Microsoft AZ-800 Administering Windows Server Hybrid Core Infrastructure Exam Practice Test

The Administering Windows Server Hybrid Core Infrastructure materials explain that Azure AD Password Protection for on-premises AD uses two components: the DC agent and the proxy service. The DC agent is installed on every domain controller because it “intercepts password set/change operations locally on the DC and evaluates them against the forbidden-password policy.” The guidance further states that to ensure consistent enforcement “the DC agent should be deployed to all DCs in the forest, since password changes may occur on any DC.” The proxy service is installed on member servers (not necessarily DCs) and “relays policy downloads and telemetry to Azure AD on behalf of DCs,” which satisfies environments where “domain controllers must not directly contact Internet endpoints.” Finally, configuration of the global and custom banned password lists is performed in Azure AD, where administrators “define tenant-wide custom banned terms; DCs obtain the policy via the proxy and cache it for local enforcement.”

Given Fabrikam’s requirement to prevent DCs from accessing the Internet, the proxy must run on non-DC servers (VM1 and VM2). To guarantee enforcement wherever a password is changed, the DC agent must be on all domain controllers. The custom banned password list is configured in the Azure AD tenant and then distributed to on-premises DCs via the proxy.

In Azure File Sync architecture (covered in Administering Windows Server Hybrid Core Infrastructure under “Implement and manage storage solutions”), the fundamental design points are:

Sync group – “A sync group defines a sync topology. Each sync group contains exactly one cloud endpoint (an Azure file share) and one or more server endpoints.” A server endpoint is a folder on a registered Windows Server. A server can participate in multiple sync groups so long as the server endpoints are different paths.

Storage Sync Service – “The Storage Sync Service is the top-level resource that maintains server registrations and houses your sync groups.” A Windows Server registers to one Storage Sync Service at a time, and that service can contain many sync groups and many servers.

Applying these rules to the requirement:

You have three Azure file shares: newyorkfiles, seattlefiles, and companyfiles. Because each sync group maps to one cloud endpoint, you need one sync group per share ⇒ 3 sync groups.

FS1 must sync with newyorkfiles and companyfiles; FS2 must sync with seattlefiles and companyfiles. Since one Storage Sync Service can host multiple sync groups and multiple servers, and a server must be registered to a single service, the most efficient design is a single Storage Sync Service containing all three sync groups and both servers.

The exam materials for Administering Windows Server Hybrid Core Infrastructure explain that when replacing private WAN links with Azure, Azure Virtual WAN (vWAN) can be used to centralize connectivity. For private connectivity, ExpressRoute integrates directly with a vWAN hub by deploying an ExpressRoute gateway in the hub. The gateway is the Azure resource that terminates ExpressRoute and enables hub-and-spoke routing to connected VNets (such as Vnet1). The guides emphasize: “In a Virtual WAN hub, use the ExpressRoute gateway to connect ExpressRoute circuits and propagate routes across the hub to your virtual networks.”

On-premises, each site (New York and Seattle) requires an ExpressRoute circuit connection provisioned via a connectivity provider. The circuit is the dedicated private connection from the customer edge to Microsoft’s edge and is what the office sites actually use; it’s then linked to the vWAN hub’s ExpressRoute gateway. The same materials note that Site-to-Site VPN is an alternative transport but is not required when ExpressRoute is mandated. Likewise, Application Gateway is a Layer-7 load balancer for HTTP/S traffic, and on-premises data gateway relates to Power BI/Power Platform hybrid connectivity, neither of which establishes network transport between offices and Azure.

Therefore, to meet the requirement “connect both on-premises offices to Vnet1 by using ExpressRoute,” configure an ExpressRoute gateway on the vWAN hub and ExpressRoute circuit connections in the offices.

