Tips and Tricks to pass the CCNA exam!

Welcome to eConfigs.com - your one-stop online Cisco CCNA exam resource. If you are new to Cisco exams and the CCNA, learn all about it in the What is the CCNA section. Before you get into the core material of the exam, you should visit What to study to learn exactly what you’ll need to know. And before doing any configurations you'll want to read the Getting Started page.  Right before taking the exam be sure to review my CCNA Test Taking Tips!

The information on this website is generated primarily for the CCNA 200-125 track. However, there is a lot of cross-over between all exam tracks which this information can also prove very useful for.

Below, you’ll find a list of various tricks and tips that will help you with your CCNA Exam preparation, as well as study notes for each of the exam topics that you should definitely understand. Please don’t be afraid to ask questions or post comments here on the site. It’s the people like you getting involved who have helped to shape the material on this website to be as great as it is, not me! Also, subscribe to my youtube playlist where I post CCNA configuration videos and check out my recommended study materials!

If you ever have a question about anything CCNA, feel free to ask me!

Cheers, and good luck! - Joe
