The fan out feature allows consumers to receive data from a stream with dedicated throughput

The correct answer is A. Here is why: Amazon Kinesis Data Streams is designed for real-time streaming data. The PutRecords API is efficient for sending multiple records to Kinesis in a single call, which is good for optimizing throughput from mobile devices. The enhanced fan-out feature allows multiple consumers to read from the same stream with dedicated throughput for each consumer, which meets the requirement of dedicated throughput for each internal consumer. This option uses uses Kinesis Data Streams for real-time processing, optimizes throughput from mobile devices with the PutRecords API, and provides dedicated throughput for each consumer using the enhanced fan-out feature.

A is best, but I think it was supposed to be a SHARD for each consumer. B - doesn't make any sense C - Firehose does not have enhanced fan-out afaik D - does not have the dedicated throughput as it doesn't use enhanced fan-out with KDS

https://docs.aws.amazon.com/streams/latest/dev/kpl-with-firehose.html KPL does work with firehose

Seems to be A - Since KPL does not work into firehouse and only streams, and additionally the dedicated throughput is solved through fan-out
