/ |; T2 u K. |重点说下813,做天刚过的。运气不好,上来两题就是Lacp+MLS,第8、9题的样子又遇到AAA,前10题就把实验题搞定了。后面遇到3道托图和几道有争议的题,没有新题。 x+ P/ f" M" _9 c1 ~/ s0 `

我看了两个题库,一个是鸿鹄论坛2013.11.7的题库,一个是论坛里面之前有人发的197的题库。& x+ x' C, H7 u; T6 {& {

5 p7 o+ M+ T6 S# s先说Lacp,Lacp我按照197的题库,先把fa0/3-4划进channel-group 1,再在port-channel 1 里面做的配置,但是做完后show interface trunk死活看不到信息,不知道是不是bug,没办法,又在interface rangge fa0/3-4接口下面把配置也做了一遍,才ok。所以考试的时候建议大家在两个下面都做。然后需要注意的是interface rangge fa0/3-4这类命令,- 符号的两边都要留一个空格,不然会报错。1 Z4 O8 d1 M! Q# d* c

再说HSRP,考试的时候证明是和197题库的吻合,而且考试的时候连答案顺序都没变,完全就是送分。不过保险起见,建议大家两种题库都看一下。重点是要理解。

! l/ J8 d8 d+ e最后有一道托图题,鸿鹄两个题库的答案不一样。我按照197的选的,是正确的。第一次发帖,不知道怎么截图。就是197题库拖图题的第1题,对应是鸿鹄论坛2013.11.7题库的话就是托图第17题。第二个图框要选what routing protocol will be used。大家下载一下附件就好了。

% D T$ ]9 F% z' R( j说了这么多,其实就一个原则,两个题库都要记好,遇到答案不同的题,以197的为准,LACP建议在channel和接口下都做配置。希望大家考试顺利。
