(You are implementing a Kafka Streams application to process financial transactions.
Each transaction must be processed exactly once to ensure accuracy.
The application reads from an input topic, performs computations, and writes results to an output topic.
During testing, you notice duplicate entries in the output topic, which violates the exactly-once processing requirement.
You need to ensure exactly-once semantics (EOS) for this Kafka Streams application.
Which step should you take?)

• A.Set processing.guarantee=exactly_once_v2 in the Kafka Streams configuration.
• B.Set enable.idempotence=true in the internal producer configuration of the Kafka Streams application.
• C.Set enable.exactly_once=true in the Kafka Streams configuration.
• D.Enable compaction on the output topic to handle duplicates.

Which two statements are correct about transactions in Kafka?
(Select two.)

• A.All messages from a failed transaction will be deleted from a Kafka topic.
• B.Consumers can consume both committed and uncommitted transactions.
• C.Transactions are only possible when writing messages to a topic with single partition.
• D.Information about producers and their transactions is stored in the _transaction_state topic.
• E.Transactions guarantee at least once delivery of messages.

What is accomplished by producing data to a topic with a message key?

• A.It provides a mechanism for encrypting messages at the partition level to ensure secure data transmission.
• B.Messages with the same key are routed to a deterministically selected partition, enabling order guarantees within that partition.
• C.Kafka brokers allow you to add more partitions to a given topic, without impacting the data flow for existing keys.
• D.Consumers can filter messages in real time based on the message key without processing unrelated messages.

You are working on a Kafka cluster with three nodes. You create a topic named orders with:
replication.factor = 3
min.insync.replicas = 2
acks = allWhat exception will be generated if two brokers are down due to network delay?

• A.NetworkException
• B.NotEnoughReplicasException
• C.NotCoordinatorException
• D.NotLeaderForPartitionException

Which two statements about Kafka Connect Single Message Transforms (SMTs) are correct?
(Select two.)

• A.Masking data is a good example of an SMT.
• B.Multiple SMTs can be chained together and act on source or sink messages.
• C.SMT functionality is included within Kafka Connect converters.
• D.SMTs are often used to join multiple records from a source data system into a single Kafka record.
