Kafka 代理会通知组协调器，一个消费者正在离开，组协调器会立即触发重平衡。 2. 消费者应用程序将少一个消费者来消费消息。 3. 消费者会通知组协调器它正在离开，组协调器会立即触发重平衡。 4. 消费者应用程序会因 NOT_ENOUGH_CONSUMERS 异常而崩溃。 **正确答案解析：** 消费者通过向指定为组协调器的 Kafka 代理发送心跳来维持其在消费者组中的成员资格以及对分配给它的分区的拥有权。只要消费者定期发送心跳，它就被认为是活跃的。当一个消费者干净地关闭时，它会通知组协调器它正在离开，这会触发一个重平衡，从而调整消费者对分区的分配。 **学习目标：** 通过本课程的实践考试，您将能够： * 熟悉 Confluent Certified Developer for Apache Kafka 考试的题型和难度。 * 检验您在 Kafka 各个核心领域的知识掌握程度。 * 巩固和深化对 Kafka 消费者组、重平衡等关键概念的理解。 * 提升考试信心，顺利通过认证。 **总结:** 本课程是您在 Confluent 认证 Apache Kafka 开发者考试前的“最后一站”，为您提供信心，帮助您顺利通过考试。课程内容丰富，解析详尽，是备考的理想选择。

Scroll below for the answerCorrect: 3.The way consumers maintain membership in a consumer group and ownership of the partitions assigned to them is by sending heartbeats to a Kafka broker designated as the group coordinator (this broker can be different for different consumer groups). As long as the consumer is sending heartbeats at regular intervals, it is assumed to be alive, well, and processing messages from its partitions. Heartbeats are sent when the consumer polls (i. e., retrieves records) and when it commits records it has consumed.When closing a consumer cleanly, the consumer will notify the group coordinator that it is leaving, and the group coordinator will trigger a rebalance immediately, reducing the gap in processing.=The questions are as per the Confluent exam syllabus of the official documentationRetake Endlessly - You can retake the exams as many times as you want100% Exam Coverage - Tests are updated regularly to keep them up to date with the current syllabusDetailed Explanations - You get detailed explanations for all the answers with reference links and official documentationMimic Real Exam - 60 multiple-choice questions, duration is 90 minutes and passing grade is around 70%Mobile-Compatible - All practice tests are compatible with the Udemy App30-Day Money-Back Guarantee - Get your money back if you're not satisfiedWe hope that by now you're convinced!
