I followed pretty much the outline of what I set out on the battle plan to the letter, the design guide is a must read and the vBrownBag is time well spent.
Each of these resources approach assisting you with the exam in slightly different ways; the design guide tells you how NSX-T should be designed and the caveats around the few different supported architectures. Whereas the vBrownBag is focussed around the softer skills of a design, allowing you to think like an architect – finding risks, assumptions, constraints and requirements.
I think this was a very valuable exam and to be honest – I found it pretty enjoyable to study and undertake.
The next exam for me will be Cisco DevNet in a ramp up for next year – albeit, VMware VCAP-NV Deploy, I’ve got my eye on you!
