   1. HOTSPOT

      You plan to migrate App1 to Azure.

      You need to estimate the compute costs for App1 in Azure. The solution must meet the security and compliance requirements.

      What should you use to estimate the costs, and what should you implement to minimize the costs? To answer, select the appropriate options in the answer area.

      NOTE: Each correct selection is worth one point.

      

      

      Explanation:

      Box 1: The Azure Total Cost of Ownership (TCO) Calculator
      The Total Cost of Ownership (TCO) Calculator estimates the cost savings you can realize by migrating your workloads to Azure.

      Note: The TCO Calculator recommends a set of equivalent services in Azure that will support your applications. Our analysis will show each cost area with an estimate of your on-premises spend versus your spend in Azure. There are several cost categories that either decrease or go away completely when you move workloads to the cloud.

      Box 2: Azure Hybrid Benefit
      Azure Hybrid Benefit is a licensing benefit that helps you to significantly reduce the costs of running your workloads in the cloud. It works by letting you use your on-premises Software Assurance-enabled Windows Server and SQL Server licenses on Azure. And now, this benefit applies to RedHat and SUSE Linux subscriptions, too.

      Scenario:
      Litware identifies the following security and compliance requirements:

      – Once App1 is migrated to Azure, you must ensure that new data can be written to the app, and the modification of new and existing data is prevented for a period of three years.
      – On-premises users and services must be able to access the Azure Storage account that will host the data in App1.
      – Access to the public endpoint of the Azure Storage account that will host the App1 data must be prevented.
      – All Azure SQL databases in the production environment must have Transparent Data Encryption (TDE) enabled.
      – App1 must not share physical hardware with other workloads.

    – Once App1 is migrated to Azure, you must ensure that new data can be written to the app, and the modification of new and existing data is prevented for a period of three years.
    – On-premises users and services must be able to access the Azure Storage account that will host the data in App1.
    Access to the public endpoint of the Azure Storage account that will host the App1 data must be prevented.
    All Azure SQL databases in the production environment must have Transparent Data Encryption (TDE) enabled.
    App1 must not share physical hardware with other workloads.

    Planned Changes and Requirements. Business Requirements

    Litware identifies the following business requirements:

    – Minimize administrative effort.
    – Minimize costs.

    1. HOTSPOT

       You plan to migrate App1 to Azure.

       You need to recommend a storage solution for App1 that meets the security and compliance requirements.

       Which type of storage should you recommend, and how should you recommend configuring the storage? To answer, select the appropriate options in the answer area.

       NOTE: Each correct selection is worth one point.

       

       

       Explanation:

       Box 1: BlobStorage
       BlobStorage supports NFSv3, see below.

       Box 2: NFSv3
       Blob storage now supports the Network File System (NFS) 3.0 protocol. This support provides Linux file system compatibility at object storage scale and prices and enables Linux clients to mount a container in Blob storage from an Azure Virtual Machine (VM) or a computer on-premises.

       Scenario: Litware identifies the following security and compliance requirements:

       On-premises users and services must be able to access the Azure Storage account that will host the data in App1.

    2. You migrate App1 to Azure.

       You need to ensure that the data storage for App1 meets the security and compliance requirements.

       What should you do?

       • Create Azure RBAC assignments.
       • Create an access policy for the blob service.
       • Modify the access level of the blob service.
       • Implement Azure resource locks.
       Explanation:

       Azure Active Directory (Azure AD) authorizes access rights to secured resources through Azure role-based access control (Azure RBAC). Azure Storage defines a set of Azure built-in roles that encompass common sets of permissions used to access blob data.

       When an Azure role is assigned to an Azure AD security principal, Azure grants access to those resources for that security principal. An Azure AD security principal may be a user, a group, an application service principal, or a managed identity for Azure resources.

       Scenario:
       To access the resources in Azure, App1 must use the managed identity of the virtual machines that will host the app.

       The Litware.com tenant contains a custom Azure role-based access control (Azure RBAC) role named Role1 that grants the Data Actions read permission to the blobs and files in Azure Storage.

