Dont feel bad, If anything I've learned is that the database industry is differenct in most area and testing doe'nt mean a thing. I've been a dba since 92 with both oracle and sql server as a consultant. I solve problem and and I did'nt see any plane dropping out the sky in the US during the late 90s.(Federal Aviation Administration(Air Traffice Services Administrator)). Check the web, its a number of practice test you can use before taking it again.
Well, it took me about 3 months to from start until exam. I work as developer and dba so I had a basic knowledge of SQL Server. I used a book from the dummies series (don't know if it still exists) and the Books Online to find the stuff that I didn't know and I bought the Selftest exam for 70-228 and that's all.
I chose the 70-215 and I'm almost ready studying. This took me some more time to get to know, because I'm not the network admin so there were some more holes in my knowledge. The main reason for choosing this one, is that our company does not use Windows 2003 Server yet, so it seemed logical to study for something you can practise. Furthermore, I found the parts about monitoring performance quite straight forward as it is also a part of the 228 exam.
Passing your first exam makes you a microsoft certified professional (mcp). There are some priviliges to that, but that's all. And by the way, the 70-019 exam is scheduled to be discontinued after june 30.
no, don't take it all. Why choose a SQL 7 exam for your SQL 2K certification and knowing SQL 2K5 is (supposed to be) on it's way. I'll take one of the .net exams to prepare for the new features in SQK 2005.
