Most humble blue belt DBA Steve agrees as well. I really wish the exams would be redone becuase there is a HUGE potential for really testing people, proving knowledge, AND making $$. It'd be nice to have 8 levels of DBAs, and 3 or 4 specialties (DTS, ETL, warehousing, Analysis, MDX, etc.).
Oh well, maybe MS will wake up one day and do it.
Personally, I'm a self study guy. Training is too expensive, rather hit my boss up for PASS expenses . I think if you have enough experience, then you don't need that much study.
