You are managing a high-throughput Kafka cluster with multiple brokers running in a Cloudera Data Platform (CDP) environment. Your team has recently implemented a new security policy requiring strong authentication for all producers and consumers. However, you notice that some consumers are experiencing intermittent connection failures. After investigating, you determine that the issue is related to the authentication handshake timing out before the consumer can successfully authenticate. Which of the following strategies can you implement to address this issue?
You're running a Kafka cluster with several topics used for real-time data ingestion and processing. To ensure data integrity and prevent data loss, you've configured the `replication.factor` property to 3 for all topics. However, you've recently encountered a scenario where a broker node crashed, resulting in data loss on a specific topic. Upon investigation, you find that the topic had only two replicas available at the time of the crash. What could be the reason for this data loss, despite the `replication.factor` being set to 3?
You're configuring a new Kafka cluster in CDP to handle real-time event streaming for an application with strict latency requirements. You need to ensure that the cluster can scale horizontally to handle increasing message volumes. Which of the following configurations would be most suitable for achieving high scalability and low latency?
Your Kafka cluster is experiencing high message backlog on a specific topic. While investigating the issue, you discover that the consumer group responsible for processing the topic's messages is lagging significantly behind. The consumer group has 10 consumers, but only one of them is actively processing messages. The other 9 consumers are not consuming data and appear to be idle. What could be the potential reason for this behavior and how would you resolve it?
You're managing a large Kafka cluster with many producers and consumers. To ensure secure communication between these components, you've implemented SSL/TLS encryption for all network connections. However, you're noticing a significant performance degradation in your cluster's throughput. What could be contributing to the performance drop after enabling SSL/TLS encryption?
