CCNA clearance cheats, 10 Cisco training Experts ' wisdom

i am the 51CTO lecturer Kanhaijiang, at the Institute 11.11( People's IT Learning Festival) Come on the occasion, and everyone to share my CCNA customs clearance experience. The text is coming ~ ~ ~

in writing this title, I seem to have returned to the original to learn Cisco Qizaotanhei, but a fun time. Obviously, I am definitely not a network genius, no extraordinary talent, even at that time even a computer belonging to their own elusive, so in the study of Cisco courses, especially learning CCNA The process, quite hard (first boast about), but also accumulated a number of personal learning experience, today write down, to share with you, but also hope that everyone's learning can play even its small role, I will be very gratified!  

      in deciding to learnCiscoafter the course, the first question that people encounter is whether or not to attend the training, because after allCCNAthe training fee, especially the examination fee, although noCCIEcertification is so expensive, but it's not a small sum for students or ordinary working-class people. From my point of view, if you are not gifted very high, self-control is very strong, under the premise that the conditions allow, the proposal should still participate inCiscoStandard Training. That's not because I'm a teacher at the training center because asCiscoThe most basic certification, only after the training, you can less detours (this is very important, otherwise it will greatly affect your confidence), to understandCiscoThe core idea of the certification system, can be more quickly find their own learning methods and development direction, which for later self-study other Cisco courses, the role will be very large.

CCNA Although it is Cisco entry-level certification, but the content is more, more miscellaneous, for beginners, the difficulty is still relatively large, I believe that even if you are learning computer, most people do not have so detailed research ROUTE or SWITCH . After all, this is a professional thing, not to say it will be used, but also to understand how it works.  

so CCNA What are you going to learn? Unlike most Chinese textbooks on the market, my understanding is that CCNA mainly contains the following 5 parts (which is also the order of my lectures):

1, The basic principle of the network, this part contains a lot of trivial knowledge points, at the beginning of the time will feel very dull, no way, do the technology will have psychological preparation, you want to want a girl, you have to pay, you want to love a girlfriend like a router, switch, firewall, and also foot more than a boat, Also must often hate, the faithless ...

2,two-layer Exchange technology, this section mainly introduces the principle of Exchange and Networking mode,including two-layer switching campus Network common technologies:STP,VLAN,TRUNK(as a result of the newCCNANo, I don't speak .VTP, it is not listed) (is also the most practical part of the campus network engineers who feel personally);

3, three-tier routing technology, which focuses on common routing protocol principles and configurations (including static routing, RIP , EIGRP , OSPF and so on;

4, Web applications, including DHCP

5, knowledge extension, this part of the content is every CCNA The most important part of the revision is basically to introduce and understand some current mainstream technologies, such as IPv6 , Internet of Things, cloud computing and more.

    This appears to be ---- ---- ---- ---- ccna

As for the teaching materials, many students asked me whether they should read Chinese textbooks or English textbooks. My advice is, forCCNA, it is best to use Chinese textbooks,CCNAin China hasNover the years, Chinese textbooks have been quite mature, the use of Chinese textbooks can improve the efficiency of reading, but also can reduce some additional burden (especially psychological). Because from me thisTenyears of teaching experience, most doIT, English is a difficult problem. But if your English reading ability is very good, since when conceivable. On this point I need to specifically explain, if you are interested in the network field long-term development and achievements, English reading is to have to pass, many computer or network technology books are translated from abroad, in view of the different levels of translators or need to query the latest technical information, you have to view the original English technical documents, For example, the Cisco official website is the best learning database.

     for after all, the interest is the long-term motive force of studying hard. In the course of theoretical study, the teacher explains every knowledge point to really understand, can not smattering, only the real understanding can extrapolate. In the course of teaching, I often give students to do some The topic, in fact, the knowledge point is

    forCCNAis the experimental part, how to emphasize is not too, inCiscoThe ability to solve problems is particularly important in the certification system, which also reflectsCiscoexam, although most of the choice, but almost to simulate the reality of the network scenario-based. I advocate to understand the theoretical knowledge point in the experiment and test the theory by experiment. In class when the teacher under the guidance of the use of real equipment, experience the feeling of holding it ... The simulator can be used under class, now the simulator is very good, with the realIOSimport, and real machine almost no difference, the most commonly used are:Cisco Packet Tracer, industrial Darip,GNS3,IOUand so on, these simulators each have the advantages and disadvantages, can alternately use.

seems to have written a lot, and then write down is in the test everyone's endurance, about the test I will write another article and communicate with you. Finally, I wish everyone in the it Sky, make contributions, create their own territory! Also welcome everyone in the study, life confused or confused, by any means and I contact, I will do all the ability to help you!
