How did you qualify training-wise for your VCP5?
If you did Install Configure Manage 5 you don't qualify for VCP4 unless you take the What's New 4 training, there is literally one more online course scheduled on Feb 23/24: http://mylearn.vmware.com/portals/www/search/results.cfm?ui=www_edu&menu=search-results&searchtype=simple&category=schedule&id_subject=10069&deliveryType=16&filters=deliveryType
Gaining VCP4 is the only current way you can currently qualify to do a VCAP exam til the release of the VCAP5 exams. DCD5 is in beta and could be released in April, no news at all on DCA5.
