Question 1

Using virtualization methods,enterprises can respond to change more quickly and make better decisions in real time without physically moving their data,which significantly cuts costs.

Accepted Answer

Virtualization allows for better flexibility and agility in managing data, which can lead to cost savings for businesses.

Question 2

ISs do not exist in isolation,but rather exist within an organizational culture.

Accepted Answer

Information systems (ISs) are designed and implemented by organizations in order to meet their specific goals and objectives. As a result, ISs operate within a specific organizational culture, which can have a significant impact on their effectiveness and usability. For example, some organizations may have a culture that values innovation and experimentation, while others may prioritize efficiency and risk aversion. These cultural factors can influence everything from the design of the ISs themselves to the way that employees interact with them on a day-to-day basis. Therefore, it is important to consider the organizational context in which an IS exists when evaluating its performance or potential impact.

Question 3

Because cloud is still a relatively new and evolving business model,the decision to select a cloud service provider should be approached with even greater diligence than other IT decisions.

Accepted Answer

Cloud is a relatively new business model and is evolving constantly. Hence, selecting a cloud service provider should be approached with greater diligence than other IT decisions.

Question 4

A company's application architecture describes the hardware and software infrastructure that supports applications and their interactions.

Accepted Answer

The answer of A company's application architecture describes the hardware...

Question 5

Cloud computing solutions are growing in popularity with organizations because they reduce the burden of deploying,provisioning,and updating software apps.

Accepted Answer

Cloud computing solutions do indeed reduce the burden of deploying, provisioning, and updating software apps, which is why they are becoming more popular with organizations.

Question 6

A data center is designed and built to be scalable so the amount of storage and the workload it can handle changes without purchasing and installing more equipment.

Accepted Answer

A data center designed and built to be scalable often requires purchasing and installing more equipment to handle increased storage needs or workload, as scalability involves physical and/or virtual expansion capabilities.

Question 7

Storage virtualization is the pooling of physical storage from multiple network storage devices into what appears to be a single storage device that is managed from a central console.

Accepted Answer

Storage virtualization allows multiple storage devices to be viewed and managed as a single entity from a central console, providing simplified management and greater flexibility in storage allocation.

Question 8

Decision support systems are interactive applications that support highly structured decision making scenarios.

Accepted Answer

Decision support systems are designed to assist in making decisions in situations that are not highly structured, often dealing with complex problems where the data may be uncertain or incomplete.

Question 9

A main difference between a cloud and a data center is that a cloud is an off-premise form of computing that stores data on the Internet.

Accepted Answer

A cloud is a remote location accessed via the internet that stores and manages data and applications, whereas a data center is a physical facility used to house computer systems and related components, such as telecommunications and storage systems.

Question 10

Software as a service (SaaS)apps are typically accessed over a network using a Web browser (no hardware or software to install)and paid for by a fixed subscription fee or on a per-use basis.

Accepted Answer

SaaS apps are indeed accessed over a network using a Web browser and paid for through a fixed subscription fee or on a per-use basis.

Question 11

The NSA's data center in Bluffdale,Utah is its largest spy data center where information from Google,Facebook,and Apple are stored.

Accepted Answer

The NSA's data center in Bluffdale, Utah is indeed its largest spy data center and stores information from various sources including Google, Facebook, and Apple.

Question 12

Virtualization is a technique that creates a virtualization layer and multiple virtual machines (VM)that run on a single physical machine.

Accepted Answer

This statement is true. Virtualization involves creating virtual machines that run on a single physical machine, typically through the use of a virtualization layer or hypervisor. This allows multiple operating systems and applications to run concurrently on the same hardware, increasing efficiency and flexibility for organizations.

Question 13

Companies or government agencies that need greater security and data confidentiality set up their own clouds on servers that they own.These are called protected clouds.

Accepted Answer

These are called private clouds, not protected clouds. Private clouds are cloud environments dedicated solely to the end user, typically within the user’s firewall and sometimes on-premise.

Question 14

On-premises data centers,virtualization,and cloud computing are types of IT infrastructures or computing systems.

Accepted Answer

The answer of On-premises data centers,virtualization,and cloud computing are types...

Question 15

A typical SLA in an informal agreement that describes levels of service using various attributes such as: availability,serviceability,performance,operations,billing,but not penalties associated with violations of such attributes.

Accepted Answer

A typical SLA is a formal agreement that not only describes levels of service but also includes penalties or consequences associated with violations of those levels.

Question 16

Cloud solutions typically require less bandwidth and place fewer demands on the organization's network or wide area network (WAN),reducing the risk of downtime.

Accepted Answer

Cloud solutions often require more bandwidth because data is frequently transferred over the internet between the organization and the cloud provider's data centers, potentially increasing the demands on the organization's network or WAN and affecting network performance.

Question 17

Virtual machines (VM)are specialized apps for designing and testing 3 Dimensional products such as trucks,cars,and mechanical devices.

Accepted Answer

While virtual machines can be used for a variety of purposes, they are not specifically designed for 3D product design and testing. There are, however, specialized software programs and applications that are designed for this purpose.

Question 18

The greatest strategic advantage of cloud computing solutions is that they are typically more secure than traditional software apps.

Accepted Answer

The statement is false. While cloud computing solutions can offer strong security measures, it is not an inherent advantage over traditional software apps. The level of security for both types of applications depends on various factors such as the specific software, the security measures put in place, and the level of access control.

Question 19

The National Climatic Data Center is an example of a public data center that stores and manages the world's largest archive of weather data.

Accepted Answer

The National Climatic Data Center, now known as the National Centers for Environmental Information, is a public data center that manages and stores the world's largest archive of weather data.

Question 20

Public clouds are single-tenant environments with stronger security and control for regulated industries and critical data.

Accepted Answer

Public clouds are multi-tenant environments where resources are shared among various users. While public cloud providers offer security measures, they may not offer the same level of control and security as private or hybrid clouds, which are better suited for regulated industries and critical data.
