If it makes the statement correct, select "No change is needed". a. No change is needed b. Management groups c. Azure plicies d. Azure App Service plans

C Azure policies can be used to define requirements for resource properties during deployment and for already existing resources. Azure Policy controls properties such as the types or locations of resources. Azure Policy is a service in Azure that you use to create, assign, and manage policies. These policies enforce different rules and effects over your resources, so those resources stay compliant with your corporate standards and service level agreements. Azure Policy meets this need by evaluating your resources for non- compliance with assigned policies. All data stored by Azure Policy is encrypted at rest. For example, you can have a policy to allow only a certain SKU size of virtual machines in your environment. Once this policy is implemented, new and existing resources are evaluated for compliance. With the right type of policy, existing resources can be brought into compliance.

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 an Azure App Service and Azure Storage accounts. Does this meet the goal?

Yes / No You can use Availability Zones in Azure to protect Azure virtual machines from a region failure. Yes / No You can use Availability Zones in Azure to protect Azure managed disks from a datacenter failure. Yes / No

Yes, No, Yes 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.

Azure Pay-As-You-Go pricing is an example CapEx. Yes / No Azure Reserved VM instances are an example of OpEx. Yes / No Deploying your own datacenter is an example of CapEx. Yes / No

No, No, Yes Box 1: No -With the pay-as-go model, you pay for services as you use them. This is Opex (Operational Expenditure), not CapEx (Captial Expenditure). CapEx is where you pay for something upfront. For example, buying a new physical server.Box 2: No -A reserved instance is where you pay upfront for the use of a virtual machine for a period of time (1 or 3 years). This can save you money as you receive a discount on the cost of a VM if you pay upfront for a reserved instance. However, as this is an upfront payment, it will be classed as CapEx, not OpEx.Box 3: Yes -Deploying your own datacenter is an example of CapEx. This is because you need to purchase all the infrastructure upfront before you can use it.

To achieve a hybrid cloud model, a company must always migrate from a private cloud. Yes / No A company can extend the capacity of its internal network by using the public cloud. Yes / No In a public cloud model, only guest users at your company can access the resources in the cloud. Yes / No

No, Yes, No Box 1: No - It is not true that a company must always migrate from a private cloud model to implement a hybrid cloud. You could start with a public cloud and then combine that with an on-premise infrastructure to implement a hybrid cloud. Box 2: Yes - A company can extend the capacity of its internal network by using the public cloud. This is very common. When you need more capacity, rather than pay out for new on-premises infrastructure, you can configure a cloud environment and connect your on-premises network to the cloud environment by using a VPN. Box 3: No - It is not true that only guest users can access cloud resources. You can give anyone with an account in Azure Active Directory access to the cloud resources. There are many authentication scenarios but a common one is to replicate your on-premises Active Directory accounts to Azure Active Directory and provide access to the Azure Active Directory accounts. Another commonly used authentication method is where authentication for access to cloud resources is passed to another authentication provider such as an on-premises Active Directory.

An Azure subscription can be associated to multiple Azure Active Directory (Azure AD) tenants. Yes / No You can change the Azure Active Directory (Azure AD) tenant to which an Azure subscription is associated. Yes / No When an Azure subscription expires, the associated Azure Active Directory (Azure AD) tenant is deleted automatically. Yes / No

No, Yes, No Box 1: No -An Azure AD tenant can have multiple subscriptions but an Azure subscription can only be associated with one Azure AD tenant. Box 2: Yes Box 3: No -If your subscription expires, you lose access to all the other resources associated with the subscription. However, the Azure AD directory remains in Azure. You can associate and manage the directory using a different Azure subscription.

To implement a hybrid cloud model, a company must first have a private cloud. Yes / No A company can extend the computing resources of its internal network by using a hybrid cloud. Yes / No In a public cloud model, only guest users at your company can access the resources in the cloud. Yes / No

No, Yes, No Box 1: No -It is not true that a company must always migrate from a private cloud model or must first have a private cloud to implement a hybrid cloud. You could start with a public cloud and then combine that with an on-premise infrastructure to implement a hybrid cloud. Box 2: Yes -A company can extend the computing resources of its internal network by using the public cloud. This is very common. When you need more resources, rather than pay out for new on-premises infrastructure, you can configure a cloud environment and connect your on-premises network to the cloud environment by using a VPN. Box 3: No -It is not true that only guest users can access cloud resources. You can give anyone with an account in Azure Active Directory access to the cloud resources. There are many authentication scenarios but a common one is to replicate your on-premises Active Directory accounts to Azure Active Directory and provide access to the Azure Active Directory accounts. Another commonly used authentication method is ג€˜Federationג€™ where authentication for access to cloud resources is passed to another authentication provider such as an on-premises Active Directory.

