On January 22, VMware released a new version of the VCP5-DCV Exam, which covers vSphere 5.5. The new exam code is VCP550.
If you are already a VCP5-DCV, then you do Not need to take this exam. If you are not a VCP5-DCV, then you have two choices for the exam requirement. You can take either the VCP550 exam on vSphere 5.5 or the VCP510 exam on vSphere 5.0/5.1. In either case, the certification is VCP5-DVC.
