Building off of the Microsoft Certified Masters (MCM): Directory training and certification, this new certification includes 11 days of training, two written exams and one 8-hour certification lab exam. Slight tweaks to the program format reflect a decision to focus on core directory services, based on MCM feedback. Greater emphasis on targeted pre-reading and prerequisites to maximize classroom maximize classroom learning around core Active Directory functionality and design concepts, as well as PKI, Lightweight Directory Services, Group Policy and DFS.
For IT pros who have earned their MCM on Windows Server 2008 Active Directory the upgrade path is quite simple. You will only be required to take the two written exams that are current for the Windows Server 2008 R2 Directory program. Existing MCMs in Directory can re-sit an entire rotation and see significant savings in comparison to a full MCM course and includes all exams.
Microsoft Learning is offering a $1,000 discount for the MCM: Windows Server 2008 R2 program until January 1, 2010. More information is available here.