A company can extend a private cloud by adding its own physical servers to the public cloud. Yes / No To build a hybrid cloud, you must deploy resources to the public cloud. Yes / No A private cloud must be disconnected from the internet. Yes / No

No, Yes, No Box 1: No -You cannot add physical servers to the public cloud. You can only deploy virtual servers in the public cloud. You can extend a private cloud by deploying virtual servers in a public cloud. This would create a hybrid cloud. Box 2: Yes -A hybrid cloud is a combination of a private cloud and public cloud. Therefore, to create a hybrid cloud, you must deploy resources to a public cloud. Box 3: No. It is not true that a private cloud must be disconnected from the Internet. Private clouds can be and most commonly are connected to the Internet. ג€Private cloudג€ means that the physical servers are managed by you. It does not mean that it is disconnected from the Internet.

Yes / No A Platform as a Service (PaaS) solution that hosts web apps in Azure can be configured to automatically scale the number of instances based on demand. Yes / No

No, Yes, Yes Box 1: No -A PaaS solution does not provide access to the operating system. The Azure Web Apps service provides an environment for you to host your web applications. Behind the scenes, the web apps are hosted on virtual machines running IIS. However, you have no direct access to the virtual machine, the operating system or IIS. Box 2: Yes Box 3: Yes -A PaaS solution that hosts web apps in Azure does provide the ability to scale the platform automatically. This is known as autoscaling. Behind the scenes, the web apps are hosted on virtual machines running IIS. Autoscaling means adding more load balanced virtual machines to host the web apps.

Azure resources can only access other resources in the same resource group. Yes / No If you delete a resource group, all the resources in the resource group will be deleted. Yes / No A resource group can contain resources from multiple Azure regions. Yes / No

No, Yes, Yes Box 1: No -A resource can interact with resources in other resource groups. Box 2: Yes -Deleting the resource group will remove the resource group as well as all the resources in that resource group. This can be useful for the management of resources. For example, a virtual machine has several components (the VM itself, virtual disks, network adapter etc.). By placing the VM in its own resource group, you can delete the VM along with all its associated components by deleting the resource group. Another example is when creating a test environment. You could place the entire test environment (Network components, virtual machines etc.) in one resource group. You can then delete the entire test environment by deleting the resource group. Box 3: Yes -Resources from multiple different regions can be placed in a resource group. The resource group only contains metadata about the resources it contains.

A single Microsoft account can be used to manage multiple Azure subscriptions. Yes / No Two Azure subscriptions can be merged into a single subscription. Yes / No A company can use resources from multiple subscriptions. Yes / No

Yes, No, Yes Box 1: Yes -You can use the same account to manage multiple subscriptions. You can create an additional subscription for your account in the Azure portal. You may want an additional subscription to avoid hitting subscription limits, to create separate environments for security, or to isolate data for compliance reasons. Box 2: No -You cannot merge two subscriptions into a single subscription. However, you can move some Azure resources from one subscription to another. You can also transfer ownership of a subscription and change the billing type for a subscription. Box 3: Yes -A company can have multiple subscriptions and store resources in the different subscriptions. However, a resource instance can exist in only one subscription.

You plan to store 20 TB of data in Azure. The data will be accessed infrequently and visualized by using Microsoft Power BI/ You need to recommend a storage solution for the data. Which two solutions should you recommend? a. Azure Data Lake b. Azure Cosmos DB c. Azure SQL Data Warehouse d. Azure SQL Database e. Azure Database for PostgreSQL

a. Azure Data Lake c. Azure SQL Data Warehouse You can use Power BI to analyze and visualize data stored in Azure Data Lake and Azure SQL Data Warehouse. Azure Data Lake includes all of the capabilities required to make it easy for developers, data scientists and analysts to store data of any size and shape and at any speed, and do all types of processing and analytics across platforms and languages. It removes the complexities of ingesting and storing all your data while making it faster to get up and running with batch, streaming and interactive analytics. It also integrates seamlessly with operational stores and data warehouses so that you can extend current data applications.

