reboot that like button by turning into white now here's your Compton instructor to walk you through the questions question one which of the following statements is true regarding virtualization a virtualization requires specialized Hardware B virtualization is used only for Server consolidation C virtualization provides isolation and flexibility in running multiple operating systems on a single physical machine D virtualization is used only for data backup and Recovery the correct answer is C virtualization provides isolation and flexibility in running multiple operating systems on a single physical machine virtualization allows multiple operating systems to run on a single physical machine providing isolation and flexibility question two which of the following is a characteristic of cloud computing a on-premises hosting B shared resources c local storage D limited scalability 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 thank you for watching this video we hope you enjoyed it check out these videos that can help you
