A company has a single Active Directory Domain Services (AD DS) domain and a single Remote Desktop Session Host (RD Session Host). The RD Session Host is approaching full memory capacity. All servers run Windows Server 2008 R2.

You are designing a Remote Desktop Services (RDS) infrastructure. The infrastructure must meet the following requirements:

– Allow infrastructure capacity to increase.
– Minimize the number of physical servers.
– Do not require administrative action on the client computers if the infrastructure capacity increases.

You need to design an RDS infrastructure that meets the requirements.

What should you recommend? (More than one answer choice may achieve the goal. Select the BEST answer.)

A.
Migrate the RD Session Host to a virtual machine (VM) running in Microsoft Hyper-V. Add memory to the VM as demand increases.

B.
Add RD Session Hosts as demand increases, and use Group Policy to direct users to the correct server.

C.
Install and configure Windows Server Resource Manager (WSRM) on the RD Session Host to control user resource allocation.

D.
Implement an RD Session Host server farm and add servers as required.

Explanation:

Virtualization meets the requirements easily enough, as capacity needs grow the VMs can be migrated to more powerful physical servers, again virtualization reduces the number of physical servers and finally as the actual RD Session Host wont change regardless of the location of that VM it will meet the third requirement

Ans D does not meet the 3rd requirement
Ans C wont resolve the problem of running out of memory only that addition of RAM will resolve that issue
Ans B again does not meet the 3rd requirement
