AWS Certified Data Analytics – Specialty — Question 40

A mobile gaming company wants to capture data from its gaming app and make the data available for analysis immediately. The data record size will be approximately 20 KB. The company is concerned about achieving optimal throughput from each device. Additionally, the company wants to develop a data stream processing application with dedicated throughput for each consumer.
Which solution would achieve this goal?

Answer options

• A. Have the app call the PutRecords API to send data to Amazon Kinesis Data Streams. Use the enhanced fan-out feature while consuming the data.
• B. Have the app call the PutRecordBatch API to send data to Amazon Kinesis Data Firehose. Submit a support case to enable dedicated throughput on the account.
• C. Have the app use Amazon Kinesis Producer Library (KPL) to send data to Kinesis Data Firehose. Use the enhanced fan-out feature while consuming the data.
• D. Have the app call the PutRecords API to send data to Amazon Kinesis Data Streams. Host the stream-processing application on Amazon EC2 with Auto Scaling.

Correct answer: A

Explanation

The correct answer is A because using the PutRecords API with Amazon Kinesis Data Streams allows for the efficient sending of data and the enhanced fan-out feature ensures dedicated throughput for consumers. Options B and C do not provide the same level of throughput as Kinesis Data Streams with enhanced fan-out, and option D, while using Kinesis Data Streams, does not utilize the enhanced fan-out feature which is critical for achieving optimal throughput.
