This a great weeder question. Asking questions like this are often signs that: (A) The interviewer doesn't know how to interview since they are wasting time asking questions that tell them very little about the candidate. (B) The interviewer might be the type of interviewer who likes "trick" questions which can be a sign of someone who more interested in proving that they know something the interviewee doesn't. Remember, the candidate is interviewing you/your company.
