PL-900 Practice Test 49 — 15 Questions

Question 1

Which THREE components are part of Microsoft Power Platform?

Accepted Answer

Power Apps. The three core components of Microsoft Power Platform are Power Apps, Power Automate, and Power BI. While Power Virtual Agents is also a component, the question asks for only three, and these three are the traditional pillars.

Answer

Power Virtual Agents

Answer

Azure DevOps

Question 2

You need to create a Power Automate flow that sends a personalized welcome email to new users when they are added to Microsoft Entra ID. Which trigger should you select?

Accepted Answer

When a user is created (Microsoft Entra ID connector). The correct trigger is 'When a user is created' from the Microsoft Entra ID connector (formerly Azure AD). This trigger initiates a flow when a new user object is created in Microsoft Entra ID, which is ideal for sending a welcome email. Option A is incorrect because it triggers on incoming emails, not on user creation. Option B is for record creation in Dataverse, not for Microsoft Entra ID users. Option C is for file creation in SharePoint, not relevant to user provisioning.

Answer

When a new email arrives (Outlook connector)

Answer

When a record is created (Dataverse connector)

Answer

When a file is created (SharePoint connector)

Question 3

Which THREE actions can be performed by using Power Apps component framework (PCF) in a model-driven app?

Accepted Answer

Implement data validation using Dataverse Web API. All three correct options utilize Power Apps component framework (PCF) to create custom components. The null option involves building a custom visualization component that can call external APIs, such as REST endpoints, to display data from external sources. Option B is correct because PCF components can use the `context.webAPI` methods to interact with Dataverse Web API for data validation beyond simple client-side scripting. Option C is correct because PCF allows building custom input controls with complex UI elements like sliders or maps, which are not possible with out-of-the-box form controls. In contrast, options A, D, and E are incorrect: A uses client-side scripts (JavaScript) not PCF, D is done via form editor layout, and E uses business rules, which are separate features.

Answer

Add a client-side script that runs on field change

Answer

Change the layout of the main form using drag and drop

Answer

Configure a business rule to set field values

Question 4

A user reports they cannot create a new Power Apps app in the default environment. They have a Power Apps license. What is the most likely cause?

Accepted Answer

The user has not been assigned the Environment Maker security role for the default environment.. The most likely cause is that the user has not been assigned the Environment Maker security role for the default environment. Even with a Power Apps license, a user must be explicitly granted the Environment Maker role in a specific environment (including the default environment) to create apps. Without this role, the user can only run apps, not create or edit them.

Answer

A data loss prevention (DLP) policy is blocking app creation.

Answer

The environment has reached its maximum number of apps.

Answer

The user does not have a Power Apps license.

Question 5

Your organization uses Power Automate to automate the creation of support tickets in ServiceNow when a critical alert is triggered in Microsoft Sentinel. The flow uses the 'When a new alert is created' trigger from Sentinel. The flow runs but no tickets are created. You check the Sentinel log and see that alerts are being generated. What should you investigate first?

Accepted Answer

Review the trigger condition or filter query.. The flow uses a trigger condition or filter query that may be set to only fire for specific alert severity levels or types. If the filter is misconfigured, critical alerts might be filtered out even though they are generated in Sentinel. Option A is incorrect because the flow runs, so it is enabled. Option B is incorrect because the issue is not about data connector installation; alerts are appearing in Sentinel logs. Option D is incorrect because if the ServiceNow connector were misconfigured, the flow might fail at a later step, but the issue is likely that the trigger is not firing due to the filter.

Answer

Verify that the flow is enabled.

Answer

Ensure that the Sentinel data connector is properly installed.

Answer

Check if the ServiceNow connector is configured with the correct instance.

Question 6

A Power Automate flow is triggered when a new file is added to a SharePoint document library. The flow should then copy the file to a different library. However, the flow fails when the file name contains a colon (:). What is the most likely reason?

Accepted Answer

The colon character is not allowed in SharePoint file names.. SharePoint does not allow certain characters in file names, including the colon (:). When a file name contains a colon, the flow fails because SharePoint cannot create or copy the file with that character. Option C is incorrect because the connector is not the issue; the problem is the invalid character. Option B is not typical for this specific error, and Option D is unrelated.

Answer

The destination library is full.

Answer

The flow is using the wrong connector.

Answer

The flow does not have permissions to read the source library.

Question 7

You want to automate a business process that requires human interaction for approval. Which type of Power Automate flow should you use?

Accepted Answer

Cloud flow with approval action. A cloud flow with an approval action (commonly called an approval flow) is designed to incorporate human approval steps in an automated process. Option A (Automated cloud flow) is triggered automatically without any manual intervention, so it does not fit the requirement for human interaction. Option B (Business process flow) provides a guided experience for users to follow a standard process but does not handle approvals. Option C (Desktop flow) automates tasks on the desktop (RPA) and is not intended for approval workflows.

Answer

Automated cloud flow

Answer

Business process flow

Answer

Desktop flow

Question 8

A business analyst wants to create a Power Automate flow that runs every Monday at 9 AM to generate a report. Which trigger should they use?

