Give some suggestions to friends who are just getting started or preparing to change careers as network engineers

My exam HCIE At that time, it was not called data communication , At that time, it was called routing switching .

My exam HCIE It's been many years , It has been many years since I became a senior network engineer . Recently, many fans who have just started and want to change careers to become network engineers have asked me how to learn and some suggestions for Huawei certification , Today, I have the opportunity to share with you .

No one is born a network engineer

Every network engineer is at a loss at the beginning , This is inevitable . If you just started or have contact at work , You will know that the concept of network technology is more abstract 、 Hard to understand , It's easy for many people to get started and give up by themselves . At the beginning, I suggest you learn about the network from the application , First of all, learn about the commonly used network devices , What are the functions of these devices , Learn how to use it . Understanding and using common network devices is the first step to become a network engineer .

Network technology learning is not achieved overnight

After knowing and using common network devices , We can learn the principle of data communication . In the update of Huawei certification examination this year , Routing Exchange （RS） It has been updated as data communication （Datacom）, Therefore, the learning and development of digital communication will become more and more important in the future . And learn the principle of data communication , First of all, we need to understand how the data in various applications we use communicate , Then learn and master the network technology .

Network engineer is a position that values Technology

Network engineer is never a position that depends on age , If you have enough skills and experience , In the whole career, it will only become more popular as you get older . So when we study , We must study the optimization technology of the network , For example, how to improve the performance of the network , How to improve network security and so on , These are your future hard power in the network technology industry .

Huawei certification suggestions for introduction to network technology

There are three levels in the Huawei certification system corresponding to network engineers ：HCIA、HCIP、HCIE, They correspond to the engineer level 、 Senior engineer level and expert level . As an examinee HCIE People who come here , In my submission HCIA Level technology can only be considered as an entry , To be competent as a professional network engineer requires HCIP Level of Technology . So I suggest that friends who want to engage in the career of network engineer can study and research first HCIP.

Network engineer system learning route

See here , You should have a general direction for the development and learning of network engineers . Below I will share a learning route of network engineer system , From understanding common network devices , To routing switching technology 、 To network security management , Following this route is enough for a professional network engineer .

If you need to get this learning outline of the network engineering system, you can like it directly + After paying attention to the private message （ Study ） You can get it ！

At the end

When I was a student, I often heard my teacher say ： There is never a shortcut to learning , Climb the peak step by step . Now I want to study network technology, too , I hope everyone can climb the peak on the road of network engineers .
