Which Kafka Streams feature allows for joining data from multiple topics based on a common key?
Branching
MapReduce
Stream-Table Join
Windowed Aggregation
In Kafka Streams, what is the primary difference between stateful and stateless processing?
Stateless processing is faster than stateful processing because it does not require data storage.
Stateful processing is used for filtering data, while stateless processing is used for transformations.
Stateful processing allows access to historical data, while stateless processing only considers the current record.
Stateful processing is more scalable than stateless processing.
What is the primary purpose of monitoring Kafka metrics?
To identify and troubleshoot security vulnerabilities in Kafka
To understand and optimize Kafka cluster performance and health
To track the number of messages consumed by each consumer group
To debug application code that interacts with Kafka
What tool is commonly used to manage and monitor Kafka Connect connectors?
Kafka Control Center.
Kafka Connect REST API.
ZooKeeper CLI.
Kafka Streams API.
What is the primary function of Kafka Streams?
Storing and persisting streaming data
Guaranteeing exactly-once message delivery
Performing real-time data analysis and transformations on streams
Managing cluster resources for Kafka brokers
What is the primary purpose of Kafka Connect within the Kafka ecosystem?
Providing a scalable and distributed messaging platform.
Real-time stream processing of data within Kafka topics.
Simplifying the integration of data between Kafka and external systems.
Managing and monitoring the health of Kafka clusters.
What is a key difference between synchronous and asynchronous producers in Kafka?
Synchronous producers block until the broker acknowledges message receipt, while asynchronous producers send messages without waiting for confirmation.
Synchronous producers use a push-based model, while asynchronous producers use a pull-based model.
Synchronous producers are only used for high-throughput scenarios, while asynchronous producers are suitable for low-throughput cases.
Synchronous producers send messages to multiple topics, while asynchronous producers send to a single topic.
Which of the following is NOT a core concept in stream processing?
Aggregation
Batch processing
Joining streams
Windowing
How does Kafka ensure data durability and availability in the event of a broker failure?
By replicating partitions across multiple brokers.
All of the above.
By using a distributed commit log for tracking message offsets.
By writing all messages to a persistent disk before acknowledging them.
What is the role of a Kafka Controller in a cluster?
Handling data replication between brokers
Performing load balancing of messages
Monitoring and managing the health of brokers
Managing message consumption rates
