The correct answer is the Azure AD B2C user flow for sign-up, because that is where you can add custom attributes and UI elements like a consent checkbox during registration. Azure AD B2C user flows allow you to collect additional information from users by defining custom attributes and then rendering them as form fields, including checkboxes, directly in the sign-up process. On the Microsoft Power Platform Fundamentals PL-900 exam, this question tests your understanding of where authentication customization occurs—specifically, that Power Pages relies on Azure AD B2C for identity management, not on Power Pages’ own limited interface. A common trap is confusing site settings or content snippets with functional form controls; remember that user flows handle interactive data collection, while content snippets only manage static text. Memory tip: “Flow for fields, snippets for text”—if you need a clickable checkbox, it belongs in the Azure AD B2C sign-up flow.

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
