1. Which of the following types of networks allows controlled access from outside parties to specific
information within an organization's secured network, such as allowing parents to view their child's
grades?
A. Router
B. Server
C. Intranet
D. Extranet
Correct Answer: D
Rationale: An extranet is a private network that uses Internet protocols and network connectivity to
securely share part of an organization's information or operations with external parties such as
parents, suppliers, or partners. A router is a physical networking device, a server stores data, and an
intranet is for internal organizational communications only.
2. While researching the origins of a community, a student discovers conflicting information among
sources. Which of the following sources is considered the MOST reliable for resolving this conflict?
A. An editorial commemorating the hundredth anniversary of the community's founding
B. Famous anecdotes in pamphlets distributed by the local chamber of commerce
C. Published letters written by one of the community's original settlers
D. A recent biography of the individual credited with founding the community

File-sharing copied movies violates copyright distribution rights. Using current music without
permission interferes with the copyright owner's rights to publicly perform or distribute the work.
4. According to copyright law and Fair Use guidelines for educational purposes, what approximate
percentage of a copyrighted song may be used without obtaining permission?
A. 10%
B. 25%
C. 50%
D. 0%

composition may be used for educational purposes without obtaining permission from the copyright
holder.
,5. Which TWO of the following activities are examples of using audio, video, or digital sources to solve

C. Summarizing electronic book information provided about the Amazon rain forest
D. Using an online archive of photographs to generate questions about life during the Great
Depression
E. Watching current travel videos of historical locations throughout the United States
Correct Answers: A and D
Rationale: Collecting and analyzing data to identify areas of critical need is research consistent with
authentic problem-solving. Generating questions from a digital archive also involves authentic inquiry.
Options B, C, and E involve summarizing, dramatizing, or watching content without the degree of
original thinking or research required for authentic problem-solving.
6. The system by which computers process information using only two states is called:
A. ASCII
B. Binary
C. Trinary
D. Digital Encoding
Correct Answer: B
Rationale: Computers operate using the binary system, which consists of only two states (0 and 1).
This is based on circuits that function like switches, allowing information to pass or not pass. ASCII is a
character encoding standard for text, not the fundamental operating system of computers.
7. The DNS (Domain Name System) performs which primary function on the Internet?
, A. Translates domain names into IP addresses
B. Provides security for Web transactions
C. Encrypts data during transmission
D. Assigns domain names to Web servers
Correct Answer: A
Rationale: The Domain Name System (DNS) is an Internet service that translates human-friendly
domain names into numerical IP addresses. Because domain names are alphabetic and easier to
remember, DNS performs the critical function of translating the name into the corresponding IP
address that the Internet uses for routing.
8. Which of the following BEST describes a LAN (Local Area Network)?
A. A network of devices in close physical proximity
B. A network that spans a large geographic area
C. A public network accessible to anyone
D. An internal network that uses World Wide Web standards
Correct Answer: A
Rationale: A Local Area Network (LAN) is a network of devices within a limited geographic area such
as a building or campus. WANs span larger geographic areas, the Internet is public, and an intranet is
an internal network using WWW standards.
9. Which of the following is NOT an accurate statement regarding the difference between the Internet
and an Intranet?
A. The Internet has various sources of information; an Intranet contains group-specific information
B. The Internet is public; an Intranet is open
