I am trying to see which would be better for me to learn. I have my CCNA so I have worked with switches and routers for testing purposes. I haven't touched PIX yet and was wondering if I should learn that as well? I know Cisco is used in large companies and I want to make myself marketable if I should apply for a job. I am looking for suggestions and if you don't mind, please suggest a Cisco product that you would recommend for me to use for testing and learning purposes.
