You need to define a custom domain name for Azure AD to support the planned infrastructure.
Which domain name should you use?
A . Join the client computers in the Miami office to Azure A
C . Add http://autologon.microsoftazuread-sso.com to the intranet zone of each client computer in the Miami office.
D . Allow inbound TCP port 8080 to the domain controllers in the Miami office.
E . Install Azure AD Connect on a server in the Miami office and enable Pass-through Authentication
F . Install the Active Directory Federation Services (AD FS) role on a domain controller in the Miami office.
Every Azure AD directory comes with an initial domain name in the form of domainname.onmicrosoft.com. The initial domain name cannot be changed or deleted, but you can add your corporate domain name to Azure AD as well. For example, your organization probably has other domain names used to do business and users who sign in using your corporate domain name. Adding custom domain names to Azure AD allows you to assign user names in the directory that are familiar to your users, such as ‘[email protected]’ instead of ‘[email protected] name.onmicrosoft.com’.
Scenario: Network Infrastructure: Each office has a local data center that contains all the servers for that office. Each office has a dedicated connection to the Internet.
Humongous Insurance has a single-domain Active Directory forest named humongousinsurance.com
Planned Azure AD Infrastructure: The on-premises Active Directory domain will be synchronized to Azure AD.
