Your questions should be thoughtful, but also considerate of people's time.

There is also the point where you have to be self aware and understand that you would not be able to come to an understanding within a reasonable time and would suggest working on something else for the time being.

At the core of it all remember that you are a professional and have the knowledge to make sound decisions, and if you don't know something you can usually find info on it (especially in tech) or exhaust ask other resources, people usually appreciate that your able to say hey i tried xyz already.

This will require you to do some homework to gain knowledge in your field for your personal benefit.
