Your network contains two Active Directory forests named contoso.com and adatum.com. Each forest contains an Active Directory Rights Management Services
(AD RMS) root cluster. All servers run Windows Server 2012 R2.
You need to ensure that the rights account certificates issued in adatum.com are accepted by the AD RMS root cluster in contoso.com.

Suggested Answer:
A trusted user domain, often referred as a TUD, is a trust between AD RMS clusters that instructs a licensing server to accept rights account certificates (the certificates identifying users) from another AD RMS server in a different Active Directory forest.
