Hey folks. I received my GCIA earlier this year. Did fairly well on the exam. I was pretty happy with the knowledge I gained from it but I don't use those concepts or tools regularly at work and that knowledge has quickly faded. So now I have this cert on my resume but I feel like a bit of a fraud because I would probably fail that test if I took it today. So, short of reading all the material again, how do you all keep up on the knowledge and skills that you gain from these certs?
