The gold content of the certificate has not declined, but with the updated version of the certification, the increase in the knowledge of the test points more challenging, except for the memorization of the TK's, no matter how to say, Cisco's certification is the largest number of participants in the IT class certification. Really interested in Cisco certification and knowledge to go to the test, if you want to find a job through this certification or promotion and salary increase, there is no problem, there really is not much doubt. Have not begun to learn to start worrying about this certificate is not worth the money, might as well use this time to read more books.3 In my opinion, for the time being, Cisco certification is still very necessary to test, because many companies are still in demand for this type of technical personnel, if you have some other linux or server technology, then the career path will be smoother! The first thing you need to do is to learn how to use it. Don't think too much, because learning anything is a lot of people in competition with you, unless you can invent an industry out.
