How do you respond when you do not know the answer to a question?
Nobody's perfect and nobody knows the answer to every question. Of course, tell the recruiter that you'd do your best to master info relevant to your role, but for the instances that you're not ready with an answer, you'd take responsibility. Also, you will seek out the correct information for the customer but you may have to consult with management or a technical specialist.
"I believe that honesty would be the best answer. I'd sincerely apologize and then reassure the customer that I'll be transferring them to someone who can provide an answer to their query. Or if company policy dictates, I will personally call a specialist and talk with them myself to get the answer for the customer."

Honestly, if I do not know the answer I will advise my customer truthfully and then research to see if I can find the answer. If I am unable to assist or get assistance in order to help the customer I would transfer them to someone who can.

This is a great response. Everyone should appreciate an honest response. Consider sharing how you would assure the customer that you are working on obtaining an answer and when they can expect to hear back from you or someone else with the ability to help if there isn't someone immediately available to answer their question.
