question 12

Multiple Choice

The company must reduce this latency to 500 milliseconds. Which solution meets these requirements?

• A) Use enhanced fan-out in Kinesis Data Streams.
• B) Increase the number of shards for the Kinesis data stream.
• C) Reduce the propagation delay by overriding the KCL default settings.
• D) Develop consumers by using Amazon Kinesis Data Firehose.
