Put some conclusions first:
More than 10 years ago, CCNA had an annual salary of USD 15000. At that time, it was very valuable to have these certificates / master these abilities.
CCIE is indeed difficult to obtain, but the difficulty is reduced due to the existence of question bank. CCIE is an expert certification. This certification is recognized as the most authoritative certification in the IT industry all over the world. It is the top certification in the field of global Internet working. In addition to the value, there are many differences among CCNA, CCNP and CCIE. The value determines the difference in the difficulty of obtaining them. CCNA takes one written test and CCNP takes three written tests. In addition to the written test, CCIE also takes an experimental test.
At present, various CCIE training institutionsprovide trial training, which can help candidates pass in a year. Then, the so-called [PaperCCIE] which is the mass production of CCIE is becoming more and more serious (in addition to the decline of CCIE itself, but also because the market demand for CCIE is slowly saturated). Cisco has also noticed these phenomena. The measures taken are to increase the examination cost and reduce the pass rate. Generally speaking, the value of CCIE Certification has decreased, and various low-qualitytraining institutions are massive. Obviously, CCIE trained by this kind of training institutions is not very competitive.
In any case, I strongly suggest that before learning the knowledge of CCNA-CCIE , candidates first learn the relevant tutorials of formal [Computer Network]. I strongly recommend the version of Andrew S. Tanenbaum. Then, you will find that you have almost complete self-study ability. You can go to Honghu Forum, 51CTO and other websites to find a lot of resources for self-study (including videos, theoretical manuals, experimental manuals and so on). There are still a lot of free shared materials of CCIE. In addition to having the ability of self-study, what is more important is that you have a comprehensive understanding of the whole knowledge system of computer network and really have the ability to judge which category of the contents contained in various CCIE directions belong to, the roles, the general network knowledge and something private to the manufacturer. (agreement, product characteristics, etc.)
Obtaining CCNA Certification indicates that it has the ability to install, configure and operate medium-sized routing and switching networks and troubleshoot. It can establish a connection with remote sites through WAN, eliminate basic security threats and understand the requirements of wireless network access. After obtaining CCNA Certification, you need to use the acquired skills in your daily activities, and constantly enrich your experience and improve your ability through work. As a part of Cisco certification network, CCNA Certification is something to be proud of.
For network engineers, it is necessary to obtain the relevant certification of Cisco. Cisco certified network engineers belong to the profession with strong technical specialty, and the shortage of certified talents is increasing rapidly with the popularization of China’s network. And the employment direction is almost unlimited, including data center engineers, network security engineers, enterprise network administrators, etc. With the accumulation of experience, you can be a project director, product manager, or engaged in R & D. A passport makes you stand out in employment and many other competitions. Cisco Certification is a highly prestigious network skill certification in the Internet industry. Obtaining Cisco Certification is undoubtedly a strong stepping stone to enter the network industry. https://cciedump.spoto.net
