Kidding. Don’t listen to the parent. The only problem with this question is that it’s general purpose and very well understood, but those aren’t issues. You should still ask people what port HTTPS uses even if it seems stupid because you’re going into an interview blind and you need to assess the experience of a person very quickly (and, sometimes you get surprised by charismatic fools). All questions are tools, this one will tell you that either the person knows this question very well from studying it (which is valid, and you would be able to tell) or they have some experience with it (more valid) but it will tell you where they are most comfortable talking about and you can dig more into various parts if you want.
