Back in December I took my first VCDX exam the Enterprise Exam and once I got the notice that I passed (took over a month for the results to come in) I scheduled my Design Exam which I took last week. Overall I passed both exams with more than enough points to qualify for the next stage. So here is the break down on what to study and how to study it.
