Did Mark snow create a study plan for the CCIE DC track? I followed his plan for the CCIE R&S and i passed it on the first attempt not only that, I finished the config section within 3 hours and the TS within 1 hour.
I didn't create the study plan for R&S, Brian Dennis, Brian McGahan and Petr Lapukov did. I created the one for Voice/Collaboration.
We haven't published an official plan for DC yet, but both Brian McGahand and I have posted a number of times on what all materials we used, as well as what we've created and how we recommend you use it. I'll locate those posts and summarize them here in a few.
Brian's post on How I Passed the CCIE Data Center Exam can be found here.
Thanks Mark, I saw your CCIE voice plan. it's perfect, My wife will be following it. I like voice but my plan is to get the CCIE DC and SP first.
