This artifact contains classes and APIs required for stream processing like KStream, KTable, joins, aggregations, windowing, and state stores. While kafka-clients only supports producer and consumer functionality, kafka-core and kafka-server are bundled within the broker and not exposed as independent dependencies for client-side stream processing.Knowledge Area: Kafka ConnectQ: An administrator enables SASL_SSL but forgets to reconfigure clients. What happens when PLAINTEXT is closed?Producers switch to idempotent write modeClients auto-upgrade to SASL_SSLBrokers fall back to PLAINTEXT internallyClients fail authentication and cannot connectCorrect Answer: Clients fail authentication and cannot connectExplanation:When SASL_SSL is enabled on brokers, clients must also be reconfigured with the correct security protocol, authentication mechanism, and credentials. If the administrator disables PLAINTEXT without updating client configurations, the clients will continue attempting to connect using the unsecured protocol and will be rejected. Kafka does not automatically upgrade client connections to SASL_SSL, nor do brokers silently fall back. This results in failed authentication and connection errors until client configurations are corrected.Knowledge Area: Kafka Security (SASL/SSL Configuration)Q: If a company wants to transform input events from topic A into enriched data for topic B, which API should be chosen?Streams APIConnect APIAdmin APIProducer APICorrect Answer: Streams APIExplanation:The Kafka Streams API is specifically designed for real-time stream processing and transformation between Kafka topics. It allows developers to consume from topic A, apply transformations, aggregations, or enrichments, and then produce results to topic B. Connect API is used for integrating Kafka with external systems, Admin API manages cluster operations, and Producer API only publishes raw events without transformation logic.Knowledge Area: Kafka Streams
