I cleared the CCNA Data Center this week. It felt a little silly since I have been teaching NP level classes for Data Center for a long time now.
Thank you so much to 1ExamAMonth.com ! I purchased their practice exam for the 640-911 DCICN exam and that was the only resource I needed. This is like CCNA with some Data Center basics thrown in. It was strange to see questions about hubs and Token Ring in a Data Center exam, perhaps some technical editor was asleep at the wheel when those questions made the cut.
For the 640-916 DCICT exam prep, I used a beta copy of the 1ExamAMonth.com practice exam. It was excellent preparation once again. I felt very comfortable with this exam, since again, I have been teaching the NP level courses. This exam was a bit more what you would expect from Cisco on the CCNA Data Center, although I was pretty annoyed with a bunch of questions that would require a candidate to memorize facts out of the product catalog for devices and modules. Fortunately, if you know your stuff, there are not enough of those questions to fail you in this exam. These questions were derived from the product tour sections of the Official Curriculum, so be sure to generate some flash cards from those materials. I expect the final exam prep product from 1ExamAMonth.com will also provide adequate prep on this information. Remember with the 1ExamAMonth.com practice exams to pay close attention to the explanation of the questions and not just the questions themselves.
Best of luck to all of you in this pursuit!
