A. B. C. D.

C

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 "alice@contoso.com.' instead of 'alice@domain 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.

https://docs.microsoft.com/en-us/azure/active-directory/fundamentals/add-custom-domain

To support the planned infrastructure, you need to define a custom domain name for Azure AD. The domain name you choose should be unique, resolvable, and under your ownership.

Option A, ad.humongousinsurance.com, could be a valid option, but it is not recommended to use "ad" as a domain name, as it is commonly used for Active Directory. Moreover, it may cause issues with certain protocols, such as LDAP.

Option B, humongousinsurance.local, is not a recommended option for a custom domain name in Azure AD. The .local domain is reserved for Multicast DNS (mDNS) and is not routable on the internet. Therefore, it should not be used as a custom domain name.

Option C, humongousinsurance.com, is a recommended option for a custom domain name in Azure AD. It is a registered domain that is owned by Humongous Insurance and can be used to create a public domain in Azure AD. It is also a resolvable domain name that can be accessed from anywhere on the internet.

Option D, humongousinsurance.onmicrosoft.com, is the default domain name that Azure AD assigns to every new tenant. It can be used as a custom domain name, but it is not recommended since it does not reflect the company's branding and may cause confusion among users.

Therefore, the recommended domain name to use as a custom domain name for Azure AD in this case is option C, humongousinsurance.com.
