SC-900 Describe the capabilities of Microsoft Entra Practice Question

A company wants to allow its partners to access a specific SharePoint Online site using their own corporate credentials. The company does not want to manage partner accounts. Which Microsoft Entra feature should they use?

⚠ Common exam trap

It's easy for candidates to confuse Conditional Access (which controls access after authentication) with the identity provider federation capability of External ID, mistakenly thinking policies alone can enable external authentication without a dedicated identity solution.

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

Microsoft Entra External ID

Microsoft Entra External ID (formerly Azure AD B2B) allows organizations to grant external partners access to resources like SharePoint Online using their own corporate or social identities. This eliminates the need to create and manage separate user accounts for partners, as they authenticate through their home identity provider via federation or invitation redemption.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Microsoft Entra External ID

    Why this is correct

    Microsoft Entra External ID is the comprehensive solution for managing external identities and providing them secure access to your organization's applications and resources. It enables business-to-business (B2B) collaboration, allowing partners to use their existing corporate or social identities (e.g., Microsoft accounts, Google, federated SAML/WS-Fed providers) to sign in. This feature integrates external users directly into your Microsoft Entra tenant, facilitating seamless collaboration while maintaining administrative control over their access permissions.

  • Microsoft Entra Privileged Identity Management

    Why it's wrong here

    Microsoft Entra Privileged Identity Management (PIM) is designed to manage, control, and monitor access to important resources within an organization's own Microsoft Entra tenant. Its primary function is to provide just-in-time and just-enough access for privileged roles, reducing the risk associated with standing administrative permissions. PIM focuses exclusively on internal administrative roles and does not facilitate the initial provisioning or management of external user identities for general partner access.

  • Microsoft Entra Identity Protection

    Why it's wrong here

    Microsoft Entra Identity Protection is a security tool focused on detecting and remediating identity-based risks across an organization's users, including both employees and guests. It leverages machine learning to identify suspicious sign-in behaviors and compromised credentials, applying policies like requiring multi-factor authentication or blocking access. While it protects *all* identities, its core purpose is risk detection and response, not the initial establishment of external collaboration capabilities for partners.

  • Microsoft Entra Conditional Access

    Why it's wrong here

    Microsoft Entra Conditional Access allows organizations to enforce policies that evaluate specific conditions before granting access to resources. These policies can require multi-factor authentication, restrict access based on location, or mandate compliant devices for *existing* identities attempting to sign in. However, Conditional Access does not create or manage the external user accounts themselves; it only applies access controls to identities that have already been provisioned within the directory, including external users managed by External ID.
