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

A company has an application that processes audio files for different departments. When audio files are saved to an Amazon S3 bucket, an AWS Lambda function receives an event notification and processes the audio input.

A developer needs to update the solution so that the application can process the audio files for each department independently. The application must publish the audio file location for each department to each department's existing Amazon Simple Queue Service (Amazon SQS) queue.

Which solution will meet these requirements with no changes to the Lambda function code?

A. Configure the S3 bucket to send the event notifications to an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe each department’s SQS queue to the SNS topic. Configure subscription filter policies.
B. Update the Lambda function to write the file location to a single shared SQS queue. Configure the shared SQS queue to send the file reference to each department’s SQS queue.
C. Update the Lambda function to send the file location to each department’s SQS queue.
D. Configure the S3 bucket to send the event notifications to each department’s SQS queue.

Selected Answer: A

The correct answer is: A. Configure the S3 bucket to send the event notifications to an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe each department’s SQS queue to the SNS topic. Configure subscription filter policies. Explanation: The goal is to route events from S3 to multiple SQS queues (one per department) without changing the existing Lambda function code. SNS supports fan-out messaging, meaning one message can be sent to multiple subscribers (SQS queues in this case). Subscription filter policies allow messages to be selectively routed to specific queues based on attributes (like department).
