Setting auto.offset.reset=latest causes the consumer to read from?

• A. Beginning of the log
• B. End of the log
• C. Last committed offset
• D. The next offset after the consumer starts

Answer: (B)

Setting auto.offset.reset tells the consumer where to start when there’s no committed offset (or when the offset is out of range). With latest, the consumer positions itself at the end of each partition, so it begins consuming from the current end of the log. That means it will skip any existing messages and only read new messages that arrive after the consumer starts. If there’s already a committed offset for the group, the consumer will resume from that offset and auto.offset.reset won’t apply in that case. So the best description is that it reads from the end of the log.
