miles or a 1 GB Ethernet connection across the room? Choose all that apply.
■ A. Transport
✓ B. Network
✓ C. Application
■ D. Session
Rationale:
Network and Application layers are unaware if data is traveling over a WAN connection across thousands of miles
or over a 1 GB Ethernet connection across the room.
Multiple Response (select all that apply)
Q3. What type of devices are likely to be used in WANs for media access, signal transmissions and
reception, and connections, and connecting a WAN to a LAN? Choose all that apply.
✓ A. modems
✓ B. channel service units/data service units
■ C. switches
✓ D. routers
■ E. hubs
Rationale:
Several types of devices are commonly used in WANs for media access, signal transmission and reception, and for
connecting a WAN to a LAN and include modems, channel service units/data service units, and routers.
Multiple Choice
Q4. How are cable Internet and DSL signals transmitted?
■ A. digital carrier waves
✓ B. analog carrier waves
■ C. modulating carrier waves
■ D. demodulating carrier waves
Rationale:
Even though cable Internet and DSL signals provide digital data, the digital signals are still transmitted by using
analog carrier waves.
Multiple Choice
Q5. What is the function of a CSU/DSU?
Page 3 of 127
,Tomsho – Guide to Network Essentials, 9e | Question Bank Cognero XML – Version 7
■ A. It creates an analog connection between a LAN device, such as a router, and the WAN link from
the service provider.
✓ B. It creates a digital connection between a LAN device, such as a router, and the WAN link
from the service provider.
■ C. It converts analog signals into digital signals.
■ D. It connects routers to switches.
Rationale:
A channel service unit/data service unit (CSU/DSU) is a device (actually two devices that are usually combined)
that creates a digital connection between a LAN device, such as a router, and the WAN link from the service
provider. The WAN link is usually a T-carrier technology, such as T1 or T3.
Multiple Response (select all that apply)
Q6. What is the difference between an analog signal and a digital signal? Choose all that apply.
✓ A. An analog signal is a signal that varies over time continually and smoothly.
■ B. A digital signal is a signal that varies over time continually and smoothly.
■ C. An analog signal is 0v or 5v (with no value used between the two).
✓ D. A digital signal is 0v or 5v (with no value used between the two).
Rationale:
A digital signal works like a light bulb with a standard switch: it can be off, giving no light, or fully on, shining at
maximum brightness. An analog signal, on the other hand, is like a light bulb with a dimmer switch. It provides a
smooth range of brightness from off to fully on, with varying levels in between. Another example is the difference
between listening to a vinyl record and a digital download. Vinyl records are analog and capture all sound
frequencies. By contrast, digital recordings cut off some high and low frequencies. This is why music aficionados
favor listening to music on vinyl.
Multiple Response (select all that apply)

meters.
✓ C. Internetworks are confined to a building or campus where the internetworks owner owns
and operates all the technology.
■ D. LANs use serial communication technologies that can span distances measured in miles.
Rationale:
WANs use the services of carriers or service providers, such as phone companies and ISPs, for network
connections, whereas internetworks are confined to a building or campus where the internetworks owner owns and
operates all the technology.
Multiple Choice

Q9. What is the purpose of a leased line?
■ A. A leased line provides a temporary point-to-point connection from the customer's LAN through
the provider's network and to the destination network. It provides temporary, secure, and dedicated
bandwidth.
■ B. A leased line provides a dedicated point-to-multipoint connection from the customer's LAN
through the provider's network and to the destination network. It provides secure and dedicated
bandwidth.
✓ C. A leased line provides a dedicated point-to-point connection from the customer's LAN
through the provider's network and to the destination network. It provides permanent, secure,
and dedicated bandwidth.
■ D. A leased line provides a temporary point-to-multipoint connection from the customer's LAN
through the provider's network and to the destination network. It provides secure and dedicated
bandwidth.
Rationale:
A leased line offers a dedicated point-to-point connection that links the customer's local area network (LAN) to the
destination network via the provider's infrastructure. This connection provides permanent, secure, and exclusive
bandwidth, which is constrained only by the provider's technology and the amount that the customer is willing to
invest. Essentially, customers rent this network connection.

wires and over longer distances.
Rationale:
T-carriers originated when the dominant phone company at the time, AT&T;, wanted to be able to carry multiple
phone conversations over the same pair of wires and over longer distances. By digitizing voice data and organizing
phone conversations into time slots on the media, AT&T; accomplished its goal, and the T-carrier technology was
born.
Multiple Choice
Q11. How does the signaling method time division multiplexing (TDM) work?
■ A. All channels work on the same time slot regardless of the number of channels for a particular
purpose.
✓ B. It allocates a time slot for each channel, making it possible to extract any number of
channels for a particular purpose.
■ C. There is a maximum number of channels that can be used at any one time.

different portion for another purpose.
■ B. Fractionalization means that each T-carrier line is used to send data and a different DSL line is
used to receive data.
■ C. Fractionalization means that you can rent one channel and sublet another channel to another
company.
■ D. Fractionalization means that 24 64-Kbps channels can be turned into 64 24-Kbps channels.

Multiple Choice
Q22. Dabney lives 100 miles away from his in-laws, who often encounter problems with their
computers. To assist them more easily, he has decided to set up a VPN. This will enable him to log
into their computers and fix any issues they might encounter. What type of VPN service would best
suit this situation?
■ A. RDP
■ B. Remote Desktop Gateway
✓ C. GoToMyPC
■ D. VNC
Rationale:
GoToMyPC, like LogMeIn, is one of the best VPNs for this scenario because it offers several authentication
methods for both the host and client that other types of VPNs do not provide, and no VPN server is required to use
them.
Multiple Choice
Q23. What is cloud computing?
■ A. Cloud computing is used for making backups on individual computers.
■ B. Cloud computing is how the Internet creates data.
✓ C. Cloud computing is a way to access data, applications, and processing power over the
Internet. Instead of buying hardware and software, users pay for what they use.
