VCP exams are scored by the PearsonVUE testing software at the time of completion - it's their systems that tell VMware you've passed, but the VCAP-DCA exams are scored by a person at VMware and nobody from PearsonVUE is involved in that process - that's exactly my point.
All my certifications are on my VMware transcript on vmware.com, but my VCAP-DCA only shows as "taken" on my exam history on pearsonvue.com.
You will get an email from VMware with your VCAP-DCA result once it's been scored by them.
