If you don't know the answer, then you may not be qualified to support this type of configuration. Always start with the documentation.
And if you are answering this level of interview question, saying "I don't know, but can learn" will be a lot better than getting in over your head. Because the follow-on questions will show whether or not you are trying to BS your way through the answer. And if they are any good at interviewing, you won't know that you failed until you don't hear back from them.
