You need to configure WSRM to enforce Policy1

You manage a member server that runs Windows Server 2008 R2.
The server has the Remote Desktop Services server role installed.
Windows System Resource Manager (WSRM) is installed on the server.

Users report performance degradation on the Remote Desktop Session Host Server.
You monitor the server and notice that one user is consuming 100 percent of the processor time.
You create a resource-allocation policy named Policy1 that limits each user to 30 percent of the total processor time.
You observe no performance improvement.

You need to configure WSRM to enforce Policy1.

What should you do?

A.
Set Policy1 as the Profiling Policy.

B.
Set Policy1 as the Managing Policy.

C.
Restart the Remote Desktop Configuration service.

D.
Launch the WSRM application by using the user context of the Remote Desktop Session Host Server System account.

Explanation:
Resource-Allocation Policies
WSRM uses resource-allocation policies to determine how computer resources, such as CPU and memory, are allocated to processes running on the computer. There are two resource-allocation policies that are specifically designed for computers running Terminal Services. The two Terminal Services-specific resource-allocation policies are:
* Equal_Per_User
* Equal_Per_Session

To implement the Equal_Per_Session resource-allocation policy
Open the Windows System Resource Manager snap-in.
In the console tree, expand the Resource Allocation Policies node.
Right-click Equal_Per_Session, and then click Set as Managing Policy.
If a dialog box appears informing you that the calendar will be disabled, click OK.
