For example, you can use Dataverse within Power Automate in these key ways:

Create a flow to import data, export data, or take action (such as sending a notification) when data changes.

Instead of creating an approval loop through email, create a flow that stores approval state in an entity, and then build a custom app in which users can approve or reject items.

Box 1: PreValidation

PreValidation: For the initial operation, this stage will occur before the main system operation.

This provides an opportunity to include logic to cancel the operation before the database transaction.

Box 2: Synchronous

Ideally, you should only cancel operations using synchronous plug-ins registered in the PreValidation stage.

Box 3: Pre Image

Box 4: throw ..

When you throw an InvalidPluginExecutionException exception within a synchronous plug-in an error dialog with your message will be displayed to the user.

Correct Answer:

Box 1: OAuth 2.0 Use API keys if you expect developers to build internal applications that don't need to access more than a single user's data. Use OAuth access tokens if you want users to easily provide authorization to applications without needing to share private data or dig through developer documentation.

Requirements. Driving record verification

1.

Driving record verification must only be performed once for each candidate.

2.

Information required for driving record verification must be sent to the driving record verification service automatically after the candidate's address is verified.

3.

The API must return a value of either Approved or Rejected to indicate whether the candidate has met the company's requirements.

Box 2: Pass Credentials as parameters

User makes an API call with the authorization header and the token gets validated by using validate-jwt policy in APIM by Azure AD.

Note, see step 4 below.

In this Diagram we can see the OAUTH flow with API Management in which:

1.

The Developer Portal requests a token from Azure AD using app registration client id and client secret.

2.

In the second step, the user is challenged to prove their identity by supplying User Credentials.

3.

After successful validation, Azure AD issues the access/refresh token.

4.

User makes an API call with the authorization header and the token gets validated by using validate-jwt policy in APIM by Azure AD.

5.

Based on the validation result, the user will receive the response in the developer portal.

Correct Answer:

Box 1: Environment Maker

UserA must be able to create and publish Power Apps apps.

The Environment Maker role can create resources within an environment including apps,connections, custom connectors, gateways, and flows using Power Automate.

Box 2: System Administrator

UserB must be the owner of all the systems and be able to provide permissions and create all new environments.

The System Administrator has full permission to customize the system. Can view all data in the system.

Box 3: System Customizer

UserC must be able to create apps connected to the systems and update the security roles and entities.

The System Customizer has full permission to customize the system. Can only view rows for system tables that they create.

The difference between the System Administrator and System Customizer security roles is that a system administrator has read privileges on most rows in the system and can see everything. Assign the System Customizer role to someone

who needs to perform customization tasks but shouldn't see any data in the system tables.

Box 4: Common Data Service User

To stay consistent with our product rebranding effort, the security role Common Data Service User is being changed to Basic User.

The Basic User security role primarily contains Basic privileges for core entities where the user can write, update, and delete records that they created or owned.
