SC-900 Practice Question: Describe the capabilities of Microsoft security solutions
This SC-900 practice question tests your understanding of describe the capabilities of microsoft security solutions. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Your organization uses Microsoft Entra ID for identity management. You need to implement a solution that allows users to sign in using their social media accounts, such as Google or Facebook. What should you configure?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
External identities (B2B) with social identity providers
Option C is correct because External identities (B2B) in Microsoft Entra ID allow you to configure social identity providers (e.g., Google, Facebook) as federation sources. This enables users to sign in with their existing social accounts by leveraging OAuth 2.0 and OpenID Connect protocols, without needing to create a separate Microsoft account.
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 confuse 'External identities (B2B) with social identity providers' with 'B2C' or think that passwordless methods like Authenticator can be used to bring in external social users, when in fact Authenticator only works for users already in the Entra ID tenant.
Detailed technical explanation
How to think about this question
When you add a social identity provider in Entra ID External Identities, you configure the provider's client ID and client secret from the social platform's developer console. The B2B collaboration flow uses the SAML or WS-Federation protocol for enterprise providers, but for social providers like Google, it relies on OpenID Connect (OIDC) to issue tokens that Entra ID validates. A real-world scenario is a consumer-facing app where users prefer to sign in with their Google account, reducing friction and eliminating the need for a separate username/password.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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.
