Passed DCD on Saturday.
Now I have both VCAP test passed! woohoo
Test was pretty tough, I thought that it was more difficult that the DCA. At least the DCA had a blueprint lol
The DCD challenges your knowledge of the entire datacenter (networking & storage, power & cooling not so much haha)
Do yourself a favor and read Scott Lowe's design book and spend some time going through the DCD sample exam on the mylearn site.
Finished the exam with 4 minutes remaining.
