Question 1

Teleaction increases the value of local mediocrity.

Accepted Answer

Teleaction, by broadening access to global talent and resources, often increases competition and quality, potentially diminishing the relative value of local mediocrity by comparison.

Question 2

How are communications secured from snooping in a virtual private network?

Accepted Answer

The answer of How are communications secured from snooping in...

Question 3

What is a virtual private cloud? What are its advantages?

Accepted Answer

The answer of What is a virtual private cloud? What...

Question 4

Benefits of using the cloud include all of the following EXCEPT ________.

Accepted Answer

Use of dumb terminals is not a benefit of using the cloud.

Question 5

Software as a system is a fundamental cloud type.

Accepted Answer

Software as a Service (SaaS) is a cloud type, not Software as a System.

Question 6

Cloud computing can enable organizations to readily obtain elastic resources at very low costs.

Accepted Answer

Cloud computing allows organizations to easily scale up or down their computing resources as needed, without having to invest in expensive hardware or infrastructure. This "pay as you go" model often results in lower overall costs for the organization.

Question 7

Telediagnosis uses telecommunications to link surgeons to robotic equipment at distant locations.

Accepted Answer

Telediagnosis refers to the use of telecommunications to diagnose patients remotely, not to link surgeons to robotic equipment.

Question 8

Which of the following is likely to be a consequence of cloud computing in the future?

Accepted Answer

Cloud computing enables organizations to obtain elastic resources without the need for expensive hardware and personnel costs associated with maintaining a data center. As cloud computing becomes more widespread and competition between cloud providers increases, the cost of obtaining elastic resources is likely to decrease.

Answer: A and C are incorrect.
 Cloud computing reduces the need for organizations to set up their own computing infrastructure and employ personnel to manage information systems. The preference is likely to shift towards cloud computing due to its numerous benefits such as increased flexibility, scalability, and cost-effectiveness. Therefore, A is incorrect. Moreover, while cloud computing may lead to a shift in the types of skills and expertise required in the workforce, it is unlikely to reduce the demand for employees who know how to use and manage information systems as technology continues to advance, creating new opportunities for skilled professionals. Therefore, C is also incorrect. D is not a likely consequence of cloud computing but rather depends on various socio-economic factors.

Question 9

Cloud vendors benefit from ________ because the average cost of production decreases as the size of the operation increases.

Accepted Answer

Economies of scale refer to the cost advantage that an organization has as it expands its operations. Cloud vendors are able to take advantage of this through a larger customer base and more efficient use of resources, resulting in a lower average cost of production. The other options (A, B, and D) do not directly relate to the cost advantage gained through economies of scale.

Question 10

A company decides to run advertising during the NCAA Final Four tournament. They are not sure how traffic their website will get so they decide to lease what they think they need and can easily add more if necessary. This is called ________.

Accepted Answer

Leasing what they need and being able to easily add more is an example of resource elasticity, which refers to the ability of a system or infrastructure to automatically adjust its resources to accommodate varying levels of demand. Pooled resources, client-server architecture, and mainframe usage do not accurately describe the situation presented in the question.

Question 11

Cloud computing architecture allows employees to use devices connected with IoT.

Accepted Answer

Cloud computing architecture enables access to data, applications, and services from any device connected to the internet, including IoT devices.

Question 12

A(n) ________ is an information system (IS) that provides computer-based activity at a distance.

Accepted Answer

A remote action system allows users to perform computer-based activities from a distance, such as working on a remote server or accessing software on another computer. The other options are not directly related to computer-based activities at a distance.

Question 13

A virtual private cloud allows organizations to gain the advantages of cloud storage for the portion of data that need not be physically controlled.

Accepted Answer

A virtual private cloud (VPC) provides a virtualized network infrastructure that replicates traditional data center technologies. It allows organizations to securely use cloud resources while maintaining control over their data. With a VPC, organizations can take advantage of the scalability, flexibility, and cost-effectiveness of cloud storage without sacrificing control over their data.

Question 14

Remote action systems increase time and travel expenses.

Accepted Answer

Remote action systems, such as video conferencing and email, actually decrease the need for travel and can ultimately save time and travel expenses.

Question 15

Explain how a user in a hotel in Los Angeles can connect to a local area network (LAN) at a Michigan site using a virtual private network.

Accepted Answer

The answer of Explain how a user in a hotel...

Question 16

Large Web farms are likely to replace in-house servers used by small companies due to the benefits of cloud computing.

Accepted Answer

Large web farms provide scalable computing resources at a lower cost than maintaining in-house servers, making them an attractive option for small companies looking to save on infrastructure costs.

Question 17

A remote system designed by Alpha Solutions uses cameras and motion-sensing equipment to issue tickets for traffic violations. This system is an example of ________.

Accepted Answer

The system described is primarily used for law enforcement through the use of cameras and motion sensors to issue traffic violation tickets remotely, hence it is an example of telelaw enforcement.

Question 18

Until about the late 1980s, organizations primarily used ________ for their internal data processing needs?

Accepted Answer

Mainframes were typically used for internal data processing needs until the late 1980s, as they were capable of handling large amounts of data and provided reliable performance. Client-servers, the cloud, and scalable computers did not become widely used until later on.

Question 19

What is a private cloud? What are its limitations?

Accepted Answer

The answer of What is a private cloud? What are...

Question 20

Cloud computing is likely to lead to an increase in the number of technology-based startups.

Accepted Answer

Cloud computing provides startups with cost-effective and scalable computing resources, which reduces the barrier to entry and creates opportunities for innovative new businesses. Therefore, it is likely to lead to an increase in the number of technology-based startups.
