Answer is C. https://aws.amazon.com/sqs/features/

A. Use one SQS FIFO queue. Assign a higher priority to the paid photos so they are processed first. Using a single SQS FIFO (First-In-First-Out) queue allows for ordered processing of messages, ensuring that the messages are processed in the order they were sent. By assigning a higher priority to the paid photos, you can ensure that they are processed before the free photos.

Answer from ChatGPT Option A. Use one SQS FIFO queue. Assign a higher priority to the paid photos so they are processed first. Using one Amazon SQS FIFO queue with message prioritization is the recommended approach for this scenario. The paid photo messages can be assigned a higher priority than free photo messages so they are processed first. FIFO queues ensure that messages are processed in the order they are received and are a good fit for scenarios where message sequencing and deduplication is important. This approach also simplifies the configuration and reduces costs by using a single queue.

In standard Q messages can be processed more than once so how thats correct?

message prioritise is not an option in SQS.

The answer is C. Priority: Use separate queues to provide prioritization of work. https://aws.amazon.com/sqs/features/

cccc- 2 queues and prioritize paid

B is wrong, there is no short polling... Ans is C

I think its c

I think B is the answer. Priority: Use separate queues to provide prioritization of work. 2 different FIFO queues would logically ensure that those who upload first get the output first. A is out because we do not have priority as a configurable property. Further, long polling would help: When a consumer requests messages from the queue, it can optionally “wait” for messages to arrive if there are none in the queue. LongPolling decreases the number of API callsmade to SQS while increasing the efficiency and latency of your application. In D,just one queue will not help separate premium content. Settign visibility timeout to 0 would likely result in duplicates as message will not be processed so fast and SQS will resend. Between B and C, perhaps B looks like better choice.

Answers are D and E

'C' is the correct answer, C. Use two SQS standard queues: one for paid and one for free. Configure Amazon EC2 instances to prioritize polling for the paid queue over the free queue. Explanation AWS recommend using separate queues when you need to provide prioritization of work. The logic can then be implemented at the application layer to prioritize the queue for the paid photos over the queue for the free photos.
