一個(gè)公司使用Eigrp路由協(xié)議， 一個(gè)數(shù)據(jù)包從192.168.10.192/26網(wǎng)絡(luò)中到達(dá)R1的以太網(wǎng)絡(luò)中將如何選路？
A.The path of the packets will be R3 to R2 to R1.
B.The path of the packets will be R3 to R1 to R2.
C.The path of the packets will be both R3 to R2 to R1 AND R3 to R1.
D.The path of the packets will be R3 to R1.
Answer:D
圖中Eigrp鏈路開(kāi)銷(xiāo)鏈路帶寬都是一樣的所以路徑就是R3--R1
2、Refer to the exhibit. Assume that the routing protocol referenced in each choice below is configured with its default settings and the given routing protocol is running on all the routers. Which two conditional statements accurately state the path that will be chosen between networks 10.1.0.0 and 10.3.2.0 for the routing protocol mentioned? (Choose two.)
假定參考的路由協(xié)議在下面的每個(gè)選項(xiàng)都已經(jīng)使用默認(rèn)設(shè)置配置完 畢，并且給定的路由協(xié)議在所有路由器上正在運(yùn)行。哪兩個(gè)有條件的 狀態(tài)信息準(zhǔn)確的描述了這條路徑，這條路徑在網(wǎng)絡(luò)10.1.0.0和10.3.2.0之間被選擇，并且被路由協(xié)議提到過(guò)？
A. If OSPF is the routing protocol, the path will be from R1 to R3 to R4 to R5.
B. If OSPF is the routing protocol, the path will be from R1 to R2 to R5.
C. If OSPF is the routing protocol, the path will be from R1 to R5.
D. If RIPv2 is the routing protocol, the path will be from R1 to R3 to R4 to R5.
E. If RIPv2 is the routing protocol, the path will be from R1 to R5.
Answer: AE
距離矢量（( RIP)路由選路看跳數(shù)， 鏈路狀態(tài)路由要看鏈路的一個(gè)綜合參數(shù),針對(duì)本題來(lái)說(shuō)，主要 就是帶寬，帶寬越快越會(huì)被優(yōu)先選擇，因此答案為AE
3、 What are two characteristics of RIPv2? (Choose two.) RIPv2的兩個(gè)特征是什么?(選擇兩個(gè)。)
A. classful routing protocol 有類(lèi)路由協(xié)議 錯(cuò) 是無(wú)類(lèi)路由協(xié)議
B. variable-length subnet masks 可變的子網(wǎng)掩碼 正確
C. broadcast addressing 廣播地址 應(yīng)該是組播地址 V1是廣播
D. manual route summarization 手動(dòng)匯總 正確
E. uses SPF algorithm to compute path 使用SPF算法來(lái)計(jì)算路徑 錯(cuò) 這個(gè)是連接狀態(tài)協(xié)議的算法
Answer: BD
4、 Refer to the exhibit. Which rule does the DHCP server use when there is an IP address conflict? 參考圖示。哪個(gè)規(guī)則DHCP服務(wù)器時(shí)使用IP地址沖突?
A. The address is removed from the pool until the conflict is resolved.
被沖突的地址從地址池中移除直到?jīng)_突結(jié)束
B. The address remains in the pool until the conflict is resolved.
地址被保留子在地址池中直到?jīng)_突解決
C. Only the IP detected by Gratuitous ARP is removed from the pool.
D. Only the IP detected by Ping is removed from the pool.
E. The IP will be shown, even after the conflict is resolved.
Answer: A