The exam content for Group Policy processing stresses User Group Policy loopback processing for session hosts (RDS/AVD): “In environments like Remote Desktop Session Host (or Azure Virtual Desktop), enable loopback processing on the OU that contains the session host computers so that user settings from that GPO apply when users log on to those computers, regardless of the user’s own OU.” The requirement states: “Apply GPO4 to the Azure Virtual Desktop session hosts. Ensure that Azure Virtual Desktop user sessions lock after being idle for 10 minutes. Users must be able to control the lockout time manually from their client computer.” The idle-lock is a user configuration setting that must apply when users sign in to the session hosts, not to their personal devices. Therefore, enable loopback processing (Merge/Replace) in GPO4, which is linked to the VirtualDesktops OU containing the session hosts. Using security filtering or Enforced cannot make user settings in GPO4 override the user’s own OU without loopback. Loopback ensures the AVD hosts impose the 10-minute lock for sessions, while leaving users free to set their own client device policies independently—fulfilling least-impact design.

In the Administering Windows Server Hybrid Core Infrastructure guidance for extending AD DS into Azure, Microsoft states that when you place a domain controller in an Azure virtual network you must run DNS on that domain controller and point the VNet to that DNS server: “Domain controllers in Azure IaaS should host the AD-integrated DNS zone, and the virtual network’s DNS server setting must reference those DC/DNS IPs so Azure VMs use AD DNS rather than the Azure-provided resolver.” The materials also emphasize that Azure’s default DNS cannot host or manage AD DS zones, so custom DNS is required for domain-joined workloads. Therefore, to meet the requirement you (1) install the DNS Server role on DC3 so it can host the corp.fabrikam.com AD-integrated zone (F), and (2) configure the DNS Servers setting on Vnet1 to the IP of DC3 (and any additional DCs), ensuring all Azure VMs in Vnet1 resolve the domain via AD DNS (D). Creating a public Azure DNS zone or a Private DNS zone with the same AD name is not appropriate for AD-integrated name resolution. This design also supports the security requirement of preventing domain controllers from relying on Internet-facing resolvers.

In Administering Windows Server Hybrid Core Infrastructure, Microsoft states that high availability for DHCP on Windows Server is achieved by using DHCP failover rather than the legacy split-scope (80/20) model. The guidance explains that DHCP failover “synchronizes lease data between two DHCP servers and can be configured in Load Balance or Hot Standby mode on a per-scope basis,” and that you enable it on each DHCP scope to create a partner relationship that automatically replicates scope configuration and active leases. This meets the requirement to keep address assignment available if one DHCP server is down.

The same materials further note that DHCP broadcasts do not traverse routers; therefore, when the partner server is reachable across a routed boundary (another site/subnet), you must configure the router as a DHCP relay (IP helper) to forward DHCPDISCOVER messages to the remote DHCP server(s). The text emphasizes: “When clients and DHCP servers are on different subnets, configure a relay agent on the router to forward requests to the DHCP server IP addresses.”

Applying this to Fabrikam: create DHCP failover between DHCP1 (Scope1) and DHCP2 (Scope2) (E) and configure the routers in New York and Seattle as DHCP relays that forward to both DHCP servers (B). You do not use Failover Clustering for DHCP here, and you do not create extra 25% scopes; those are split-scope practices superseded by DHCP failover.

The exam materials explain that to add a new domain controller to an existing AD DS forest in Azure, you deploy a Windows Server IaaS VM and then promote it: “To extend on-premises AD DS into Azure, provision a Windows Server VM in Azure and run AD DS to create an additional domain controller for the existing domain.” Conversely, Azure Active Directory Domain Services (Azure AD DS) provides a managed domain that is separate from and not writable by your on-premises administrators—you “do not get domain admin rights or access to DCs”—so it cannot be used to add a DC (dc3.corp.fabrikam.com) to the existing corp.fabrikam.com forest. Azure AD Application Proxy and Azure AD administrative units are unrelated to deploying DCs. Therefore, the correct implementation is to deploy an Azure virtual machine in Vnet1, install AD DS/DNS, and promote it to become DC3 in the existing domain.

