SC-900 Describe the capabilities of Microsoft Entra Practice Question
This SC-900 practice question tests your understanding of describe the capabilities of microsoft entra. 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 is using Microsoft Entra ID. You want to provide a single sign-on (SSO) experience for users accessing multiple SaaS applications. Which feature should you implement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Entra ID as an identity provider
Microsoft Entra ID acts as an identity provider (IdP) to enable single sign-on (SSO) for SaaS applications. When configured as the IdP, Entra ID authenticates the user once and issues a security token (e.g., SAML 2.0 assertion or OpenID Connect token) that is accepted by the SaaS application, eliminating the need for repeated logins. This is the core mechanism for federated SSO across multiple cloud applications.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✓
Microsoft Entra ID as an identity provider
Why this is correct
Microsoft Entra ID supports federated SSO with many SaaS apps.

✗
Microsoft Entra application proxy
Why it's wrong here
Application proxy publishes on-premises apps externally, not SSO for SaaS.
✗
Microsoft Entra myapps portal
Why it's wrong here
The myapps portal is a user portal to launch apps, but SSO is provided by the identity provider.
✗
Microsoft Entra Privileged Identity Management
Why it's wrong here
PIM manages privileged access, not SSO.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the My Apps portal (a user interface for launching apps) with the actual SSO authentication mechanism, but the portal itself does not perform authentication—it relies on Entra ID as the identity provider.
Detailed technical explanation
How to think about this question
Under the hood, Entra ID as an IdP supports multiple SSO protocols including SAML 2.0, OpenID Connect, and OAuth 2.0. When a user attempts to access a SaaS app, the app redirects the user to Entra ID's authorization endpoint; after successful authentication, Entra ID issues a signed token containing claims about the user, which the app validates using a pre-configured trust relationship. In real-world scenarios, this allows organizations to enforce conditional access policies (e.g., MFA) centrally during the SSO flow, even for third-party SaaS apps.

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.
