Starting Up CCIE Study Again

I believe I'm at a point in my career where I need to transition to the next level if I want to be a marketable engineer. CCIE R/S will be my first step in this process, followed by Data Center. I will be writing on each topic in the extended blueprint and using labs examples when appropriate. The 5.0v Written will be replaced by 5.1v after July. My goal is to be ready to take the written before July.
