Funny thing was, I almost didn't get to do the exam because the Prometric testing site @ North Ryde (in Sydney) didn't have my name registered (and the name of 3 other guys who arrived at the testing centre). This was because I rescheduled the exam online (at http://www.register.prometric.com/Index.asp) the day Prometric closed over the holiday period. I had to wait around for an hour before the Prometric help desk opened up and did a data synchronisation. Why the process isn't just a scheduled SQL job is beyond me.
Without violating the Non-Disclosure Agreement (these are all in the preparation guide at http://www.microsoft.com/learning/en/us/exams/70-630.mspx), here are some of the things to look for:
- Content types, Content types, Content types
- Security, Audiences and how to enable/disable Personalisation functionality
- Business Data Catalogs
- Know all the stsadm command line parameters inside out - http://technet.microsoft.com/en-us/library/cc263384.aspx
- Know the innards of the logging and diagnostic functionality of MOSS.
My primary sources of information were the 1200 page corker named "The Microsoft Office SharePoint Server 2007 Administrator's Companion", SharePoint 2007 Central Administration online help and, of course, TechNet for SharePoint - see http://technet.microsoft.com/en-au/office/sharepointserver/default.aspx
