AB-410 Practice Test 9 — 10 Questions

Question 1

You want to use AI Builder to predict whether a customer will churn. You have a Dataverse table with historical churn data. What is the first step?

Accepted Answer

Create a Prediction model in AI Builder.. AI Builder Prediction models are designed for binary or multiclass classification and regression scenarios like churn prediction. The first step after confirming historical data in Dataverse is to create a Prediction model in AI Builder, which then guides you through selecting the table, outcome column, and training. This is the correct starting point for a custom AI model.

Answer

Create an object detection model.

Answer

Export the data to Excel.

Answer

Train a model in the AI Hub.

Question 2

You are designing a Dataverse solution for a hospital. You need to track patient visits and the medications prescribed during each visit. A visit can have multiple medications, and a medication can be prescribed in multiple visits. You also need to store the dosage and frequency for each medication prescribed in a visit. What is the most appropriate way to model this relationship?

Accepted Answer

Create a new table called 'Prescription' with a many-to-one relationship to Visit and a many-to-one relationship to Medication. Add columns for dosage and frequency to the Prescription table.. The correct solution is to create an intersect table (Prescription) with many-to-one relationships to both Visit and Medication, and place the dosage and frequency columns on that intersect table. This captures the many-to-many relationship and allows unique attributes for each association. The other options either misplace the attributes or use an incorrect relationship type.

Answer

Create a many-to-many relationship between Visit and Medication, and add custom columns for dosage and frequency on the Visit table.

Answer

Create a many-to-many relationship between Visit and Medication, and add custom columns for dosage and frequency on the Medication table.

Answer

Create a one-to-many relationship from Visit to Medication, and add columns for dosage and frequency on the Visit table.

Question 3

A user needs to see the history of changes made to a record's fields. What feature must be enabled?

Accepted Answer

Auditing. Auditing in Dataverse (and Dynamics 365) is the feature that records field-level and record-level changes, including who changed what, when, and from where. Once auditing is enabled at the environment, table, and column levels, users with appropriate privileges can view the change history for a record.

Answer

Change tracking

Answer

Version control

Answer

Table logging

Question 4

You need to create a Power Automate flow that processes a large batch of documents using an AI Builder custom model. The flow must process each document independently and in parallel to reduce overall processing time. Which action should you use to achieve parallel processing?

Accepted Answer

Apply to each with concurrency control enabled. To process a batch of documents in parallel, use the 'Apply to each' action with concurrency control enabled. This setting allows multiple iterations of the loop to run simultaneously, up to a specified limit. It is the standard way to achieve parallel processing over a dynamic array in Power Automate, significantly reducing the time to process many documents.

Answer

Parallel branch

Answer

Apply to each

Answer

Do until

Question 5

You need to automate a process that extracts data from PDF invoices. Some invoices are multi-page. Which model type should you use?

Accepted Answer

Document processing. Document processing (also called document intelligence) models are purpose-built to extract structured data such as key-value pairs, tables, and text from PDFs and scanned documents, including multi-page invoices. Azure AI Document Intelligence supports prebuilt invoice models that handle multi-page layouts and return structured JSON fields like invoice ID, vendor, and totals. Sentiment analysis, text classification, and object detection do not perform OCR-based field extraction from PDFs.

Answer

Sentiment analysis

Answer

Text classification

Answer

Object detection

Question 6

You are troubleshooting a failed flow run. Where do you find the specific input and output data for each action?

Accepted Answer

In the Run history. The Run history of a flow stores the full execution record of every run, including the exact inputs and outputs of each action, the duration, and any error messages. Clicking into a specific run and then into an action reveals the raw JSON payloads sent and received. This is the authoritative place to diagnose why a particular step produced an unexpected result.

Answer

In the Flow Designer

Answer

In the environment logs

Answer

In the Solution history

Question 7

In a canvas app, you want to allow users to upload images to Dataverse. Which control is best suited for this?

Accepted Answer

Add Picture control. The Add Picture control in Power Apps is specifically designed to let users select and upload image files from their device. It provides a built-in file picker, preview, and exposes the image content via the .Photo property, which can be patched to a Dataverse image or file column.

Answer

Gallery control

Answer

Text input control

Answer

Label control

Question 8

You need to trigger a Cloud Flow from a canvas app when a button is clicked. How do you integrate the flow?

Accepted Answer

Add the flow in the Power Automate pane and call it in the OnSelect property. To trigger a cloud flow from a canvas app, you add the flow to the app via the Power Automate pane (Data > Add data > Power Automate), which makes the flow available as a method. You then call it in the OnSelect property of a button, typically using the syntax FlowName.Run(parameters). This is the standard integration pattern for invoking a flow from a canvas app.

Answer

Use a business rule

Answer

Embed it as a web page

Answer

Add it to the sitemap

Question 9

You need to ensure that a canvas app user can only save their changes if all required fields are filled. What is the most efficient way to validate this?

Accepted Answer

Set the button DisplayMode based on Form.Valid. In Power Apps canvas apps, the Form control exposes a Valid property that is true only when all required fields are filled and all validation rules pass. Binding the submit button's DisplayMode to If(Form1.Valid, DisplayMode.Edit, DisplayMode.Disabled) prevents saving until the form is valid, which is the most efficient built-in approach. This leverages the form's own validation engine instead of duplicating logic.

Answer

Use a timer

Answer

Use a variable

Answer

Write a manual check for each field

Question 10

Which TWO types of components can be included in a Power Apps Solution?

Accepted Answer

Canvas apps. Canvas apps (option C) are a valid Power Apps solution component because solutions package app artifacts such as canvas apps, their connections, and related resources for transport between environments. Model-driven apps (option E) are likewise a supported solution component, since they are built on Dataverse and are explicitly included in solution packaging and ALM. Operating system updates (A) are managed by the OS or update management tooling, not by Power Apps solutions, which only contain app and platform metadata components. Browser extensions (B) are client-side software installed in a browser and are not solution-aware Power Platform components. User personal files (D) are end-user data stored in OneDrive or similar storage, not solution components, which contain configuration and app artifacts rather than personal content.

Answer

Operating system updates

Answer

Browser extensions

Answer

User personal files
