首先，感谢“可爱De月”给了小弟这个账号，从而有兴来到大名顶顶的菊花论坛。我会坚持上线就去投小宝宝的票，以示感谢。
上来本坛后，感觉讨论问题的很少，大量帖子都是下载(题库，笔记.......)，但这些资料坛上FTP都有，很全并且也有高手定期更新，感觉很多，也向各位达人致敬，您们辛苦了。FTP要钱，为了换到几个钱花，只能到水库放水，感谢几位好心人和版猪们给我加分添钱。
马屁拍完了，现在说一下开此贴的目的：挣个小钱；开自留地为自己CCNA之路留下痕迹；没事就写点东西，便于总结；有一条线可以牵着自己，长“加家”看看，知道自己离PASS还有多远。错了一道不应错的题，想返回去重改，但发现不象p4s，不能退回，当时郁闷的要死，请以后考的同仁注意。

p4s覆盖很高，如果弄懂3.20,通过是没有问题的。先说遇到几个新题是3.20里没及 的：

.Refer to the exhibit. In order to determine the cause of the excessive collisions, what step
would be appropriate concerning fastEthernet 0/2?

A Check the continuity of the cable.
B Inspect the cable environment for excessive electromagnetic noise.
C Ensure Category 5 cabling is being used.
D Verify that the cable length does not exceed the specified length.
ANSWER: D
还有一道不好意思想不起来了。

353那道VTP的题我抽到了，题目和题库上是完全一样的。答案应该是只有Configration reversion高的。
实验题是EIGRP和RIPV2的，基本上和题库的一样，就是IP ADDRESS 和AS不一样，22和12，把22改为12。
大题是VLAN(352-356)完全一样，DHCP的(348-351)和TK完全相同，那个还有设置端口和设备类型的那个（258)变化很大，类型和IP都变了，更奇怪的是其中有两个IP是完全相同的，当时不敢相信自己的眼睛，PASS4SURE的题会有问题，CISCO不会也有问题吧，但也没有办法，就按显示的做了。
195题的方向改了，原题为A->B，而我遇到的是B->A所以提醒您还是要注意看下题。
其他的也就没有什么了。

书已经看完了，基本理解，但不知道如何提高动手能力，怎么保证实验效果呢？

同感，哎。。。。。。。。。。。。。

QUESTION NO: 1
Network Topology Exhibit: Configuration exhibit: Leading the way in IT testing and certification tools, www.testking.com - 658 - You work as a network technician at TestKing.com. Study the exhibits carefully. The Frame-Relay network in the diagram is not functioning properly. Based on the information shown above, what is the cause of the problem?


2008-8-19 18:23
A. The S3 interface of the TestKing2 router has been configured with the "frame relay encapsulation ietf" command
B. The Frame-relay map statement in the TestKing3 router for the PVC to TestKing2 is not correct
C. The TestKing1 router has the wrong LMI type configured
D. Inverse ARP is providing the wrong PVC information to the TestKing1 Router
E. The IP Address on the serial interface of the TestKing3 router is configured incorrectly F. None of the above

给的答案是B，但个人感觉E也是一个原因，请您讨论

同感，哎！！！！！！！！！！！！！！！！！！！！！！！！

动手能力也应没有问题了，但还是没有100的把握，看来还是等下新的题库吧，不知道什么时候能出来。

E的意思是:TK3路由器串口IP地址配置不正确
干扰项 看清楚题目

QUESTION NO: 25
Study the output script and the network topology exhibit below:
TestKing1# show running-config
<some output text omitted>
interface serial0/0
bandwidth 64
ip address 172.16.100.2 255.255.0.0
encapsulation frame-relay
frame-relay map ip 172.16.100.1 100 broadcast



The Router TestKing1 in Hong Kong is connected to the router TestKing2 in Tokyo
via a new Frame Relay link. However, TestKing1 is unable to communicate with
TestKing2. Based on the above output, what do you suspect as the underlying cause
of this problem?
A. Bandwidth configuration incorrect
B. IP address not correct
C. Improper map statement
D. Improper LMI configuration
E. None of the above
Answer: C
Explanation: From looking at the diagram you can see that Hong Kong's DLCI is
100, while Tokyo's DLCI is 200,不明白是什么问题。
frame-relay map ip 172.16.100.1 100 broadcast有错吗？
The Frame Relay map command is an interface configuration mode command that
statically defines a mapping between a network layer address and a DLCI.

但从拓朴图上知testKing3的IP是172.31.31.62,但从TestKing1和2的sh frame-relay mpa 上看TestKing3的IP不是172.31.31.126吗？

排版错误吧.

QUESTION NO: 26
While troubleshooting an issue with your frame relay network, you issue the "show
frame pvc" command as shown in the exhibit below:
You're a network administrator at a TestKing branch office, that's connected to the
central headquarters by means of Frame Relay. You've been getting complaints that
the connection has suddenly become slow, so you make the assumption that there's
too much traffic going through the link.
Taking into consideration the above output from the 'show frame relay pvc'
command; which command output value is indicating that there's congestion
between the local router and the corporate site?


A. in DE packets 0
B. last time PVC status changed 00:25:40
C. in BECN packets 192
D. DLCI = 100
E. in FECN packets 147
Answer: C
Explanation:
BECN stands for Backward Explicit Congestion Notification. The BECN tells the
transmitting device that the Frame Relay network is congested and that it should "back
off" to allow better throughput. BECN and FECN go hand to hand together, but since the
question specifically asks for what's indicating congestion between the local router and
corporate site, BECN is correct.
还是有些不明白，请高人指点。

貌似25的frame-relay map 没错啊

26可以看ccna学习指南 有讲到这个东西

4楼和8楼都是排版错误,这样题目在TK中不少.

哎，E文啊！

中文的这里有:http://www.sharecenter.net/thread-148412-1-1.html

其实题目的英文词汇量很有限 看多了就好了

还是要努力。。。。。。。。背题

背题，用的很不适当，个人意见。
看题库是有必要的，要理解人家为什么出这道题，想考查的知识点是什么，对于这个知识点你掌握了没有。
当然如果你的目标就只是CCNA，你可以背，如果您还想往前走，个人认为夯实基础很重要。

不一定要背 但一定要看 题库的题目真的很经典 思科那帮工程师出题很有水平

背题是客观存在的事情,存在的就是合理的.
说实话,如果经济条件好,谁都想用最容易的方式通过认证.
个人不推荐背题目,实践中碰到问题会很棘手的.
