10.26日过640-607,987分,发表85%完整战报
题目数量:60 时长:2小时(很充分) 多项选择题目一般都有说明叫你选几个,如(select best two) 还是那个老话,TK20+战斗报告=99.9的题目: 先说实验,这个记得清楚: 1.就是TK20上的NO.342,三个路由器不通,让你搞通, 先show ip interface brief查了每个的ip都配置好也up了,再show run查,发现第一个路由器的rip网没有 配置完成,因此 router rip,network 192.168.19.0,network 192.168.21.0,copy run start, 搞定,可以用show ip router,ping 来验证路由表已完全了,互相可ping通了,就next--> 2.另一道是也是战报常见题,给一个路由器的e0和s1接口配置ip地址的,该地址是某个 网络192.168.81.0/27前1、2个网络号的第一个ip地址,(忽略子网络号0) 计算:e0 192.168.81.33 255.255.255.224 s0 192.168.81.65 255.255.255.224 配置:int e0,no shutdown,ip address 192.168.81.33 255.255.255.224, int s0,no shutdown,ip address 192.168.81.65 255.255.255.224, copy run start 验证:可ping 通旁边的路由器的各个端口. ================================================================== 下面的题目我从前几天的战报中并结合本人的记忆copy过来,因为我考的确实是战报上的,幸运吧? @_@ 1. 一个admin tenet 到router 运行debug frame-relay lmi 后等了40s 也没任何debug message问要怎么办? 选terminal monitor 2.Switches have three primary modes to handle frame switching.
