Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
External Identities (social identity providers)
Option D is correct because External Identities (social identity providers) in Microsoft Entra ID allows you to configure Google and Facebook as identity providers for external users. This enables partners to sign in using their existing social accounts without needing a separate Microsoft account, leveraging OAuth 2.0 and OpenID Connect protocols for authentication.
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 that candidates often confuse Microsoft Entra B2B collaboration (which handles external organizational accounts) with External Identities (which includes social identity providers), leading them to incorrectly select B2B when the question explicitly mentions Google or Facebook accounts.
Detailed technical explanation
How to think about this question
Under the hood, External Identities (social identity providers) in Microsoft Entra ID uses the SAML or OpenID Connect protocol to federate with Google and Facebook, allowing token exchange without creating a new identity in the tenant. A subtle behavior is that while B2B collaboration can technically be extended with custom policies to support social IdPs, the native 'External Identities' feature is the direct, out-of-the-box method for enabling Google and Facebook sign-in for partners. In a real-world scenario, a company might use this to allow contractors to access a resource portal using their personal Gmail accounts, avoiding the need to manage guest accounts manually.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
