Common exam trap: answer the scenario, not the keyword

Detailed technical explanation
How to think about this question
Microsoft Entra B2B collaboration uses the SAML 2.0 or WS-Federation protocol for federation with external Azure AD tenants, and it supports redemption via email OTP for users without Azure AD or Microsoft accounts. Under the hood, the invitation process creates a guest user object in the resource tenant's Azure AD, and the external user authenticates against their home tenant, with claims passed via the SAML token. A real-world scenario is a company inviting a partner's employees to access a SharePoint site; the partner users sign in with their own corporate credentials, and the resource tenant enforces conditional access policies based on the partner's tenant ID.

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.
