Hi
Unlucky with the result. i too failed by only a few marks on monday this week and studied very much the same things as you. I even blogged about my experience of the exam and what I am now doing to hopefully pass it when i retake the exam.

It really is a tough exam and for me I battled as I felt i didn't know the VMware recommended way of doing certain things and I think i can learn these by doing some mock designs and doing the labs for them design workshop and then looking at the completed designs of the two scenarios and seeing what VMware felt was the correct way of doing it.
Good luck and you're definitley not alone in failing
