MB-230 Extend Customer Service Practice Question
Exhibit
{
"rule": "Case Priority",
"logic": "if (case.priority == 'Critical') { return 'Escalation_Queue'; }",
"error_handling": "log_to_application_insights"
}Refer to the exhibit. You are implementing a custom plugin to handle case routing. Which method should you use to register this logic within the Dynamics 365 environment?
⚠ Common exam trap
Candidates mistakenly assume plugins can be deployed via simple file upload or standard solution import without the specific registration process required to link them to the Dataverse execution pipeline.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Register the assembly using the Plugin Registration Tool.
Custom plugin logic must be registered using the Plugin Registration Tool (PRT). The PRT allows you to associate your compiled assembly with specific stages of the Dataverse execution pipeline, such as the pre-operation or post-operation stage. This is a critical step because improper registration can lead to performance degradation or infinite loops, which could cripple the entire Customer Service system if not managed correctly.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use the Power Apps portal to upload the code file.
Why it's wrong here
The Power Apps portal does not support the upload or execution of compiled C# plugin assemblies. Plugins must be built and registered via the Plugin Registration Tool to interact correctly with the Dataverse event execution pipeline, which is a core requirement for server-side logic.
- ✓
Register the assembly using the Plugin Registration Tool.
Why this is correct
The Plugin Registration Tool is the standard, supported utility for deploying custom C# code to Dataverse. It allows you to specify the event, entity, and execution stage, ensuring the routing logic triggers reliably and follows the platform's execution model for high-performance server-side operations.
- ✗
Add the code directly to a JavaScript web resource.
Why it's wrong here
JavaScript is a client-side technology and cannot execute server-side logic like custom plugin assemblies. Using JavaScript for server-side routing is impossible because the client-side code is only executed after the data has reached the browser, which is far too late to influence the routing process.
- ✗
Configure an Azure Function in the Power Platform Admin Center.
Why it's wrong here
Azure Functions are external web services. While they can be integrated via webhooks, they are not registered as plugins within the internal Dataverse pipeline. Relying on external functions for core routing logic adds unnecessary complexity and potential points of failure compared to native plugin registration.
