The communication department for a company plans to add a publicly accessible survey page to the company's public website.
You must add the new survey page to the company's public website and capture data from the page to a Common Data Service environment.
Explicit user credentials must not be required to write survey data to Common Data Service.
You need to implement authentication.
Which authentication mechanism should you implement?

A. ADFS

B. Azure AD Conditional Access

C. OAuth 2.0

D. Client secret








 

Suggested Answer: C

The OAuth 2.0 client credentials grant flow permits a web service (confidential client) to use its own credentials, instead of impersonating a user, to authenticate when calling another web service.
Note: OAuth is the preferred means to authenticate because it provides access to both the OData RESTful web services (Web API and OData global Discovery service) as well as to the SOAP web services (Organization service and Discovery service).
OAuth is also required to support:
✑ Azure Active Directory configurations for conditional access, such as Two-factor Authentication (2FA)
✑ Use of client secrets to enable server-to-server authentication scenarios.
✑ Cross-Origin Resource Sharing (CORS) to connect a Single-page Application (SPA)