       Litware identifies the following security and compliance requirements:

       – On-premises users and services must be able to access the Azure Storage account that will host the data in App1.

    3. HOTSPOT

       You need to ensure that users managing the production environment are registered for Azure MFA and must authenticate by using Azure MFA when they sign in to the Azure portal. The solution must meet the authentication and authorization requirements.

       What should you do? To answer, select the appropriate options in the answer area.

       NOTE: Each correct selection is worth one point.

       

       

       Explanation:

       Box 1: Azure AD Identity Protection
       Azure AD Identity Protection helps you manage the roll-out of Azure AD Multi-Factor Authentication (MFA) registration by configuring a Conditional Access policy to require MFA registration no matter what modern authentication app you are signing in to.

       Scenario: Users that manage the production environment by using the Azure portal must connect from a hybrid Azure AD-joined device and authenticate by using Azure Multi-Factor Authentication (MFA).

       Box 2: Sign-in risk policy…
       Scenario: The Litware.com tenant has a conditional access policy named capolicy1. Capolicy1 requires that when users manage the Azure subscription for a production environment by using the Azure portal, they must connect from a hybrid Azure AD-joined device.

       Identity Protection policies we have two risk policies that we can enable in our directory.
       Sign-in risk policy
       User risk policy

    4. You plan to migrate App1 to Azure.

       You need to recommend a network connectivity solution for the Azure Storage account that will host the App1 data. The solution must meet the security and compliance requirements.

       What should you include in the recommendation?

       • a private endpoint
       • a service endpoint that has a service endpoint policy
       • Azure public peering for an ExpressRoute circuit
       • Microsoft peering for an ExpressRoute circuit
       Explanation:

       By default, Azure service resources secured to virtual networks aren’t reachable from on-premises networks. If you want to allow traffic from on-premises, you must also allow public (typically, NAT) IP addresses from your on-premises or ExpressRoute. You can add these IP addresses through the IP firewall configuration for Azure service resources.

       You can use ExpressRoute for public peering and Microsoft peering.

       Scenario:
       – On-premises users and services must be able to access the Azure Storage account that will host the data in App1.
       – Access to the public endpoint of the Azure Storage account that will host the App1 data must be prevented.

       Incorrect Answers:
       C: Public Peering is deprecated for new circuits.

    5. You plan to migrate App1 to Azure. The solution must meet the authentication and authorization requirements.

       Which type of endpoint should App1 use to obtain an access token?

       • Azure Instance Metadata Service (IMDS)
       • Azure AD
       • Azure Service Management
       • Microsoft identity platform
       Explanation:

       Scenario: To access the resources in Azure, App1 must use the managed identity of the virtual machines that will host the app.

       Managed identities provide an identity for applications to use when connecting to resources that support Azure Active Directory (Azure AD) authentication. Applications may use the managed identity to obtain Azure AD tokens.

    6. DRAG DROP

       You need to configure an Azure policy to ensure that the Azure SQL databases have TDE enabled. The solution must meet the security and compliance requirements.

       Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

       

       

       Explanation:

       Scenario: All Azure SQL databases in the production environment must have Transparent Data Encryption (TDE) enabled.

       Step 1: Create an Azure policy definition that uses the deployIfNotExists identity.
       The first step is to define the roles that deployIfNotExists and modify needs in the policy definition to successfully deploy the content of your included template.

       Step 2: Create an Azure policy assignment
       When creating an assignment using the portal, Azure Policy both generates the managed identity and grants it the roles defined in roleDefinitionIds.

       Step 3: Invoke a remediation task
       Resources that are non-compliant to a deployIfNotExists or modify policy can be put into a compliant state through Remediation. Remediation is accomplished by instructing Azure Policy to run the deployIfNotExists effect or the modify operations of the assigned policy on your existing resources and subscriptions, whether that assignment is to a management group, a subscription, a resource group, or an individual resource.

       During evaluation, the policy assignment with deployIfNotExists or modify effects determines if there are non-compliant resources or subscriptions. When non-compliant resources or subscriptions are found, the details are provided on the Remediation page.

