Lync Server Technical Specialist Exam

Microsoft Lync Server 2010, Configuring exam is 70-664. 

There is no official preparation material available but Enrique Lima over at Geekswithblogs has pulled together an unofficial prep guide based on the exam objectives. I'll be attempting the exam in the next couple of weeks, once I get Designing and Deploying Messaging Solutions with Exchange out of the way. I'll update the post once I get into the study and attempt the exam.
