IT industry provides a lot of jobs with high salary and this drives lots of job-hoppers taking part in the training courses to be a professional computer worker with a certification.However, misleading information leads many people astray on their road.

Mistaken idea 1: certification means the passport for getting into the IT sector.Because of the deficiency in the supervision of the training market by the related departments, more and more certification examinations like Cisco 642-845 test appear and the number of people who pass such examinations have increased dramatically, which makes the former objective measures and value of these certifications are being lost more and more.

Misunderstanding 2: Accumulate the experience after obtaining the certification.It is not important that how high your salary was in your previous job positions, it is better for you to keep in mind that you may have to start from scratch, and enter the computer industry by paying the price of cutting your own salary.

Third, The more certificates, the better.Too many certificates do not reflect the expertise of job seekers, instead they make employers feel at loose ends and cannot decide what kind of job is fit for each.

Mistaken idea 4: buried in the books for certification without even a glance at the market demands.The social demands for the certificates are changing all the time, if one cannot grasp the correct trend, he would pay in vain.

Misunderstanding 5: Only focus on input, and ignore output.Textual research is an educational investment, especially to pass the 642-845 exam. Students should also evaluate the investment benefits on both economic and time.It is a realistic problem for students to choose a right certification according to their economic power and time.
