What is the purpose of Kafka\\\'s __transaction_state topic?To manage transactional guaranteesTo store actual messagesTo handle authenticationTo create new topicsHow does Kafka handle delivery timeouts? By using ZooKeeper By using the delivery.timeout.ms configuration parameter By compressing messages By using SSL/TLSWhich of the following is true about the \"enable.auto.commit\" configuration property in Kafka?When set to true, offsets are committed automaticallyIt controls the message compression algorithmIt sets the maximum message sizeIt defines the number of partitionsWhat is the difference between \\\"at least once\\\" and \\\"exactly once\\\" semantics in Kafka consumers?At-least-once may deliver duplicates, exactly-once guarantees no duplicatesAt-least-once guarantees order, exactly-once doesn\\\'tAt-least-once is faster, exactly-once is slowerAt-least-once uses less memory, exactly-once uses moreHow does Kafka ensure fault tolerance?Through data replicationBy using a single serverWith manual backupsBy avoiding partitionsWhich Kafka tool is used for monitoring and alerting?Kafka ManagerKafka MonitorKafka Cruise ControlConfluent Control CenterWhat is the purpose of the batch.size configuration property in Kafka producer?Control the number of messages sent in a single requestSet the maximum message sizeDefine the number of partitionsSet the replication factorWhat is the primary function of a Kafka broker?To produce messagesTo consume messagesTo store and manage partitionsTo coordinate the clusterWhat are the key differences between Spring AMQP and Spring Pub-Sub? Spring AMQP is for point-to-point; Spring Pub-Sub is for publish-subscribe No differences Both are for publish-subscribe Both are for point-to-pointWhat is the Kafka buffer time typically used for?To batch messages for efficiencyTo delay message deliveryTo sort messagesTo compress messagesWhat is the role of a Kafka Streams state store changelog topic compaction?To reduce the size of state store backupsTo encrypt state dataTo improve read performanceTo handle authenticationHow can you implement a graceful shutdown in a Kafka consumer using Java?Call consumer.wakeup() and handle WakeupExceptionUse System.exit(0)Close the consumer without any preparationIncrease the session timeoutHow can you monitor the performance of a Kafka cluster?Using JMX metricsOnly through log filesBy manually checking each brokerPerformance monitoring is not possibleWhat is the purpose of Kafka Connect?To integrate Kafka with other systemsTo connect multiple Kafka clustersTo manage network connectionsTo create new topicsWhich Kafka feature allows for processing streams of data with fault-tolerance? Kafka Streams Kafka Connect Kafka REST Proxy Kafka Mirror MakerWhat is the role of the Kafka consumer\\\'s position() method? To consume messages To produce messages To get the current offset for a partition To manage brokersWhat is the purpose of the unclean.leader.election.enable configuration in Kafka? To allow out-of-sync replicas to become leader To enable leader election To allow multiple leaders To enable automatic leader balancingWhich of the following is NOT a recommended approach for reducing Kafka consumer lag?Decreasing the number of consumersIncreasing partition countOptimizing consumer codeIncreasing consumer parallelismHow can you encrypt data at rest in Kafka?Using filesystem-level encryptionKafka doesn\\\'t support encryption at restOnly through SSLBy encrypting individual messagesWhat is the role of the controller in a Kafka cluster? To manage topics To manage brokers To manage partition leadership To handle message compressionWhat is the main difference between Kafka and Apache Gearpump?Kafka is a messaging system, Gearpump is a processing frameworkKafka is newerGearpump doesn\\\'t support streamingKafka doesn\\\'t support real-time processingHow does Kafka handle message ordering within a partition?
