Answer :
The default URL suffix for an Azure Active Directory (Azure AD) tenant is 'onmicrosoft.com'. When you create an Azure AD tenant, it is automatically assigned a domain that ends with 'onmicrosoft.com'. This domain is used as the default domain for your tenant. For example, if you create a tenant called 'example', the domain will be 'example.onmicrosoft.com'.
The DNS suffix for the tenant is also part of this default domain. It helps in identifying the tenant uniquely in the Azure ecosystem.
In the context of the given options, the correct answer is option 2: 'onmicrosoft.com'.
Understanding Azure AD is crucial since it's a cloud-based identity and access management service by Microsoft. It helps organizations manage users and applications securely. This service is commonly utilized in Office 365, Azure, and other Microsoft services that require authentication and authorization.
