Lesson 4 Review
1. What is a HOSTS file, and when would you create one?
A HOSTS file is a manually maintained local file that provides host-to-IP address resolution. You
use a HOSTS file for networks without access to a DNS name server to provide host-to-IP
address and NetBIOS-to-IP name resolution for applications and services.
2. Which of the following functions do you perform by using the Advanced TCP/IP
Settings dialog box? (Choose all that apply.)
a. Edit the IP address of a DNS server.
b. Delete the IP address of a DNS server.
c. Enter additional IP addresses for other available DNS servers.
d. Edit the IP addresses of the DHCP servers on the network.
The correct answers are A, B, and C. D is not correct because you do not configure addresses
for DHCP servers by using the Advanced TCP/IP Settings dialog box.
3. What does selecting the Append These DNS Suffixes (In Order) option do?
This option allows you to specify a list of domains to try when there is a query for an unqualified
name. Queries are limited to the domains that you listed.
Case Scenario Exercise
1. Andrew’s notebook has a network adapter built-in. When he is at work, Andrew
will connect the notebook to the company network. The company uses a DHCP
server to provide IP addresses to computers on the network. How should you
configure Andrew’s computer to connect to the company network?
You should configure Andrew’s computer to obtain an IP address automatically. You can do this
by opening the Properties dialog box for the LAN connection, opening the Properties dialog box
for the TCP/IP protocol, and then selecting the Obtain IP Address Automatically option.
2. When Andrew is at home, he will connect his notebook computer to a digital subscriber
line (DSL) modem supplied by his ISP. The ISP has issued Andrew a static
IP address. How should you configure Andrew’s computer so that it will use the
static IP address when he is at home without interfering with the DHCP service on
the company network?
You should configure an alternate TCP/IP configuration on Andrew’s computer. To do this, you
must first make sure that his computer is configured to use automatic IP addressing as its primary
configuration method. You can do this by opening the Properties dialog box for the LAN
connection, opening the Properties dialog box for the TCP/IP protocol, and then selecting the
Obtain IP Address Automatically option. When Windows XP Professional is configured to obtain
an address automatically, an Alternate Configuration tab becomes available in the Internet Protocol
(TCP/IP) Properties dialog box. On this tab, select the User Configured option and enter
the appropriate IP address, subnet mask, default gateway, and DNS server addresses provided
by the ISP.
