Answer: Amazon SQS is highly scalable and does not need any intervention to handle the expected high volumes
Correct option: Amazon SQS is highly scalable and does not need any intervention to handle the expected high volumes Amazon SQS leverages the AWS cloud to dynamically scale, based on demand. SQS scales elastically with your application so you don't have to worry about capacity planning and pre-provisioning. For most standard queues (depending on queue traffic and message backlog), there can be a maximum of approximately 120,000 inflight messages (received from a queue by a consumer, but not yet deleted from the queue).