Which cloud deployment solution is used for Azure virtual machines and Azure SQL databases? Azure virtual machines: a. IaaS b. PaaS c. SaaS Azure SQL database: a. IaaS b. PaaS c. SaaS

a. IaaS b. PaaS Box 1: Azure virtual machines are Infrastructure as a Service (IaaS).Infrastructure as a Service is the most flexible category of cloud services. It aims to give you complete control over the hardware that runs your application (IT infrastructure servers and virtual machines (VMs), storage, networks, and operating systems). Instead of buying hardware, with IaaS, you rent it. Box 2: Azure SQL databases are Platform as a Service (PaaS).Azure SQL Database is a fully managed Platform as a Service (PaaS) Database Engine that handles most of the database management functions such as upgrading, patching, backups, and monitoring without user involvement. Azure SQL Database is always running on the latest stable version of SQL Server Database Engine and patched OS with 99.99% availability. PaaS capabilities that are built-in into Azure SQL database enable you to focus on the domain specific database administration and optimization activities that are critical for your business.

Your company has an on-premises network that contains multiple servers. The company plans to reduce the following administrative responsibilities of network administrators: - Backing up applications data - Replacing failed server hardware - Managing physical server hardware - Updating server operating systems - Managing permissions to shared documents The company plans to migrate several 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. a. Replacing failed server hardware b. Backing up application data c. Managing physical server security d. Updating server operating systems e. Managing permissions to shared documents

a. Replacing failed server hardware d. Updating server operating systems 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. 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.

you plan to deploy several Azure virtual machines. You need to ensure that the services running on the virtual machines are available if a single data center fails. Solution: You deploy the virtual machines to two or more availability zones. Does this meet the goal? a. Yes b. No

a. Yes 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.

You plan to deploy several Azure virtual machines. You need to ensure that the services running on the virtual machines are available if a single data center fails. Solution: You deploy the virtual machines to two or more regions. Does this meet the goal? a. Yes b. No

a. Yes By deploying the virtual machines to two or more regions, you are deploying the virtual machines to multiple datacenters. This will ensure that the services running on the virtual machines are available if a single data center fails .Azure operates in multiple datacenters around the world. These datacenters are grouped in to geographic regions, giving you flexibility in choosing where to build your applications. You create Azure resources in defined geographic regions like 'West US', 'North Europe', or 'Southeast Asia'. You can review the list of regions and their locations. Within each region, multiple datacenters exist to provide for redundancy and availability.

You have an Azure environment that contains multiple Azure virtual machines. You plan to implement a solution that enables the client computers on you on-premises network to communicate to the Azure virtual machines. You need to recommend which Azure resources must be created for the planned solution. Which two Azure resources should you include in the recommendation? a. a virtual network gateway b. a load balancer c. an application gateway d. a virtual network e. a gateway subnet

a. a virtual network gateway e. a gateway subnet To implement a solution that enables the client computers on your on-premises network to communicate to the Azure virtual machines, you need to configure a VPN (Virtual Private Network) to connect the on-premises network to the Azure virtual network. The Azure VPN device is known as a Virtual Network Gateway. The virtual network gateway needs to be located in a dedicated subnet in the Azure virtual network. This dedicated subnet is known as a gateway subnet and must be named "GatewaySubnet". Note: a virtual network (answer D) is also required. However, as we already have virtual machines deployed in a Azure, we can assume that the virtual network is already in place.

You plan to deploy 20 virtual machines to an Azure environment. To ensure that a virtual machine named VM1 cannot connect to the other virtual machines, VM1 must ________________. a. be deployed to a separate virtual network. b. run a different operating system that the other virtual machines. c. be deployed to a separate resource group. d. have two network interface.

a. be deployed to a separate virtual network. Azure automatically routes traffic between subnets in a virtual network. Therefore, all virtual machines in a virtual network can connect to the other virtual machines in the same virtual network. Even if the virtual machines are on separate subnets within the virtual network, they can still communicate with each other. To ensure that a virtual machine cannot connect to the other virtual machines, the virtual machine must be deployed to a separate virtual network.

Azure Site Recovery provides __________ for virtual machines. a. fault tolerance b. disaster recovery c. elasticity d. high availability

a. fault tolerance Azure Site Recovery helps ensure business continuity by keeping business apps and workloads running during outages. Site Recovery replicates workloads running on physical and virtual machines (VMs) from a primary site to a secondary location.

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 an Azure virtual machines, Azure SQL databases, and Azure Storage accounts. Does this meet the goal? a. Yes b. No

b. No 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.

