Answer is correct. Queue Storage does not provide transactional support and Event Hub can't be configured to store events for infinite time.

Event Hub can be configured to store events, with Event Hub Capture. Makes the answer still correct though. https://docs.microsoft.com/en-us/azure/event-hubs/event-hubs-capture-overview

Event hubs (with capture) are not supposed to retain data forever. https://docs.microsoft.com/en-us/azure/event-hubs/event-hubs-faq#what-is-the-maximum-retention-period-for-events

The stress is on 'messaging' which Event Hub is not (it's eventing)

Agree, answer is correct, but I think duplicate detection is the key phrase.

Selected Answer: AB

The two technologies that meet the requirements are: B. Azure Service Bus Queue: Azure Service Bus Queues provide transactional support and duplicate detection. However, they do not natively support storing messages for an unlimited period of time. The maximum message retention period is 7 days, but with the use of forwarding, you could potentially extend this. A. Azure Service Bus Topic: Azure Service Bus Topics also provide transactional support and duplicate detection. Topics are similar to queues, but they allow one message to be received by multiple subscriptions. Like queues, they do not natively support storing messages for an unlimited period of time, but with forwarding and subscriptions, you could potentially extend this.
