4-7 东莞896低分通过

jyleecn · 发表于 2017-4-7 18:00:27

一上来就是一道新题，是关于IPv4的，不过还好，有点基础的都能做对。期间一共4道新题，复习4.7题库稳过。其实做题的时候我觉得自己是970的。。。因为真的跟题库一模一样，可能我实验题没做好吧。说回实验题，抽到的是ACL3和OSPF。ACL题目和题库有点出入，主要是最后一条acl条目不同了。抽到的题目已经给出Public server的IP地址。最后一条条目不是access-list 100 permit ip any any而是access-list 100 permit ip any host 172.22.242.18.
OSPF的话和PDF第三页那道是一样的。
没出拖图题有点可惜，因为我自己很喜欢做拖图题，很稳。如果是刚开始准备的朋友，建议直接用电脑软件来刷题，要比看PDF高效很多，等电脑软件刷得差不多的时候，再把答案顺序打乱的那个选项打开！！！这个一定要打乱答案的顺序，我4月7号下午考，早上才知道有这么一个功能可以打算ABCD的顺序。。。。因为一些题你会自然而然地记住每个选项的位置的，这样很不利于考试，因为考试是打乱的。
打乱顺序的方法是打开软件，到option那里，找到randomize choices where enabled并且勾选上。
randomize questions 是打乱题目顺序
randomize choices where enabled 是打乱选项顺序的

以下是我记得的题目：
QUESTION 24
Refer to the exhibit. The following commands are executed on interface fa0/1 of 2950Switch.

The Ethernet frame that is shown arrives on interface fa0/1. What two functions will occur when this frame
is received by 2950Switch? (Choose two.)
