What are the recommended resources for preparation to get CCA and CCEA? Has anything good come out yet for the 4.5 tests? Citrix's website lists the certifications under Presentation Server 4 but there are separate tests for 4.0 and 4.5. Does anyone know if the actual certification paperwork will indicate if it's 4.0 or 4.5, or it will just say "Presentation Server 4"
