Question 1

Enterprises are moving away from ad hoc adoption of mobile devices and network infrastructure to a more strategic planning build-out of their mobile capabilities.

Accepted Answer

Enterprises are recognizing the need for a more strategic approach to incorporating mobile devices and network infrastructure into their operations, rather than just adopting them on an ad hoc basis. This allows for better integration and management of mobile capabilities.

Question 2

Standards with labels such as "802.11b", "802.11a", "802.11g" and so on are different kinds of Wi-Fi networking standards.

Accepted Answer

This is true. The labels "802.11b", "802.11a", "802.11g" and so on are actually different standards in the IEEE 802.11 family of wireless networking technologies, which are commonly referred to as Wi-Fi.

Question 3

According to your text, developing software for wireless devices had been challenging because the market is fragmented into devices with different CPUs, operating systems, storage media, and mobile platform environments.

Accepted Answer

The text states that developing software for wireless devices had been challenging because of the market fragmentation.

Question 4

An intranet is a widely used type of network based on Internet technology
e.g. browsers, Internet protocols, etc.) but focused on serving the internal informational needs of a company.

Accepted Answer

An intranet is indeed based on Internet technology but is used for internal communication and information sharing within a company rather than for public access.

Question 5

Different CPUs, operating systems, storage media, and mobile platform environments characterize the mobile device marketplace. This creates significant challenges for software developers.

Accepted Answer

The statement is true. The diversity of mobile device marketplace creates challenges for software developers due to the need to create apps that work across different CPUs, operating systems, storage media, and mobile platform environments.

Question 6

In most organizations today, when the network goes down, it causes almost complete disruption of productivity or service, including lost sales, financial consequences and inability to process payroll and inventory.

Accepted Answer

When the network goes down, it can cause significant disruption to productivity and service, including lost sales, financial consequences, and other negative impacts on business operations. This is why network uptime and reliability are such critical concerns for modern organizations.

Question 7

According to the Cisco Visual Networking Index VNI) Mobile Data Traffic Forecast, 2011-2016, most mobile devices will be smaller in size than they are today.

Accepted Answer

The Cisco Visual Networking Index (VNI) Mobile Data Traffic Forecast does not predict the physical size of mobile devices but rather focuses on the growth and usage patterns of mobile data traffic.

Question 8

According to the Cisco Visual Networking Index VNI) Mobile Data Traffic Forecast, 2011-2016, more users will have more powerful mobile devices and use more bandwidth.

Accepted Answer

The forecast predicts an increase in both the number of mobile users with powerful devices and their usage of mobile data bandwidth.

Question 9

When problems inevitably occur
e.g., a network crash), trained staff are needed to restore the network promptly or to switch to a backup system to minimize disruption during the restoration.

Accepted Answer

Trained staff are crucial in restoring the network promptly or switching to a backup system to minimize disruption during network problems such as a network crash.

Question 10

According to your text, developing software for wireless devices had been challenging because until recently, the market was not large enough to justify large scale investment in the development of software apps.

Accepted Answer

The answer of According to your text, developing software for...

Question 11

In terms of collaboration, a decentralized organization is more responsive to opportunities and problems than a centralized organization where top-level managers, who are typically less involved in day-to-day operations, make decisions.

Accepted Answer

A decentralized organization allows for greater communication and decision-making among employees who are closer to the ground, leading to faster and more informed decision-making in response to opportunities and problems. In contrast, a centralized organization may require decisions to go through a lengthy approval process by top-level managers who may not have as much knowledge of the situation at hand.

Question 12

Traditionally, various information services-data, documents, voice, and video-have functioned independently of each other. Multiple networks were needed because of the lack of interoperability or connectivity) between devices.

Accepted Answer

Traditionally, different information services operated independently and required multiple networks due to the lack of connectivity between devices.

Question 13

There are three general types of mobile networks: wide area networks WANs), WiMAX, and local area networks LANs).

Accepted Answer

This statement is true. Wide area networks (WANs) cover a large geographical area, WiMAX (Worldwide Interoperability for Microwave Access) is a type of wireless communication standard used for broadband internet access, and local area networks (LANs) cover a smaller area such as a single building or campus.

Question 14

When problems inevitably occur
e.g., a network crash), modern companies typically have plans for redeploying their workforce to duties or activities that do not require a computer network to function. This allows them time to request bids and proposals from IT firms that can fix the problem for a competitive price.

Accepted Answer

Modern companies usually have IT disaster recovery plans in place that include immediate measures to restore network functionality, often involving in-house IT staff or pre-arranged agreements with IT service providers, rather than redeploying their workforce to non-network tasks while seeking competitive bids for repairs.

Question 15

Network infrastructure alone does not improve business performance. Rather, it is how network capabilities combine with collaboration technologies to support employees and cross-functional work, connect remote locations, service customers, and coordinate with supply chain partners.

Accepted Answer

Network infrastructure is important, but it is the combination of network capabilities and collaboration technologies that can truly drive business performance improvement.

Question 16

WiMAX is the part of the wireless infrastructure that transmits voice, data, and video over high frequency radio signals to businesses, homes, and mobile devices.

Accepted Answer

WiMAX is a wireless technology that facilitates the transmission of data, voice, and video using high-frequency radio signals over long distances to a range of devices.

Question 17

WANs for mobile computing are known as WWANs wireless wide area networks).

Accepted Answer

WWANs stand for wireless wide area networks and are used for mobile computing, so the statement is true.

Question 18

Most residential wireless networks are based on WiMAX technology for connecting computers and printers to the wired LAN.

Accepted Answer

Most residential wireless networks use Wi-Fi technology, not WiMAX technology.

Question 19

Enterprises are moving away from strategic planning for mobile devices and network infrastructure and are instead rapidly expanding their mobile networks and device deployment on an ad hoc basis to keep up with demand and competitive threats.

Accepted Answer

Enterprises are increasingly focusing on strategic planning for mobile devices and network infrastructure to ensure security, manageability, and scalability, rather than expanding their networks and device deployment on an ad hoc basis. Strategic planning helps in addressing the challenges of demand and competitive threats in a more structured and efficient manner.

Question 20

An intranet is a widely used type of network based on Internet technology
e.g. browsers, Internet protocols, etc.) but focused on communicating with customers and/or supply chain partners.

Accepted Answer

The description provided is actually describing an extranet, not an intranet. An intranet is a network that is internal to a company or organization and used for internal communications and collaboration purposes.
