You have an Azure Active Directory (Azure AD) tenant named contoso.com and an Azure virtual network named VNET1.
To VNET1, you deploy an Azure Active Directory Domain Services (Azure AD DS) managed domain named litwareinc.com.
To VNET1, you plan to deploy a Windows Virtual Desktop host pool named Pool1.
You need to ensure that you can deploy Windows 10 Enterprise host pools to Pool1.
What should you do first?
A . Modify the settings of the litwareinc.com DNS zone.
B . Modify the DNS settings of VNET1.
C . Add a custom domain name to contoso.com.
D . Implement Azure AD Connect cloud sync.
"Update DNS settings for the Azure virtual network With Azure AD DS successfully deployed, now configure the virtual network to allow other connected VMs and applications to use the managed domain. To provide this connectivity, update the DNS server settings for your virtual network to point to the two IP addresses where the managed domain is deployed."
