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 company wants to provide a single sign-on experience for all cloud applications. Which Microsoft Entra ID feature should you implement?
B2B collaboration
Why wrong: B2B is for inviting external users, not SSO.
Identity Protection
Why wrong: Identity Protection detects risks, not SSO.
App registration and SSO configuration
App registration allows apps to use Entra ID for authentication, enabling SSO.
Conditional Access
Why wrong: Conditional Access enforces access policies, not SSO.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
App registration and SSO configuration
App registration and SSO configuration in Microsoft Entra ID enables single sign-on (SSO) by registering each cloud application as an enterprise application and configuring federation protocols such as SAML 2.0, OpenID Connect, or OAuth 2.0. This allows users to authenticate once with their Entra ID credentials and access all configured cloud applications without repeated logins.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
B2B collaboration
Why it's wrong here
B2B is for inviting external users, not SSO.
Identity Protection
Why it's wrong here
Identity Protection detects risks, not SSO.
App registration and SSO configuration
Why this is correct
App registration allows apps to use Entra ID for authentication, enabling SSO.

Conditional Access
Why it's wrong here
Conditional Access enforces access policies, not SSO.
Common exam traps
The trap here is that candidates often confuse Conditional Access (a policy enforcement tool) with SSO configuration, or they mistakenly think B2B collaboration is needed for internal app SSO, when in fact App registration and SSO configuration is the correct feature for enabling a unified sign-on experience.
Detailed technical explanation
Under the hood, App registration creates a service principal in the tenant, and SSO configuration involves setting up the OAuth 2.0 authorization code flow or SAML 2.0 assertions. A subtle behavior is that SSO relies on the user's primary refresh token (PRT) issued by Entra ID, which is cached on the device and used to silently acquire access tokens for registered apps. In a real-world scenario, a company using Salesforce, ServiceNow, and Office 365 can register each app and configure SAML-based SSO so users authenticate once via the Microsoft login page.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
