一条虚链路在区域1和区域0之间
D. Set up a virtual link between area 1 and area 2.
E. Add a static route into RTB and enter it into OSPF.
F. Place a network 1.1.1.0 0.0.0.0 command into RTB. G. Set up a unique router ID on RTA using an RFC 1918 address. H. Change area 0 on RTB to area 1
Answer: C
55. Refer to the exhibit. Router E learned about the PIM RP (designated as 7.7.7.7) from four different sources. Routers A and D advertised the 7.0.0.0 network via EIGRP. Routers B and C advertised the 7.0.0.0 network via OSPF. Considering that all four Ethernet interfaces on router E could potentially lead back to the PIM-RP, when router E receives the first multicast packet down the shared tree, which incoming interface will be used to successfully pass the RPF check?
A. E0
B. E1
C. E2
D. E3
E. None of these interfaces will be used to successfully pass the RPF check.
F. All of these interfaces would successfully pass the RPF check.
Answer: A
