Lesson 3 Review<br />

1. Which two modes of networking are available for connecting to a wireless network<br />

in Windows XP Professional?<br />

Ad-hoc wireless networking, in which there are multiple stations but no AP, and infrastructure<br />

wireless networking, in which stations connect to an AP.<br />

2. What are four ways to protect a wireless network?<br />

MAC address filtering, disabling SSID broadcasting, using WEP encryption, and using WPA<br />

encryption.<br />

3. When you configure 802.1x authentication for wireless networking in Windows<br />

XP Professional, all wireless connections use the same authentication settings.<br />

(True/False)<br />

False. Windows XP Professional allows you to configure 802.1x authentication on a per-connection<br />

basis.<br />

Lesson 4 Review<br />

1. A user has set up ICS on a host computer that runs Windows XP Professional, but<br />

is experiencing problems with clients being able to connect to both the Internet<br />

and other computers on the network. Which of the following items could be the<br />

cause of the problems? Choose all that apply.<br />

a. There is a DHCP server on the network.<br />

b. There is a DNS server on the network.<br />

c. There are computers on the network with static IP addresses.<br />

d. There is a Windows 2000 server on the network.<br />

A, B, and C are correct. DHCP and DNS servers as well as computers with static IP addresses<br />

all cause problems for ICS. D is not correct because Windows 2000 servers can be members<br />

of workgroups and work with ICS as long as they are not also domain controllers that provide<br />

DHCP or DNS services.<br />

2. What IP address is assigned to the ICS host?<br />

192.168.0.1<br />

3. After enabling ICS on the host computer, how should you configure other computers<br />

in the workgroup to connect to the Internet through the ICS computer?<br />

You should configure other computers to obtain an IP address automatically. The ICS host acts<br />

as DHCP server, assigning IP addresses in the range 192.168.0.2 through 192.168.0.254 to<br />

other computers on the network.
