the correct answer is B shared resources

cloud computing is characterized by the

use of shared resources which allows for

efficient use of resources and cost

savings

question 3 which of the following is an

example of a public cloud service

a Amazon web services AWS B Microsoft

Exchange Server C VMware vsphere D

Oracle database the correct answer is a

Amazon web services AWS

public cloud services are offered by

third-party providers such as AWS and

are accessible over the internet

question 4 which of the following is a

benefit of cloud computing a limited

scalability B reduce data security C

reduced capital expenditure D increased

Hardware requirements the correct answer

is C reduced capital expenditure

cloud computing allows organizations to

reduce their capital expenditure by

eliminating the need to purchase and

maintain on-premises Hardware

question 5 which of the following is a

disadvantage of cloud computing

a limited scalability b reduced

flexibility C increased Hardware

requirements D dependence on the

internet the correct answer is D

dependence on the internet

cloud computing relies on the internet

for access to services and data which

can be a disadvantage if internet

connectivity is poor or unreliable

question 6 which of the following is an

example of a private cloud service

a Google Cloud platform B Microsoft

azure

C Salesforce D VMware Cloud Foundation

the correct answer is D VMware Cloud

Foundation

private cloud services are hosted within

an organization's own infrastructure

such as VMware Cloud Foundation

question seven which of the following is

a benefit of virtualization

a increased Hardware requirements B

limited scalability C reduced power

consumption D increased data security

the correct answer is C reduced power

consumption

virtualization allows organizations to

run multiple virtual machines on a

single physical machine reducing power

consumption and improving Energy

Efficiency

question 8 which of the following is a

disadvantage of virtualization

a limited scalability B increased

Hardware requirements C increased power

consumption D reduced data security the

correct answer is B increased Hardware

requirements

virtualization requires additional

Hardware resources to support the

virtual machines which can increase

Hardware requirements

question 9 which of the following is a

characteristic of a hybrid Cloud

environment a hosted entirely on

premises B uses only public cloud

services C uses both public and private

cloud services D hosts entirely in a

public Cloud environment the correct

answer is C uses both public and private

cloud services

a hybrid Cloud environment combines the

use of public and private cloud services

question 10 which of the following is a

benefit of a hybrid Cloud environment

A reduced data security B limited

scalability C increased flexibility D

reduced Hardware requirements the

correct answer is C increased

flexibility

a hybrid Cloud environment provides

greater flexibility by allowing

organizations to choose the most

appropriate cloud service for a given

workload or application

11 which of the following is an example

of a hypervisor

a Amazon web services AWS B Microsoft

hyper-v C Google Cloud platform D

Salesforce the correct answer is B

Microsoft hyper-v

a hypervisor also known as a virtual

machine monitor is software that allows

multiple virtual machines to run on a

single physical machine Microsoft

hyper-v is an example of a hypervisor

question 12 which of the following is a

benefit of cloud storage A reduced data

accessibility

B increased data security C reduce data

storage capacity D increased Hardware

requirements

the correct answer is B increased data

security

cloud storage provides increased data

security by storing data in off-site

locations and providing encryption and

access control features

question 13 which of the following is a

disadvantage of cloud storage

a increased data accessibility B reduce

data security C increased data storage

capacity D reduced Hardware requirements

the correct answer is a increased data

accessibility

cloud storage can provide increased data

accessibility but it also increases the

risk of unauthorized access or data

breaches

question 14 which of the following is a

characteristic of software as a service

saas

a allows for customization of software

applications B provides direct access to

Hardware resources C offers a

pay-per-use Model D requires specialized

Hardware

the correct answer is C offers a

pay-per-use model

saas allows users to access software

applications over the internet on a

subscription basis typically using a

pay-per-use model

question 15 which of the following is a

characteristic of platform as a surface

paas

a provides direct access to Hardware

resources B requires specialized

Hardware C allows for customization of

software applications D offers a

pre-configured environment for

application development and deployment

the correct answer is D offers a

pre-configured environment for

application development and deployment

paas provides a pre-configured

environment for application development

and deployment allowing developers to

focus on the application rather than the

underlying infrastructure

question 16 which of the following is a

characteristic of infrastructure as a

service iaas

a allows for customization of software

applications B offers a pre-configured

environment for application development

and deployment

C provides direct access to Hardware

resources D requires specialized

Hardware the correct answer is C

provides direct access to Hardware

resources

iaas provides access to virtualized

Hardware resources such as servers and

storage over the internet

question 17 which of the following is a

benefit of server virtualization

a increased Hardware requirements b

reduced power consumption

C reduce data security D increased

capital expenditure

the correct answer is b reduced power

consumption

server utilization allows organizations

to run multiple virtual servers on a

single physical machine reducing power

consumption and improving Energy

Efficiency

question 18 which of the following is a

disadvantage of server virtualization

a increased Hardware requirements b

reduced power consumption C increased

data security D increased capital

expenditure the correct answer is a

increased Hardware requirements

server virtualization requires

additional Hardware resources to support

the virtual servers which can increase

Hardware requirements

question 19 which of the following is an

example of a public cloud storage

service

a Amazon S3 B Google Cloud Storage C

Microsoft OneDrive D Dropbox the correct

answer is a Amazon S3

Amazon S3 is an example of a public

cloud storage service which allows users

to store and retrieve data over the

internet

question 20 which of the following is a

benefit of cloud backup and Recovery a

increased data accessibility B reduce

data security C reduced Hardware

requirements D improved data recovery

times the correct answer is D improved

data recovery times

cloud backup and Recovery can improve

data recovery Times by providing

off-site data backups and Rapid data

restoration
