A) Impulse noise
B) White noise
C) Crosstalk
D) Impulse noise.

Accepted Answer

B

Question 3

What is the primary reason we create networks?
A) To exchange information
B) To share scarce or expensive resources
C) To allow distributed organizations to act as if they are centrally located
D) To allow centrally located organizations to act as if they are distributed

Accepted Answer

The primary reason for creating networks is to exchange information, enabling communication and data sharing between connected devices.

Question 4

The TCP/IP network model was developed after the OSI Reference Model.

Accepted Answer

The TCP/IP model was developed in the 1970s, predating the OSI Model, which was standardized in 1984.

Question 5

UDP is a connection-oriented datagram protocol.

Accepted Answer

UDP (User Datagram Protocol) is a connectionless protocol, not requiring a connection to be established before data is exchanged.

Question 6

In ____ polling, the central control unit, usually a server, polls each client to determine if it has traffic to transmit.
A) roll ahead
B) roll-call
C) go-ahead
D) call-ahead

Accepted Answer

In roll-call polling, a central control unit (often a server) sequentially polls each client in a network to check if they have data to transmit, ensuring orderly communication.

Question 7

Protocols that are widely accepted become standards.

Accepted Answer

Protocols that gain wide acceptance often evolve into standards as they become the norm for how systems communicate and interact, ensuring interoperability and compatibility across different devices and platforms.

Question 8

Which type of multiplexing is found exclusively in fiber-optic communications?
A) Phase division multiplexing
B) Frequency division multiplexing
C) Time division multiplexing
D) Wave division multiplexing

Accepted Answer

Wave Division Multiplexing (WDM) is unique to fiber-optic communications, allowing multiple optical carrier signals to be multiplexed onto a single optical fiber by using different wavelengths (colors) of laser light. This technique enables the fiber to carry multiple signals simultaneously, significantly increasing its capacity.

Question 9

Logical topologies indicate how networks function.

Accepted Answer

Logical topologies refer to the way data flows within a network, independent of its physical design, indicating how networks function at a conceptual level.

Question 10

____ is the interconnection of groups or systems with the purpose of exchanging information.
A) Multiplexing
B) Channeling
C) Networking
D) Data communications

Accepted Answer

Networking is the process of connecting computers, systems, or groups to exchange information, share resources, and communicate.

Question 11

Which port number is used by the Telnet protocol?
A) 20
B) 21
C) 22
D) 23

Accepted Answer

Telnet uses port number 23 for its network protocol for executing commands and services over a network.

Question 12

____ uses analog frequencies to encode one or more bits, by measuring the height of the signal.
A) Amplitude shift keying (ASK)
B) Frequency shift keying (FSK)
C) Pulse amplitude modulation (PAM)
D) Phase shift keying (PSK)

Accepted Answer

The answer of ____ uses analog frequencies to encode one...

Question 13

Which network typically covers a region the size of a municipality, county, or district?
A) Metropolitan area network
B) Wide area network
C) Campus area network
D) Local area network

Accepted Answer

A Metropolitan Area Network (MAN) is designed to extend over an entire city, municipality, or similar sized geographic area, providing connectivity to a wide range of users and services within this region.

Question 14

Which term refers to the loss of signal strength as the signal moves across media?
A) Distortion
B) Jitter
C) Attenuation
D) Impulse noise

Accepted Answer

Attenuation refers to the reduction in signal strength as it travels through a medium, such as a cable or air.

Question 15

The standard for wireless networks falls under IEEE ____.
A) 802.3
B) 802.5
C) 802.11
D) 802.21

Accepted Answer

The IEEE 802.11 standard is the set of standards for implementing wireless local area network (WLAN) computer communication in various frequencies, including but not limited to 2.4, 5, and 60 GHz frequency bands.

Question 16

____ is now the de facto industry standard for short range wireless communications between devices.
A) Infrared
B) Bluetooth
C) Wi-Fi
D) Microwave

Accepted Answer

Bluetooth has become the de facto industry standard for short-range wireless communications, allowing devices to connect and exchange data over short distances.

Question 17

In ____ networks, the individual users or clients directly interact with one another, sharing resources without the benefit of a central repository or server.
A) local area network
B) peer-to-peer
C) server-based
D) body area

Accepted Answer

Peer-to-peer networks allow individual users or clients to interact directly with one another, sharing resources without the need for a central server or repository.

Question 18

Which cable is all but obsolete in data communications with the exception of its use in the cable television infrastructure to support cable modem-based high-speed Internet access for residences?
A) Coaxial
B) UTP
C) STP
D) Fiber-optic

Accepted Answer

Coaxial cable is largely considered obsolete in many data communication applications, except for its continued use in cable television infrastructure to support high-speed Internet access through cable modems. This is because other types of cabling, such as UTP (Unshielded Twisted Pair), STP (Shielded Twisted Pair), and fiber-optic cables, offer better performance and reliability for most modern data communication needs outside of this specific use case.

Question 19

Which standards organization is the global leader in developing and publishing international standards?
A) American National Standards Institute (ANSI)
B) The Internet Society (ISOC)
C) International Telecommunications Union (ITU)
D) International Organization for Standardization (ISO)

Accepted Answer

The International Organization for Standardization (ISO) is recognized globally for developing and publishing international standards across a wide range of industries and sectors.

Question 20

Which protocol is considered to be a dominant protocol for local area networking?
A) Ethernet
B) Token ring
C) PPP
D) FDDI

Accepted Answer

Ethernet is widely recognized as the dominant protocol for local area networks (LANs) due to its widespread adoption, flexibility, and efficiency in handling data traffic within local network environments.
