- Learning Route
The content of CCNA certification is not difficult and you can learn by yourself. You can use the simulator to do experiments at this stage.
Although the content of the CCNP certification exam is a little difficult, there are a lot of relevant resources on the network. Most experiments can also be practiced with simulators such as IOU / GNS3, so self-study of CCNP certification is also feasible. As for learning materials, it is recommended that those with strong learning abilities first read Computer Networks by Andrew S.Tanenbaum, then find CCNA-CCNP videos to watch and practice more according to the experimental manual of CCIE network engineers.
Why do I emphasize that candidates should read the Computer Networks first? Because it can help you lay a very solid theoretical foundation and improve the efficiency of later learning. On the contrary, the theoretical teaching of Cisco courses is a contradiction: the theory in books has both depth and breadth (just mention it), but the whole network knowledge system is not well built. The introduction of the seven-layer network model in CCNA textbooks (such as the four books of Cisco Networking Academy) is too superficial. Many important knowledge points are not well explained. Only a few terms are mentioned, and the relationship between many knowledge points is not clarified. The later in-depth study, as of the CCNP textbook, mainly focuses on the in-depth analysis of specific technologies/protocols in the network, such as BGP and OSPF protocols (CCNP certification mainly includes layer-2 switching, layer-3 routing, IPv6, multicast, and specific configuration methods). Sometimes it is too detailed. When learning the CCNP textbook, you may find that you have to study a protocol in detail before having a clear understanding of the whole network framework. It is usually difficult.
2. It may be a little hard for you to learn for CCIE certification by yourself. The benefits that training institutions will bring to you can be divided into several parts. 1 Good teachers. It is suggested that you must find good teachers to teach you; otherwise, you might as well study by yourself. 2 Equipment. At the CCIE certification stage, you need to rely on a real machine to do experiments, but in fact, you can rent the real machine online, which is not expensive. 3 CCIE certification question dump. It is this magical question dump that leads to the extremely high passing rate of CCIE certification, and the cost will not be too high. 4 New friends. Students you get to know in the process of learning are an invisible amount of wealth.
3. The significance of the CCIE certificate in China is very special. Cisco’s official website has a large number of good English learning materials. If you want to reach the corresponding level of CCIE experts in both theory and practice, you must learn and absorb these official resources, which take a lot of time to precipitate. But few CCIE certificate holders in China really study these materials systematically, and not many people can pass the computer exam without the help of the CCIE certification question dump.
The original goal of the CCIE certification program was to train engineers with certain networking experience but a lack of thorough understanding. For students, I personally think that as long as they spend about 2 months carefully reading the above-mentioned masterpiece Computer Networks and then study for around a year to prepare for the CCIE certification exam, they are very likely to pass CCIE certification.
