CompTIA recommends that you have A+ and Network+ certifications, and two years on-the-job networking experience, prior to preparing for this exam. We don't require that much. But you should have substantial knowledge of TCP/IP networking prior to signing up for this course. You'll also need Internet access, email, the Microsoft Internet Explorer or Mozilla Firefox Web browser, and the Adobe Flash and PDF plug-ins (two free and simple downloads you obtain at http://www.adobe.com/downloads by clicking Get Adobe Flash Player and Get Adobe Reader).
