AWS Certified Developer Associate DVA-C02 Practice Question

Which design pattern can improve the resiliency of a microservices architecture by using a publish/subscribe service that distributes each event concurrently to multiple independent message queues so that every consumer processes the event in isolation?

  • Expose every microservice through synchronous REST API calls and invoke them sequentially from the producer service.

  • Store all events in a shared relational database table that each microservice queries for new records.

  • Send every message to a single Amazon SQS queue that all consumer services poll in turn.

  • Configure an Amazon SNS topic that fans out each published message to a dedicated Amazon SQS queue for every consumer microservice.
