Your company has an Active Directory Domain Services (AD DS) domain. All servers run Windows
Server 2008 R2. You are deploying Remote Desktop Services (RDS). You install a Remote Desktop
Session Host (RD Session Host) server in the environment. You need to install Remote Desktop
Services client access licenses (RDS CALs). What should you do first?

A.
Run the Install Licenses Wizard.

B.
Run the Manage RDS CALs Wizard.

C.
Add the Remote Desktop Licensing role service.

D.
Add the RD Session Host server to a new group in the Remote Desktop Connection Manager
console.

Explanation:
To use Remote Desktop Services, you must also have at least one license server deployed in your
environment. For small deployments, you can install both the RD Session Host role service and the
RD Licensing role service on the same computer. For larger deployments, it is recommended that the
RD Licensing role service be installed on a separate computer from the RD Session Host role service.
