Explanation

All four options are correct statements about Kafka in the Fusioninsight product. Option A is correct because Kafka requires each replica to reside on a distinct broker, so requesting more replicas than available brokers is physically impossible and will fail at topic creation. Option B is correct in that a Kafka Producer can influence message routing by specifying a partition key or target partition, which - combined with consumer group partition assignments - effectively determines which consumer instance processes the message. Option C is correct because traditional Kafka (as used in Fusioninsight) relies on Zookeeper to store and manage critical metadata including broker registrations, topic configurations, partition leadership, and consumer group offsets. Option D is correct in the Fusioninsight context, where sensitive data storage directories are locked in at installation time as a security measure and cannot be reconfigured afterward.

Since there are no distractors (all options are correct), the key exam trap here is assuming one or more statements are false - particularly D, which sounds restrictive, or B, which may seem to contradict Kafka's topic-based pub/sub model.

Memory tip: Think of the acronym RZPL - Replicas ≤ Brokers, Zookeeper holds metadata, Partition routing lets producers influence consumers, Locked sensitive directory post-install - all four are core Fusioninsight-Kafka truths.
