1. Correct answer: C. private IP address because all private IP addresses begin with
192.168.
A is incorrect because this is not an example of a DNS server address although it could
be assigned to a DNS server that is only used on a private network, not an Internet DNS
name server.
B is incorrect because all IP addresses that begin with 192.168 are private IP addresses,
not public IP addresses.

8. Correct answer: D. NETSTAT is the command you use to view the status of current
connections, including the IP address and protocol used for each connection.
A is incorrect because IPCONFIG displays the IP configuration, not the current
connection status, including the IP address and protocol used for each connection.

the current connection status, including the IP address and protocol used for each
connection.
C is incorrect because PING is used to test connectivity between two hosts, not to display
the current connection status, including the IP address and protocol used for each
connection.
E is incorrect because TRACERT traces a route to a destination; it does not display the
current connection status, including the IP address and protocol used for each connection.
9. Correct answer: D. Server Message Block (SMB) is Microsoft’s original file and print
sharing protocol.

10. Correct answer: B. NSLOOKUP is the command to use to test to see if a DNS server will
respond to a request to resolve a name.
A is incorrect because PING is used to test for connectivity between two computers.
C is incorrect, because IPCONFIG is used to display the IP configuration of the network
adapters on a computer.
D is incorrect because NETSTAT displays the status of the network connections,
including current connections, IP address of the destination, and protocol used on each
connection.
E is incorrect because TRACERT tests the route to a destination.
11. Correct answer: B. Subnet mask is the IPv4 configuration setting that defines the two
parts of an IP address: the Host ID and the Net ID.
A is incorrect because the gateway is the address of the local router, not a setting that
defines the two parts on an IP address.
C is incorrect because DNS is the address of a DNS name server.
D is incorrect because DHCP is not, in itself an IP configuration setting.
E is incorrect because host name is not an IPv4 configuration setting that defines the two
parts of an IP address.
12. Correct answer: D. The Advanced Privacy Settings dialog box contains the settings for
managing cookies. It is accessed via the Advanced button on the Privacy page.

manages cookies.
13. Correct answer: C. Dial-up, because this should be the least expensive, and your neighbor
will not need a faster service just for e-mail.

usually more expensive than dial-up.
B is incorrect because your neighbor does not seem to need the speed of ISDN, which is
more expensive than dial-up.

Answers to Essay Quiz
Answers will vary, since some of the questions are looking for opinion, and all answers
are expected to be in the student's own words.
1.
To test connectivity of a new network connection on a computer that connects to the
Internet through a LAN I would first use the IPCONFIG (Windows) or ifconfig
(Linux or Mac OS X) command to discover the local IP address and default gateway
(router). Then I would PING the local address. If that were successful, I would PING
the router, and then PING a computer on the Internet. If I do not have an IP address of
a computer on the Internet, I would ping a FQDN, like www.google.com.
2.
I would use an FTP client program rather than a Web browser because the client
program would save the site information, username, and password, and I would not
have to enter them every time I needed to connect to the site.
3.
The best type of connection for the mobile units is a satellite data connection. The socalled ground station would consist of a dish attached to a special mount on the roof
of a vehicle. The mount allows for moving the dish to align on the satellite, thus the
dish can easily be repositioned every time the mobile unit moves to a new location.
4.
Homegroup, new in Windows 7, is an easy-to-configure implementation of
Microsoft’s file and print sharing, with only a single password protecting the
Homegroup shares on all Windows 7 computers that join a HomeGroup.
5.
A subnet mask is required for an IP address in order to define which part of the
address identifies the network (the Net ID) and which part of the address identifies
the host on the network (the Host ID).
