Exam Professional Cloud Security Engineer topic 1 question 288 discussion

D is incorrect: the question specifically highlights the need for corporate users to access the application using their corporate user credentials, which is best addressed through Workforce Identity Federation.

"the application will have both corporate AND PUBLIC END-USERS". This means that the solution applies to Identity Platform, therefore D.

Obviously it's D. - Identity Platform : A customer identity and access management (CIAM) platform that lets users sign in to your applications and services. This is ideal for users who want to be their own identity provider, or who need the enterprise-ready functionality Identity Platform provides. - Workforce Identity Federation : This is an IAM feature that lets you configure and secure granular access for your workforce—employees and partners—by federating identities from an external identity provider (IdP).

B is correct - By federating your customers' IdP with WIF, you can provide a seamless authentication experience for your users while maintaining control over identity and access management in your Google Cloud environment.

I think it's B.
