Question 1

An enterprise's network capability will be unreliable or deteriorate without proper planning,maintenance,management,upgrades,and bandwidth of the network to insure that it has sufficient capacity and connectivity to link people,locations,and data.

Accepted Answer

Without proper planning, maintenance, management, upgrades, and sufficient bandwidth, an enterprise's network capability will be unreliable or deteriorate over time. It is important to ensure that the network has enough capacity and connectivity to link people, locations, and data.

Question 2

Bandwidth is the throughput capacity,or speed,of a network,which depends on what protocol is used.

Accepted Answer

Bandwidth is indeed the throughput capacity or speed of a network, which is influenced by various factors, including the protocol used.

Question 3

The 802.11b standard improves upon other 802.11 Wi-Fi standards by adding multiple-input multiple-output (MIMO)and many other newer features.

Accepted Answer

The 802.11b standard does not include MIMO technology. It does improve upon earlier standards by offering higher data transfer rates up to 11 Mbps.

Question 4

Businesses have learned effective strategies to cope with a world that is far more competitive,dynamic,and connected;to counteract the influence of Web 2.0 technologies;and to maintain traditional business models.

Accepted Answer

Businesses have adapted to leverage Web 2.0 technologies rather than counteract them, integrating these tools to enhance connectivity, engagement, and innovation in their business models.

Question 5

Transmission of a signal over a series of networks is made possible by switches and routers,which are hardware devices,and nodes on the network.

Accepted Answer

Switches and routers are hardware devices that facilitate the transmission of signals across multiple networks. Nodes, which can be both hardware and software components, also play a crucial role in network communication.

Question 6

Messaging and collaboration tools include older communications media such as e-mail,videoconferencing,fax,and IM-and Web 2.0 media such as blogs,podcasts,RSS,wikis,and VoIP.

Accepted Answer

This statement is true. Messaging and collaboration tools encompass a range of communication media, both old and new, including e-mail, videoconferencing, fax, instant messaging, blogs, podcasts, RSS, wikis, and VoIP.

Question 7

Users can get 4G wireless connectivity through one of two standards: WiMAX or LTE.

Accepted Answer

WiMAX and LTE are the two main standards used for providing 4G wireless connectivity.

Question 8

__________ shows the power of the individual in the connected age-a better research tool than major corporations had in the 1990s.
A)Facebook
B)Google
C)Microsoft
D)eBay

Accepted Answer

Google is a search engine that allows individuals to access vast amounts of information and has become a powerful tool for research. It gives more power to individuals in the connected age than major corporations had with research tools in the past. Facebook does not have a research tool, Microsoft is primarily a software company, and eBay is an online marketplace.

Question 9

__________ enable(s)anyone to call or share files for free,increases the connections in our lives,and create forces whose impacts are not yet known.
A)VoIP
B)Wikis
C)WiMAX
D)All of the above

Accepted Answer

All of the choices enable anyone to call or share files for free, increase the connections in our lives, and create forces whose impacts are not yet known.

Question 10

Several factors are driving the need for messaging and collaboration.All of the following are driving factors except:
A)people need to work together and share documents.
B)groups make most of the routine and easy decisions in organizations.
C)organizational decision making is difficult when team members are geographically spread out and working in different time zones.
D)nearly 87 percent of employees around the world work in remote offices.

Accepted Answer

While collaboration may lead to better decision making, the statement that "groups make most of the routine and easy decisions in organizations" is not a driving factor for messaging and collaboration.

Question 11

A centralized organization is more responsive to opportunities and problems than a decentralized organization where senior managers,who are less involved in daily operations than lower-level managers,make decisions.

Accepted Answer

In a decentralized organization, lower-level managers have more authority to make decisions and take actions that are responsive to opportunities and problems at their level. This can result in faster response times and more efficient problem-solving. In contrast, a centralized organization may have slower response times because senior managers may need to be consulted and involved in decision-making.

Question 12

Network performance is measured by its data transfer capacity.

Accepted Answer

Network performance is typically measured in terms of data transfer capacity or speed, which refers to the amount of data that can be transmitted over the network in a given time period. Other factors that can affect network performance include latency, packet loss, and network congestion.

Question 13

Which of the following is a dysfunction of the group process?
A)Social pressures of conformity can lead to groupthink.
B)A group may produce synergy during problem solving.
C)Group members may have their egos embedded in the decision,and so they may be committed to the solution.
D)Groups are better than individuals at understanding problems.

Accepted Answer

Groupthink, which occurs when a group makes a faulty decision due to social pressures to conform and to favor group consensus over critical evaluation of alternatives, is a frequent dysfunction of the group process. B, C, and D describe positive outcomes of the group process.

Question 14

The distinguishing characteristic of packet switching is that once a connection is made between the source and destination,the path of the signal along the nodes is dedicated and exclusive.

Accepted Answer

The distinguishing characteristic of packet switching is that the signal is divided into packets and each packet can take a different path through the network in order to reach its destination. This allows for more efficient use of network resources and can better handle varying levels of traffic.

Question 15

IP networks form the backbone of worldwide digital networking and enable the convergence of voice,data,and video.

Accepted Answer

IP networks are indeed the backbone of worldwide digital networking and facilitate the integration of voice, data, and video.

Question 16

According to the Cellular Telecommunications Industry Association,__________ is "a way of measuring the quantity of radio frequency energy that is absorbed by the body."
A)RF rate
B)carbon footprint
C)radiation rate
D)specific absorption rate (SAR)

Accepted Answer

The Cellular Telecommunications Industry Association defines specific absorption rate (SAR) as a way of measuring the amount of radio frequency energy that is absorbed by the body.

Question 17

Pressures to deliver secure service to customers and business partners at reduced costs,to be environmentally responsible,and to support the 24/7 data needs of mobile and remote workers have all increased the demands on corporate networks.

Accepted Answer

The statement is true.

Question 18

Apple's first 4G phone,the HTC EVO 4G was released in summer 2010 with speeds 10 times greater than 3G phones.

Accepted Answer

Apple's first 4G phone was the iPhone 5, which was released in September 2012. The HTC EVO 4G was actually released by HTC, not Apple, in June 2010.
