Please note! The network engineer in the routing and switching direction mentioned here is exactly a real engineer! A true engineer who can truly solve the problem!
1) English ability
The concept of “network” is not what we propose, but it originates from overseas. Plans like network infrastructure are made by foreign countries. Although our technology is constantly improving, many advanced materials are also available in English. If you do not have good English skills, it will be difficult to become a qualified engineer to understand and research advanced technologies. So, to become a qualified engineer, English ability is a very basic ability;
2) Learning ability
For example: If I were a network engineer at a company, I started with a simple network using simple network equipment such as Layer 3 switches, Layer 2 switches, and routers. The knowledge of CCIE used is relatively small. This network management is naturally very simple. My daily work is pleasing!
Later, the scale of the company has expanded and the simple network architecture has obviously failed to satisfy the company’s needs for the network! As a result, we added a firewall on the exit, and made security controls on the internal network. Since so many new things have been added, it is natural that I need to learn more.
Later, the scale of the company has expanded, and the company frequently receives many visitors. In order to entertain these visitors, we have to open some of the company’s networks to them. As a result, our company purchased a set of wireless devices, such as wireless controllers. All of a sudden, I have something new to learn!
I am the company’s network engineer. If the company needs to put in a new set of software equipment internally, I have to complete other things to ensure the smooth flow of all kinds of traffic!
It is not difficult to see from this example: The network is constantly evolving, and the technology that network engineers need to master is also increasing! Especially when the application is more and more complex, the situation is changing! If your technology remains the same and you do not have a good learning ability, then the road ahead will naturally be narrow and narrow!
3, three suggestions for beginners:
1) They must learn to find information and do “reach the party” without moving! Try to see similar English learning materials on the basis of reading Chinese materials! While deepening one’s own technical ability, it can also improve one’s English ability, killing two birds with one stone;
2) Do more practice and avoid eye masters! Network engineering is a kind of very practical technology. It can be said that many more are useless. It only depends on the actual operation. On paper, there is no value in this field! Many engineers think that this technology will, I know, but actually touch nails repeatedly in practice. This is the result of not doing much more!
3) Join some communication platforms to ask questions that you don’t understand, and speak up! Not only can you deepen your understanding of your known knowledge, but you can also learn more under the guidance of others!
CCIE R&S is a very good direction in Cisco certification and it is a direction worthy of its own efforts and efforts. When you truly pass the CCIE R&S certification, you will realize more!
