Your network contains an Active Directory domain named contoso.com.
The domain contains a server named Server1 that runs Windows Server 2012 R2.
Server1 has the Active Directory Rights Management Services server role installed.
Your company works with a partner organization that does not have its own Active Directory Rights
Management Services (AD RMS) implementation.
You need to create a trust policy for the partner organization.
The solution must meet the following requirements:
– Grant users in the partner organization access to protected content.
– Provide users in the partner organization with the ability to create
protected content.
Which type of trust policy should you create?

A.
a federated trust

B.
Windows Live ID

C.
a trusted publishing domain

D.
a trusted user domain

Explanation:
In AD RMS rights can be assigned to users who have a federated trust with Active Directory
Federation Services (AD FS). This enables an organization to share access to rights-protected
content with another organization without having to establish a separate Active Directory trust or
Active Directory Rights Management Services (AD RMS) infrastructure.
Incorrect:
Not
C)
Trusted publishing domains allow one AD RMS server to issue use licenses that correspond
with a publishing license issued by another AD RMS server, but in this scenario the partner
organization does not have any Active Directory. Not
D)
A trusted user domain, often referred as a TUD, is a trust between AD RMS clusters, but in
this scenario the partner organization does not have any Active Directory.