Your company plans to migrate to Azure. The company has several departments. All the Azure resources used by each department will be managed by a department administrator. What are two possible techniques to segment Azure for the departments? a. multiple subscriptions b. multiple Azure Active Directory (Azure AD) directories c. multiple regions d. multiple resource groups

a. multiple subscriptions d. multiple resource groups An Azure subscription is a container for Azure resources. It is also a boundary for permissions to resources and for billing. You are charged monthly for all resources in a subscription. A single Azure tenant (Azure Active Directory) can contain multiple Azure subscriptions. A resource group is a container that holds related resources for an Azure solution. The resource group can include all the resources for the solution, or only those resources that you want to manage as a group. To enable each department administrator to manage the Azure resources used by that department, you will need to create a separate subscription per department. You can then assign each department administrator as an administrator for the subscription to enable them to manage all resources in that subscription.

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

To which cloud models can you deploy physical servers? a. private cloud and hybrid cloud only b. private cloud only c. private cloud, hybrid cloud and public cloud d. hybrid cloud only

a. private cloud and hybrid cloud only 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.

You plan to deploy several Azure virtual machines. You need to ensure that the services running on the virtual machines are available if a single data center fails. Solution: You deploy the virtual machines to two or more resource groups. Does this meet the goal? a. Yes b. No

b. No A resource group is a logical container for Azure resources. When you create a resource group, you specify which location to create the resource group in. However, when you create a virtual machine and place it in the resource group, the virtual machine can still be in a different location (different datacenter).Therefore, creating multiple resource groups, even if they are in separate datacenters does not ensure that the services running on the virtual machines are available if a single data center fails.

You plan to deploy several Azure virtual machines. You need to ensure that the services running on the virtual machines are available if a single data center fails. a. Yes b. No

b. No This answer does not specify that the scale set will be configured across multiple data centers so this solution does not meet the goal. Azure virtual machine scale sets let you create and manage a group of load balanced VMs. The number of VM instances can automatically increase or decrease in response to demand or a defined schedule. Scale sets provide high availability to your applications, and allow you to centrally manage, configure, and update many VMs. Virtual machines in a scale set can be deployed across multiple update domains and fault domains to maximize availability and resilience to outages due to data center outages, and planned or unplanned maintenance events.

Software as a Service (SaaS) b. Platform as a Service (PaaS) c. Infrastructure as a Service (IaaS) d. Database as a Service (DaaS)

b. Platform as a Service (PaaS) Azure App Service is a platform-as-a-service (PaaS) offering that lets you create web and mobile apps for any platform or device and connect to data anywhere, in the cloud or on-premises. App Service includes the web and mobile capabilities that were previously delivered separately as Azure Websites and Azure Mobile Services.

Your company plans to move several servers to Azure. The company's compliance policy states that a server named FinServer must be on a separate network segment. You are evaluating which Azure services can be used to meet the compliance policy requirements. Which Azure solution should you recommend? a. a resource group for FinServer and another resource group for all the other servers b. a virtual network for FinServer and another virtual network for all the other servers c. a VPN for FinServer and a virtual network gateway for each other server d. one resources group for all the servers and a resource lock for FinServer

b. a virtual network for FinServer and another virtual network for all the other servers Networks in Azure are known as virtual networks. A virtual network can have multiple IP address spaces and multiple subnets. Azure automatically routes traffic between different subnets within a virtual network. The question states that FinServer must be on a separate network segment. The only way to separate FinServer from the other servers in networking terms is to place the server in a different virtual network to the other servers.

You plan to provision Infrastructure as a Service (IaaS) resources in Azure. Which resource is an example of IaaS? a. an Azure web app b. an Azure virtual machine c. an Azure logic app d. an Azure SQL database

b. pay monthly usage costs.

Your company plans to deploy several custom applications to Azure. The applications will provide invoicing 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? a. Software as a Service (SaaS) b. Platform as a Service (PaaS) c. Infrastructure as a Service (IaaS)

c. Infrastructure as a Service (IaaS) Infrastructure as a service (IaaS) is an instant computing infrastructure, provisioned and managed over the internet. The IaaS service provider manages the infrastructure, while you purchase, install, configure, and manage your own software. A: 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. In this scenario, you need to run your own apps, and therefore require an infrastructure. B:Platform as a service (PaaS) is a complete development and deployment environment in the cloud. PaaS includes infrastructureג€"servers, storage, and networkingג€"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.

