Explanation: One of the benefits of using Apache Kafka for real-time data streaming is its fault-tolerance and high availability. Kafka is designed to provide durability, fault tolerance, and high availability of data streams. It can handle large volumes of data and offers high scalability and throughput. Kafka also allows for centralized message storage and processing, enabling real-time processing of data from multiple sources.

(Amazon Web Services) or Azure. Kafka can also be containerized using technologies like Docker and deployed in container orchestration platforms like Kubernetes. However, deploying Kafka on mobile platforms like Android or iOS is not a typical use case. Kafka is designed for server-side data processing and messaging, and it is not optimized for mobile devices.
Which of the following is a feature of Kafka Streams?
It provides a distributed messaging system for real-time data processing.
enables automatic scaling of Kafka clusters based on load. wer: B
anation: Kafka Streams supports exactly-once processing semantics f m processing. This means that when processing data streams using Ka ms, each record is processed exactly once, ensuring data integrity and istency. This is achieved through a combination of Kafka's transaction aging and state management features in Kafka Streams.

To specify the topic to consume messages from.
To determine the behavior when there is no initial offset in Kafka or if the current offset does not exist.
To configure the maximum amount of time the consumer will wait for new messages.
Answer: C
Explanation: The auto.offset.reset property is used to determine the behavior when there is no initial offset in Kafka or if the current offset does not exist. It specifies whether the consumer should automatically reset the offset to the earliest or latest available offset in such cases.

Which of the following is NOT a core component of Apache Kafka?

Kafka Connect ework for connecting Kafka with external systems. Kafka Streams is ry for building stream processing applications with Kafka. However, ka Manager" is not a core component of Kafka. It is a third-party tool anaging and monitoring Kafka clusters.

Kafka replication allows data to be synchronized between Kafka and external systems.
Kafka replication enables compression and encryption of messages in Kafka.
Answer: A
Explanation: Kafka replication ensures fault tolerance by storing multiple
copies of each message in a topic across different Kafka brokers. Each topic partition can have multiple replicas, and Kafka automatically handles replication and leader election to ensure high availability and durability of data.
is Kafka log compaction?
process that compresses the Kafka log files to save disk space. process that removes duplicate messages from Kafka topics.
process that deletes old messages from Kafka topics to free up disk s process that retains only the latest value for each key in a Kafka topic
wer: D
anation: Kafka log compaction is a process that retains only the latest ach key in a Kafka topic. It ensures that the log maintains a compact sentation of the data, removingany duplicate or obsolete messages. L paction is useful when the retention of the full message history is not red, and only the latest state for each key is needed.

What is the significance of the acks configuration parameter in the Kafka producer?
It determines the number of acknowledgments the leader broker must receive before considering a message as committed.
It defines the number of replicas that must acknowledge the message before
considering it as committed.
It specifies the number of retries the producer will attempt in case of failures before giving up.
It sets the maximum size of messages that the producer can send to the broker.
anation: The acks configuration parameter in the Kafka producer mines the number of acknowledgments the leader broker must receiv re considering a message as committed. It can be set to "all" (which m
sync replicas must acknowledge), "1" (which means only the leader owledge), or a specific number of acknowledgments.

This command creates a new consumer group with th fied group name. The "--bootstrap-server" option specifies the Kafka strap server, and the "--group" option specifies the consumer group na ther options mentioned either have incorrect parameters or do not in ecessary bootstrap server information.
