Importance of learning methods for CCNA

In Cisco's Internet world, the most elementary stage is CCNA. A lot of people think it's very simple. They don't learn anything. Isn't CCNA really very important and elementary? I think it's totally wrong.

We know that network technology is not difficult, but how to decompose some technologies into small knowledge points to understand and apply. If you apply it step by step with your study, you will find that there are many problems in your actual work, but the solution is very simple. When you put forward the solution, it leads to a number of problems. At the same time, the solution to new problems is very simple... In this way, one by one problems are solved, one by one problems are found again... Network technology will be improved Well, it's difficult because there are countless related problems and technologies waiting for you to solve and learn.

Cisco CCNA

Take VLAN as an example: problems arise from the conflict domain of broadcast domain and the waste of physical equipment in actual work. The solution is very simple. The logical division of VLAN on a physical device is enough. It's very simple to solve, but it also leads to the problem of data sharing broadcast domain in the same VLAN between different devices... The solution is very simple, just connect a data line on the port of two devices belonging to the same VLAN. But the problem is that when there are too many VLANs, every VLAN will connect to each other, resulting in a lot of waste of ports... The solution is very simple, do a testTrunk is OK. But the new problem is that it is impossible to distinguish the data streams in different VLANs. The solution is very simple. When the data enters the trunk, it is OK to add encapsulation. It seems to be perfect, but there are still problems. When the network increases, it is a big difficulty for administrators to do the same VLANs on each device. The solution is very simple, just do a VTP domain for unified governance. 

 

Is it difficult? It's not hard. As long as we know how the problem arises and how it should be solved. It's not difficult to sort out the whole idea. So the key of study is the problem of method.

CCNA practice exam is a way to teach you the basic knowledge of network and how to learn network knowledge. There are many people who don't care about CCNA and laboratory operation, but choose to study by themselves. But when they work, they find it difficult and don't know how to use it in practice, so they feel that they can't start when they face network work and network failure. This is that the foundation is not solid.

learning should be done step by step. Isn't there a kind of class that CCNP gives CCNA? It is a learning process from CCNA to CCNP, from foundation to practical application.

learning CCNA is very important! The important thing is that it is a framework and an outline for the future study of network technology, which guides us how to continue to learn more advanced network technology and lay a solid foundation for future study.

I hope more people will join the world of the Internet...
