I have decided to go for my CCNA to help round out my routing and networking skills. Why a cert? I view certs as a way to organize my studies, enjoy learning, and set a level of achievement. Simple.
So far, my primary study method has been this book by Sybex; however, I will be purchasing some 2501 routers for the hands on exercises.
As it stands I am on my first reading pass. After complete my SANS training and testing, I will concentrate my studies on the CCNA. So far, I have enjoyed my new learning opportunity. I know it will be worth the effort.
