AWS Certified Developer Associate DVA-C02 Practice Question
A developer needs to process a stream of incoming data and update a DynamoDB table accordingly. The developer has decided to use a Lambda function to process the batches of records as they arrive and update DynamoDB. Which AWS service should be used to trigger the Lambda function in response to the incoming data stream?
Utilize Amazon SQS to queue the data and trigger the Lambda function.
Employ Amazon SNS to publish messages that trigger the Lambda function.
Use Amazon Kinesis Data Streams to trigger the Lambda function.
Configure Amazon S3 event notifications to trigger the Lambda function.
AWS Lambda can be directly triggered by Amazon DynamoDB Streams when data modification occurs in the DynamoDB table, enabling real-time processing of the changes. However, the scenario described involves processing a stream of incoming data, not changes to a DynamoDB table. Amazon Kinesis is a service for real-time processing of large, streaming data, and Lambda functions can be triggered by Kinesis Data Streams. Therefore, using Amazon Kinesis Data Streams to trigger the Lambda function is the correct answer because it aligns with the requirement of processing incoming data stream.
