Correct answer & explanation
✓
Configure Microsoft Entra External ID with social identity providers.
Option D is correct because Microsoft Entra External ID (formerly Azure AD External Identities) allows you to configure social identity providers such as Google and Facebook as external identity sources. This enables users to sign in with their existing social media accounts while still being subject to your tenant's conditional access policies, ensuring security and compliance.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing Microsoft Entra B2B collaboration (for business guest users) with Microsoft Entra External ID (which includes social identity providers for consumer-facing apps), leading candidates to incorrectly select option C.
Detailed technical explanation
How to think about this question
Under the hood, Microsoft Entra External ID uses OAuth 2.0 and OpenID Connect protocols to federate with social identity providers. When configured, the user is redirected to the social provider's authorization endpoint (e.g., Google's OAuth 2.0 endpoint), and upon successful authentication, an ID token is returned to Entra ID, which then issues its own token for the application. This federation allows conditional access policies to evaluate the sign-in risk and enforce controls like MFA or device compliance, even though the user authenticates externally.

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.
