902为什么大家都普遍说没难度?832如何快速解题?813中的不能打dot1q命令真的是BUG嘛?下面分享一点我的个人心得
4 L% j5 V2 y& c" B' V y27日考完的一直没有时间发战报,下面说说我考813,832,902 这些屈折的考证路程吧.希望对大家有所帮助8 @2 Y) @7 v/ y
5 X6 ]6 U, @% T) x6 ~( o( X. }5 W1.902, 路由这门应该说是大家普遍认为三门中简单的因为曾经有过NA首战挂科的阴影,NP的第一门也选择比较简单的902.复习看题库近2个礼拜后考试,总体来说题库覆盖全面,选择题无压力,实验题照旧.参考鸿鹄题库就行了,注意看题,尤其鸿鹄提到的重分布那个题干关键字我遇到了.6 ~& Z& M3 f+ z- @ ^
2.832,排错,当初不知道听哪个大牛说的只复习2天就去考了,我居然也就看了2天题库视频就去了,其实832也没啥难点,这个学过NP,以后准备从事网络技术行业的都应该会,题库的价值体现不是很大了,不过解题思路值得大家参考.还有就是似乎有BUG一说,至少我看到13/12 (12/13?)这种诡异的提示,然后所有题目都已经done红了... 最后无奈点了next的..." b, v! I$ p6 V% r7 V

813,交换,传说中三门最难,我也觉得最难的,本来学的时候没学好,交换机的模拟器也有限,难度嘛,说真的我只是觉得选择题难度大(懒的背),三个必考实验,aaa eigrp hsrp ,中公认的hsrp最难,我在考试时候被题目看晕了,找关键字居然有提到vtp stp,难不成要如题库所说可能让我配置vtp? 反正我当时考试的时候配置了,测试没效果,当时就在排错,f0/3 - 4 已经trunk了接口也开了,域名也对了就是没学到,没办法 只能双方都手动打了vlan 信息,估计这个不需要配,我多此一举了,再者大家关注的一个交换机不能打sw trunk encap dot1q 这个问题我找到症结了,考试的时候我分别show version了两台机器发现一台是 3560 ,一台是2950(60?),2950(SWB)不需要打 sw trunk encap dot1q ,而且你也打不了,这个是正常的,不需要纠结,另外一边3560 (SWA,三层交换机)必须要打。至于为什么,大家可以在模拟器或者真机中实验一下就知道了。
