Chapter 12 Practice Test Answers
1. C. Typically, a modem is used to dial into a remote access server.
2. A. Once dial-up users are authenticated, they may or may not be required to log
on a second time through the appropriate network client.
3. C. The multiprotocol routing component enables the server to act as a static
router.
4. A. The Internet connection server setting allows you to establish Network
Address Translation (NAT) services using this server.
5. B and E. If you want to use DHCP to assign IP addressing information
automatically, select the Automatically option. If you choose From a specified
range of addresses, you will be presented with another dialog box that will allow
you to enter the IP addressing information manually.
6. B. RADIUS adds security and accounting features to the RRAS server by
monitoring clients that try to connect to the server, by authenticating their
requests allowing them access to the server, and by providing enough
configuration information to the client so that the client can take advantage of
RRAS and network services.
7. D. To set up a basic RRAS server, open the Control Panel and locate the Network
and Dial-up Connections icon.
8. C. Any transaction that occurs between client and the RADIUS server is
authenticated by a shared secret.
9. A. The General properties dialog box allows you to decide whether the RRAS
server will also function as a router or just as a remote access server. If you place
a check mark in the Router option, a client will be able to dial up the RRAS server
and, after being properly authenticated, access resources on other servers and
computers on the network.
10. D. Multilink allows you to connect multiple adapters to multiple lines to take
advantage of the bandwidth of more than one line.
11. A. One ISDN adapter can act as more than one device because ISDN includes two
64-Kbps B channels. Each of these channels can be used independently,
essentially creating two separate physical devices. A multilink connection can be
used to combine multiple ISDN B channels of a basic rate interface (BRI)
connection.
12. B and C. You may also choose to use Bandwidth Allocation Protocol (BAP) and
Bandwidth Allocation Control Protocol (BACP) to allow for dynamic control of
the multilink bandwidth.
13. C. PPP provides error-checking features that SLIP does not have, and PPP has the
ability to share a data line.
14. D. The Point-to-Point Tunneling Protocol (PPTP) was designed as a more secure
way of transmitting messages across the Internet. PPTP is commonly used to
create virtual private networks (VPNs).
15. D. Independent Computing Architecture (ICA) is a Presentation layer protocol
that allows any Microsoft Windows client to act as a thin client. That means that
the client computer, even though is has a hard drive and its own processing
power, connects to a central server, which actually runs the application.
16. A. When an authentication failure occurs, always ensure you are typing the
correct user name and password.
17. B. Handshaking is the process of the client and server agreeing on the parameters
they will use to communicate. If you do not hear any of this happening, you most
likely have a physical connection problem, or you may be dialing the wrong
number.
18. C. Since one of the primary uses of RRAS is to enable Internet connectivity, all
RRAS servers will generally use the TCP/IP protocol. Therefore, the TCP/IP
protocol must be installed on the client computer. You may or may not be
required to manually configure your TCP/IP addressing parameters.
