The client will have multiple options for customers to choose the level of service they want to pay for.
The client has asked how he can design the application to process the orders in a prioritized way based on the level of service the customer has chosen?CorrectIncorrect

Question 7 of 10
A web application receives order processing information from customers and places the messages on an Amazon SQS queue.
