To create topics To mirror messages between Kafka clusters To compress messages To manage consumer offsetsHow does Kafka handle message retrieval for consumers? By using ZooKeeper By allowing consumers to fetch messages from a specific offset By compressing messages By using SSL/TLSIn Apache Kafka, what is the purpose of the offset commit strategy \\\"earliest\\\"?To start consuming from the earliest available offset when no committed offset is foundTo always consume from the beginning of the topicTo commit offsets as early as possibleTo consume only the most recent messagesWhat is the purpose of the num.network.threads configuration in Kafka?To set the number of threads for network requestsTo set the number of I/O threadsTo set the number of background threadsTo set the number of producer threadsWhich Kafka configuration parameter is used to set the number of acknowledgments the producer requires? acks num.acks producer.acks acknowledge.setWhich Kafka API is used for administrative tasks like creating topics? Admin API Management API Cluster API Config APIWhat is the difference between Apache Kafka and Amazon Kinesis?Kafka is open-source, Kinesis is proprietaryKafka doesn\\\'t support streamingKinesis is open-sourceKafka is proprietaryWhat is the difference between Apache Kafka and Amazon Kinesis? Kafka is managed; Kinesis is open-source Kafka is open-source; Kinesis is managed No difference Both are managed servicesHow does Kafka handle consumer offsets? By storing offsets in ZooKeeper By storing offsets in Kafka itself By compressing offsets By using SSL/TLSWhat is the purpose of setting the fetch.min.bytes configuration in Kafka consumer?To reduce the number of fetch requestsTo increase message throughputTo decrease consumer lagTo improve data consistencyWhat is a benefit of Kafka\\\'s log-based architecture?Enables both real-time and batch consumersReduces storage requirementsIncreases message throughputImproves network efficiencyWhat is the purpose of the min.insync.replicas configuration in Kafka?To set the minimum number of replicas that must acknowledge a writeTo set the minimum number of replicas for a topicTo set the minimum number of in-sync replicas for a partitionTo set the minimum number of brokers in the clusterWhich Kafka API is used for modifying broker and topic configurations?Admin APIConfig APICluster APIManagement APIHow does Kafka ensure message delivery in case of network failures?Through retries and acknowledgementsIt doesn\\\'t, messages may be lostBy storing all messages indefinitelyBy using ZooKeeper as backupHow does Kafka handle data stream transformations with custom transformers?Using Kafka Streams APIAutomatically in brokersOnly in producersNot supportedWhat is the purpose of the replica.fetch.max.bytes configuration in Kafka?To set the maximum bytes for a fetch request from followersTo set the maximum replica sizeTo set the maximum partition sizeTo set the maximum message size Score: 0/25 Retake Quiz Next Set of Questions
