Summary of Exam Objectives


Internet connectivity is an important consideration in most networks today. The first consideration when planning Internet connectivity is whether to use a routed connection or a translated connection to the Internet. A routed connection places all machines in the network on the Internet, and each requires an IP address. A translated connection uses a separate private addressing scheme on the local network, and a server translates between public and private IP addresses to provide shared Internet access. In Windows networks, translated connections typically use NAT or ICS, a simplified version of NAT supported by Windows systems.

A VPN is an extension of a private network using a public network, such as the Internet, functioning as a conduit between two points. There are two basic types of VPNs: Internet-based VPNs, used by clients for remote access, and router-to-router VPNs, used to connect two segments of a WAN. VPNs use a tunneling protocol (such as PPTP or L2TP) to encapsulate data, in conjunction with an encryption protocol (such as MPPE or IPSec) to encrypt it before sending it over the public network. RADIUS is an Internet standard for a server that provides centralized authentication, authorization, and accounting services. Microsoft IAS is an implementation of a RADIUS server. RADIUS allows you to centralize the authentication and auditing features of one or more RRAS servers. RRAS servers connect to the IAS server with authentication requests. The IAS server supports Remote Access Policies, which replace the individual policies normally stored at each RRAS server.

Windows operating systems can use the Connection Manager utility for creating connections to dial-up networks or VPNs. Windows Server 2003 includes CMAK, which lets you use a Wizard to customize Connection Manager for your particular connections. CMAK allows you to specify dial-up or VPN server information, authentication settings, and other options to create the connection. You can also specify custom icons, graphics, and a help file to personalize Connection Manager.
