I passed Red Hat's Exam 436 today, Certificate of Expertise in Clustering and Storage Management.  Now on to my RHCDS and hope to pass the Satellite exam next.

I highly recommend any one interested in learning more about Linux and any of Red Hat products to take their training classes and/or take their exams.
