Your network contains an Active Directory domain.

You deploy a server named Server1 that has the Remote Desktop Connection Broker (RD Connection Broker) role service installed.

You need to ensure that all servers that have the Remote Desktop Session Host (RD Session Host) role service installed are automatically configured to use Server1 as an RD Connection Broker.

What should you do?

A.
Register a service principal name (SPN) for Server1.

B.
Register a service location (SRV) record for Server1.

C.
Use a Group Policy to configure the Restricted Groups settings.

D.
Use a Group Policy to configure the Remote Desktop Services settings.

Explanation:
RD Connection Broker
Policy settings in this node control configuration of a Remote Desktop Session Host server that is a member of a load-balanced Remote Desktop Session Host server farm.

The full path of this node in the Group Policy Management Console is
Computer Configuration\Policies\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\RD Connection Broker.

Available policy settings

* Join RD Connection Broker
This policy setting allows you to specify whether the RD Session Host server should join a farm in RD Connection Broker. RD Connection Broker tracks user sessions and allows a user to reconnect to their existing session in a load-balanced RD Session Host server farm. To participate in RD Connection Broker, the Remote Desktop Session Host role service must be installed on the server.
If the policy setting is enabled, the RD Session Host server joins the farm that is specified in the Configure RD Connection Broker Farm Name setting. The farm exists on the RD Connection Broker server that is specified in the Configure RD Connection Broker Server name policy setting.
If you disable this policy setting, the server does not join a farm in RD Connection Broker, and user session tracking is not performed. If the setting is disabled, you cannot use either the Remote Desktop Session Host Configuration tool or the Terminal Services WMI provider to join the server to RD Connection Broker.
If the policy setting is not configured, the setting is not specified at the Group Policy level. In this case, you can configure the server to join RD Connection Broker by using the Remote Desktop Session Host Configuration tool or the Terminal Services WMI provider.

If you enable this setting, you must also enable the “Configure RD Connection Broker Farm Name” and Configure RD Connection Broker Server name policy settings, or configure these settings by using either the Remote Desktop Session Host Configuration tool or the Terminal Services WMI provider.

* Configure RD Connection Broker farm name
This policy setting allows you to specify the name of a farm to join in RD Connection Broker. RD Connection Broker uses the farm name to determine which RD Session Host servers are in the same RD Session Host server farm. Therefore, you must use the same farm name for all RD Session Host servers in the same load-balanced farm. The farm name does not have to correspond to a name in Active Directory Domain Services.
If you specify a new farm name, a new farm is created in RD Connection Broker. If you specify an existing farm name, the server joins that farm in RD Connection Broker.
If you enable this policy setting, you must specify the name of a farm in RD Connection Broker.
If you disable or do not configure this policy setting, the farm name is not specified by Group Policy. In this case, you can adjust the farm name by using the Remote Desktop Session Host Configuration tool or the Terminal Services WMI provider.

This setting is not effective unless both the Join RD Connection Broker and the Configure RD Connection Broker server name settings are enabled and configured by using Group Policy, the Remote Desktop Session Host Configuration tool, or the Terminal Services WMI provider.

* Configure RD Connection Broker server name
This policy setting allows you to specify the RD Connection Broker server that the RD Session Host server uses to track and redirect user sessions for a load-balanced RD Session Host server farm. The specified server must be running the Remote Desktop Connection Broker service. All RD Session Host servers in a load-balanced farm should use the same RD Connection Broker server.
If you enable this policy setting, you must specify the RD Connection Broker server, using either its host name, IP address, or fully qualified domain name. If you specify a name or IP address for the RD Connection Broker server that is not valid, an error message is logged in Event Viewer on the RD Session Host server.
If you disable or do not configure this policy setting, you can adjust the RD Connection Broker server name or IP address by using the Remote Desktop Session Host Configuration tool or the Terminal Services WMI provider.

This policy setting is not effective unless the Join RD Connection Broker policy setting is enabled or the RD Session Host server is configured to join RD Connection Broker by using the Remote Desktop Session Host Configuration tool or the Terminal Services WMI provider.
To be an active member of an RD Connection Broker-enabled RD Session Host server farm, the computer account for each RD Session Host server in the farm must be a member of the Session Directory Computers local group on the RD Connection Broker server.

* Use RD Connection Broker load balancing
This policy setting allows you to specify whether to use the RD Connection Broker load balancing feature to balance the load between servers in an RD Session Host server farm.
If you enable this policy setting, RD Connection Broker redirects users who do not have an existing session to the RD Session Host server in the farm with the fewest sessions. Redirection behavior for users with existing sessions is not affected. If the server is configured to use RD Connection Broker, users who have an existing session are redirected to the RD Session Host server where their session exists.
If you disable this policy setting, users who do not have an existing session log on to the first RD Session Host server to which they connect.
If you do not configure this policy setting, you can configure the RD Session Host server to participate in RD Connection Broker load balancing by using the Remote Desktop Session Host Configuration tool or the Terminal Services WMI provider.

If you enable this policy setting, you must also enable the Join RD Connection Broker, the Configure RD Connection Broker farm name, and the Configure RD Connection Broker server name policy settings.
