CCNA复习资料——RIP(上)

时间:2018-02-02 14:23:42

 1、Refer to exhibit. The company uses EIGRP as the routing protocol. What path will packets take from a host on 192.168.10.192/26 network to a host on the LAN attached to router R1?
 一个公司使用Eigrp路由协议, 一个数据包从192.168.10.192/26网络中到达R1的以太网络中将如何选路?
CCNA复习资料——RIP(上)
 

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
图中Eigrp链路开销链路带宽都是一样的所以路径就是R3--R1

2Refer 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.)
假定参考的路由协议在下面的每个选项都已经使用默认设置配置完 毕,并且给定的路由协议在所有路由器上正在运行。哪两个有条件的 状态信息准确的描述了这条路径,这条路径在网络10.1.0.010.3.2.0之间被选择,并且被路由协议提到过?
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
距离矢量(( RIP)路由选路看跳数, 链路状态路由要看链路的一个综合参数,针对本题来说,主要 就是带宽,带宽越快越会被优先选择,因此答案为AE
 
3 What are two characteristics of RIPv2? (Choose two.) RIPv2的两个特征是什么?(选择两个。)
A. classful routing protocol 有类路由协议 错 是无类路由协议
B. variable-length subnet masks 可变的子网掩码 正确
C. broadcast addressing 广播地址 应该是组播地址 V1是广播
D. manual route summarization  手动汇总 正确
E. uses SPF algorithm to compute path 使用SPF算法来计算路径 错 这个是连接状态协议的算法
Answer: BD
 
4 Refer to the exhibit. Which rule does the DHCP server use when there is an IP address conflict? 参考图示。哪个规则DHCP服务器时使用IP地址冲突?
CCNA复习资料——RIP(上)
 

A. The address is removed from the pool until the conflict is resolved.
被冲突的地址从地址池中移除直到冲突结束
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冲突解决
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
