Intelligent Apache Kafka Test Quiz

Kafka can be referred to as a publish-subscribe messaging system. Kafka is a distributed streaming platform that allows multiple producers to write data to multiple consumers in a publish-subscribe fashion. It provides a scalable and fault-tolerant architecture for real-time data streaming, making it suitable for use cases such as event sourcing, data pipelines, and real-time analytics. Kafka's publish-subscribe model allows messages to be broadcasted to multiple subscribers, enabling efficient and decoupled communication between different components of a system.

Apache Kafka's architecture relies on three core components: producers, consumers, and brokers. Producers publish messages to Kafka topics, which are categories for storing messages. Consumers subscribe to topics and process messages. Brokers are servers that host topics and manage message storage and delivery. Reducers are not part of Kafka's architecture; they are a concept in distributed computing frameworks like Hadoop.

Linkedln is the correct answer because it was the organization that originally developed Kafka. Kafka was created by a team of engineers at Linkedln to handle their real-time data processing needs. It is a distributed streaming platform that is widely used for building real-time data pipelines and streaming applications.

Kafka is written in Scala. Scala is a programming language that runs on the Java Virtual Machine (JVM) and is known for its concise syntax and strong support for functional programming. Kafka, which is a distributed streaming platform, was initially developed at LinkedIn and later open-sourced. The choice of Scala as the language for Kafka's implementation was influenced by its compatibility with the JVM and its ability to handle the high-performance requirements of real-time data streaming.

In Kafka, a broker refers to a server. A Kafka cluster consists of multiple brokers, each acting as a server that stores and manages the Kafka topics, partitions, and messages. The brokers are responsible for handling the publish and subscribe requests from clients, as well as replicating and distributing the data across the cluster. Therefore, the correct answer is Server.

Queuing is a method used in traditional message transfer. It involves storing messages in a queue and processing them in the order they were received. This method ensures that messages are delivered reliably and in the correct sequence. Apache Kafka, Zookeeper, and Cluster are not specifically related to queuing, but rather serve different purposes in distributed systems.

Zookeeper is used to communicate between two nodes. Zookeeper is a centralized service that helps in maintaining configuration information, naming, providing distributed synchronization, and providing group services. It acts as a coordination service for distributed systems, allowing nodes to communicate and synchronize with each other. Therefore, Zookeeper is the correct answer for this question.

Kafka provides two traditional methods of message transfer. These methods include the producer-consumer model and the publish-subscribe model. In the producer-consumer model, messages are sent from a producer to one or more consumers. In the publish-subscribe model, messages are published to topics and then consumed by one or more subscribers. These two methods allow for flexible and scalable message transfer within Kafka.

The maximum message size a Kafka server can receive is 1,000,000 bytes.
