Which port is used by the Schema Registry by default?

• A. 8082
• B. 9092
• C. 8081
• D. 8088

Answer: (C)

Schema Registry runs as its own HTTP service with a REST API, separate from the Kafka brokers. The port it listens on for that API is 8081 by default, so you access schemas through endpoints like http://localhost:8081/subjects. The other ports belong to different components: 9092 is the Kafka broker’s port, 8082 is commonly used by the REST Proxy, and 8088 is not the Schema Registry’s default. So the port used by the Schema Registry by default is 8081.
