Microsoft Azure Fundamentals AZ-900 Practice Question

Azure Active Directory Business-to-Business (B2B) collaboration allows organizations to invite external users to access their resources using the external users’ own work, school, or other organizational accounts. This eliminates the need to create and manage new accounts for external users in your directory.

Azure AD B2C is designed for customer-facing applications where users sign up using their personal identities (e.g., social media accounts), not for partner organizations' users.

Azure AD Domain Services provides managed domain services but does not facilitate external collaboration.

Azure Multi-Factor Authentication (MFA) enhances security but does not address the requirement to allow external users to use their existing accounts.
