Things are moving along slowly. I feel that writing a blog post with notes slows me down, so I’ll probably just post updates, on how things are going. Currently, I’m working on finishing up VPN, as that really is my strength, and then work on other things. It seems that the passing score of the CCIE security has also been reduced. Good for me! Less time spent on the written, gives me more time for the lab.
