Study materials:

-Practice exams
I spent about 1-2 weeks preparing for the exam which includes reading through the book and watching the course videos via CBT Nuggets. I enjoyed taking this exam overall. It's not too difficult as it's mostly just learning the terminology and determining the best case scenarios of what SAN/NAS solutions work best in different types of scenarios. My background includes data center, storage, and networking so that definitely helped out in my preparation for the exam. I also used my hands-on experience and knowledge with various NAS/SAN equipment - EMC VNX storage arrays.

Good luck to those studying for the exam!! If I can help with any questions let me know.
