The experiences of successful users are undoubtedly very important to us, because they not only know the road to success, but also know the road to failure, these experiences are of great reference value to latecomers. Friends who have already passed ccna are very willing to share their experiences with you.
Some netizens collected some experiences and sorted them out, hoping they could help those who are preparing for the ccna exam.
It is not difficult to test questions. It is mainly to understand all the knowledge points and you will feel relaxed after the exam is understood.
Selecting materials is very important to the success of the exam. If you attend the training, it may not be a problem. If you are studying by yourself, it is critical. To get official Cisco press information, you need to collect it extensively and understand that the Cisco examination is still quite wide-ranging.
You should pay attention to the methods in the learning process. What is more important is perseverance. If you have relevant work experience, it may be easier. Otherwise, you need to pay more work?
Exams test your learning and are also the most critical. You need to adjust your status. Be confident in the exam and never give up on the last question. You will definitely encounter something you are not familiar with or even have never been familiar with during the exam. Don't be nervous. Because you do not want to get a full score, it is important to test every question you know. If you have made a mistake on the question you know because of your carelessness, you will also be wrong if you do not know it, then the consequences will be left blank.
After you have fully mastered the basic knowledge of the certification exams, the simulated questions can only help you to review the knowledge points in a random way.
Cisco textbooks are the best and most authoritative. The exam materials are subject to Cisco. The book must be carefully read, so there is no chance. The concept should be clear, And 'everything changes forever '! The question is strange and will not deviate from the principle. Read the books of the original Cisco version. If the network infrastructure is good, do not read the books of the Chinese version.
Every Cisco option is easy to blur and uncertain. If it is not very clear about the concept, for example, some details, it is easy to feel that everything is justified after reading his options, it is not easy to choose. Therefore, you must pay full attention to the key concepts and the details mentioned in the teaching materials during preparation. In the selection, you must have confidence in your memory and do not change your first choice at will. In addition, the focus is on iOS operations. commands will be listed for you to choose from. Remember that some habitual syntaxes of IOS commands and the general Parameter order are easier to choose. The last point is that the exam cannot be rolled back, that is, after a problem is over, you can no longer look back, so you must understand the question and see the question clearly, the characteristic of a concept question is that the situation he describes is not the key to the problem. The key is the substantive test point of the problem. He will not tell you in a clear language to rely on this concept, but will talk about it to the right, however, to select the correct answer, we need to see at a glance the key concepts it actually designed. The entire exam is very time-consuming, 105 minutes 65 questions, usually 40-50 minutes to complete, but still that sentence, carefully and carefully.
...... Later, I thought about three things in the entire review process.
1. sybex ccna 2.0 640-507 study guide is definitely a good thing to read carefully, especially to understand the basic concepts. The hands on labs after each chapter must be operated by hand to familiarize themselves with its results.
2. ccna requires a deep understanding and understanding of Cisco's private operating system iOS (Internetworking Operating System. A Router simulator (simulator) is very necessary. there are a lot of good router simulators. For example, the ccna virtual lab published by sybex authorized Electronic Industry Publishing House is very good. It can be used to virtualize a simulation environment (two 2600-way generators and one 1900-way switch ), gain hands-on experience in configuring vrouters and vswitches.
3. Boston's exercise questions: three sets of ccna questions have been completed before the test. There are more than 600 questions. Most of them are concept questions. They are also very familiar with the questions in the actual test and have gained a lot.
The most important thing is to repeat the ccna study guide issued by sybex seven times and repeat the questions three times. (It seems that there are more than five hundred questions in total !)
The following books are good references for you:
One is Cisco Press (Cisco Press) cisco ccna exam #640-507 certification guide by Wendell Odom.
The other is the sybex exam book ccna Cisco Certified Network Associate study guide.
There are also four reference books in China, which are generally used in large computer bookstores:
A Guide to the Cisco ccna Certification Examination (640-507) of the People's post and telecommunications Publishing House * (this is a book translated from the Cisco press Cisco ccna exam #640-507 certification guide into Chinese, it is a good news for people with poor English .) The other three are ccna learning guides, Cisco and IP addressing, and Cisco ios ip technical guides of the Mechanical Industry Press.
As for routers, I like routersim2.0. I think it is suitable for ccna. Test simulator is best for boson, boson router test3.38
To sum up, we have the following experiences:
Have a good grasp of the OSI reference model and TCP/IP model; have used Cisco's low-end routers; Have some foundation for the operation functions of switches;
Before the exam, I read the highly recommended sybex and made about 50 boson3 questions for warm-up. (if there are not many questions, just warm up !). I feel that it is necessary to take a look at the review question after each chapter of sybex, because for the ccna examination review, I am not afraid that I will not be able to learn well enough, but I am afraid that I will not be fine enough. After review question, you can check whether you have seen all the points. In addition, I don't think it's good to spend too much time on the ccna PTC question. Of course, it is good to increase knowledge, but this question is not helpful for the exam-I think the ccna questions are straightforward, the answer is also clear, and it will not be as confusing as PTC. We recommend that you take a look at the ccna 160 questions on Cisco and the network technology website as a summary and review. I will not repeat other items.
