I've been holding off for some time now waiting for a Sharepoint MCP exam thats more to do with my job role around architecture and design. Sadly I dont think Microsoft will ever structure an exam like this for Sharepoint so under increasing pressure from my company to get MCP'd, I dived into the Configuring WSS 3.0 (exam 70-631).
It came across very easy if you have a background rolling out Sharepoint before although the weighting of questions relating to infrastructure like Network Load Balancing was a little high and something I had to school up on.
I think thats about all I can say about the exam but anyone wanting to get MCP'd around Sharepoint - this is your ticket. I was done in 15 minutes with a 100% score.
Hopefully the MOSS exam (70-630) is better.
