   A point-of-sale (POS) system must validate a customer's credit limit in real time before completing a sale. The validation must be performed in Dynamics 365 Finance and Operations and the POS must receive an immediate approval or rejection. Which integration approach should you use?

   • ASend the credit check request to an Azure Service Bus queue and process it asynchronously.
   • BCall a custom synchronous OData action that performs the credit check and returns the result in the HTTP response.
   • CUse the Data Management Framework to export the customer's credit limit to a file that the POS reads.
   • DUse a recurring batch job to update the POS system with credit limit changes every hour.

   A company is integrating its external e-commerce platform with Dynamics 365 Finance and Operations. The platform needs to check product availability in real time and also submit orders. The company has two requirements: (1) availability checks must return within 1 second, and (2) order submissions must not block the platform. Which combination of integration patterns should the developer use?

   • AUse synchronous OData calls for both availability checks and order submissions.
   • BUse a nightly batch for availability checks and a synchronous call for order submissions.
   • CUse an asynchronous message queue for both availability checks and order submissions.
   • DUse a synchronous OData call for availability checks and an asynchronous message queue for order submissions.

   An organization is integrating an external warehouse management system (WMS) with Dynamics 365 Finance and Operations. The WMS needs to confirm goods receipt in real time to update inventory, but the WMS also sends large batches of historical inventory adjustments that are not time-sensitive. Which hybrid approach should you implement?

   • AUse OData for the real-time goods receipt confirmations and the Data Management Framework for the historical adjustments.
   • BUse OData for both the real-time confirmations and the historical adjustments.
   • CUse Azure Service Bus for the real-time confirmations and OData for the historical adjustments.
   • DUse the Data Management Framework for both the real-time confirmations and the historical adjustments.

   A company is designing an integration between an external e-commerce site and Dynamics 365 Finance and Operations. The e-commerce site needs to check product availability in real time when a customer views a product. The developer must choose between a synchronous OData call and an asynchronous message-based approach. What is the primary reason to choose the synchronous approach?

   • AIt allows the integration to continue even if the Finance and Operations system is unavailable.
   • BIt reduces the load on the Finance and Operations system by processing requests in batches.
   • CIt provides an immediate response to the e-commerce site, ensuring the customer sees current availability.
   • DIt ensures that the e-commerce site does not have to wait for the response.

   A company has a custom mobile app that needs to look up customer account details from Dynamics 365 Finance and Operations. The lookup must return the data within a few seconds. The app is used by field agents with intermittent connectivity. Which integration pattern should the developer recommend?

   • AUse an asynchronous message queue to request the data and receive it later.
   • BUse the Data Management Framework to import the lookup request and then export the result.
   • CUse a synchronous OData call from the mobile app to retrieve the customer details.
   • DUse a recurring data job to export customer data to the mobile app periodically.
