EI's course content is mainly based on enterprise network architecture, but the new enterprise network architecture adds soft-defined SDN technology, and soft-defined SDN technology accounts for 25% of the test sites in the exam.
In the modification of the routing part, different from the old version of RS, EIGRP does not focus on learning, and only requires the learning of this routing protocol by "understanding EIGRP", in addition to OSPF, BGP It is still a must-learn content.
It is shown in the standard teaching requirements of EI that we originally focused on the CCNP course in the RS theoretical course, but now the CCNP of EI only requires 5 full days to complete, which also shows that Cisco believes that after Twenty years of RS technology promotion, CCNP popularity has been very mature. It is no longer necessary to spend too much time studying it, and more time should be devoted to the study of SDN new technologies.
In the detailed comparison of the two directions of cancellation and addition, it can be seen that the original knowledge system of RS retains about 50% of the existing knowledge system of EI, and the new The content is 25% soft-defined SDN technology, 15% security and features, 10% programming and other technologies.
It is not difficult to see through the knowledge system analysis of EI CCIE enterprise network architecture foundation, EI architecture is the beginning of the digital transformation of enterprise network, and automation and intelligence are ultimately the development direction of EI CCIE assessment.
In the soft-defined network, the requirements for the basic network architecture are getting simpler and simpler. However, this does not mean that network engineers should transform into programming. Even the policy formulation of the soft-defined network, the architecture design It must be supported by very powerful network technology.
At present, IE-LAB has developed a reasonable complete curriculum system based on Cisco standards. The EI curriculum is still from the shallower to the deeper, covering both the original RS knowledge system and the new EI new technology learning content.
We say that the enterprise network architecture is transforming from traditional to digital, and our learning methods are also undergoing a transformation stage. ITCertdumps will provide all learners with new development opportunities.
Holding IT certification requires choosing the certification, studying for the exam, and passing it. EveDumps could possibly be your finest ally if you’re considering obtaining a certification. Professional and real CCNP 350-401 Dumps at EveDumps, you will discover everything you need.
