MB-910 Describe Dynamics 365 Sales Practice Question
A company uses Dynamics 365 Sales and wants to ensure that when a sales rep creates a new order, the system automatically checks product inventory before allowing the order to be submitted. What is the best approach?
⚠ Common exam trap
A common mix-up: candidates confuse real-time workflows with Power Automate flows, assuming workflows can handle external integrations, but workflows are limited to internal Dynamics 365 operations and cannot call external APIs.

Correct answer & explanation
✓
Use Power Automate to call an inventory API on order creation
Power Automate can trigger an HTTP call to an external inventory API when an order is created in Dynamics 365 Sales, allowing real-time validation of product stock before the order is submitted. This approach provides the necessary integration with an external inventory system, which is not natively available in Dynamics 365 Sales. Workflows and calculated fields cannot perform external API calls, and Business Process Flows do not enforce real-time inventory checks.
