B. Client-side script
Explanation
This item tests the candidate’s knowledge of where to run business logic, including cloud computing, client-side processing, business rules, plug-ins, and Power Automate.
For logic to run immediately when a field on a model-driven app is changed, the logic must run synchronously within the app. The scope of a business rule can be set to run within a model-driven app form and will run immediately when a field in the form is changed. A client-side script can be added to the OnChange event of a form field and so will run immediately when a field in the form is changed.
Automated low-code plug-ins run when the row is saved to Microsoft Dataverse. Power Automate cloud flows are run asynchronously after the row has been saved. Power Fx is not available in model-driven app forms.
