Question 8

________ computing pools various hardware and software components to create a single IT environment with shared resources.
A) Chambered
B) Grid
C) Open
D) Utility

Accepted Answer

Grid computing pools various hardware and software components to create a single IT environment with shared resources, allowing for complex calculations or tasks to be processed more efficiently by distributing the workload across multiple machines.

Question 9

Which of the following cloud computing characteristics represents the organization's ability to access its computing resources using any device?
A) Encompasses the characteristics of utility computing
B) Scalability
C) Uses broad network access
D) Virtualization

Accepted Answer

Broad network access is a characteristic of cloud computing that allows resources to be accessed over the network through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations). This enables the organization's ability to access its computing resources using any device.

Question 10

When IT was first introduced into the business environment, organizations initially used ____________.
A) Cloud computing
B) LANs
C) stand-alone mainframes
D) stand-alone PCs

Accepted Answer

When IT was first introduced into the business environment, organizations primarily utilized stand-alone mainframes. These were large, powerful computers that were used for processing large amounts of data and were not initially connected to other computers or networks.

Question 11

Enterprise computing was first introduced in the ________.
A) 1970s
B) 1980s
C) 1990s
D) 2000s

Accepted Answer

The answer of Enterprise computing was first introduced in the...

Question 12

Which of the following cloud computing characteristics addresses the business need to increase or decrease capacity when necessary (for example, retailers frequently need much more computational capacity on Black Friday)?
A) Providing on-demand self-service
B) Scalability
C) Uses broad network access
D) Virtualization

Accepted Answer

Scalability is the characteristic of cloud computing that allows businesses to adjust their computing resources as needed, increasing or decreasing capacity in response to demand, such as the surge experienced by retailers on Black Friday.

Question 13

Which of the following cloud computing characteristics represents the "pay-as-you-go" concept?
A) Encompasses the characteristics of grid computing
B) Encompasses the characteristics of utility computing
C) Providing on-demand self-service
D) Virtualization

Accepted Answer

The "pay-as-you-go" concept is a characteristic of utility computing, which means customers pay only for the computing resources they use, similar to how utility services (like electricity) are billed.

Question 14

________ computing allows service providers to make computing resources and infrastructure management available to customers as needed and then charges a ________ rate.
A) Grid; fixed
B) Grid; variable
C) Utility; fixed
D) Utility; variable
