Question 5

What are the three cloud computing service delivery models?

Accepted Answer

The three cloud computing service delivery models are Infrastructure as a Service (IaaS), Software as a Service (SaaS), and Platform as a Service (PaaS). IaaS provides access to computing infrastructure such as virtualized server space, storage and network. SaaS provides access to software applications that are hosted by a third-party provider, while PaaS provides a platform for developers to build and deploy their own applications. Option A, C and D are all incorrect service delivery models.

Question 6

Cloud computing allows users to connect via a web browser and stores all of their software documents 'in the cloud',which means there is no more need for users to have ___________.

Accepted Answer

Cloud computing eliminates the need for hard drives, physical servers, and software or processing power on users' devices. All of these resources are instead stored and accessed through the cloud.

Question 7

What is a facility used to house management information systems and associated components,such as telecommunications and storage systems?

Accepted Answer

A data centre is a facility used to house management information systems and associated components such as telecommunications and storage systems. A call centre is a facility used for handling incoming and outgoing customer calls. A delivery base is a location for receiving and dispatching goods for delivery. "Central centre" is not a commonly used term in the context of IT infrastructure.

Question 8

The most popular IaaS operation today is Amazon's Elastic Compute Cloud (EC2).The benefit when using Amazon as an IaaS includes ___________.

Accepted Answer

All the given options (A, B, and C) are correct benefits of using Amazon's EC2 as an IaaS. Customers can load, run, and control their own applications and environment and also create, run and stop services as required. Therefore, option D is the correct answer.

Question 9

What might change the way businesses operate,as well as the way people interact with technology?

Accepted Answer

Cloud computing has the potential to change the way businesses operate by allowing them to access software and data storage through the internet rather than relying on in-house hardware and servers. This can lead to cost savings and increased flexibility. It also changes the way people interact with technology by allowing them to access programs and data from any device with an internet connection, increasing mobility and collaboration.

Question 10

Which of the below is not contributing to e-waste?

Accepted Answer

An automobile is not an electronic device and therefore does not contribute to e-waste. The other three choices (VCR, microwave, and computer) are electronic devices that can contribute to e-waste when they are thrown away instead of being recycled or disposed of properly.

Question 11

What is cloud computing services changing?

Accepted Answer

Cloud computing services are changing the way people access, deliver, and use information. Therefore, all the answers are correct.

Question 12

One way a business can minimise the damage of a system crash is to have a _________ and recovery strategy in place.

Accepted Answer

The answer of One way a business can minimise the...

Question 13

What are the three pressures driving sustainable MIS infrastructures?

Accepted Answer

The three pressures driving sustainable MIS infrastructures are increases in electronic waste, energy waste, and carbon emissions. This means that the demand for technology and energy is increasing, resulting in more electronic waste and energy waste, which are harmful to the environment. Additionally, the production and use of technology contribute to carbon emissions, which have a negative impact on the environment. Therefore, the focus on sustainable MIS infrastructures is to find ways to reduce these three pressures and move towards a more sustainable future. Option A and D are incorrect because they do not identify the correct pressures driving sustainable MIS infrastructures. Option B is incorrect because it suggests that dynamic scaling is a pressure, which is not accurate.

Question 14

Which cloud computing model offers applications on a pay-per-use basis?

Accepted Answer

Software as a Service model offers applications on a pay-per-use basis where users can access software applications hosted by a provider through the internet.

Question 15

Grid computing takes advantage of the available 75 per cent of unused processing power of a computer and links thousands of individual computers around the world creating a _______ that can process intensive tasks.

Accepted Answer

Grid computing links multiple individual computers to create a virtual supercomputer that can process intensive tasks. Therefore, option D, virtual supercomputer is the best choice. Options A, B, and C are incorrect as they do not accurately describe the concept of grid computing.

Question 16

What is the safe disposal of MIS assets at the end of their life cycle called?

Accepted Answer

Sustainable MIS (Management Information Systems) disposal refers to the environmentally responsible methods of disposing of MIS assets when they are no longer needed or have reached the end of their life cycle. This includes recycling, selling, or donating hardware and properly erasing data to protect sensitive information.

Question 17

With grid computing,a problem is broken into pieces and distributed to many machines,allowing _________ processing than could occur with a single system.

Accepted Answer

Grid computing allows for parallel processing, meaning that many machines can work on different pieces of a problem at the same time. This results in faster processing overall than could occur with a single system.

Question 18

What is a Platform as a Service (PaaS)?

Accepted Answer

Platform as a Service (PaaS) supports the deployment of entire systems including hardware, networking, and applications using a pay-per-use revenue model, making it the best choice among the given options. Set up and storage systems including servers and database management model, and Innovation and new develops new programs for business on an ongoing basis are not the correct definitions of PaaS. While Salesforce.com is an example of PaaS, it alone cannot define the entire concept of PaaS.

What service delivers hardware networking capabilities,including the use of servers,networking and storage over the cloud using a pay-per-use revenue model?

Accepted Answer

IaaS delivers hardware networking capabilities, including the use of servers, networking, and storage over the cloud, and uses a pay-per-use revenue model. Dynamic scaling refers to the ability to automatically adjust resources based on demand. SaaS delivers software applications over the cloud, and PaaS provides a platform for developers to build and deploy applications.

Question 20

What are the ramifications of improper electronic recycling,when analysing the example of a single desktop computer?

Accepted Answer

All the options are correct. Improper electronic recycling can have severe consequences as a single desktop computer contains more than 700 chemicals. These chemicals can contaminate our land, water, and air, resulting in long-term damage to the environment and human health. Computers contain high levels of mercury, lead, and cadmium, which are hazardous toxins. Hence, it is crucial to dispose of electronic devices in an appropriate way to minimize the impact on the environment and human health.
