Your network contains a single Active Directory domain. The domain contains two servers. The
servers are configured as shown in the following table.

Server2 is configured to use Server1 as a licensing server. You install 100 Remote Desktop Services
Per User client access licenses (RDS Per User CALs) on Server1. You discover that when users connect
to Remote Desktop Services (RDS) on Server2, they receive temporary licenses. You need to ensure
that users receive permanent licenses when they connect to Server2. What should you do?

A.
On Server2, install the RD Licensing role service.

B.
On Server2, change the Remote Desktop licensing mode to Per User.

C.
On Server1, remove the RD Session Host role service.

D.
On Server1, change the discovery scope of the license server to Domain.

Explanation:
When a Remote Desktop Session Host (RD Session Host) server is configured to use Per Device
licensing mode, and a client computer or device connects to an RD Session Host server for the first
time, the client computer or device is issued a temporary license by default. When a client computer
or device connects to an RD Session Host server for the second time, if the Remote Desktop license
server is activated and enough RDS Per Device CALs are available, the license server issues the client
computer or device a permanent RDS Per Device CAL. If the license server is not activated or does
not have any RDS Per Device CALs available, the device continues to use the temporary license. The
temporary license is valid for 90 days.
Because no Per Device CALs are available, we’ve got “100 Remote Desktop Services Per User client
access licenses (RDS Per User CALs)” on Server1, the device will never get its permanent Per Device
CAL.
