Deploying Apache Kafka in production and testing environments requires a solid understanding of performance tuning, monitoring, reliability, and fault tolerance. This section includes multiple choice questions (MCQs) focused on Kafka’s operational aspects, such as production readiness, testing strategies, performance benchmarks, log retention, durability, and monitoring tools.
These MCQs are designed to help engineers prepare for real-world interviews, Kafka certifications, and practical deployment scenarios with confidence.
1.) What is the recommended replication factor for critical Kafka topics in production?
2.) Which tool is commonly used to monitor Kafka performance?
3.) Kafka ensures message durability using:
4.) Which Kafka parameter controls how long messages are retained?
5.) How can you reduce message loss in production Kafka clusters?
6.) What does ISR stand for in Kafka?
7.) What’s the purpose of Kafka’s min.insync.replicas config?
8.) Which testing strategy is best for validating Kafka-based applications?
9.) Which Kafka feature allows for infinite retention of the latest value per key?
10.) In a test environment, what tool is best to simulate Kafka producers and consumers?
