A company is building a Power Apps solution that uses a custom API. The API is called from both a canvas app and a Power Automate flow. The canvas app uses the signed-in user's Azure AD token. The flow runs in the context of the user who triggers it. The API must authorize based on the user's role in Dataverse. What is the best way to pass the user's identity to the API?

Embed the user's Dataverse role in the app and pass it as a custom header.

Use the Azure AD token from the canvas app and the flow's 'HTTP with Azure AD' action to call the API.

Use a service principal for both the canvas app and the flow.

Use an API key that is shared between the app and the flow.

When designing the authentication strategy for a Power Platform solution that includes a custom connector, which aspect should be considered?

The data source's physical location

The number of actions in the custom connector

The color scheme of the custom connector's icon

The authentication type supported by the external service

A company needs to store and query large volumes of time-series data from manufacturing sensors. The data is used for real-time dashboards and historical analysis. The company is using Dataverse and wants to minimize cost while maintaining performance. What should you recommend?

Use standard Dataverse tables with partitioning by date.

Use a custom connector to write to an external time-series database.

Store the data in Azure Data Lake and use a virtual table to query it.

Use elastic tables in Dataverse for the sensor data.
