This site was created to help you prepare for the CCNA exam. All the content on study-ccna.com is written exclusively for this site. Feel free to copy and distribute content, but please include a link to this site.
Some of the pictures on the site were taken from Wikipedia. Most of the examples are made using the Cisco Packet Tracer, a great learning tool. You can download Packet Tracer on the Cisco official website. Some network topologies were created using Dia, a free diagram drawing software.
We have put a lot of effort into this website and would really appreciate it if you liked us on Facebook. Thank you!
