Design exams are really difficult and require a lot of experience, not only in virtualization, but also in storage and networking and IT project management.
Blueprint could help, but is not enough.
Workshop design course could help for DCD.
I agree, Design Workshop could help, but you need experience. I attended it at last PEX, it answer many question on the "Why" side of design, but you need experience to be able to pass the exam. The scope of the exam is larger than VMware software issue, if you don't know storage and networking you will find it hard.
Design task are larger in scope than VCP-style exam. While I attended the Design Workshop, I was able to see who work the technology and understand it and other knowing only side of the equation... (sales, storage, networking...).
I have read Forbes Guthries book "vSphere Design", the first edition and now reading the second edition, they are really helpful.
Also attend the vSphere Design Workshop, it is a great course.
