AWS Certified Solutions Architect Associate SAA-C03 Practice Question

Amazon Simple Queue Service (SQS) is the correct choice because it provides a managed message queue that can help to decouple the components of an application. It can handle sporadic data bursts by storing messages until the processing microservice is ready to receive them, ensuring that every message is processed at least once. Additionally, SQS automatically scales with the number of messages, which addresses the requirement for scalability with message volume. AWS Transfer Family is primarily used for transferring files into and out of AWS, creating a secure data ingestion pipeline. AWS Lambda is a compute service that runs code in response to events but does not provide native queuing functionality to ensure ordered processing and at-least-once delivery. AWS Secrets Manager is focused on secret management and would not facilitate message queuing or processing.
