How about
How would you use a desktop database as the backend for a multi user enterprise system?
Or the user says their printer is not working. Come up with a set of fault finding steps and explin the why of each one.
Or for DBAs. Given you have only one database and you need to collect and report to it. How would you decide where and when to optimise it, and why.
Course you need someone on the other side of the table, who understands the answers....
So may be feeding 5000 with one loaf and a small fish would be an alternative.
