Hey guys! I'm taking a course this semester on Networking Fundamentals. Our professor has given us the opportunity to be able to take tests by Cisco to become CCNA certified for free. I don't know much about networking yet, so I was wondering how much of a big deal it is to be a CCNA certified person. I have heard taking these exams elsewhere is really expensive, so I though that giving the extra effort outside of the course (CCNA tests are not mandatory, just optional) might be worth it. What can you guys tell me about this?