To be honest, it is difficult for boson to simulate questions, but the knowledge points are clear. The questions in the exam are not as exposed as boson's questions, that is, the answer can be known simply by looking at the options, simply put, a real question may combine 2-3 knowledge points of a boson question into one, and the answer to the question will be relatively obscure, if you do not understand the knowledge point or do not take the question seriously, you cannot select the correct answer. The true question and question have a certain intensity of interference items, so I hope you can review the question, can review carefully, the coverage is larger, but do not have to go too deep on some part, always ccna test requirements only stay in the preliminary level questions, from the http://cisco-net.myrice.com/and http://mp3.tzinfo.com/lining/the 2most ?...... Jing henqingdong helped me a lot. The examinee's experience was discussed, the download of cheet sheet, and the question simulator! In terms of Wan, ISDN and Frame Relay have won a lot of tests and have always been a hot topic. I'm afraid there are eight questions in total-about 9 questions ......
There is also the book sybex, the written labs and hands-on labs after the book should be carefully read and done, until it feels natural to you. (the original story of sybex)
Let's talk about the selection of teaching materials. I have read sybex's <ccna study guide Second Edition> and read it twice. Another article we will use is the official teaching material provided by Cisco press, because the descriptions of things in the question are from the original sentence in the teaching material. It is easier to read and understand things in the examination. Moreover, I have to say that sybex's guide has incomplete knowledge points. For example, I have obtained two ISDN protocols (e-series, I-series, Q-series) but the Guide does not emphasize it. In contrast, the knowledge points of the official textbooks are authoritative, but they are all too powerful. The ccna exams are all unavailable. In my personal opinion, toddlammle in sybex is quite humorous and doesn't seem to be tired of reading it. However, Cisco press's syntax is too complicated and it looks boring! Fortunately, sybex's <>
This is the only case where the knowledge points are unclear, and there are some ways to remedy it. Therefore, we should choose the sybex book to focus on learning, I just reviewed the wide area network knowledge, the role of the OSI layers, and encountered problems with simulation questions before going to the official Cisco press textbooks.
Besides, you must read the guide before preparing for the test. The duration varies from person to person and varies with the work and study environment. Do not underestimate the experiment at the end of each chapter. Do it one by one on the simulation router software. Simulation Software I recommend boson routersim ccna 2, the basic commands involved in the ccna test were all very lifelike In the design of the guest OS interface (I was mistaken by my colleagues when I used the software for review at my internship company to operate the router, I also asked which one I modified). After all, even if I had lab conditions, no one dared to modify the configuration of the running device to do the experiment. I think I can do the simulation questions when I prepare 7 or 8. I recommend boson router test. 09. do not look at the original question for the purpose of doing this simulation, instead, we need to check whether our knowledge points are fully mastered (the ISDN protocols that sybex fell out was found during boson). boson has 12 sets of questions, each set has 56 or 58 questions, and the knowledge points are comprehensive. In his practice test #3, there are even similar questions.
When you are doing this, you need to get all of them done, and live scoring, back button, show # Of ansowers should not be selected. If you encounter a problem that you are not sure about, you need to write down the question number. This type of question requires cooperation with the wrong question to attract your attention, and analyze your problem according to the correct answer and prompt, if you still don't understand what Cisco Press says (there are few places to use cisco press textbooks, so it is not necessary to buy one, find someone to borrow an electronic version ). Let's look at sheet200 before the exam. There are still many original questions above, which can enhance our confidence.
The blueprint provided on the Cisco Web page should be viewed and cannot be flustered. The document CD of Cisco should be viewed on the network theory part. The comparison should be emphasized during the process. There are many IOS apps. The most annoying problem is that there are two VLAN questions: one is to give several displays to determine which VLAN is used, and the other is about fram tagging. I didn't see how many questions I just did, it should be said that the difficulty is higher than that of exercise questions. If it is easy to add blank questions, it is router rip.
When I was preparing, I read sybex's Learning Guide and made a lot of questions. Keystone, PTC, and boson both made a sense that PTC's questions are too doggy and boson's are good, however, there is still a gap with the actual exam, and the actual exam questions should be more flexible. Routersim is useful for memorizing commands and modes.
Ccnp is not difficult. The most important thing is that you can read the CBT twice. All the content is mentioned in it. At the same time, boson has a good question and is recommended to you. It took me half a month to take each exam.
In general, Cisco's examination questions are more flexible. Although some of them are dead, the proportion is not large, the test mainly involves selecting a qualified command from dozens of commands listed in it. It is important to have a thorough understanding of various routing protocols, so as to avoid a thorough understanding. Otherwise, you will feel that you will not be able to choose from the exam, as if you were right. During the test, the content of the kernel and BGP is relatively much taught. Another point is that the outline of the exam must be closely followed during the review process to avoid incorrect directions.
