I’m currently studying for the Microsoft 74-409 exam: Server Virtualization with Windows Server Hyper-V and System Center, and have put together a list of resources which would be useful for anyone studying for the exam or interested in Hyper-V and System Center Virtual Machine Manager.
Microsoft are currently running a promotion at the moment and offering the exam free of charge (usually £99.00) if taken before 30th June 2014. See the link here for more details.
