You are working as a network administrator at ABC.com. The ABC.com network consists of a
single Active Directory domain named ABC.com. ABC.com has its headquarters in Chicago and
has branch offices all over the country. All servers on the ABC.com network run Windows Server
2003 and all client computers run Windows XP Professional.
A new ABC.com directive states that the branch offices should be able to connect to the Chicago
headquarters using VPN connections over the internet.
The Routing and Remote Access service has been enabled and configured on a Windows 2003
Server in each branch office. You are in the process of configuring four Windows 2003 servers in
the Chicago office to handle the VPN connections from the branch offices.
To enable centralized authentication and remote access policy management, you have installed
the Internet Authentication Service on a server named ABC-IAS1.
Which three of the following steps should you perform to complete the configuration?

A.
You should have ABC-IAS1 configured with the remote access policies.

B.
You should have the Routing and Remote Access servers in the Chicago office configured with
the remote access polices.

C.
Set up the RADIUS clients located at the branch offices on ABC-IAS1.

D.
Set up the RADIUS clients in the Chicago office on ABC-IAS1.

E.
Set up the Routing and Remote Access servers at the branch offices to utilize RADIUS
authentication and accounting.

F.
Set up the Routing and Remote Access servers in the Chicago office to utilize Windows
authentication and accounting.

G.
Set up the Routing and Remote Access servers in the Chicago office to utilize RADIUS
authentication and accounting.

H.
Configure the Routing and Remote Access servers at the branch offices to utilize Windows
authentication and accounting.

Explanation:
Internet Authentication Service (IAS) is the Microsoft implementation of Remote
Authentication Dial-In User Service (RADIUS), an authentication and accounting system used by
many Internet Service Providers (ISPs). When a user connects to an ISP using a username and
password, the information is passed to a RADIUS server, which checks that the information is
correct, and then authorizes access to the ISP system.
RADIUS proxy and server support is a new feature in Windows Server 2003. You can install and
use the Microsoft Internet Authentication Service (IAS) server for both RADIUS servers and
RADIUS proxies.