You plan to map a network drive from several computers that run Windows 10 to Azure Storage. You need to create a storage solution in Azure for the planned mapped drive. What should you create? a. an Azure SQL database b. a virtual machine data disk c. a Files service in a storage account d. a Blobs service in a storage account

c. a Files service in a storage account Azure Files is Microsoft's easy-to-use cloud file system. Azure file shares can be seamlessly used in Windows and Windows Server. To use an Azure file share with Windows, you must either mount it, which means assigning it a drive letter or mount point path, or access it via its UNC path. Unlike other SMB shares you may have interacted with, such as those hosted on a Windows Server, Linux Samba server, or NAS device, Azure file shares do not currently support Kerberos authentication with your Active Directory (AD) or Azure Active Directory (AAD) identity, although this is a feature we are working on. Instead, you must access your Azure file share with the storage account key for the storage account containing your Azure file share. A storage account key is an administrator key for a storage account, including administrator permissions to all files and folders within the file share you're accessing, and for all file shares and other storage resources (blobs, queues, tables, etc.) contained within your storage account.

Your company hosts an accounting application named App1 that is used by all the customers of the company.App1 has low usage during the first three weeks of each month and very high usage during the last week of each month. Which benefit of Azure Cloud Services supports cost management for this type of usage pattern? a. high availability b. high latency c. elasticity d. load balancing

c. elasticity Elasticity in this case is the ability to provide additional compute resource when needed and reduce the compute resource when not needed to reduce costs. Autoscaling is an example of elasticity. Elastic computing is 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. Typically controlled by system monitoring tools, elastic computing matches the amount of resources allocated to the amount of resources actually needed without disrupting operations. With cloud elasticity, a company avoids paying for unused capacity or idle resources and doesnג€™t have to worry about investing in the purchase or maintenance of additional resources and equipment.

An organization that hosts its infrastructure _________ no longer requires a data center. a. in a private cloud b. in a hybrid cloud c. in the public cloud d. on a Hyper-V host

c. in a public cloud

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.

When you need to delegate permissions to several Azure virtual machines simultaneously, you must deploy the Azure virtual machines ___________. a. to the same Azure region. b. by using the same Azure Resource Manager template. c. to the same resource group. d. to the same availability zone.

c. to the same resource group. A resource group is a logical container for Azure resources. Resource groups make the management of Azure resources easier. With a resource group, you can allow a user to manage all resources in the resource group, such as virtual machines, websites, and subnets. The permissions you apply to the resource group apply to all resources contained in the resource group.

You attempt to create several managed Microsoft SQL Server instances in an Azure environment and receive a message that you must increase you Azure subscription limits. What should yo do to increase the limits? a. Create a service health alert b. Upgrade your support plan c. Modify an Azure plicy d. Create a new support request

d. Create a new support request Many Azure resource have quote limits. The purpose of the quota limits is to help you control your Azure costs. However, it is common to require an increase to the default quota. You can request a quota limit increase by opening a support request. In the support request, select "Service and subscription limits (quotas)" for the Issue type, select your subscription and the service you want to increase the quota for. For this question, you would select "SQL Database Managed Instance" as the quote type.

You plan to migrate several servers from an on-premises network to Azure. What is an advantage of using a public cloud service for the servers over an on-premises network? a. The public cloud is owned by the public, NOT a private corporation b. The public cloud is a crowd-sourcing solution that provides corporations with the ability to enhance the cloud c. All public cloud resources can be freely accessed by every member of the public d. The public cloud is a shared entity where multiple corporations each use a portion of the resources in the cloud

d. The public cloud is a shared entity whereby multiple corporations each use a portion of the resources in the cloud Box 1: No -It is not true that a company must always migrate from a private cloud model to implement a hybrid cloud. You could start with a public cloud and then combine that with an on-premise infrastructure to implement a hybrid cloud. Box 2: Yes -A company can extend the capacity of its internal network by using the public cloud. This is very common. When you need more capacity, rather than pay out for new on-premises infrastructure, you can configure a cloud environment and connect your on-premises network to the cloud environment by using a VPN. Box 3: No -It is not true that only guest users can access cloud resources. You can give anyone with an account in Azure Active Directory access to the cloud resources. There are many authentication scenarios but a common one is to replicate your on-premises Active Directory accounts to Azure Active Directory and provide access to the Azure Active Directory accounts. Another commonly used authentication method is where authentication for access to cloud resources is passed to another authentication provider such as an on-premises Active Directory.

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.

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. hybrid 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. Incorrect Answers: A: A complete migration of 100 servers to the public cloud would involve a lot of operational expenditure (the cost of migrating all the servers). B: An additional data center would involve a lot of capital expenditure (the cost of the new infrastructure). C: A private cloud is hosted on on-premises servers to this would involve a lot of capital expenditure (the cost of the new infrastructure to host the private cloud).
