The IP address 10.10.10.6 is configured on S0/1. C. The IP address 10.10.10.8 is configured on S0/1. D. This route is using the default administrative distance. E. The 10.10.10.8 network is two hops away from this router. Explanation/Reference: |
問題86
在圖中show ip route那行指令輸出顯示, 可以確認什麼?(選擇兩項)。 A.可以預期在35秒內的下一個路由更新。 B.上配置IP地址10.10.10.6 S0 / 1。 C. S0 / 1的IP地址10.10.10.8配置。 D. 這條航線使用的默認管理距離。 E. 10.10.10.8網絡的兩跳距離該路由器。 |
答:DE
考點:考查RIP的路由條目。通過RIP學習到一條到達10.10.10.8的路由,下一跳是10.10.10.6,出接口是s/1。 A:錯誤。rip更新周期為30s,正常計時器不會超過30 B:錯誤,這個ip是對端接口ip C:錯誤。s0/1的ip無法得知 D:正確,rip缺省的管理距離是120 E:正確。 |
QUESTION 90
Refer to the exhibit. Assume that all of the router interfaces are operational and configured correctly. How will router R2 be affected by the configuration of R1 that is shown in the exhibit? A. Router R2 will not form a neighbor relationship with R1. B. Router R2 will obtain a full routing table, including a default route, from R1. C. R2 will obtain OSPF updates from R1, but will not obtain a default route from R1. D. R2 will not have a route for the directly connected serial network, but all other directly connected networks will be present, as well as the two Ethernet networks connected to R1.. |
問題90
請參閱圖示。假設所有的路由器接口皆能操作並正確配置。路由器R2在圖中是如何受到R1配置的影響? A.路由器R2 R1。 B. 不會形成鄰居關係 路由器R2將獲得完整的路由表,其中包括一個默認路由,從R1。 C. 從R1,R2將獲得OSPF更新,但不會獲得一個默認路由R1。 D. R2不會有直接相連的串行網絡的路由,但其他所有直接連接的網絡,以及兩個以太網網絡連接到R1的。 |
答:B
考查OSPF產生默認路由的條件雖然默認路由出口錯誤但是鄰居仍然回收到 正確答案選:B |
QUESTION 92
Refer to the exhibit. A packet with a source IP address of 192.168.2.4 and a destination IP address of 10.1.1.4 arrives at the HokesB router. What action does the router take? A. forwards the received packet out the Serial0/0 interface B. forwards a packet containing an EIGRP advertisement out the Serial0/1 interface C. forwards a packet containing an ICMP message out the FastEthernet0/0 interface D. forwards a packet containing an ARP request out the FastEthernet0/1 interface. |
問題92
請參閱圖示。IP地址為192.168.2.4的封包, 以及目標IP地址為10.1.1.4抵達HokesB路由器 。該路由器應該做什麼動作? A.把接收到的數據包了Serial0 / 0接口 B. 轉發一個數據包中包含的Serial0 / 1接口 C.轉發了FastEthernet0 / 0接口 D.轉發的數據包包含了從FastEthernet0 / 1接口的ARP請求數據包包含一個ICMP消息的的EIGRP廣告了 |
答:C
路由器中沒有去往目的地的路由,返回一個ICMP報錯報文去往源IP的路由下一跳是f0/0,所以選C |
QUESTION 93
Refer to the exhibit. From RouterA, a network administrator is able to ping the serial interface of RouterB but unable to ping any of the subnets attached to RouterB. Based on the partial outputs in the exhibit, what could be the problem? A. EIGRP does not support VLSM. B. The EIGRP network statements are incorrectly configured. C. The IP addressing on the serial interface of RouterA is incorrect. D. The routing protocol has summarized on the classful boundary. E. EIGRP has been configured with an invalid autonomous system number. |
問題93
請參閱圖示。在路由器A上,網路管理員能夠ping RouterB上的串行接口,但無法ping通任何連接到路由器B的的子網路。在下圖中的部分輸出,可能是什麼問題? A. EIGRP不支持VLSM。 B. EIGRP網絡報表配置不正確。 C. 上RouterA上的串行接口的IP地址是不正確的。 D.路由協議 總結類邊界。 E.EIGRP已經配置了一個無效的自治系統號。 |
答:D
在RouterB上“show ip route命令”命令的輸出中,RouterB學習不到在RouterA上的任何網絡。 此外“172.16.0.0/26 is a summary,00:00:03,NULL0”這行告訴我們這是一個路由匯整總結。 |
