Has increased administrative complexity C. Has the same configuration options as on-premises D. Shifts capital expenditures (CAPEX) to operating expenditures (OPEX)

A. Enables the rapid provisioning of resources D. Shifts capital expenditures (CAPEX) to operating expenditures (OPEX) Azure allows you to build, deploy, and manage apps more quickly and easily without having to buy and/or maintain the underlying infrastructure. Azure provides flexibility between CapEx and OpEx Capital expenditures generate benefits over a long period. These expenditures are generally nonrecurring and result in the acquisition of permanent assets. Building an application could qualify as a capital expenditure. Example, Azure Reserved Instances (Azure RI) help Azure's most active customers save on long- term VM usage reserving VMs in advance at a discounted price by committing to a one or three-year benefits. Operating expenditures are ongoing costs of doing business. Consuming cloud services in a pay-as-you-go model could qualify as an operating expenditure. Example, you pay for a service or product as you use it i.e. pay-as-you-go pricing.

#37 You have an on-premises network that contains several servers. You plan to migrate all the servers to Azure. You need to recommend a solution to ensure that some of the servers are available if a single Azure data center goes offline for an extended period. What should you include in the recommendation? A. Fault tolerance B. Elasticity C. Scalability D. Low latency

A. Fault tolerance Fault tolerance is the ability of a system to continue to function in the event of a failure of some of its components. In this question, you could have servers that are replicated across datacenters. Availability zones expand the level of control you have to maintain the availability of the applications and data on your VMs. Availability Zones are unique physical locations within an Azure region. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking. To ensure resiliency, there are a minimum of three separate zones in all enabled regions. The physical separation of Availability Zones within a region protects applications and data from datacenter failures. With Availability Zones, Azure offers industry best 99.99% VM uptime SLA. By architecting your solutions to use replicated VMs in zones, you can protect your applications and data from the loss of a datacenter. If one zone is compromised, then replicated apps and data are instantly available in another zone.

#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? A. Operational B. Elastic C. Capital D. Scalable

A. Operational 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.

#68 Complete the sentence: Azure Cosmos DB is an example of a ...... offering. A. Platform as a Service (PaaS) B. Infrastructure as a Service (IaaS) C. Serverless D. Software as a Service (SaaS)

Platform as a Service (PaaS) Box: Platform as a service (PaaS) Platform as a service (PaaS) is a complete development and deployment environment in the cloud, with resources that enable you to deliver everything from simple cloud-based apps to sophisticated, cloud-enabled enterprise applications. You purchase the resources you need from a cloud service provider on a pay- as-you-go basis and access them over a secure Internet connection. Like IaaS, PaaS includes infrastructureג€"servers, storage, and networkingג€"but also middleware, development tools, business intelligence (BI) services, database management systems, and more.

#51 In which type of cloud model are all the hardware resources owned by a third-party and shared between multiple tenants? A. Private B. Hybrid C. Public

C. Public 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.

#47 You have an on-premises network that contains 100 servers. You need to recommend a solution that provides additional resources to your users. The solution must minimize capital and operational expenditure costs. What should you include in the recommendation? A. A complete migration to the public cloud B. An additional data center C. A private cloud D. A hybrid cloud

D. A hybrid cloud A hybrid cloud is a combination of a private cloud and a public cloud. Capital expenditure is the spending of money up-front for infrastructure such as new servers. With a hybrid cloud, you can continue to use the on-premises servers while adding new servers in the public cloud (Azure for example). Adding new servers in Azure minimizes the capital expenditure costs as you are not paying for new servers as you would if you deployed new server on-premises.

#96 You need to identify the type of failure for which an Azure Availability Zone can be used to protect access to Azure services. What should you identify? A. A physical server failure B. An Azure region failure C. A storage failure D. An Azure data center failure

D. An Azure data center failure Availability zones expand the level of control you have to maintain the availability of the applications and data on your VMs. An Availability Zone is a physically separate zone, within an Azure region. There are three Availability Zones per supported Azure region. Each Availability Zone has a distinct power source, network, and cooling. By architecting your solutions to use replicated VMs in zones, you can protect your apps and data from the loss of a datacenter. If one zone is compromised, then replicated apps and data are instantly available in another zone.

#36 Complete the sentence: When you are implementing a Software as a Service (SaaS) solution, you are responsible for: A. Configuring high availability B. Defining scalability rules C. Installing the SaaS solution D. Configuring the SaaS solution

D. Configuring the SaaS solution When you are implementing a Software as a Service (SaaS) solution, you are responsible for configuring the SaaS solution. Everything else is managed by the cloud provider. SaaS requires the least amount of management. The cloud provider is responsible for managing everything, and the end user just uses the software. Software as a service (SaaS) allows users to connect to and use cloud-based apps over the Internet. Common examples are email, calendaring and office tools (such as Microsoft Office 365). SaaS provides a complete software solution which you purchase on a pay-as-you-go basis from a cloud service provider. You rent the use of an app for your organization and your users connect to it over the Internet, usually with a web browser. All of the underlying infrastructure, middleware, app software and app data are located in the service provider's data center. The service provider manages the hardware and software and with the appropriate service agreement, will ensure the availability and the security of the app and your data as well.
