Choose the single best answer.

B.Queue Storage with an assumption of native broker sessions and dead-lettering
C.Event Hubs partition ordering and checkpoints used as business-queue settlement
D.Service Bus with suitable sessions and completion/dead-letter handling

Show the answer and explanation

✓ Correct answer

Service Bus with suitable sessions and completion/dead-letter handling

Service Bus offers the required business-messaging mechanisms, including sessions for related ordering and completion/dead-letter handling. Event Hubs ordering and checkpoints are stream-processing mechanisms rather than the required queue settlement model. Queue Storage requires application handling and does not supply the same native sessions/dead-letter features. Event Grid notifications do not provide the specified ordered transactional business queue. Source guide: PDF page(s) 66.
