9.1的1000分完整战报、经验以及解说（转帖)

9.1的1000分完整战报、经验以及解说（强烈推荐看！！） 我是9.1去考试中心考试的一次性满分通过。下面的文章分“考试全过程”和“试题回忆”两部分，新手从头看起。老手看需要部分。可以发表意见，但是不要扁我，我最讨厌人家扁我了。：） ========考试全过程============================================================= 1，先去考试中心去注册，带着前和有关证件； 2，然后定好考试日期； 3，回来安心复习。这个时候你应该已经具有了相当的水平才好。觉得自己不能考“一定”要提前3到7天（这个时间你应该问问，免得有变化）去考试中心推迟考期。也就是说你应该提前考试前好几天已经行了才好。 我的考试过程：注册，备考，考试，通过。 复习我这人喜欢先搞基础，做题之前一定要把书看个几遍弄到懂了才肯做题。（其实，后来证明我应该看书做题两结合。）所以直到考试前两天我才开始看Testking20,那么多题看了我将近两天，真是晕啊。考试前一天还在看，晚上一下看到凌晨3点多才睡觉，睡了又睡不着。第二天7点我就起床了。然后就去了考试中心。（我精力很好的，睡一会就够了，考试回来一样还是没有睡午觉。一般说来大多数人还是应该好好休息好，免得发挥不好）没有带书，只带了自己的一点点笔记，路上翻了翻。到那里顺便还看了看最近的战报。很快就上场了。 考试因为是第一次考试很紧张，而且还进不去，只好叫来了考场管理员给弄好。考试开始是个个人水平等的调查，我是基本都是选的bening level。不知道会不会和考试题难易程度有一定关系。提醒一点的是有个你不能外传考试题目之类的那一项你一定要I agree.否则你的成绩也许会没有作废。我看着看着就烦了干脆只要是选同意不同意都同意，我还怕它。正式的考试我很小心，任何一个题不敢轻心，一定要看两遍才动手，这事《甘十九妹》中早就说过了：搏虎全力搏兔也全力。在30道左右的时候出现第一个实验，字小得象砸扁的蚂蚁。不知道是不是我运气不是很好，我遇到的几乎全是多选题，方法很简单正着选一遍再排除法选一遍。这过程一直到结束。等它出成绩，谁知道后面居然还有一个调查，我还以为考试白考了呢。赶紧叫来了管理员。管理员出去，这个时候我听到他们在说不会吧满分这么牛。心中暗喜，不喜也不可能啊是不是？——那时侯考场就我自己，我旁边那个考NP的早就走了。出来确定真是我，那简直开心死了。 考试技巧选项中有一些是不相干的，不是。有无效或者说错误的命令是来干扰你的，不是。它们可以帮助选定最后答案和验证绝对会的一定不要狂喜，也许你看错了一个单词，其实你选反了，更不要会做但是误选错了。最大的技巧就是你没有技巧，你真的会，那绝对是没有问题的。其实英语也用不到多好，我看有个高中水平就够了，看看原版书，专业词语毕竟不多，看长了就是想忘也忘不了。 TK20的覆盖率真的很高，应该认真看，不要象我，TK20只匆匆看了一遍，好多题目看着眼熟，但是选项还是要自己推敲推敲。 注意：看题目时候不要背顺序，至少你也得知道被选的大概是什么意思，顺序有的不换但是有的绝对会换的。注意一些细节性的问题，比如是access-list 不是access list，是cppy run start 不是copy ran start,这样你会少错一点。以下都是我对照TK20以及一些别的资料回忆的。 我觉得我能过NA应该感谢三个人：一个是；李挺老师，是他把我带到了“网络”这座大门的门口；一个是郭宁老师，他是我的“教练”，他把我带进了“网络”这个门。他的课讲的非常好，他在实验和理论方面给予我耐心而细致的指导，我的通过绝对和他的悉心指教密切相关的。一个人是我自己，因为我在学习过程中教会了自己“凡事都要努力，懒惰者必败”。 建议也许你应该给自己找个同道做伴侣，这样你不孤独也进步很快。有很多网友帮助过我，我心中都一一记得。也谢谢你们。 考试范围虽然瑞通的培训教材已经跟着形势做了最新的升级，但是，我觉得近来的考试似乎还是过去的内容，IPX不考，而新近加进来的Switch2950的配置、Eigrp、ospf、NAT以及各章新加的一些内容暂时都没有出现在考试中，可以在复习中不复习他们，除非你的时间充足。当然你越是靠近后面考试，最好要看一下，并且跟踪最新的报道。也说不定CISCO会忽然变题，毕竟不是我出题，那时你找我也没有用。 考试资料书 + TK20 + 最新的战报，就足够了。好多人喜欢做BOSON，我倒是觉得无所谓，我就做了一套，后开我询问了我的“教练”，他说BOSON上的覆盖率并不是很高，所以我就没有再做，现在看来也是正确的抉择。其余的一些资料我也收集很多，但是都没有看。 =========考试真题============================================================= 1,QUESTION NO: 2(好象考到) Frame Tagging is used to interconnect multiple switches and to maintain VLAN information as traffic goes between switches. Which of the following statements about the Frame Tagging are true? (Choose two) A. A Filtering table is developed for each switch. B. Frame Tagging defines a unique user defined ID to each frame. C.

