I’ll start off by noting that I failed the 640-554 exam late last month. I found there was quite a bit of content which I either didn’t cover as much as I thought I’d need to, or the material I used to study didn’t cover the knowledge as deep as I needed.

After knuckling down and studying into the topics I felt my knowledge was lacking in, I passed my CCNA Security yesterday with a 93% and needed 89% to pass.

I’m going to take a brief break and then delve into some python and then CCNP R&S.
