Question 1

Which Azure resource enables Power Platform to call an on-premises SOAP web service without exposing it to the public internet?

Accepted Answer

On-premises data gateway with custom connector

Answer

The on-premises data gateway paired with a custom connector securely tunnels calls to internal SOAP services without requiring inbound firewall rules.

Question 2

When implementing event-driven integration from Dataverse to an external system, which feature publishes Dataverse events to Azure Service Bus or Event Hub?

Accepted Answer

Service endpoint (service endpoint registration)

Answer

A Dataverse service endpoint registration configures the platform to push entity events directly to Azure Service Bus, Event Hub, or Event Grid.

Question 3

What is the maximum timeout for a synchronous HTTP response in a Power Automate flow triggered by 'When an HTTP request is received'?

Accepted Answer

30 seconds

Answer

The synchronous response to an HTTP trigger must be sent within 30 seconds; otherwise the caller receives a 202 Accepted and must poll for results.

Question 4

In Power Platform ALM, which solution component type stores the credentials configuration for a connector used inside a cloud flow?

Accepted Answer

Connection reference

Answer

Connection references are solution-aware components that hold the connector type and allow swapping the underlying connection per environment during deployment.

Question 5

A developer registers a plug-in step in Dataverse for the 'Create' message on the Account table. In which pipeline stage should they register it to validate data BEFORE it is written to the database?

Accepted Answer

Pre-operation

Answer

The pre-operation stage fires after security checks but before the database write, making it the correct stage to modify or validate input data.
