CCNA stands for Cisco Certified Network Associate, and is a certification in IT handed out by Cisco after an exam.
Now, in order to get the CCNA, you’ll have to study and read through a few books which Cisco itself publishes. But the information can be quite hard to comprehend and retain, especially if you’re new in the IT field. To that end, you can now use the free CCNA study guide to better organize, memorize and understand the information needed to pass your CCNA.
The guide (linked above) is very neatly organized, giving you complete control on what areas you want to go deeper into. There are chapters and links to lots of resources which can make the whole experience not only a productive one, but a comprehensive and, at times, fun one as well.
So if you’re looking for a great CCNA study guide, you should definitely give the one that’s linked a go. You won’t regret it!
