Selected Answer: D

Only one consumer (DB), so SNS no need .. as it makes sense only for multiple consumers. So A and B Out... Between C and D, C asks for queuing DB Connections ..which can be done but thats not regular...so D which drains (empties via msg processing within Visibility time out and deleting msgs from SQS).
