Your network consists of a single Active Directory domain. The domain contains a server that runs

Windows Server 2008 R2 and that has the Remote Desktop Services server role installed.
The server has six custom applications installed. The custom applications are configured as RemoteApps.
You notice that when a user runs one of the applications, other users report that the server seems slow and that some applications become unresponsive.
You need to ensure that active user sessions receive equal access to system resources.

What should you do?

A.
Implement Remote Desktop Web Access.

B.
Implement Remote Desktop Connection Broker.

C.
Configure Performance Monitor.

D.
Implement Windows System Resource Manager.

Terminal Services and Windows System Resource Manager

Windows System Resource Manager (WSRM) on Windows Server 2008 allows you to control how CPU and memory resources are allocated to applications, services, and processes on the computer. Managing resources in this way improves system performance and reduces the chance that applications, services, or processes will take CPU or memory resources away from one another and slow down the performance of the computer. Managing resources also creates a more consistent and predictable experience for users of applications and services running on the computer.

You can use WSRM to manage multiple applications on a single computer or users on a computer on which Terminal Services is installed.

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
