DVA-C02 Question 337
Select 3You are developing a serverless application on AWS and need to create real-time data visualizations for metrics stored in an Amazon DynamoDB table. The visualizations should automatically update as new data is added to the table. Which combination of services and features should you use to achieve this?
- A
Amazon DynamoDB Streams to capture table updates
- B
AWS Lambda to process changes from DynamoDB Streams and send data to Amazon CloudWatch
- C
Amazon QuickSight to build interactive dashboards and visualizations
- D
Amazon S3 to store processed data for visualization
- E
Amazon Kinesis Data Firehose to stream data from DynamoDB directly into Amazon QuickSight
Show answer and explanation
Correct answers: A, B, C
Explanation
To achieve real-time data visualization with data stored in DynamoDB, you can use DynamoDB Streams to capture table changes, AWS Lambda to process the stream data, and Amazon QuickSight to create and update visualizations. This combination allows you to build an automated, serverless pipeline for real-time dashboards. Other services like Amazon S3 and Amazon Kinesis Data Firehose are not necessary for this specific scenario.
- A. Correct.
Correct. DynamoDB Streams captures real-time changes to the table, making it possible to process new data and update visualizations automatically.
- B. Correct.
Correct. AWS Lambda can process the data from DynamoDB Streams and send it to a service like Amazon CloudWatch or prepare it for visualization in Amazon QuickSight.
- C. Correct.
Correct. Amazon QuickSight is a fully managed business intelligence service that can create interactive dashboards and visualizations.
- D. Incorrect.
Incorrect. While Amazon S3 is useful for storing processed data, it is not necessary in this scenario as the focus is on real-time updates to visualizations.
- E. Incorrect.
Incorrect. Amazon Kinesis Data Firehose does not integrate directly with DynamoDB, and it is not required for this use case since DynamoDB Streams already provides the real-time data feed.
