51.In which type of cloud model are all the hardware resources owned by a third-party and shared between multiple tenants?

• private

• hybrid

• public

Answer explanation

Microsoft Azure, Amazon Web Services and Google Cloud are three examples of public cloud services.
Microsoft, Amazon and Google own the hardware. The tenants are the customers who use the public cloud services.

52.Select the answer that correctly completes the sentence:
... is a desktop and application virtualization service that enables the use of a cloud-hosted version of Windows from any lcation.

• An availability set

• Azure Spot Virtual Machines

• Azure Virtual Desktop

• Azure Virtual Machine Scale Sets

53.You have 1,000 virtual machines hosted on the Hyper-V hosts in a data center.
You plan to migrate all the virtual machines to an Azure pay-as-you-go subscription.
You need to identify which expenditure model to use for the planned Azure solution.
Which expenditure model should you identify?

• operational

• elastic

• capital

• scalable

Answer explanation

One of the major changes that you will face when you move from on-premises cloud to the public cloud is the switch from capital expenditure (buying hardware) to operating expenditure (paying for service as you use it). This switch also requires more careful management of your costs. The benefit of the cloud is that you can fundamentally and positively affect the cost of a service you use by merely shutting down or resizing it when it's not needed.

57.Your company has an on-premises network that contains multiple servers.
The company plans to reduce the following administrative responsibilities:
✑ Backing up application data
✑ Replacing failed server hardware
✑ Managing physical server security
✑ Updating server operating systems
✑ Managing permissions to shared documents
The company plans to migrate servers to Azure virtual machines.
You need to identify which administrative responsibilities will be eliminated after the planned migration.
Which two responsibilities should you identify? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.

• Replacing failed server hardware

• Backing up application data

• Managing physical server security

• Updating server operating systems

• Managing permissions to shared documents

Answer explanation

Azure virtual machines run on Hyper-V physical servers. The physical servers are owned and managed by Microsoft. As an Azure customer, you have no access to the physical servers. Microsoft manage the replacement of failed server hardware and the security of the physical servers so you don't need to.
Incorrect Answers:
B: Microsoft have no control over the applications you run on the virtual machines. Therefore, it is your responsibility to ensure that application data is backed up.
D: Microsoft do not manage the operating systems you run on the virtual machines. Therefore, it is your responsibility to ensure that the operating systems are updated.
E: Microsoft have no control over the shared folders you host on the virtual machines. Therefore, it is your responsibility to ensure that folder permissions are configured appropriately.

59.You plan to provision Infrastructure as a Service (IaaS) resources in Azure.
Which resource is an example of IaaS?

• an Azure web app

• an Azure virtual machine

• an Azure logic app

• an Azure SQL database

Answer explanation

An Azure virtual machine is an example of Infrastructure as a Service (IaaS).
Azure web app, Azure logic app and Azure SQL database are all examples of Platform as a Service (Paas).

60.To which cloud models can you deploy physical servers?

• private cloud and hybrid cloud only

• private cloud only

• private cloud, hybrid cloud and public cloud

• hybrid cloud only

Answer explanation

A private cloud is on-premises so you can deploy physical servers.
A hybrid cloud is a mix of on-premise and public cloud resources. You can deploy physical servers on-premises.

63.You have 50 virtual machines hosted on-premises and 50 virtual machines hosted in Azure. The on-premises virtual machines and the Azure virtual machines connect to each other.
Which type of cloud model is this?

• hybrid

• private

• public

65.Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
Your company plans to migrate all its data and resources to Azure.
The company's migration plan states that only Platform as a Service (PaaS) solutions must be used in Azure.
You need to deploy an Azure environment that meets the company migration plan.
Solution: You create Azure virtual machines, Azure SQL databases, and Azure Storage accounts.
Does this meet the goal?

• YES

• NO

Answer explanation

Platform as a service (PaaS) is a complete development and deployment environment in the cloud. PaaS includes infrastructure ג€" servers, storage, and networking ג€" but also middleware, development tools, business intelligence (BI) services, database management systems, and more. PaaS is designed to support the complete web application lifecycle: building, testing, deploying, managing, and updating.
However, virtual machines are examples of Infrastructure as a service (IaaS). IaaS is an instant computing infrastructure, provisioned and managed over the internet.

66.Your company plans to deploy several custom applications to Azure. The applications will provide invoicing services to the customers of the company. Each application will have several prerequisite applications and services installed.
You need to recommend a cloud deployment solution for all the applications.
What should you recommend?

• Software as a Service (SaaS)

• Platform as a Service (PaaS)

• Infrastructure as a Service (laaS)

72.complete the sentence:
You can assign a ... to every Azure resource.

• blueprint

• lock

• policy

• service endpoint

Answer explanation

You can assign a lock on every Azure resource that you have access to. You can apply a lock at different levels of scope: subscription, resource group, or individual resource.
