Question $22$

'You are working as a Lead Solutions Architect for a financial company. Your application is hosted in an Amazon ECS Cluster, which processes a large stream of intra$-$day data and stores the generated result to a DynamoDB database. To comply with the financial regulatory policy, you have to design a system which will detect new entries in DynamoDB table and automatically run tests using a Lambda function.

Which of the following options can satisfy the requirement with minimal configuration?

Detect new entries in the DynamoDB table using Systems Manager Automation that automatically invokes the Lambda function for processing.

Set up DynamoDB Streams to detect the new entries and automatically trigger the Lambda function.

Run the Lambda function using SNS each time each time the ECS'cluster successfully adds data to the DynamoDB table.

Set up CloudWatch alarm to automatically trigger the Lambda function for the new entry in the DynamoDB table.
