My name is Fred Warren. I am a Surveillance Technician and we upgraded our surveillance system to use Cisco 2960 Switches and a Catalyst 4506-E Main Core switch. I have recently completed the video training for the CCENT/CCNA certification and I am very nervous/excited to take the Certification Exam. I hear that it is not easy and that I could fail my first time. Any advice on how I could prepare for the exam?
