A. 7 Azure AD Pass-through Authentication and Seamless SSO can be installed on a maximum of 7 servers in your environment. These servers are known as Standalone Authentication Agents and are used to authenticate your on-premises users to Azure AD. These servers are installed on-premises and communicates with the Azure AD Pass-through Authentication service to authenticate the users to Azure AD. It is important to note that Azure AD Pass-through Authentication and Seamless SSO are different from Azure AD Connect, which is responsible for synchronizing your on-premises Active Directory with Azure Active Directory.
