[All AWS Certified Data Engineer - Associate DEA-C01 Questions]

A data engineer must manage the ingestion of real-time streaming data into AWS. The data engineer wants to perform real-time analytics on the incoming streaming data by using time-based aggregations over a window of up to 30 minutes. The data engineer needs a solution that is highly fault tolerant.
Which solution will meet these requirements with the LEAST operational overhead?

A. Use an AWS Lambda function that includes both the business and the analytics logic to perform time-based aggregations over a window of up to 30 minutes for the data in Amazon Kinesis Data Streams.
B. Use Amazon Managed Service for Apache Flink (previously known as Amazon Kinesis Data Analytics) to analyze the data that might occasionally contain duplicates by using multiple types of aggregations.
C. Use an AWS Lambda function that includes both the business and the analytics logic to perform aggregations for a tumbling window of up to 30 minutes, based on the event timestamp.
D. Use Amazon Managed Service for Apache Flink (previously known as Amazon Kinesis Data Analytics) to analyze the data by using multiple types of aggregations to perform time-based analytics over a window of up to 30 minutes.

D. Amazon Managed Service for Apache Flink for Time-Based Analytics over 30 Minutes: This option correctly identifies the use of Amazon Managed Service for Apache Flink for performing time-based analytics over a window of up to 30 minutes. Apache Flink is adept at handling such scenarios, providing capabilities for complex event processing, time-windowed aggregations, and maintaining state over time. This option would offer high fault tolerance and minimal operational overhead due to the managed nature of the service.
