If I don't know the answer to a question, I will probably just do what I pretty much did for the last question, which is just be honest. If you don't know the answer to a question, then pretend that you do, because you'll probably get something wrong. And especially when it comes to your official duties in a work environment, you don't want to give anyone incorrect advice or direction. If it's in a customer service situation, if a customer asks me a question I don't know the answer to, I'll, of course, apologize that I don't know the answer, even if it's perfectly sensible that I don't know. Sometimes we just don't have certain information that's accessible to us or certain education or training, but just be honest and just apologize any ways that you don't know the answer to the question, and then hopefully be able to point them to someone who should know the answer to the question. But whenever someone asks you any question you don't know the answer to, it's always best to just be honest and not try to fake it until you make it and make it up. You should probably know the answer to the question if you don't, unless it's a situation where it's justifiable that you don't, in which case I would just hope that the person asking the question would be understanding, and if they're not, that's kind of not my fault and I guess not my concern if there's something that's beyond my control and my ability and my knowledge and someone judges me for it. So just be honest and do the best that you can, of course, to know all the knowledge that you are obligated to know and that you should be learning, but when faced with a question that you don't know the answer to, certainly just be straight up.
