This site was designed to help you pass the current CCNA 200-301 exam, but it can also be used as a reference for anything networking related. You’ll find all the materials needed to study for your CCNA exam here.
On the left side (or below on mobile) you’ll find a list of articles covering all the exam topics, organised into chapters. The first couple of chapters describe some basic networking terms and devices, the later chapters go a little bit more in depth. You can start reading the articles from the beginning to work your way through the exam topics in a logical manner, or you can find a specific article that interests you.
So what are you waiting for? Choose a topic and start learning! We wish you luck!
