思科CCIE認證主要考試內容是什麼?今天yjbys小編為大家分享的是CCIE認證考試模擬試題及答案，僅供同學們複習!
1. Two BGP peers connected through a routed firewall are unable to establish a peering relationship. What could be the most likely cause?
兩個直連BGP鄰居，無法通過防火牆建立鄰居關係，最有可能是什麼原因?
A. BGP peers must be Layer 2-adjacent. B. EBGP multihop is not configured. EBGP鄰居的多跳沒有設定 C. The firewall is not configured to allow IP protocol 89. D. The firewall is not configured to allow UDP 179.
Answer: B
2. Which two of these steps are minimum requirements to configure OSPFv3 under IPv6? (Choose two.) 需要哪兩個步驟開始用最基本在IPv6上使用OSPFv3協議 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
3. 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”使用者現在抱怨在Voip服務中語音通訊質量很差，你該怎麼做?
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. 刪除這條配置命令 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
4. Refer to the exhibit. How would you get the network into the OSPF database?
如圖所示，怎麼做可以讓網路進入OSPF資料庫中?
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.
建立一條虛鏈路在區域1和區域0之間
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 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
5. Refer to the exhibit. Router E learned about the PIM RP (designated as ) from four different sources. Routers A and D advertised the network via EIGRP. Routers B and C advertised the 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?
如圖所示，路由器E從不同渠道學習的的路由。路由器A和D在EIGRP中通告的` 的路由，路由器B和C在OSPF中通告的的路由。考慮到4個網口都能連線到PIM-RP。 當路由器E收到第一個多播包在共享樹。哪個介面能在入方向通過RPF檢查?(答案可能有不準)
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
