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 is 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.

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 physical server failure
an Azure region failure
a storage failure
an Azure data center failure
Answer is 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.

This question requires that you evaluate the underlined text to determine if it is correct.
Resource groups provide organizations with the ability to manage the compliance of Azure resources across multiple subscriptions.
Instructions: Review the underlined text. If it makes the statement correct, select No change is needed. If the statement is incorrect, select the answer choice that makes the statement correct.
No change is needed
Management groups
Azure policies
Azure App Service plans
Answer is Azure policies
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 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?
multiple subscriptions
multiple Azure Active Directory (Azure AD) directories
multiple regions
multiple resource groups
Answers are multiple subscriptions
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 an Azure environment that contains multiple Azure virtual machines.
You plan to implement a solution that enables the client computers on your 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 virtual network gateway
a load balancer
an application gateway
a virtual network
a gateway subnet
Answers are; a virtual network gateway
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.

For each of the following statements, select Yes if the statement is true. Otherwise, select No.
Box 1: No
You can have 1 Account Administrator and 1 Service Administrator, but you can have 200 Co-Administrators per subscription
Box 2: No
You need an Azure Active Directory account to manage a subscription, not a Microsoft account. An account is created in the Azure Active Directory when you create the subscription. Further accounts can be created in the Azure Active Directory to manage the subscription.
Box 3: No
Resource groups are logical containers for Azure resources. However, resource groups do not contain subscriptions. Subscriptions contain resource groups.

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 resource group for FinServer and another resource group for all the other servers
a virtual network for FinServer and another virtual network for all the other servers
a VPN for FinServer and a virtual network gateway for each other server
one resource group for all the servers and a resource lock for FinServer
Answer is 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.

Your company plans to migrate all its network resources to Azure.
You need to start the planning process by exploring Azure.
What should you create first?
a subscription
a resource group
a virtual network
a management group
Answer is a subscription
The first thing you create in Azure is a subscription. You can think of an Azure subscription as an Azure account. You get billed per subscription.
A subscription is an agreement with Microsoft to use one or more Microsoft cloud platforms or services, for which charges accrue based on either a per-user license fee or on cloud-based resource consumption.
Microsoft's Software as a Service (SaaS)-based cloud offerings (Office 365, Intune/EMS, and Dynamics 365) charge per-user license fees.
Microsoft's Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) cloud offerings (Azure) charge based on cloud resource consumption.
You can also use a trial subscription, but the subscription expires after a specific amount of time or consumption charges. You can convert a trial subscription to a paid subscription.
Organizations can have multiple subscriptions for Microsoft's cloud offerings.
