MB-230 Extend Customer Service Practice Question
A Dynamics 365 Customer Service organization uses Unified Routing. A developer needs to extend routing by calling an external AI service to determine the priority of incoming cases before they are routed to queues. The solution must minimize custom code and be maintainable within the Power Platform. What should the consultant implement?
⚠ Common exam trap
The trap here is assuming that plug-ins or workflows are needed to integrate external logic into routing, when Unified Routing provides a native low-code extension point through Power Automate flows in custom routing rules.

Correct answer & explanation
✓
Create a custom routing rule with a Power Automate flow that calls the external AI service and sets a routing attribute.
Unified Routing allows custom routing rules that can call Power Automate flows. This is the recommended low-code extensibility point for integrating external services into the routing decision. The flow can call the AI service and return a value that sets a routing attribute, which the routing engine then uses to determine the queue and priority. This keeps the solution maintainable and within the Power Platform.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a real-time workflow that triggers on case creation and calls the external AI service using a custom workflow activity.
Why it's wrong here
Real-time workflows with custom workflow activities require custom code (the activity) and are deprecated in favor of Power Automate. They also do not integrate with Unified Routing's decision process; they run on the case record but do not influence routing attributes used by the routing engine. This approach is less aligned with the low-code requirement and current best practices.
- ✗
Write a plug-in registered on the Case entity's Create message that calls the external AI service and updates the case priority.
Why it's wrong here
A plug-in can call external services, but it requires custom code development and deployment, which contradicts the requirement to minimize custom code. Plug-ins also run synchronously within the platform's transaction, and calling an external AI service could cause timeouts or performance issues. This approach is less maintainable than a Power Automate flow and does not directly integrate with Unified Routing's decision logic.
- ✗
Configure an assignment rule that uses a custom JavaScript web resource to call the AI service and set the priority.
Why it's wrong here
Assignment rules in Unified Routing do not support JavaScript web resources. They evaluate conditions based on attributes and route to queues. JavaScript runs client-side on forms, not server-side during routing. This option misinterprets the extensibility points of Unified Routing and would not execute when a case is routed.
- ✓
Create a custom routing rule with a Power Automate flow that calls the external AI service and sets a routing attribute.
Why this is correct
Unified Routing supports custom routing rules that can invoke Power Automate flows. By using a flow, you can call the external AI service via an HTTP action or custom connector, then return a value that sets a routing attribute such as priority. This approach uses low-code tools, is maintainable, and integrates directly into the routing decision process without writing plug-ins or custom code.
