Over the past few months, I've been prepping for SQL Server 2012 Administration exam 70-462. I have experience performing admin tasks in the development and QA environment, and even a short stint as a production DBA many years back. Indexing, performance optimization, and role based security are just as much a part of what I do as a database developer as writing T-SQL. However, there was a lot of new material, things like installation options, change data capture and various disaster recovery features, that was new to me. It really helps to have something like a certification to use as a target for study and a good study guide that lays out the material in a comprehensive and structured way.

As a side, I was reading an article once that most medical operations (not brain or heart surgery but more routine out-patient procedures) could actually be performed by someone wihout only a few hundred hours training. Understand that they would only know the step-by-step technicals of performing that *one* specific procedure, and they would need a real medical doctor, anesthesiologist, and fully equipped facility on hand to back them up. This would basically be Henry Ford meets healthcare.
