Question 1 Domain 1 Apache Kafka® Fundamentals

The REST Proxy requires to receive data over REST that is already base64 encoded, hence it is the responsibility of the producer

Question 4 Domain 2 Apache Kafka® Application Development
A client connects to a broker in the cluster and sends a fetch request for a partition in a topic. It gets an exception Not Leader For Partition Exception in the response. How does client handle this situation?
In case the consumer has the wrong leader of a partition, it will issue a metadata request. The Metadata request can be handled by any node, so clients know afterwards which broker are the designated leader for the topic partitions. Produce and consume requests can only be sent to the node hosting partition leader.
Question 5 Domain 1 Apache Kafka® Fundamentals
There are 3 brokers in the cluster. You want to create a topic with a single partition that is resilient to one broker failure and one broker maintenance. What is the replication factor will you specify while creating the topic?
1 is not possible as it doesn't provide resilience to failure, 2 is not enough as if we take a broker down for maintenance, we cannot tolerate a broker failure, and 6 is impossible as we only have 3 brokers (RF cannot be greater than the number of brokers). Here the correct answer is 3
Question 6 Domain 2 Apache Kafka® Application Development
If a topic has a replication factor of 3...
Replicas are spread across available brokers, and each replica = one broker. RF 3 = 3 brokers
Question 7 Domain 1 Apache Kafka® Fundamentals
How will you read all the messages from a topic in your KSQL query?
Consumers can set auto.offset.reset property to earliest to start consuming from beginning. For KSQL, SET 'auto.offset.reset'='earliest';
