A company is building an IoT application that receives millions of sensor readings per minute. The data must be ingested in real-time, ordered by the time it was received, and processed by multiple independent consumer applications simultaneously. The data must be retained for 7 days.<br/><br/>Which TWO statements about the appropriate AWS service are correct? (Select TWO.)
Answer options:
A.
Amazon SQS FIFO should be used.
B.
Amazon Kinesis Data Streams should be used.
C.
The service deletes data immediately after it is read by a consumer.
D.
The service allows multiple consumers to read the same data concurrently.
E.
Amazon SNS should be used.
How to approach this question
Differentiate between message queues (SQS) and data streams (Kinesis).
Full Answer
Amazon Kinesis Data Streams should be used.<br/>The service allows multiple consumers to read the same data concurrently.
Amazon Kinesis Data Streams is a serverless streaming data service that makes it easy to capture, process, and store data streams at any scale. Unlike SQS, Kinesis retains data for a retention period (up to 365 days), allowing multiple consumers to process the same data concurrently.
Common mistakes
Choosing SQS, which deletes messages after processing, preventing multiple independent consumers from reading the entire dataset.
