Question 1

Which Microsoft Graph API permission scope is required for a Power Platform custom connector to read all users' calendars in an organization?

Accepted Answer

Calendars.Read (application)

Answer

Application permission Calendars.Read allows the connector to read all users' calendars without a signed-in user context, requiring admin consent.

Question 2

A Power Apps model-driven app requires real-time data from an external REST API. Which approach avoids storing data in Dataverse while still displaying it in the app?

Accepted Answer

Use a virtual table with a custom virtual table provider

Answer

Virtual tables (virtual entities) surface external data directly in model-driven apps by delegating CRUD operations to a custom provider at query time.

Question 3

What is the correct way to pass a Bearer token to a downstream API inside a Power Automate HTTP action?

Accepted Answer

Set the Authorization header to 'Bearer {token}'

Answer

The HTTP standard requires Bearer tokens to be sent in the Authorization header with the 'Bearer ' prefix.

Question 4

Which Power Automate action lets you iterate over paged OData responses from Dataverse when the result set exceeds 5,000 rows?

Accepted Answer

Do until loop checking @odata.nextLink

Answer

OData paged responses include an @odata.nextLink property; a Do Until loop that follows this link until it is empty retrieves all rows beyond the 5,000-row page limit.

Question 5

In the context of Power Platform integration, what is the role of Azure API Management (APIM) when fronting backend services?

Accepted Answer

It provides policy enforcement, rate limiting, and a stable URL for custom connectors to call

Answer

APIM acts as a façade that applies policies (throttling, auth, transformation) and exposes a consistent endpoint, which custom connectors target instead of backend services directly.
