AZ-900 Sample QuestionsQuestion 1. A company has an on-premises network containing several servers. The company plans to migrate all the servers to Azure. John has been asked to provide a solution to make sure that some of the servers are available in case a single Azure data center goes offline for an extended period. What must John do in this case?
Correct Answer: Fault Tolerance Explanation: Fault tolerance is the property that allows a system to continue operating properly in the event of the failure of (or one or more faults within) some of its components. The Availability Zones expand the level of control for maintaining the availability of the applications and data on the Virtual Machines. The physical separation of Availability Zones within a region safeguards applications and data from data center failures. Moreover, with Availability Zones, Azure offers an uptime of 99.99% for Virtual Machines SLA. Therefore, by architecting solutions to use replicated Virtual Machines in zones, we can protect the applications and data from the loss of a data center. Refer: Availability options for Azure Virtual Machines Question2: When we implement a Software as a Service (SaaS)solution, then we become responsible to ________________.
Correct Answer: Configure the SaaS Solution Explanation: While implementing a Software as a Service (SaaS) solution, you become responsible to configure the SaaS solution. SaaS needs the least amount of management as the cloud provider is responsible to manage everything, allowing the end-user to use the software smoothly. Moreover, Software as a service (SaaS) permits the users to connect to and use cloud-based apps over the Internet like email, calendaring and office tools. Reference: What is SaaS? and Azure Fundamental Concepts Question 3: A company that hosts its infrastructure in _________________________ does not require its own data center.
Correct Answer: Public Cloud Explanation: A company that hosts its infrastructure in a public cloud can close its data centre. The public cloud is one of the most common deployment models. In this case, there is no need to manage local hardware or keep it updated since everything runs on the cloud provider’s hardware. On the other hand, a private cloud is hosted in your own data centre. Therefore, you cannot close your data centre if you are using a private cloud. Reference: Different types of Cloud Models Question 4. Which of the following are the characteristics of the public cloud?(A) Dedicated hardware
Correct Answer: Only (D) and (E) Explanation: Azure Cloud service offers metered pricing, as we pay for the resources being used. Also, public cloud services offer a self-managed service, as you can use the portal to add, change and also remove the resources as and when needed. Since hardware is shared among public cloud clients, so it is not dedicated. Therefore, connections on the cloud are secured. Also, storage is virtually unlimited on the cloud and in the public cloud, you get pay-as-you-go pricing with no CapEx costs. Also, the public cloud offers self-service management services. Refer: Types of Cloud Models Question 5: What should you do when planning to migrate a public website to Azure?
Correct Answer: Paying monthly usage cost Explanation: In order to migrate to a cloud platform there are some key features to consider when using Azure Websites as your hosting solution. Like it should be globally available, should have a built-in load balancer and more. Reference: How to plan your migration to Azure Website Question 6: An organization intends to migrate all its data and resources to Azure. The migration plan developed requires that only Platform as a Service (PaaS) solutions must be used in Azure. John has been asked to deploy an Azure environment that meets the requirement of the migration plan. John suggests creating an Azure App Service and Azure SQL databases. Does the suggested solution meet the requirement?
Correct Answer: Azure App Service and Azure SQL databases are illustrations of Azure PaaS solutions. Thus, the suggested solution meets the requirement. Reference: SQL Database PaaS Overview Question7: An organization plans to host an accounting application called App1 that will be used by all the customers of the organization. It was observed that App1 had low usage during the initial three weeks of each month and very high usage during the last week of each month. Which of the following advantages of Azure Cloud Services will support cost management to handle this kind of usage pattern?
Correct Answer: Elasticity Explanation: Elasticity offers the ability to provide additional compute resources when needed and reduce them when not required for reducing the costs. One of the examples of elasticity is Autoscaling. Elastic computing provides the ability to quickly expand or decrease computer processing, memory and storage resources to meet changing demands without worrying about capacity planning and engineering for peak usage. Moreover, cloud elasticity offers an organization to not pay for any unused capacity or unused resources. References: About Elastic Computing Question 8: An organization plans to migrate a web application to Azure that can be accessed by external users. Peter has been asked to suggest a cloud deployment solution for minimizing the amount of administrative effort in managing the web application. Which of the following should Peter include in the solution to meet the requirement?
