Which port is the Kafka Broker listening on by default?

Explanation:
The port the Kafka broker listens on by default for client connections is 9092. This port is where clients (producers and consumers) connect using Kafka’s wire protocol. The number 2181 is the default port for Zookeeper, which older Kafka setups used for metadata management, not the broker’s client port. The other ports (like 8081 or 8082) are not the Kafka broker’s default port for the standard client protocol; they show up in various setups for different services or interfaces, but they’re not the default Kafka broker port. You can change the port by configuring the broker’s listeners (or advertised.listeners) in server.properties, but 9092 remains the default for normal client connections.
