I have passed my VCAP-DCD exam last week.
In addition to all other's posts, I would like to add the following and I hope it will help all those who are planing to take this exam:
1- Don't worry about the time too much if you are well prepared.
2- Never skip a question after spending time on it since you will end-up wasting time reading these questions again.
3- For all Non-MC (Multiple Choice) question, if you don't answer the question, it will not appear as incomplete in the review table. I think it's an exam bug. Make sure you revisit all the question so you don't miss any un-answered questions.
4- I highly recommend the VMware Design Workshop course.
5- I highly recommend reviewing the VMware: Configure and Install materials. In addition, VCP4 exam blueprints will really help.
Good luck for everyone!
