I've just discovered when the beta and final VCP on vSphere 4 exams will be available.
The beta exam for vSphere 4 will be available June 29th, 2009. Candidates eligible for the beta exam will automatically be contacted by VMware. These candidates must be VCP3 certified and beta product users.
The final release of the VCP on vSphere 4 exam will be available publicly on August 1st, 2009.
Sorry for the lack of updates over the last couple of weeks, I've been to Spain on holiday!
