Question:
Which of the following advanced features of Azure Service Bus creates a first-in, first-out (FIFO) guarantee?
Answer:

Scheduled delivery: Messages can be submitted to a queue or topic for delayed processing, but that doesn't guarantee a FIFO.
A transaction groups two or more operations together into an execution scope.
