A company wants to create a custom connector for an Azure service that uses Azure Active Directory (Azure AD) authentication. The service exposes a REST API that requires an access token. The connector will be used in Power Automate flows. What should you configure for authentication?

Use Windows Authentication with the Azure AD credentials.

Use Basic authentication with the Azure AD username and password.

Use OAuth 2.0 with Azure AD as the identity provider and provide the tenant ID, client ID, and client secret.

Use API Key authentication and provide the Azure AD token as the key.

In the custom connector authentication configuration, what is the purpose of specifying a 'Resource' or 'Audience' parameter in an OAuth 2.0 setup?

To set the expiration time of the access token

To identify the API or service that the access token is intended for

To specify the client secret used to authenticate the connector

To define the redirect URI for the authorization code flow

A custom connector uses OAuth 2.0 with Azure AD. The API requires a token that includes a custom claim. The claim is not included in the default token. You need to ensure the token includes the claim. What should you do?

Use an Azure Function to modify the token before sending it to the API.

Use a policy template to add the claim to the Authorization header.

Configure the app registration in Azure AD to include the custom claim in the token.

Configure the API to accept the claim without modifying the connector.