Accepted Answer

Recurrence. The 'Recurrence' trigger allows you to schedule flows to run at specific intervals, such as every Monday at 9 AM. Option A is incorrect because a Power Apps button trigger requires a manual action from a user in a Power App, not automation. Option B is incorrect because 'When a row is added, modified or deleted' triggers on data changes in a data source, not on a schedule. Option C is incorrect because 'When a new email arrives' triggers on incoming emails, not a time-based schedule.

Answer

Power Apps button

Answer

When a row is added, modified or deleted

Answer

When a new email arrives

Question 9

A company's IT department is overwhelmed with password reset requests. They want to allow employees to reset passwords themselves using a conversational interface. Which Power Platform tool should they use?

Accepted Answer

Power Virtual Agents. Power Virtual Agents (C) is the correct tool because it enables the creation of conversational AI chatbots that can handle password reset requests through natural language interactions. It integrates with Azure Active Directory and other identity systems to allow employees to securely reset their own passwords without IT intervention, reducing the helpdesk workload.

Answer

Power BI

Answer

Power Apps

Answer

Power Automate

Question 10

You create a Power Automate flow that runs when a new tweet matches a keyword. What type of trigger does this use?

Accepted Answer

Automated trigger. An automated trigger in Power Automate starts a flow automatically when a specific event occurs, such as a new tweet matching a keyword. Option A is incorrect because a recurrence trigger runs on a schedule, not in response to an event. Option B is incorrect because a manual trigger requires user action to start the flow. Option D is incorrect because a scheduled trigger is another name for a recurrence trigger, which runs at specified times.

Answer

Recurrence trigger

Answer

Manual trigger

Answer

Scheduled trigger

Question 11

A Power Automate flow uses the 'HTTP' action to call an external API. The flow fails intermittently with a 429 (Too Many Requests) error. What is the best practice to handle this?

Accepted Answer

Configure retry policy with exponential backoff. Configuring retry policy with exponential backoff is a best practice for handling HTTP 429 errors, as it automatically retries after increasing delays, reducing server load. Option A is incorrect because using a different endpoint does not address the rate limit on the original API. Option B is incorrect because terminating the flow on error does not handle the error gracefully and may cause data loss. Option D is incorrect because reducing timeout does not prevent or handle rate limiting; it only changes how long the flow waits for a response.

Answer

Switch to a different API endpoint

Answer

Add a 'Terminate' action to stop the flow on error

Answer

Reduce the timeout of the HTTP action

Question 12

A Power Pages site displays a list of support cases from a Dataverse 'Case' table. The requirement is that a case should only be visible to the user who created it. Which configuration should be used?

Accepted Answer

Entity permissions. Entity permissions with the 'Owner' access type restrict record-level operations (read, write, delete) to only the record owner. This configuration ensures that a case is only visible to the user who created it. Option D is incorrect because column-level permissions control visibility of individual columns, not rows; they cannot hide entire records. Page permissions (A) control access to pages, not records. Web roles (C) define user groups and permissions but do not enforce owner-based filtering.

Answer

Page permissions

Answer

Web roles

Answer

Column-level permissions

Question 13

Refer to the exhibit. A Power Pages site has the above site settings. What behavior will users experience?

Accepted Answer

Users can register but must use an external identity provider. The site settings show that local account registration is disabled (LocalLoginEnabled = false) but external login is enabled (ExternalLoginEnabled = true), allowing users to register only via an external identity provider. Option A is incorrect because local accounts are not allowed. Option B is incorrect because registration is enabled. Option C is incorrect because while Microsoft Entra ID is an external provider, the setting does not mandate its exclusive use; any configured external provider is acceptable.

Answer

Users can register with a local account

Answer

Users cannot register at all

Answer

Users must use Microsoft Entra ID to sign in

Question 14

A Power Pages site is experiencing slow load times for a page that displays a list of products from a Dataverse table. The page uses a Liquid template with a fetch query that retrieves all products without filtering. Which change would most improve performance?

Accepted Answer

Modify the fetch query in the Liquid template to include a filter, such as only active products.. Modifying the fetch query in the Liquid template to include a filter (e.g., only active products) reduces the amount of data retrieved from Dataverse, directly addressing the performance issue caused by fetching all products. Option A (CDN) improves delivery of static assets, not dynamic query results. Option B (page caching) may help if the data doesn't change often, but it doesn't fix the underlying inefficiency of the query. Option C (out-of-the-box list component) still retrieves all data unless configured with a filter, so it does not guarantee improvement.

Answer

Enable the content delivery network (CDN) for the site.

Answer

Adjust the page caching settings in the Power Pages admin center.

Answer

Replace the Liquid template with the out-of-the-box list component.

Question 15

A company wants to build a public-facing website where customers can view their order history and submit support requests without needing to log in. Which Power Pages feature should they use to allow anonymous access to specific pages?

Accepted Answer

Configure page permissions to allow Everyone (Anonymous users). Power Pages allows configuring page permissions to grant access to 'Everyone' including anonymous users, enabling public access to specific pages without login. Option B is wrong because setting the site to private mode restricts access to authenticated users only, not allowing anonymous access. Option C is wrong because Dataverse table permissions control data access within a table, not page-level access; they do not directly allow anonymous page viewing. Option D is wrong because Azure AD B2C is an identity provider for authentication, not for enabling anonymous access; it requires users to log in.

Answer

Set the site to private mode

Answer

Use Dataverse table permissions

Answer

Integrate Azure AD B2C for anonymous access
