A company receives IoT telemetry data from devices via Azure Event Hubs. The data must be processed and stored in Dataverse. The volume is high and the processing must be near real-time. The company wants to use a serverless approach and minimize infrastructure management. What should you do?

Use an Azure Function with an Event Hubs trigger that writes to Dataverse using the SDK.

Use a custom API that the devices call directly to write to Dataverse.

Use a Power Automate cloud flow with an Event Hubs trigger.

Create a plug-in that listens to Event Hubs.

A company uses a third-party CRM system that exposes a REST API. The company wants to display data from this CRM inside a Power Apps canvas app. The API requires OAuth 2.0 authentication with client credentials. What should the developer create?

A custom API in Dataverse that proxies the external API.

A custom connector that uses the OAuth 2.0 authentication type.

A Power Automate cloud flow that calls the API and returns the data.

A code component (PCF) that makes the API call directly.

A company needs to send Dataverse data to an external system when a record is updated. The external system requires the data to be sent in a specific JSON format and the operation must be reliable, with retry logic. What should the developer implement?

A custom connector that is triggered on record update.

A Power Automate cloud flow triggered on record update that sends the data to the external system.

A plug-in that sends the data to the external system.

A client script that sends the data on form save.
