I'll clarify: I think the ability of people to respond adequately to these questions depends as much on their confidence as their knowledge, and that interpreting their answers is very subjective. In general, asking your suggested questions are a good way to make someone look dumb or fluster them, but not the best way to correctly identify their expertise. Only in limited contexts are questions like these asked in good faith.

They're still valuable to think about because if you're ever in a position to receive these sorts of questions, you should be prepared to give at least a couple types of concise and competent-sounding answers, whether the question is asked in good faith or not.
