18 pictures tell you: 10 key technical points that a 90-point network engineer should master

"As a network engineer, what does it take to be qualified?"

Lao Yang believes that this is not just a confusion for working people in the workplace.

Network knowledge is a very important part of the IT industry. It would be great if we have more and broader knowledge besides the network.

But even if we don't want to admit it, we still have to face this problem: human energy is very limited.

• Mastering some technologies is a great help for network engineers;
• Some technologies seem advanced and impressive, but provide little support for actual work;
• Some technical points are even useless for certification, but you are still studying hard.

So, when it comes to network technology, what are the key points to be qualified?

Lao Yang specially compiled a detailed mind map for this purpose, and this time the high-definition version is arranged.
