Huawei HCIP-Big Data Developer V1.0 Sample Questions:
In the Fusioninsight HD product, what is wrong about the Kafka secure and non-secure port description?
(Note: The old API refers to the old Producer API and the old Consumer API. Among them, the old Consumer API: refers to the interface defined in kafka.consumer.ConsumerConnector; the old Producer API: refers to the interface defined in kafka.producer.Producer.)
- A. The premise for the old API to access a topic through port 21005 is that the server parameter allow.everyone.if.no.acl.found is set to true, and the topic does not have ACL attributes set
- B. The old API only supports access to port 21005; the new API is compatible with access to non-secure port 21005 and secure port 21007.
- C. For topics with ACL set, you can use the old API to connect to port 21005 for access.
- D. Kafka cluster security access port defaults to 21007, non-secure access port defaults to 21005.