Correct Answer: Platform as a Service (PaaS) Explanation: Since, Azure App Service is a platform-as-a-service (PaaS) that allows you to create web and mobile apps for any platform/device and then connect it to data anywhere, in the cloud or on-premises. Also, App Service includes the web and mobile capabilities that were previously delivered separately as Azure Websites and Azure Mobile Services. Reference: PaaS Application using App Service Question 9: Which of the given cloud deployment solution is suggested for Azure virtual machines?
Correct Answer: Infrastructure as a Service (IaaS) Explanation: Azure virtual machines are Infrastructure as a Service (IaaS) which is the most flexible category of cloud services. IaaS aims to offer a complete control over the hardware that runs the application including IT infrastructure servers, virtual machines, storage, networks, and operating systems. Therefore rather than buying hardware, with IaaS, we rent it. Reference: Principles of Cloud Computing Question 10: 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?
Correct Answer: Hybrid Cloud Explanation: A hybrid cloud is a combination of a private cloud and a public cloud. Capital expenditure involves spending money up-front for infrastructure like new servers. Also, with a hybrid cloud, we can use the on-premises servers while adding new servers in the public cloud. Moreover, adding new servers in Azure reduces the capital expenditure costs as we will not be paying for new servers which could have been the case if we deployed new server on-premises. Reference: https://docs.microsoft.com/en-gb/learn/modules/principles-cloud-computing/4-cloud-deployment-models Question 11: An organization is planning to migrate several servers from an on-premises network to Azure. Which of the following is a benefit of using a public cloud service for the servers over an on-premises network?
Correct Answer: Public cloud is a shared entity whereby multiple corporations each use a portion of the resources in the cloud Explanation: Since, the public cloud is a shared entity where multiple corporations can use a portion of the resources in the cloud. Also, the hardware resources (servers, infrastructure etc.) are managed by the cloud service provider. Multiple organization are now building resources such as virtual machines (VMs) and virtual networks on the hardware resources. Question 12: In which of the given kind of cloud model are all the hardware resources owned by a third party and shared between multiple tenants?
Correct Answer: Public Cloud Explanation: Microsoft Azure, Amazon Web Services (AWS) and Google Cloud are some of the examples of public cloud service providers. Microsoft, Amazon and Google own the hardware. The tenants are the customers who use the public cloud services. Question13: An organization has 1,000 virtual machines (VMs) hosted on the Hyper-V hosts in a data center. They are planning to migrate all the virtual machines to an Azure pay-as-you-go subscription. John has been asked to suggest the expenditure model to use for the planned Azure solution. Which of the given expenditure model should he choose in this case?
Correct Answer: Operational Explanation: The most significant change that will be face when moving from an on-premises cloud to a public cloud is the switch from capital expenditure (i.e, buying hardware) to operating expenditure (paying for service). Also, this shift requires more careful management of costs and expenditures. The primary advantage of the cloud is that you can positively impact the cost of a service you use by merely shutting down or resizing it when not required Reference: Microsoft Cloud Adoption Framework for Azure Question 14: State whether the following statement holds True or False. “A company deploying its own data center is an example of CapEx.”
Correct Answer: Yes, the statement is correct Explanation: Deploying your own datacenter is an example of CapEx since it is required to purchase all the infrastructure upfront before it can be used. Reference: Microsoft Cloud Adoption Framework for Azure Question 15: A company plans to offer Infrastructure as a Service (IaaS) resources in Azure. Which of the following resources is an example of Infrastructure as a Service (IaaS)?
Correct Answer: Azure virtual machine Explanation: An Azure virtual machine is an example of Infrastructure as a Service (IaaS). On the other hand, Azure web app, Azure logic app and Azure SQL database are all examples of Platform as a Service (Paas). Reference: Introduction to IaaS and What is PaaS Question 16: On which of the following cloud models can we deploy physical servers?
Correct Answer: Private cloud and Hybrid cloud only Explanation: Since a private cloud is on-premises therefore we can deploy physical servers. Also, Aa hybrid cloud is a mix of on-premise and public cloud resources. So, we can deploy physical servers on-premises. Reference: Introduction to Hybrid Cloud Question 17: A company has 50 Virtual Machines (VMs) hosted on-premises and 50 Virtual Machines (VMs) hosted in Azure. The Azure virtual machines and on-premises virtual machines connect to each other. Which of the following type of cloud model does this represent?
