ccna備考心得（CCNA preparation experience）

1、ccna備考心得（CCNA preparation experience）Successful one:The exam is not difficult, mainly to understand the knowledge, understand you will feel very relaxed after the exam.Choosing materials is very important to the success of the exam. If you take part in training, it may not be a problem. If you teach

2、 yourself, it will be critical. You need to get the official data of Cisco Press, you need to collect widely, to understand the CISCO examination involves a wide range.Learning and learning process should pay attention to methods, more importantly, need perseverance, if you have relevant work experi

3、ence, learning may be easier, otherwise, you need to pay more labor.The test is the test of your learning, but also the most critical. You need to adjust your status. Keep your confidence in exams. Dont give up until the last question. In the exam, you will encounter something you are not familiar w

4、ith, or even have not touched at all. Dont be nervous. Because you do not want to get full marks, the important thing is to test every topic you know, if you know the wrong topic because of the wrong, do not know the wrong, then the consequences will be silent.With regard to exam simulation question

5、s, after fully mastering the basic knowledge of certification test, simulation questions can only help review the knowledge points in a random way.Winners two:CISCOs textbooks are the best and most authoritative. The examination materials are based on CISCO. A book must be carefully read, not a fluk

6、e. The concept should be clear, the same question again! Strange, also will not deviate from the principle. Look at the original CISCO book, if the network foundation is good, do not look at the Chinese version of the book.Cisco options each were easy to fuzzy and uncertain, if not very clear on the

7、 concept such as some of the details, see his options are easy to feel each say are justified, it is not easy to choose. So in the preparation must be full of key concepts and materials mentioned in detail to give attention in the choice is to have confidence in their own memory, do not change their

8、 first choice at random. Another focus is the IOS operation, the command will set out to let you choose, remember some of the habits of the IOS command the general syntax and order of parameters is relatively easy to choose. The last point is not backward in the examination, after the end of one of

9、the problems is no longer look back, so we must understand the questions and see the problem, the key problem is that he is describing a scene is not a problem, the key point is the essence the problem, he will not use clear language to tell you to rely on this concept, but look the other way, but t

10、o choose the right answer to see its key concepts actually designed to. The whole examination time is very abundant, 105 minutes 65 questions, generally 40-50 minutes can be completed, but still that sentence, careful and careful.Winners three:. Think about it later, the whole review process, mainly

11、 three things.1, Sybex CCNA 2 640-507 Study Guide, is absolutely a good thing, need to read carefully, especially to understand the basic concepts. Each chapter after the Hands on Labs must be hands-on, familiar with its results.2, CCNA requirements for Cisco private operating system IOS (Internetwo

12、rking Operating System) have a more in-depth understanding and understanding. A Router Simulator (simulator) is very necessary. Good Router Simulator a lot, such as the authorized Sybex Electronics Industry Publishing House of the CCNA virtual laboratory is very good, can a virtual simulation enviro

13、nment (two 2600 oil and a 1900 switch), to obtain practical experience the configuration of routers and switches.3, Boston exercises, before the exam finished 3 sets of CCNA test questions, probably more than 600 bar, mostly concept questions, and the actual examination of the title is very familiar

14、, harvest a lot.The most critical thing is to put the Sybex CCNA Study Guide back seven times, the topic has repeatedly done three times,It seems like more than 500 questions altogetherWinners four:The following books are good reference materials, you can come and see:One is Cisco Press (CISCO Press

15、) Cisco CCNA Exam #640-507 Certification Guide author Wendell Odom.Another book is SYBEX Cisco CCNA Certified Network Associate Study Guide. published by the companyThere are also 4 reference books in China, usually in the big computer bookstore:This is a Cisco CCNA certification exam publishing gui

16、delines (640-507) * (this is Cisco Press Cisco CCNA Exam #640-507 Certification Guide translated into Chinese books on English not good person is a blessing. Another three are the CCNA learning guide, Cisco and IP addressing, and Cisco IOS IP technical guidelines for the mechanical industry press.As

17、 for routers, I like RouterSim2.0, and I think its pretty good for CCNA. The exam simulator is the best of BOSON, Boson Router Test3.38Winners five:Sum up, have the following experience:The OSI reference model, TCP/IP model has a good grasp; used CISCO low-end router; switch operation function has s

18、ome basis;Before the exam, I looked at Sybex, which was strongly recommended by netizens, and did about 50 Boson3 questions as a warm-up. I feel Sybex should be the end of each chapter of Review question to see if it is necessary, for the CCNA exam, not afraid of is not refined, but not enough to le

