If you're going to be doing tech support, it's probably something you should think about. As far as what is the answer, I would say one that shows some thought, uses some logic and is organized.
Hopefully, during the interview process, you've learned what is expected, so that may give some insight. What are the nature of problems? Are most of them solved quickly? Is there a procedure for escalating problems? Ask what your boss will prefer: solving a lot of little problems to make the reports look good or are you encouraged to take on difficult problems and use the time necessary to come up with an effective solution.
Often, support jobs require you to play a "game" so you better know how they're keeping score.
