AB-410 Practice Test 4 — 25 Questions

Question 1

You are building a Power Automate flow that needs to trigger whenever a row is added to a Dataverse table. Which trigger should you select to ensure the flow runs in near real-time?

Accepted Answer

When a row is added, modified or deleted. The Dataverse trigger 'When a row is added, modified or deleted' is a webhook-based trigger that fires in near real-time when a table row changes, making it the correct choice for event-driven flows. It supports filtering by scope (business unit, user, organization) and by specific columns to reduce unnecessary runs.

Answer

When a row is selected

Answer

List rows

Answer

Recurrence

Question 2

A developer needs to ensure that a custom field value is validated before the record is saved to the database. Where should this logic be placed?

Accepted Answer

Synchronous Plugin. A synchronous plugin executes within the Dataverse pipeline before the record is committed to the database, making it the correct place to enforce server-side validation that must block the save. Because it runs synchronously in the Pre-Operation or Pre-Validation stage, it can throw an InvalidPluginExecutionException to prevent the save if validation fails.

Client-side JavaScript

Answer

Business Rule on the form

Question 3

You notice that an image in your canvas app is blurry. What should you check to ensure it displays at high quality?

Accepted Answer

The Image property and control dimensions. Image quality in a canvas app depends on the source image resolution and how the Image property and control dimensions are configured. If the control is stretched beyond the image's native resolution, or if the Image property points to a low-resolution asset, the result is blurriness. Checking these settings ensures the image is displayed at its intended size and quality.

Answer

The app background color

Answer

The number of data sources

Answer

The app theme

Question 4

You are building a solution that includes a flow and an app. Where should you save these components to ensure they can be easily moved between environments?

Accepted Answer

A Solution. A Solution is the container that packages components like flows, apps, tables, and more for transport between environments. It tracks dependencies and allows export/import as a managed or unmanaged ZIP file, enabling ALM (Application Lifecycle Management). Saving components in a solution ensures they are portable and can be versioned, unlike saving them directly in the default environment or personal folders.

Answer

My Flows

Answer

Dataverse tables

Answer

Default environment

Question 5

A user has 'User' level access to a table. They create a record. Who is the owner of the record?

Accepted Answer

The user who created the record. In Dataverse, when a user with at least User-level access creates a record, that user is automatically set as the record's owner. Ownership is a core security concept in Dataverse that determines who can access and manage the record, and it is assigned at creation time to the creating user unless explicitly reassigned (e.g., to a team or another user).

Answer

The Business Unit Manager

Answer

The record has no owner

Answer

The System Administrator

Question 6

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 7

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 8

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 9

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 10

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 11

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 12

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 13

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 14

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 15

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

Question 16

You are using AI Hub to categorize customer support emails. You need to ensure the model processes only emails with high sentiment scores. Where do you configure this logic?

Accepted Answer

Within a Condition control in Power Automate. AI Hub provides prebuilt AI models, but the logic that decides which emails to process based on sentiment scores belongs in the orchestration layer. In Power Automate, a Condition control can evaluate the sentiment score returned by the AI model and branch accordingly, ensuring only high-sentiment emails proceed. This keeps the AI model generic and the business logic external and maintainable.

Answer

Inside the AI Hub model settings

Answer

In the Dataverse business rule

Answer

In the Copilot Studio agent manifest

Question 17

A user needs to see records based on specific criteria. Which object should you configure?

Accepted Answer

View. A View in Dataverse (or model-driven apps) defines which records are displayed and how they are filtered, sorted, and columned. Views are the standard object for showing a filtered subset of records based on criteria, such as 'Active Accounts' or 'My Open Opportunities'. Configuring a view with filter conditions is the correct way to let a user see records matching specific criteria.

Answer

Form

Answer

Relationship

Answer

Chart

Question 18

Which TWO items are visible in the Power Apps 'Tree View' pane?

Accepted Answer

Screens. In Power Apps Studio, the Tree View pane displays the hierarchical structure of the app's UI, so option B (Screens) is correct because every screen in the app appears as a top-level node in that hierarchy. Option D (Controls) is also correct because the controls placed on each screen (such as labels, buttons, galleries, and containers) are shown nested under their parent screen within the Tree View. Option A (User profiles) is incorrect because user account information is managed in Microsoft 365/admin centers, not in the app-authoring Tree View. Option C (Dataverse environments) is incorrect because environments are managed in the Power Platform admin center, not displayed in the Tree View. Option E (Power Automate flows) is incorrect because flows are separate Power Automate resources that can be called from an app but are not listed as nodes in the Tree View pane.

Answer

User profiles

Answer

Dataverse environments

Answer

Power Automate flows

Question 19

You are designing a Dataverse table to store customer orders. You need to ensure that each order is automatically assigned a unique, sequential order number that users can easily reference. The number should be generated when a new record is created and should not be editable by users. What should you use?

Accepted Answer

An autonumber column. An autonumber column is designed to automatically generate unique, sequential numbers for new records. It is read-only, ensuring users cannot edit the value. This makes it the perfect choice for order numbers that need to be unique and easily referenced. Other column types cannot provide sequential numbering without complex workarounds and may not guarantee uniqueness.

Answer

A calculated column that concatenates the creation date and a random number

Answer

A text column with a business rule that sets its value

Answer

A rollup column that counts existing orders

Question 20

Which tool in the Power Apps environment allows you to test your canvas app without publishing it?

Accepted Answer

Preview button. The Preview button (or F5) runs the canvas app in a preview/play mode so you can test its behavior and interactions without publishing it to users. This lets makers validate functionality, formulas, and navigation in a safe environment. Publishing is a separate step that distributes the app to end users.

Answer

Publish button

Answer

App checker

Answer

Data pane
