AWS Certified Developer Associate DVA-C02 Practice Question

A developer is building a serverless application that must process new user registrations in real time. The user data is stored in an Amazon DynamoDB table. The requirement is to automatically trigger a piece of code whenever a new user item is created in the table. Which of the following is the most direct and event-driven approach to meet this requirement?

  • Enable DynamoDB Streams on the table and configure it as a trigger for a Lambda function.

  • Configure an Amazon SQS queue to poll the DynamoDB table and then trigger a Lambda function.

  • Use an Amazon EventBridge (CloudWatch Events) rule with a schedule to invoke a Lambda function that queries the table.

  • Write a cron job on an Amazon EC2 instance to scan the DynamoDB table for new items every minute.
