You have an Azure Logic Apps Consumption workflow that uses a Request trigger.

A Logic Apps Request trigger can be invoked through different authorization mechanisms. If all supported methods are enabled but only OAuth-based requests should be accepted, disabling shared access signature authentication removes the non-OAuth shared-secret URL model. Secure Inputs and Secure Outputs protect run-history data but do not control request authentication. API Management could enforce auth but adds cost and complexity, which the requirement says to minimize. The exam objective emphasizes practical identity enforcement rather than cosmetic configuration. A valid answer must identify who authenticates, what permission is granted, where the scope is applied, and whether the method continues to work without passwords or secrets. That is why the selected answer is preferred over broader administrative roles or unrelated access settings. The result is a direct exam-style implementation choice: it changes the required security behavior without relying on unrelated monitoring, manual cleanup, or excessive privilege.
