Add the prompt to the app: Data. Access the prompt results: Predict().

A preexisting custom prompt is added to a canvas app through the Data pane, in the same general way that a connector or AI model is added as an application data source. Adding it as media, a control, or a variable would not register the prompt as a callable app resource. After it is available in the app, Power Fx invokes it by using the prompt ' s Predict method and passes the current input values required by the prompt. The returned record contains the generated result, which can be assigned to a variable, collected, displayed in a control, or used in later formulas. The call should normally be placed in an event such as a button ' s OnSelect property so that it runs only when intended. Makers should also handle blank inputs and prediction errors and should avoid unnecessarily repeated calls because AI consumption is metered. Microsoft Learn identifies consuming prompts in apps and adding inputs to prompts as AB-410 objectives and documents calling a prompt from Power Apps through Power Fx.

Accounts classification — Choice column; Contacts engagement tier — Choice column; Lookup performance and uniqueness — Alternate key

Both classification requirements should use Choice columns. An account classification and a contact engagement tier are controlled categorical values; Choice columns provide a governed option list, validation, labels, and consistent filtering. If the same option set is needed across tables, the maker should define a reusable global choice and reference it from both columns. A Customer column is a special polymorphic lookup that can reference an Account or Contact row; it represents a customer relationship, not a tier or classification. The lookup-performance and uniqueness requirement should use an alternate key. An alternate key creates a Dataverse key definition over selected columns so integrations can identify a row by business data and Dataverse can enforce uniqueness. The original embedded answer image is intentionally preserved, but the Customer-column selection for engagement tier is technically incorrect; the verified selection is Choice column. The Study Guide covers this under “create and modify columns” and “configure table properties.” The final mapping is therefore Choice column for both categorical attributes and Alternate key for the lookup/uniqueness requirement.

A custom connector is required to integrate with the third-party AI service because the integration needs a defined authentication scheme and custom request handling. The connector wraps the service’s API as named operations, with host information, paths, methods, headers, parameters, request bodies, and response schemas. Power Automate or Power Apps can then call those operations through governed connections instead of reconstructing raw requests in every solution. Power Fx is an expression language and does not by itself define or secure an external API contract. Microsoft 365 Copilot chat is a user productivity experience, not a Dataverse integration mechanism. An environment variable can store deployment-specific configuration such as a base URL or identifier, but it neither authenticates nor sends the API request. The connector should be packaged in a solution, use the service’s supported API key or OAuth design, and comply with data loss prevention policies. This directly aligns with the Study Guide cloud-flow objective “evaluate and recommend connectors” and Microsoft’s custom connector architecture.

Country/region population — Power Automate flow; Passport expiration visibility — Business rule

The Country/region population should use a Power Automate flow, while passport-expiration visibility should use a business rule. A flow triggered by the row change can inspect the selected language values, set US when English is present, and leave Country/region blank when Other is selected. The passport requirement is ordinary form behavior: when Passport ownership equals Yes, a business rule can show the expiration-date control; otherwise it can hide it. That gives immediate client-side feedback with minimal code. The original embedded answer image assigns both requirements to business rules; it is preserved unchanged, but the verified first mapping is Power Automate flow. The flow must avoid a trigger loop by filtering changed columns or checking whether an update is necessary. The Study Guide covers business rules, cloud-flow triggers, and business-logic use-case evaluation. The corrected mapping respects both feature support and execution timing.
