AZ-104: Configure Azure DNS Exam
Questions & Answers (Grade A+)
Initial domain name -
correct answer ✅When you create an Azure subscription, an Azure
AD domain is automatically created. This instance of the domain
has an initial domain name in the form
domainname.onmicrosoft.com. The initial domain name is
intended to be used until a custom domain name is verified.
Custom domain name -
correct answer ✅The initial domain name can't be changed or
deleted. You can however add a routable custom domain name you
control. A custom domain name simplifies the user sign-on
experience. Users can use credentials they are familiar with. For
example, a contosogold.onmicrosoft.com, could be assigned to
contosogold.com.
Practical information about domain names -
correct answer ✅You must be a global administrator to perform
domain management tasks. The global administrator is the user
who created the subscription.

Domain names in Azure AD are globally unique. When one Azure
AD directory has verified a domain name, other directories can't
use that name.
Before a custom domain name can be used by Azure AD, the
custom domain name must be added to your directory and verified.
Verify custom domain names -
correct answer ✅When an administrator adds a custom domain
name to an Azure AD, it is initially in an unverified state. Azure AD
won't allow any directory resources to use an unverified domain
name. Only one directory can use a domain name, the organization
that owns the domain name.
After adding the custom domain name, you must verify ownership
of the domain name. Verification is performed by adding a DNS
record. The DNS record can be MX or TXT. Once the DNS record is
added, Azure will query the DNS domain for the presence of the
record. This could take several minutes or several hours. When
Azure verifies the presence of the DNS record, it will then add the
domain name to the subscription.
