This question may look similar to one you were asked earlier in the interview. Interviewers will often ask the same questions at different times during the interview or in different ways. The reason behind this is to confirm your answer to the previous question and to make sure you are being consistent throughout the interview. Consistency throughout the interview indicates you are answering your questions genuinely and truthfully and are not fabricating the answers.

Keeping your answers to questions brief and to the point will help you remain consistent throughout the interview. Interviewers will always ask a follow-up question if they want you to expand on your answer. Doing this also helps keep the interview on track and enables the interviewer to move on to their next question if they do not need any additional information.

"No, it is not possible for two CAN nodes to send the same identifier at the same time. The CAN system's arbitration function prevents this. If allowed to happen, one of the transmitting nodes will detect that its message has been distorted outside the arbitration field. This is prevented by the error handling of the CAN which will turn off the bus for one of the transmitting nodes, known as the bus-off mode."
