What are Kafka's port conventions?

Standard Kafka ports: 9092 — default broker plaintext listener (PLAINTEXT). 9093 — SSL/TLS listener (SSL). 9094 — SASL_PLAINTEXT listener. 9095 — SASL_SSL listener. 9999 — JMX monitoring. For KRaft: 9093 is also used for the controller quorum listener. These are conventions, not requirements — ports are fully configurable via the listeners and advertised.listeners broker configurations.

Expected key concepts: 9092, 9093, 9094, 9095, 9999, JMX, plaintext, SSL, SASL, controller quorum, listeners, advertised.listeners
