Question 1

What connects a group of computers in close proximity,such as in a school or office setting?
A)Metropolitan area network (MAN)
B)Local area network (LAN)
C)Wide area network (WAN)
D)Secure area network (SAN)

Accepted Answer

A local area network (LAN) connects a group of computers in close proximity, usually within a building or campus. MAN and WAN refer to larger networks that can connect computers over larger distances, while SAN refers to a specialized network for data storage and retrieval.

Question 2

What is a large computer network usually spanning a city or a specific infrastructure like a college known as?
A)Metropolitan area network (MAN)
B)Local area network (LAN)
C)Wide area network (WAN)
D)Secure area network (SAN)

Accepted Answer

A metropolitan area network (MAN) is a large computer network that spans a specific geographic area, such as a city or a college campus. It is larger than a local area network (LAN) but smaller than a wide area network (WAN). MANs are typically used to connect multiple LANs within a specific geographic area.

Question 3

What spans a large geographic area such as a state,province,or country,similar to the Internet?
A)Metropolitan area network (MAN)
B)Local area network (LAN)
C)Wide area network (WAN)
D)Secure area network (SAN)

Accepted Answer

A wide area network (WAN) spans a large geographic area such as a state, province, or country, similar to the Internet. A metropolitan area network (MAN) connects devices within a city or metropolitan area, while a local area network (LAN) connects devices within a smaller area such as a home or office. A secure area network (SAN) is a specialized network designed for data storage and retrieval.

Question 4

One of the main challenges of business mobility is protecting against theft.

Accepted Answer

Business mobility often involves employees carrying valuable devices and data with them outside of the office, making them vulnerable to theft. It is important for companies to have security measures in place to protect against theft and ensure the safety of their assets.

Question 5

Which of the following includes the three primary network types?
A)LAN,WAN,SAN
B)LAN,WAN,MAN
C)LAN,SAN,XAN
D)LAN,WAN,XAN

Accepted Answer

The three primary network types are LAN (Local Area Network), WAN (Wide Area Network), and MAN (Metropolitan Area Network). Choice B includes all three of these types. Choice A includes LAN, WAN, and SAN (Storage Area Network), which is not one of the primary network types. Choice C includes LAN and SAN, but XAN is not a commonly recognized network type. Choice D includes LAN and WAN, but again, XAN is not a recognized network type.

Question 6

War chalking is deliberately searching for Wi-Fi signals while driving by in a vehicle.

Accepted Answer

War chalking is the act of marking pavement with symbols to indicate the presence of Wi-Fi signals in a particular area. It does not involve driving around in a vehicle to search for signals.

Question 7

Wired equivalent privacy (WEP)is an encryption algorithm designed to protect wireless transmission data.

Accepted Answer

WEP is an encryption algorithm used to protect wireless transmission data.

Question 8

What is the largest and most important network that has evolved into a global information superhighway?
A)Internet
B)Intranet
C)Extranet
D)LAN

Accepted Answer

The Internet is the largest and most important network that has evolved into a global information superhighway. It is a global network of networks that connects billions of devices worldwide and facilitates communication, information sharing, and commerce on a global scale.

Question 9

WLANs that use Wi-Fi have a built-in security mechanism called Wi-Fi Protected Access (WPA),a wireless security protocol to protect Wi-Fi networks.It is an improvement on the original Wi-Fi security standard,Wired Equivalent Privacy (WEP),and provides more sophisticated data encryption and user authentication.

Accepted Answer

Wi-Fi Protected Access (WPA) is a wireless security protocol that provides more advanced data encryption and user authentication compared to the original Wi-Fi security standard, Wired Equivalent Privacy (WEP).

Question 10

Instant access to customer profiles,account history,and current order status significantly improves the quality of interactions with customers,suppliers,and business partners.

Accepted Answer

Having access to customer profiles, account history and current order status provides important context and information for communicating effectively with customers, suppliers and business partners. This allows for more personalized and efficient interactions, resulting in improved quality of service.

Question 11

LBS differ from RFID in that an LBS cannot track and monitor objects such as inventory.

Accepted Answer

This statement is incorrect. LBS (Location-based services) can track and monitor objects, including inventory, using technologies such as GPS, Wi-Fi, and Bluetooth. RFID (Radio-frequency identification), on the other hand, can track and monitor objects using radio waves and does not rely on location-based technologies.

Question 12

What are the five elements that are needed to create a connected world or a network?
A)Categories,programs,alternatives,people,and core philosophy
B)Program,providers,access,mechanics,and teachers
C)Categories,providers,access technologies,protocols,and convergence
D)LAN,WAN,MAN,PAN,and SAN

Accepted Answer

Categories help identify different types of devices and services that can be connected, providers offer the infrastructure to connect these devices and services, access technologies allow for communication between devices and services, protocols define how devices and services communicate with each other, and convergence enables different devices and services to work together seamlessly. Together, these elements create a connected world or network. Options A and B both have some relevant elements but they do not cover all the necessary components. Option D lists different types of networks rather than elements needed to create a connected world or network.

Question 13

What enables telecommunications or the exchange of information (voice,text,data,audio,and video)?
A)Computer networks
B)Email
C)HTML
D)Technology sourcing

Accepted Answer

Computer networks enable telecommunications by providing a means for devices to connect and exchange information, such as voice, text, data, audio, and video.

Question 14

With the power of a wireless network,business professionals can take advantage of mobility allowing them to work from anywhere,at any time,using many different devices.

Accepted Answer

A wireless network allows for connectivity without requiring physical connection to a device, enabling business professionals to work from anywhere on a variety of devices.

Question 15

WLANs that use Wi-Fi have a built-in security mechanism called Wi-Fi protected access (WPA),a wireless security protocol to protect Wi-Fi networks.

Accepted Answer

WPA is a wireless security protocol that is built into Wi-Fi networks to provide security.

Question 16

War driving is the practice of tagging pavement with codes displaying where Wi-Fi access is available.The codes for war driving tell other users the kind of access available,the speed of the network,and if the network is secured.

Accepted Answer

War chalking is the practice of tagging pavement with codes displaying where Wi-Fi access is available.The codes for war chalking tell other users the kind of access available,the speed of the network,and if the network is secured.

Question 17

Wireless technology offers the opportunity to redesign and often complicates the work flow processes to be faster,yet more expensive,and more time-consuming.

Accepted Answer

Wireless technology offers the opportunity to redesign and simplify those processes to be faster,cheaper,and more responsive,and to eliminate redundant activities,integrate activities and services,and redistribute tasks.

Accepted Answer

Wireless networks provide the advantage of enhancing mobility and freeing activities from physical locations.

Question 20

LANs,WANs,and MANs all provide users with an accessible and reliable network infrastructure.Which of the below are the most important network differentiating dimensions?
A)Reliability and timing
B)Confidentiality and performance
C)Security and cost
D)Cost and performance

Accepted Answer

The most important network differentiating dimensions are cost and performance. LANs, WANs, and MANs vary in terms of the cost to implement and maintain, as well as the performance they offer in terms of speed and bandwidth. While reliability, confidentiality, security, and timing are all important factors, they do not necessarily differentiate these types of networks from each other as much as cost and performance do.
