Question 46/108
Universal Containers has Logistics Engineers that observe a near real-time dashboard in Salesforce of shipping containers that are in transit. Without leaving the dashboard, an Engineer can select a container to request an updated status on that container. These requests are handled by a proprietary shipping system that queues the requests to send to each container. Containers are connected devices and check in with the shipping system every 30 seconds to receive any status requests.

Shipping system queue the request so user can not wait for reply => Fire & Forget then Update UI when have data change.
The integration pattern needed in this scenario would be D. Remote Process Invocation-Request and Reply.
In this pattern, the Logistics Engineer would make a request for updated status on a container through the Salesforce dashboard. The request would then be sent to the shipping system, which would queue the request and send it to the relevant container. The container would respond with the updated status, which would then be received by the shipping system and passed back to Salesforce to update the dashboard.
This pattern allows for the shipping system to receive a specific request and return a specific response, which is important in this scenario because the Logistics Engineer needs to receive updated information on a specific container in near real-time. The "Request and Reply" aspect of this pattern ensures that the correct information is returned to the correct request.
