Multiple Choice

An organization has two Amazon EC2 instances: The first is running an ordering application and an inventory application. The second is running a queuing system. During certain times of the year, several thousand orders are placed per second. Some orders were lost when the queuing system was down. Also, the organization's inventory application has the incorrect quantity of products because some orders were processed twice.
