Hot Area:

Suggested Answer:
Box 1: Azure AD B2C authentication
Ensures that customers can use their Facebook credentials to authenticate to an Azure App Service website.
You can set up sign-up and sign-in with a Facebook account using Azure Active Directory B2C.
Box 2: Azure AD B2B authentication with access package assignments
Govern access for external users in Azure AD entitlement management
Azure AD entitlement management uses Azure AD business-to-business (B2B) to share access so you can collaborate with people outside your organization.
With Azure AD B2B, external users authenticate to their home directory, but have a representation in your directory. The representation in your directory enables the user to be assigned access to your resources.
Incorrect:
Not: Password hash synchronization in Azure AD connect
The partners are not integrated with AD DS.
