A. Configure multiple brokers.
B. Configure multiple listeners on the broker.

D. Configure LoadBalancer.
Explanation:
Kafka supports multiple listeners, each with its own port, hostname, and security protocol. This allows you to:
● Use one listener for internal communication (e.g., brokers, ZooKeeper, Connect, etc.) with one type of authentication (e.g., PLAINTEXT or SASL).
● Use a separate listener for external clients (e.g., producers and consumers) with a different protocol (e.g., SSL or SASL_SSL).
