What about the pace of change in the certification world? What if you have earned a certification on say SQL 2005? When should you renew that, if at all? With every new release? 2 releases into the future? I know that there are technology changes between versions, but is one certification and real-world experience enough to demonstrate competency?

A lot of questions...I know. Answer whichever you feel like! 🙂

Thanks...Chris
