I'm glad you've found this conversation interesting; I have too 🙂 I tend to think these questions are like ones you get when you go for an interview for a DBA job or something, technically they're correct but their context in real life is lacking in the extreme and life is very rarely clear cut, unambiguous or pre-defined in its scope.

Even if you didn't read the question that clearly, are you really doing anything any one of us haven't done before? I can't remember the number of times i've misunderstood a specification or a request and come out with something completely wrong. I just take those lessons and move on hoping not to repeat them 🙂
