Cloud Technology MCQ Quiz - Objective Question with Answer for Cloud Technology - Download Free PDF

The correct answer is Reduces the amount of physical hardware used

Key Points

• Virtualization allows multiple virtual machines (VMs) to run on a single physical server, enabling better resource utilization.
• This consolidation of workloads onto fewer physical servers can lead to a reduction in the overall number of servers needed in a data center.
• Fewer physical servers mean less power consumption, reduced cooling requirements, and a smaller physical footprint.
• This results in lower energy consumption and a more efficient use of resources, contributing to environmental sustainability and the principles of Green Computing.

Key Points 

The essential characteristics of cloud computing are:

• On-demand self-service: Users can provision computing resources, such as server time and network storage, as needed automatically without requiring human interaction with each service's provider.
• Broad network access: Capabilities are available over the network and accessed through standard devices (e.g., a smartphone, tablet, laptop, or workstation).
• Resource pooling: The provider's computing resources are pooled to serve multiple customers with different physical and virtual resources dynamically assigned and reassigned according to customer demand.
• Rapid elasticity: Resources can be rapidly and elastically provisioned, in some cases automatically, to scale quickly outward and inward commensurate with demand (e.g., the ability to quickly scale to handle a large number of users during a peak period).
• Measured service: Cloud systems automatically control and optimize resource use by metering resource use (e.g., by the amount of storage used).

Fixed pricing is not an essential characteristic of cloud computing. Some cloud providers offer fixed pricing plans, but others offer pay-as-you-go pricing plans.

Therefore, the answer is (1).

The correct answer is Cloud computing.

Key Points

• Cloud computing refers to the delivery of computing services such as servers, storage, databases, networking, software, analytics, and intelligence over the Internet (the cloud) to offer faster innovation, flexible resources, and economies of scale.
• Cloud computing allows users to access and store data and applications on remote servers, and then access all the data via the Internet.
• It eliminates the capital expense of buying hardware and software and setting up and running on-site data centers.
• Cloud computing offers three main types of services: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

Additional Information

• Distributing Computing
  • Distributed computing refers to multiple computer systems working on a single problem. This model divides tasks into smaller tasks that are distributed across several computers.
  • It involves the use of a network of computers to perform tasks that require more computing power than a single computer could provide.
  • Examples include grid computing and blockchain technology.
• Soft Computing
  • Soft computing is a computing paradigm that deals with approximate models and gives solutions to complex real-life problems.
  • It encompasses techniques like fuzzy logic, neural networks, evolutionary computation, and probabilistic reasoning.
  • Soft computing is used in areas where traditional computing methods cannot efficiently solve problems, such as pattern recognition, data mining, and artificial intelligence.
• Parallel Computing
  • Parallel computing is a type of computation in which many calculations or processes are carried out simultaneously.
  • Large problems can often be divided into smaller ones, which can then be solved at the same time.
  • It is used in high-performance computing environments to solve complex scientific and engineering problems.

• Meta (formerly known as Facebook) is a technology company that does not offer a cloud platform. They focus on social networking services and products related to virtual reality.
• One Drive is a cloud storage service developed by Microsoft that allows users to store files and personal data like Windows settings or BitLocker recovery keys in the cloud.
• Dropbox is a file hosting service that offers cloud storage, file synchronization, personal cloud, and client software. It is not a comprehensive cloud platform like AWS.

• Amazon Elastic Compute Cloud (Amazon EC2) provides scalable computing capacity in the Amazon Web Services (AWS) cloud.
• Using Amazon EC2 eliminates user need to invest in hardware up front, so he can develop and deploy applications faster.
• User can use Amazon EC2 to launch as many or as few virtual servers as you need, configure security and networking, and manage storage. Amazon EC2 enables you to scale up or down to handle changes in requirements or spikes in popularity, reducing your need to forecast traffic.
• Infrastructure as a Service (IaaS) provides virtualize computing resources over the internet and hence EC2 is IaaS

The correct answer is option 2, i.e. Platform as a Service.

• Cloud platform services, also known as Platform as a Service (PaaS), provide cloud components to certain software while being used mainly for applications.
• PaaS delivers a framework for developers that they can build upon and use to create customized applications.
• All servers, storage, and networking can be managed by the enterprise or a third-party provider while the developers can maintain management of the applications.
• Examples: AWS Elastic Beanstalk, Windows Azure, Heroku, Force.com, Google App Engine, Apache Stratos, OpenShift

The correct answer is option 4.

Key PointsVirtualization uses software to create an abstraction layer over computer hardware that allows the hardware elements of a single computer processor, memory, storage, and more to be divided into multiple virtual computers, commonly called virtual machines (VMs). Each VM runs its own operating system (OS) and behaves like an independent computer, even though it is running on just a portion of the actual underlying computer hardware.

It is a technology that lets you create useful IT services using resources that are traditionally bound to hardware. It allows you to use a physical machine's full capacity by distributing its capabilities among many users or environments. It's the same hardware, you're just using more of it more efficiently.

Hence the correct answer is Virtualization.

Additional Information

• A storage area network (SAN) is a dedicated, independent high-speed network that interconnects and delivers shared pools of storage devices to multiple servers. Each server can access shared storage as if it were a drive directly attached to the server. Each switch and storage system on the SAN must be interconnected.
• Clustering is the task of dividing the population or data points into a number of groups such that data points in the same groups are more similar to other data points in the same group than those in other groups. In simple words, the aim is to segregate groups with similar traits and assign them into clusters.
• Artificial intelligence (AI) is the ability of a computer or a robot controlled by a computer to do tasks that are usually done by humans because they require human intelligence and discernment.

Concept:

Cloud computing provides a flexible environment to use resources at low cost. Cloud computing is a web based, distributed computing using which information, resources and software are distributed among different users. All the resources are on web, so this is the reason that there come various ways to provide services.

Explanation:

Cloud computing is internet-based computing where customers do not own the physical infrastructure. All services are on internet. Various services in cloud computing model are as follows:

SaaS – It stands for software as a service. In this, application is hosted as a service to customers who access it via internet. It provides packaged business process offerings that live in cloud. In this, cloud contains stack such as operating system, application software etc.

IaaS – It stands for infrastructure as a service. It is responsible for providing virtualized computing resources, network resources with IaaS users assemble their own virtual cluster on which they are responsible for installing, maintaining, and executing their own software stack.

PaaS – It stands for platform as a service. It supplies all the resources required to build applications and services completely by using internet without having to download or install software. It includes application design, development and hosting. 

The correct option is It is a type of Internet-based computing that provides shared computer processing resources and data to computers and other devices on demand
