Talk back to Nantian's circle of friends

Be familiar with Chinese learning guide, learn network foundation, learn TCPIP protocol and subnet division, learn routing protocol, do more CCNA experiments, and learn examination question bank.

The original textbook of CCNA is English. It is still difficult for us to read English textbooks directly, so we can learn from Chinese textbooks. The most important thing to learn CCNA is to master the network foundation, because other routing protocols may be forgotten after a long time, and only the network foundation knowledge will be remembered for a lifetime. It is also important to understand TCP/IP protocol, which is inseparable from our daily life. For example, our commonly used routers, switches, servers, etc. all have corresponding positions in the protocol, and TCP/IP protocol can quickly help us define problems when dealing with faults. Segmentation may be a difficult part for beginners. There are corresponding problem-solving skills in the textbook, so long as you master them skillfully and practice a lot, you can still master them firmly. In the routing protocol of CCNA, the configuration methods of RIP, EIGRP and OSPF are introduced, which are the basis of building a large network and should be mastered carefully. The experiment of CCNA is relatively simple and can be easily mastered through the experimental guide and simulator. Pay attention to doing more experiments. On the premise that there is a question bank in CCNA exam, most students can easily pass the exam. Because the question bank is in English, you may need to look up the dictionary in the first few times.

For some students who have no foundation, attending training courses is also an option, because training courses are generally free, and you can listen to them several times, each time it is an improvement for yourself. At the same time, having teachers' guidance and classmates' communication will also be of great help to your study.