    Overview

    Fabrikam, Inc. is an engineering company that has offices throughout Europe. The company has a main office in London and three branch offices in Amsterdam, Berlin, and Rome.

    Existing Environment. Active Directory Environment

    The network contains two Active Directory forests named corp.fabrikam.com and rd.fabrikam.com. There are no trust relationships between the forests.

    Corp.fabrikam.com is a production forest that contains identities used for internal user and computer authentication.

    Rd.fabrikam.com is used by the research and development (R&D) department only.

    Existing Environment. Network Infrastructure

    Each office contains at least one domain controller from the corp.fabrikam.com domain. The main office contains all the domain controllers for the rd.fabrikam.com forest.

    All the offices have a high-speed connection to the Internet.

    An existing application named WebApp1 is hosted in the data center of the London office. WebApp1 is used by customers to place and track orders. WebApp1 has a web tier that uses Microsoft Internet Information Services (IIS) and a database tier that runs Microsoft SQL Server 2016. The web tier and the database tier are deployed to virtual machines that run on Hyper-V.

    The IT department currently uses a separate Hyper-V environment to test updates to WebApp1.

    Fabrikam purchases all Microsoft licenses through a Microsoft Enterprise Agreement that includes Software Assurance.

    Existing Environment. Problem Statements

    The use of WebApp1 is unpredictable. At peak times, users often report delays. At other times, many resources for WebApp1 are underutilized.

    Requirements. Planned Changes

    Fabrikam plans to move most of its production workloads to Azure during the next few years.

    As one of its first projects, the company plans to establish a hybrid identity model, facilitating an upcoming Microsoft 365 deployment.

    All R&D operations will remain on-premises.

    Fabrikam plans to migrate the production and test instances of WebApp1 to Azure.

    Requirements. Technical Requirements

    Fabrikam identifies the following technical requirements:

    – Web site content must be easily updated from a single point.
    – User input must be minimized when provisioning new web app instances.
    – Whenever possible, existing on-premises licenses must be used to reduce cost.
    – Users must always authenticate by using their corp.fabrikam.com UPN identity.
    – Any new deployments to Azure must be redundant in case an Azure region fails.
    – Whenever possible, solutions must be deployed to Azure by using the Standard pricing tier of Azure App Service.
    – An email distribution group named IT Support must be notified of any issues relating to the directory synchronization services.
    – Directory synchronization between Azure Active Directory (Azure AD) and corp.fabrikam.com must not be affected by a link failure between Azure and the on-premises network.

    Requirements. Database Requirements

    Fabrikam identifies the following database requirements:

    – Database metrics for the production instance of WebApp1 must be available for analysis so that database administrators can optimize the performance settings.
    – To avoid disrupting customer access, database downtime must be minimized when databases are migrated.
    – Database backups must be retained for a minimum of seven years to meet compliance requirements.

    Requirements. Security Requirements

    Fabrikam identifies the following security requirements:

    – Company information including policies, templates, and data must be inaccessible to anyone outside the company.
    – Users on the on-premises network must be able to authenticate to corp.fabrikam.com if an Internet link fails.
    – Administrators must be able authenticate to the Azure portal by using their corp.fabrikam.com credentials.
    – All administrative access to the Azure portal must be secured by using multi-factor authentication.
    – The testing of WebApp1 updates must not be visible to anyone outside the company.

    1. What should you include in the identity management strategy to support the planned changes?

       • Move all the domain controllers from corp.fabrikam.com to virtual networks in Azure.
       • Deploy domain controllers for the rd.fabrikam.com forest to virtual networks in Azure.
       • Deploy domain controllers for corp.fabrikam.com to virtual networks in Azure.
       • Deploy a new Azure AD tenant for the authentication of new R&D projects.
       Explanation:
       Directory synchronization between Azure Active Directory (Azure AD) and corp.fabrikam.com must not be affected by a link failure between Azure and the on-premises network. (This requires domain controllers in Azure)
       Users on the on-premises network must be able to authenticate to corp.fabrikam.com if an Internet link fails. (This requires domain controllers on-premises)

    2. HOTSPOT

       To meet the authentication requirements of Fabrikam, what should you include in the solution? To answer, select the appropriate options in the answer area.