(Choose two.) A. Non-reliable B. Reliable C. Less bandwidth-intensive D. Handshaking Answer: B, D TCP is a connection-oriented protocol.

What is a disadvantage of using a connection-oriented protocol such as TCP? A. Packet acknowledgement may add overhead. B. Packets are not tagged with sequence numbers. C. Loss or duplication of data packets is more likely to occur. D. The application layer must assume responsibility for correct sequencing of the data packets. Answer: A. 4,交换机中无错(error free)的传输方式是那一种：store and forward. 5, QUESTION NO: 7 Which of the following are Application layer protocols that use TCP/IP? (Choose three.) A. ARP B. HTTP C. SMTP D. FTP E.

To increase the number of collision domains. D. To decrease the number of collision domains. E. To decrease the number of broadcast domains. Answer: A, C. 注意：关于collisions、collision domains、broadcast、broadcast domains、broadcast size、 collision size是一定要区分的几个概念。这个是必考的题。你要记得交换机增加collision domains减少collision size不改变broadcast domains的number；路由器增加the number of broadcast domains减少broadcast size但是不改变the number of collision domains。（比如QUESTION NO: 40、QUESTION NO: 98） 10，QUESTION NO: 20 Full-duplex gives you the ability to send and receive data at the same time.

Answer: C. 29，大概就是在这里，我遇到了第一个实验题，（前面的顺序不是原来的顺序啊，我可没有那么大本事给记那么清楚，人脑不比电脑啊，呵呵i还是那个router rip 的排错。题目的大体意思是：有三个路由器分别叫A、Builiding、G（就是这个意思，不是原名字了）,已经配置好，但是不能连通，RIP是路由协议，S0口配时钟。 步骤：a、先把三个路由器的各个接口的地址写下来（建议你这样做）； b、show run 目的是看接口有没有地址，有没有no shut，看路由协议有没有陪全。 C、发现没有配全RIP所以用NETWORK X.X.X.X命令配上。 D、copy running-config startup-config E、ping 各个接口。通了。 F、NEXT就行了。 注意点：第一，你不知道哪个上少了配置，所以你顺便登录一个就行，要是你没有发先问题，那么假定它没有问题。然后用telnet登录到相临的路由器，进行配置（一定是和你相直连的那个接口啊，别犯傻顺便乱登，你的这个路由器现在还学不到不相临的地址呢）。 第二，配好了先保存，免得一会你PING通了一高兴忘记了，那还不亏了。 第三，rip igrp 是有类路由，所以使用network命令时候不要带掩码，与子网无关主机位置要为0，比如：network 10.0.0.0而不是写成network 10.1.2.0什么的。顺便说一下，EIGRP是无类路由，但是它的NETWORK命令中也一样是和有类的一样——不带掩码不带子网。在CCNA考试中路由协议配置中只有OSPF要带掩码而且是反向掩码。 第四，实验题的字很小很小，就象一只蚂蚁砸一下让后让你认是什么。很不幸，大家都避免不了，没有办法靠近点就当是考古吧：（。 第二实验是算子网掩码的，还是那个题目。 30，QUESTION NO: 88 Using a protocol analyzer you determine your LAN traffic is experiencing congestion.

