AThe <code>--bootstrap-server</code> option specifying the Kafka server address.

DThe <code>--max-messages</code> option to limit output.
Step-by-Step Solution

    The producer needs to know which Kafka server to connect to, specified by --bootstrap-server.

    Producer needs --bootstrap-server to connect [OK]
Quick Trick: Always include --bootstrap-server to avoid connection errors [OK]
