How is CCIE DC practical and how difficult is the CCIE DC exam?

Cisco released his sixth CCIE direction - DC CCIE in September 2012. For a time, DC CCIE became a focus of network engineers. His focus is also on the hot technology of data center construction in recent years. This makes the Cisco DC direction technology the most practical technology available today.
The so-called most practical, first, the current Cisco data center concept is a leader in the industry, so it is emulated and compatible by many vendors. After learning Cisco DC technology, it is easy to understand and master similar technologies from other vendors in the industry. Second, the current Cisco data center related products are large in volume and are widely used in energy, finance, banking, education and other industries. The annual project level is in billions of units (billion). There are many data center projects, and there are relatively few technical engineers in the data center. This has caused the contradiction between current supply and demand of talents. According to statistics, engineers who are currently working in data centers have more than 30% higher average wages than engineers in other directions. Some companies even have an annual salary of 500,000.
Some people will ask data center engineers to be so well treated. It is difficult to learn related technologies.
In fact, the data center CCIE is not as difficult as imagined, even more simple than many enterprise second- and third-tier network applications. The reason is that the more core part of the network infrastructure requires more stable operation, simpler requirements, more mature technology, higher compatibility, and fewer features. Therefore, data center technology is more operational and better than other types of networks. In many cases, CCIE DC written 40-101 and lab Dumps vendors will package complex protocols into hardware chips to keep operations simple. The most important thing is that the value of data center level engineers is not in the command line, but in the understanding and overall control of the network infrastructure.