What would be the correct subnet mask to accomplish this division keeping the number of subnets at the maximum? Type the correct value in each box below. Answer:255.255.254.0 注：这个是我的第一个题目，我输入255.255.254.0时候，变成了266.266.264.0了，怎么输入都是，当时还不把我急死了，这可是第一个题啊！！！！后来也只好那样过去了，也不知道是不是上面字太小的缘故。 40，QUESTION NO: 164（好象有） What does ISL trunking protocol use to identify the VLAN membership of a frame over trunked links? A. Frame filtering with VLAN ID B. Frame tagging with VLAN ID C. Frame filtering with trunk ID D. Frame tagging with trunk ID E.

A. cut-through B. fragment-free C. frame-filtering D. store-and-forward E. 802.1q forwarding F. VTP transparent mode Answer: D 58，QUESTION NO: 360 Which command is used to display the placement and direction of an IP access control list on a router? A. show access-list B. show ip route C. show ip interface D. show interface E. show interface list F. show ip interface brief Answer: C 59，配置好rip路由协议后，看rip的更新情况的命令：debugiprip。 60，如果远程路由器不支持反向ARP，或者使用路由选择时想要控制流量怎么进行DLCI表的映射?（选择题） Answer：router(config-if)#frame-relay map 61，显示frame-relay 的映射的两条命令：（选择题） show frame-relay map shoe frame-relay pvc 62，IOS的加载问题。路由器启动后无论输入什么命令都说没有该命令。原因？ A: B:IOS image is delete or —— C: D:RAM is corrupted 注：这个题可能有的朋友考试时候有选项是ios image is corrupted,所以我做这个题目时候差点误选了D选项，但是，B的表达才是对的。请一定注意！！！！！！！！！！！！！！！！！！！！！！！ 63,VLAN2中的机器想与VLAN3中的机器通信，怎么办？ A：routed B：(忘记了) C:（忘记了） D:share enable Answer:A. 注：关于这个题目，有的考生中没有routed这个选项，那就选D吧。有routed这个选项一定就是它了，没有任何怀疑。我看到有好几个的考生中routed这个选项是在B中出现的，但是我的确实是在第一个选项中出现的，我当时很留心！！它在哪里出现不重要，只要出N，它肯定是首选！ 63：这个题还是子网掩码的问题。我特意在最后提出来，一是因为它重要一是想请有关朋友进行把原题补充出来。 图是： router1-------------------router2 10.1.2.34/22 | | 10.1.2.255/22 | | switch1 switch2 | | | | ------------- -------------- | | | | pc1 pc2 pc3 pc4 问题好象是问所有的pc都配置正确为什么switch1下的pc不能和switch2下的pc通信。 注：这个题的图我画的是正确的，但是叙述，我已经很努力了，实在是想不起来了。请各位把子网划分和（算或者不算0自网）有几个可用子网以及各自范围的可用和广播地址的问题弄个清清清清楚楚楚楚！！！！！ 到这里我考的题目我敢说基本都回忆出来了，而且已经努力试着找到了原题，除了子网划分的几个不一定是（但类似）。 弄了整整一个下午，现在都快21点了，去得去吃饭了。又累又饿啊！！！！！ 各位多看书啊，然后做做比较权威的题如testking，然后再看书，实验也要做，不要给你个命令你都不知道怎么是干什么的更不知道有没有这条命令。 No textbook can take the place of practical experience!命令敲敲你就记得了，更知道是干什么的。 对了，说一下，我喜欢网络安全，但是没有钱买资料，希望看过这个帖子的网友门能推荐一些CIW教材、录象以及幻灯片的下载的地方。谢谢！！ 最后祝各位兄弟高分通过！！！！！！！
