First of all, the answer: you can learn, but in terms of the difficulty of Huawei HCIE, it is very difficult to get this certification successfully with zero foundation. Whether it is a school student, or changing careers, now learning HCIE certification more and more people, resulting in more and more novices today, whether it is self-study Huawei certification to enter the post or through the Huawei certified HCIE training institutions to learn to find a job, more and more people want to become a HCIE certified technical personnel, to a certain extent, reflecting the Huawei certification employment prospects have been hot. This is a self-study digital pass, organize the knowledge base a, what is Huawei HCIE, Huawei HCIE difficulty is how much? HCIE (Huawei Certified ICT Expert, Huawei Certified ICT Expert) is Huawei certification system in the highest level of ICT technology certification , aims to create a high gold expert certification, for the technology convergence in the context of the ICT industry to provide a new HCIE, as an expert-level certification in Huawei's certification system, requires candidates to pass written tests, LAB exams, and expositions, and only after passing a number of "hurdles" can they ultimately obtain the HCIE certification, and the difficulty of which is another indication of the certificate's The difficulty is also another aspect of the certificate's gold content. Huawei certification is the most difficult is that it is required to a large number of real operations, the need for hands-on ability, so you need to spend a period of time dedicated to learning, Huawei's equipment, how to operate, how to configure as well as real project cases how to do. Huawei hcie certification can be said to be the Huawei system inside the most difficult, get the certification also represents that you are Huawei certified network engineers inside the technical experts, generally this expert level salary in the whole Huawei network engineers inside is also the highest. Uncle Yun strongly recommended that if you want to get Huawei certification, network engineers want to engage in this aspect of the work of technology, then you have to Huawei Certified HCIE as your career development goals, one is Huawei, the manufacturer's market share share is large, and Huawei's reputation is enough to cover the development of you in this industry. Second, zero basis how to learn Huawei HCIE (a) to confirm the direction of learning Huawei HCIE to put it bluntly is the following steps. Confirmation of the direction of HCIE certification - - Understanding HCIE certification exams - - Selecting HCIE certification learning methods - - Taking the HCIE certification exam If you do not know what direction to take? It is recommended that the number of pass/routing and switching - especially the number of pass, belonging to the Huawei certification to lay the foundation of a certificate, do not know what to learn, first of all, the number of pass to learn, for you to learn the bottom of other technologies. (B) exam review 1, whether to enroll in a training organization on whether to enroll in a training organization on this issue, it can be said that the benevolent see benevolence and wisdom. My suggestion is that if you have limited time, limited energy, and is 0 basic want to learn HCIE then it is best to find a training organization. Institutions can provide you with a lot of help in exam appointments, textbooks, and review progress. So either don't enroll, or if you do, you must choose a reliable organization. This is like a driving school, although the self-test is possible, but there is no one to help, the examination process may not understand. 2, written test written test is the first step of the HCIE examination, compared to the subsequent exposition and experimentation, the written test examination is the most simple, the most easy. But from the written test, you will formally embark on the journey of HCIE exam. Therefore, this step, can not be in a hurry, to walk steadily. Before the written test, it is recommended that you do not rush to memorize the questions, but to find ways to re-examine all the knowledge content systematically. As the saying goes, "Sharpening the knife is not a good idea", if you have participated in the training of the organization, at this time you should watch the video or information given by the organization, and then begin to memorize the questions. Generally, this process depends on the different foundation of each person. Those who have a good foundation may finish watching all of them very quickly, and those who have a slightly poorer foundation may take a little longer. But remember, don't be anxious, don't be anxious, don't be anxious. Be sure to calm down and slowly read through all the knowledge points. Then, start memorizing the questions.HCIE written test question bank from the current collection of various institutions, less than 500 questions after the de-weighting.500 questions, the driver's license than the subject of a question bank is less. Since there will be many questions in the written exam that will make you doubt your life, about 20% of the questions will require instant memorization. Therefore, don't take more than 7 days from the time you start memorizing the questions to going for the test, you will definitely forget them after a long time. Suggestions, 7 days in advance about the test, about the test and then memorize, properly in time. 3, experimental examination 3.1, booking experiments due to the written examination is in the VUE (a test service provider, in addition to Huawei can also be examined by Microsoft and a bunch of other various exams) to carry out, so the results of the synchronization from the VUE to Huawei requires 3-5 working days. After the completion of the written test, you can rest for a few days, after you can book the laboratory, you can book the laboratory test on Huawei Talent Online by yourself, or you can look for the teacher of the organization to book for you. 3.2, LAB laboratory preparation first prepare for the LAB, and then prepare for the TS, and then finally prepare for the TAC. the preparation skills for the LAB test is to do more experiments, the basic rhythm of the time is two weeks, one week to get the T1, a week to get the T1.5. HCIE experiments, for engineers with a better foundation, the technology itself is not difficult, but the amount of configuration is very large.3.3, TS experimental preparation according to the experience of HCIE certified big brother has been summarized in the TS experiments with the way. The first time do not look at the answer, they go to the wrong, even if it takes a whole day, it does not matter, but do not look at the answer. This first time, no matter what, all the faults should be adjusted through, even if you go to Baidu, to check the product documentation, but must solve the problem. Then, go back to see the answer. At this time, focus on the following two points: 1. which hidden faults have not been found before. 2. which faults have problems with the solution. After this one time of TS, you basically get through TS. Then before the exam, have time to knock TS again, no time to take out the TS solution document, look at two eyes to recall.3.4, TAC experiment preparation TAC itself is not technically difficult, but the examination of candidates on the ability to write documents. For students who usually write reports and documents frequently, TAC basically do not have to worry about. If you usually write fewer documents, it is recommended that you read the standard TAC sample before the test, when the test directly memorized. Here insert a sentence. Although the TAC in the test, we have a lot of test-taking skills. But the document this thing, in the daily work is also very important. I suggest, no matter how the test, usually summarize more, record more, write more notes, write more documents. This will be very helpful to your future career development. 4, thesis statement now come to the point! HCIE exam has been a new version of the abolition of the interview! The new version of the exam is a new exposition, you do not need to face the examiner, just need to write out the exposition questions. Discussion of the problem is the basic theoretical knowledge, the same is a question bank is, more memorization is good.
