Your company has a load-balanced remote Desktop Session Host (RD Session Host)
cluster. You are configuring the Remote Desktop Gateway (RD Gateway) role service on
servers that run Windows Server 2008 R2. You need to centralize the storage of Remote
Desktop connection authorization policies (RD CAPs). Which two actions should you
perform? (Each correct answer presents part of the solution. Choose two.)

A.
Configure the RD Gateway servers to use a remote RD CAP store.

B.
Configure the RD Gateway servers to use a local RD CAP store.

C.
Install the Distributed File System role service.

D.
Install the Network Policy Server role service.

Explanation:
Network Policy Server (NPS) is the Microsoft implementation of a Remote Authentication
Dial-in User Service (RADIUS) server and proxy in Windows Server 2008. NPS is the
replacement for Internet Authentication Service (IAS) in Windows Server 2003.
As a RADIUS server, NPS performs centralized connection authentication, authorization,
and accounting for many types of network access, including wireless and virtual private
network (VPN) connections. As a RADIUS proxy, NPS forwards authentication and
accounting messages to other RADIUS servers. NPS also acts as a health evaluation server
for Network Access Protection (NAP).
Distributed File System (DFS) Namespaces and DFS Replication offer simplified, highlyavailable access to files, load sharing, and WAN-friendly replication. In the Windows
Server® 2003 R2 operating system, Microsoft revised and renamed DFS Namespaces
(formerly called DFS), replaced the Distributed File System snap-in with the DFS
Management snap-in, and introduced the new DFS Replication feature. In the Windows
Server® 2008 operating system, Microsoft added the Windows Server 2008 mode of
domain-based namespaces and added a number of usability and performance
improvements.
What does Distributed File System (DFS) do?
The Distributed File System (DFS) technologies offer wide area network (WAN)-friendly
replication as well as simplified, highly-available access to geographically dispersed files.
The two technologies in DFS are the following:
DFS Namespaces. Enables you to group shared folders that are located on different servers
into one or more logically structured namespaces. Each namespace appears to users as a
single shared folder with a series of subfolders. This structure increases availability and
automatically connects users to shared folders in the same Active Directory Domain
Services site, when available, instead of routing them over WAN connections. DFS
Replication. DFS Replication is an efficient, multiple-master replication engine that you can
use to keep folders synchronized between servers across limited bandwidth network
connections. It replaces the File Replication Service (FRS) as the replication engine for DFS

Namespaces, as well as for replicating the AD DS SYSVOL folder in domains that use the
Windows Server 2008 domain functional level.
