A way better response is to give them the answer, and what you googled to get the answer.

So, like, when an intern tells me "This ticket says it doesn't work with nmcli and I don't know what that is. What should I do?" I go "Huh.... ok, so I googled nmcli and it turns out it's a command-line network manager tool. Have you tried running it from the command line?"

That way, you convey the information that they should google that kind of thing in the future, but don't imply that they're stupid for not knowing it automatically, and you still give them the opportunity to talk through it with you.
