You have created an application for real-time analysis of website clickstreams using Kinesis Data Streams. There are multiple EC2 instance acting as consumers which process data & save analyzed data in Amazon DynamoDB using Enhanced Fan-out. Which of the following can be achieved using Enhanced Fan-out for each registered consumer?

Answer options:

A.Enables registered consumers to receive records with a throughput of up to 2 MiB of data per second for all shards with an average message propagation delay of 70 ms for all consumers.
B.Enables registered consumers to receive records with a throughput of up to 2 MiB of data per second per shard with an average message propagation delay of 70 ms for all consumers.
C.Enables registered consumers to receive records with a throughput of a total of 2 MiB of data per second per shard shared between all consumers with an average message propagation delay of 70 ms for all consumers.
D.Enables registered consumers to receive records with a throughput of up to 2 MiB of data per second per shard with an average message propagation delay of 70 ms which surges based upon many consumers paralleling accessing the shard.

Correct Answer – B
With Enhanced Fan-out, each registered consumer gets 2MiB/sec throughput per shard & message propagation delay of 70 ms independent of other consumers.
Option A is incorrect as With Enhanced Fan-out, each registered consumer gets 2MiB/sec throughput per shard & not shared for all shards.
Option C is incorrect as With Enhanced Fan-out, each registered consumer gets 2MiB/sec throughput per shard irrespective of the total number of consumers.
Option D is incorrect as With Enhanced Fan-out, each registered consumer gets a message propagation delay of 70 ms independent of other consumers accessing the shard.
