Cisco CCNA = > Cisco CCNP = > Cisco CCIE, equivalent to network support engineer.

They are Cisco certified network engineers, intermediate network engineers and network experts, and their levels have improved in turn. Only by passing the certification examination at the previous level can you be eligible to take the Cisco certification examination at the next level.

Cisco CCNA test a book, mainly about the basic knowledge of the network, OSI seven-layer model, switching, routing and other simple debugging and installation. You can go to the bookstore to buy textbooks for review. Passing only one exam is the easiest to get; The examination fee is about 100 USD. All the questions are on the computer, and as soon as I answer them, I will print out whether the results have passed or not.

Cisco CCNP takes four books, the contents of which are more in-depth, comprehensive and more difficult on the basis of CCNA, and the corresponding four courses must be passed to get the certificate.

Cisco CCIE is the most difficult, which is divided into two parts: written test and operation. Relatively speaking, the operation is the most difficult, the examination time is about half a day, and the cost is about 1 ten thousand yuan. Because fewer people pass, it is more valuable. CCIE will be sent to refractive examination only if the written test and operation pass.

CCDA = & gt； CCDP corresponds to CCNA =>；; CCNP, the difference is that it focuses on network architecture and design, which corresponds to the position of pre-sales network support engineer.
