I think I can get an understanding of the bits covered from the QA website

http://qa.com/training-courses/technical-it-training/microsoft/microsoft-sql-server/microsoft-sql-server-2008-and-r2/designing,-optimizing,-and-maintaining-a-database-administrative-solution-for-microsoft-sql-server-2008/

Couldn't find 50400 on the MS learning website any more, guess its due to the exams being retired soon so the course is obsolete.