       NOTE: Each correct selection is worth one point.

       

       

       Explanation:

       Box 1: 2
       The network contains two Active Directory forests named corp.fabrikam.com and rd.fabrikam.com. There are no trust relationships between the forests.

       Box 2: 1

       Box 3: 1

       Scenario:
       – Users on the on-premises network must be able to authenticate to corp.fabrikam.com if an Internet link fails.
       – Administrators must be able authenticate to the Azure portal by using their corp.fabrikam.com credentials.
       – All administrative access to the Azure portal must be secured by using multi-factor authentication.

       Note:
       Users must always authenticate by using their corp.fabrikam.com UPN identity.
       The network contains two Active Directory forests named corp.fabrikam.com and rd.fabrikam.com. There are no trust relationships between the forests.

       Corp.fabrikam.com is a production forest that contains identities used for internal user and computer authentication.

       Rd.fabrikam.com is used by the research and development (R&D) department only.

18. You are designing an Azure resource deployment that will use Azure Resource Manager templates. The deployment will use Azure Key Vault to store secrets.

    You need to recommend a solution to meet the following requirements:

    – Prevent the IT staff that will perform the deployment from retrieving the secrets directly from Key Vault.
    – Use the principle of least privilege.

    Which two actions should you recommend? Each correct answer presents part of the solution.

    NOTE: Each correct selection is worth one point.

    • Create a Key Vault access policy that allows all get key permissions, get secret permissions, and get certificate permissions.
    • From Access policies in Key Vault, enable access to the Azure Resource Manager for template deployment.
    • Create a Key Vault access policy that allows all list key permissions, list secret permissions, and list certificate permissions.
    • Assign the IT staff a custom role that includes the Microsoft.KeyVault/Vaults/Deploy/Action permission.
    • Assign the Key Vault Contributor role to the IT staff.
    Explanation:

    B: To access a key vault during template deployment, set enabledForTemplateDeployment on the key vault to true.

    D: The user who deploys the template must have the Microsoft.KeyVault/vaults/deploy/action permission for the scope of the resource group and key vault.

    Incorrect Answers:
    E: To grant access to a user to manage key vaults, you assign a predefined key vault Contributor role to the user at a specific scope.
    If a user has Contributor permissions to a key vault management plane, the user can grant themselves access to the data plane by setting a Key Vault access policy. You should tightly control who has Contributor role access to your key vaults. Ensure that only authorized persons can access and manage your key vaults, keys, secrets, and certificates.

19. You have an Azure subscription that contains web apps in three Azure regions.

    You need to implement Azure Key Vault to meet the following requirements:

    – In the event of a regional outage, all keys must be readable.
    – All the web apps in the subscription must be able to access Key Vault.
    – The number of Key Vault resources to be deployed and managed must be minimized.

    How many instances of Key Vault should you implement?

    • 1
    • 2
    • 3
    • 6
    Explanation:

    The contents of your key vault are replicated within the region and to a secondary region at least 150 miles away but within the same geography. This maintains high durability of your keys and secrets. See the Azure paired regions document for details on specific region pairs.

    Example: Secrets that must be shared by your application in both Europe West and Europe North. Minimize these as much as you can. Put these in a key vault in either of the two regions. Use the same URI from both regions. Microsoft will fail over the Key Vault service internally.

20. You have an Azure Active Directory (Azure AD) tenant.

    You plan to provide users with access to shared files by using Azure Storage. The users will be provided with different levels of access to various Azure file shares based on their user account or their group membership.

    You need to recommend which additional Azure services must be used to support the planned deployment.

    What should you include in the recommendation?

    • an Azure AD enterprise application
    • Azure Information Protection
    • an Azure AD Domain Services (Azure AD DS) instance
    • an Azure Front Door instance
    Explanation:
    Azure Files supports identity-based authentication over Server Message Block (SMB) through two types of Domain Services: on-premises Active Directory Domain Services (AD DS) and Azure Active Directory Domain Services (Azure AD DS).
