[All AWS Certified Developer - Associate DVA-C02 Questions]

An online food company provides an Amazon API Gateway HTTP API to receive orders for partners. The API is integrated with an AWS Lambda function. The Lambda function stores the orders in an Amazon DynamoDB table.

The company expects to onboard additional partners. Some of the partners require additional Lambda functions to receive orders. The company has created an Amazon S3 bucket. The company needs to store all orders and updates in the S3 bucket for future analysis.

How can the developer ensure that all orders and updates are stored to Amazon S3 with the LEAST development effort?

A. Create a new Lambda function and a new API Gateway API endpoint. Configure the new Lambda function to write to the S3 bucket. Modify the original Lambda function to post updates to the new API endpoint.
B. Use Amazon Kinesis Data Streams to create a new data stream. Modify the Lambda function to publish orders to the data stream. Configure the data stream to write to the S3 bucket.
C. Enable DynamoDB Streams on the DynamoDB table. Create a new Lambda function. Associate the stream’s Amazon Resource Name (ARN) with the Lambda function. Configure the Lambda function to write to the S3 bucket as records appear in the table's stream.
D. Modify the Lambda function to publish to a new Amazon Simple Notification Service (Amazon SNS) topic as the Lambda function receives orders. Subscribe a new Lambda function to the topic. Configure the new Lambda function to write to the S3 bucket as updates come through the topic.

By enabling DynamoDB Streams on the DynamoDB table, you can capture changes (orders and updates) to the table. Whenever a new order or an update is made to the table, a stream record is generated. You can then create a new Lambda function, associate the stream's ARN with this Lambda function, and configure it to write the stream records (orders and updates) to the S3 bucket. This approach leverages built-in features of DynamoDB and Lambda, minimizing the development effort required to achieve the desired outcome.

This is a streamlined and effective approach. Enabling DynamoDB Streams captures modifications to the DynamoDB table (such as new orders) and triggers a new Lambda function. This function can then write these changes to the S3 bucket. This approach requires minimal changes to the existing setup and leverages the integration between DynamoDB Streams and Lambda.

Selected Answer: C

Enabling DynamoDB Streams on the existing DynamoDB table and associating a new Lambda function to it would be a straightforward way to capture all changes (new orders and updates) in the DynamoDB table. The new Lambda function would automatically be triggered when a new record appears in the table's stream and could be configured to write this data to the S3 bucket. This is likely the least effort-intensive approach for meeting the requirement.