19、arn the fine, do Review question, you can check whether all the key see. In addition, I think dont spend too much time to do CCNA PTC, of course, to increase knowledge is good, but this set of questions for the exam didnt help - I think CCNA exam questions are very straightforward, the answer is ver

20、y clear, not around the people like PTC. I suggest you look at Cisco and network technology website CCNA 160 questions as a summary review. I dont repeat the rest. Winners six:Some suggestions:Honestly, boson simulation problem difficulty is low, but knowledge is relatively clear, the exam will not

21、like the boson problem as a naked, is light to see options you can know the answer, that is simple, the real questions may be the subject of boson 2-3 topic knowledge points in a merger a problem, but the answer would be more obscure, do not understand do not understand the knowledge or not seriousl

22、y look at the subject, it is impossible to choose the correct answer, the real test, interference or have a certain strength, so I hope when we review, to review it carefully, coverage large, but there is no need to delve too deeply into some parts of the CCNA exam requirements, always just stay in

23、the primary level exam well, from http:/cisco- and / the 2 mirror?. Intestinal he Nqingdong webmaster to me particularly helpful, examinee experience and cheet sheet download, test simulator! Feel WAN, ISDN and FRAME RELAY have done a lot, always is hot ah, add up to 8 -9 probably have questions abo

24、ut it.There are SYBEX the book, the book of WRITTEN LABS and HANDS-ON LABS have to look carefully and do until it feels natural to you. (the original author of SYBEX book)Winners seven:First talk about the choice of teaching materials, Im looking at SYBEXs CCNA Study Guide Second Edition, has seen t

25、wo times. There is a use of Cisco Press is out of the official textbooks, because of the things described in the exam from textbooks in the original sentence, a look ahead to save a sort of feeling in reading comprehension test. And，I have to say that Sybexs Guide is now full of incomplete knowledge

26、, for example, I have two ISDN Protocols (E-series, I-series, Q-series) problems, and Guide does not deliberately emphasize. In contrast, the official textbooks are very authoritative, but they are all over, and CCNA does not test all of them. In my opinion, Sybex Todd Lammle written more vivid and

27、humorous, feeling tired, while the Cisco Press wording is so written, looks very boring! Fortunately, Sybex Knowledge is not clear only this one, but also the remedial method, so choose Sybex to focus on learning, but in the role of review of each layer of wide area network knowledge, OSI and do exe

28、rcises when they encounter problems to see Cisco Presss official textbook.Also speaking about the preparation for the exam, the test must be read Guide, the length of time spent varies from person to person, depending on the work environment. The experiments at the end of each chapter must not be ig

29、nored, and should be done one by one in the simulation router software. I recommend Boson simulation software RouterSim CCNA 2, CCNA basic command examination involved are no matter themselves OS interface design is very realistic (once I practice in the company with this software review by colleagu

30、es by mistake in the operation of the router, it also asked me which one is modified). After all, even if there is experimental conditions, no one would dare to do the experiment and wantonly change in the operation of equipment. I feel ready to have seven, 80% of the time you can do simulation prob

31、lems, analog exam software, I recommend Boson Router Test 3.09. To do this simulation problem with the original title of dont see, but to test their knowledge is full (in front of that Sybex fall ISDN Protocols is found in the Boson problem of Boson), a total of 12 sets of questions, each with 56 or

32、 58 questions, knowledge points are overall, and in his Practice Test #3 even very similar to the original title of the title appears.Do it to a put a finish, and Live Scoring, Back Button, Show of Ansowers # do not choose, if they cant decide the subject, put down this title, subject to the wrong t

33、opic due to their cooperative concern, according to the correct answer and the prompt analysis what is your problem, if you still dont understand and go to see the Cisco Press above what is said (rarely used Cisco Press materials and there is no place to buy a necessary to find some people borrow th

34、e electronic version of it). Before exams, look at SHEET200, it still has a lot of the original title, can enhance the confidence.Winners eight:Cisco web page to provide blueprint to see, can not bear luck, Cisco document CD on the network theory part to see, look at the process should pay attention to comparison. IOS has many. The most annoying is that there are two VLAN problem one is given several shows to determine which use the VLAN, the other is about the fram tagging, which I didnt see only a few questions, it should be said that the more difficult exercises, as Tim is ROUTER RIP EAS