Within the hybrid governance section of Administering Windows Server Hybrid Core Infrastructure, Microsoft specifies that Azure Arc–enabled servers are the mechanism to bring on-premises and multi-cloud servers under Azure control to apply Azure Policy (Guest Configuration) and Defender for Servers. The prerequisite is installing the Azure Connected Machine agent (Azure Arc agent) on each server: “To manage servers with Azure Policy and configuration management, install the Connected Machine agent to onboard them to Azure Arc; once connected, you can assign Azure Policy guest configuration and monitor compliance just like Azure VMs.” Hybrid Azure AD Join is unrelated to Azure Policy assignment; the Azure Monitor agent provides telemetry but does not onboard to Arc for policy governance; a hybrid runbook worker is for Automation runbooks, not for enforcing Azure Policy. Therefore, to “use Azure Policy to enforce configuration management policies on the servers in Azure and on-premises,” deploy the Azure Connected Machine agent to all servers to Arc-enable them and then assign the desired policies.

In the Administering Windows Server Hybrid Core Infrastructure materials (AZ-800), Microsoft explains that Group Managed Service Accounts (gMSAs) are designed for services running on multiple servers and “provide automatic password management, simplified SPN management, and the ability to delegate the management to other administrators.” The guidance further states that before you can create any gMSA, “the domain must have a KDS root key so that the Key Distribution Service can generate and rotate strong, unique passwords for gMSAs on a schedule.” After the KDS root key is created, “use New-ADServiceAccount to create the gMSA and grant the computers (e.g., web servers) permission to retrieve the account password.” For IIS, the course notes specify that a gMSA can be used for app pools: “Configure the IIS application pool identity to a custom account and specify the gMSA name (ending with ‘$’) without a password; the password is managed automatically by AD and rotates by policy (for example, every 30 days).”

Mapping these requirements to the scenario: Webapp1 runs on WEB1 and WEB2 and must use the same service account with an automatic 30-day password change. Therefore, the correct sequence is: create the KDS root key, create the gMSA, and then set the IIS application pool to run under that account. This fulfills the security requirement while allowing both web servers to share the same, automatically-rotated credentials.

In the Administering Windows Server Hybrid Core Infrastructure materials (hybrid security and IaaS management), Just-In-Time (JIT) VM access from Microsoft Defender for Cloud is the prescribed way to require approval-based, time-bound Remote Desktop access to Azure VMs. The guide explains that JIT “locks down inbound traffic to management ports (for example, TCP/3389) and opens them only on request, for a limited time and only from approved source IPs.” Administrators request access; upon approval, Defender for Cloud creates a temporary NSG rule that expires automatically—you specify the maximum allowed window (e.g., 2 hours) and the ports. This matches the requirement: “Ensure that server administrators request approval before they can establish a Remote Desktop connection to an Azure virtual machine. If the request is approved, the connection must be established within two hours.” Alternatives don’t meet this: PIM governs Azure roles, not VM RDP port exposure; Azure Bastion provides secure RDP/SSH over TLS without public IPs but doesn’t provide approval/time-boxed gating; the Remote Desktop extension is for classic Cloud Services and not for policy-driven approval windows. JIT is the least-privilege, policy-enforced solution aligned with the exam’s hybrid security objectives.

In the Windows Server exam materials for Administering Windows Server Hybrid Core Infrastructure (AZ-800), Microsoft documents that Data Deduplication is supported only on data volumes and specifically on NTFS-formatted volumes, and it cannot be enabled on the system or boot volume. The study text states: “Data Deduplication is applied at the volume level and supports NTFS data volumes. You cannot enable deduplication on the system or boot volume.” It further clarifies unsupported targets: “ReFS volumes and FAT/exFAT volumes are not supported for Data Deduplication in general-purpose server scenarios,” and emphasizes that deduplication is “not available for the operating system volume.”

Applying these rules to VM3:

C: NTFS but it is the OS/system volume → not eligible.

D: NTFS data volume → eligible.

E: ReFS → not supported for general-purpose dedup in this context.

F: exFAT → not supported.

Therefore, the only volume on which you can enable Data Deduplication to meet the requirement is volume D.

In the Administering Windows Server Hybrid Core Infrastructure objectives for managing Hyper-V, enabling nested virtualization is the required step when you must “run virtual machines inside a virtual machine.” The referenced guidance states that Hyper-V on a VM is supported only when the host exposes hardware virtualization features to the guest. The prescriptive step is: “Turn off the VM and run Set-VMProcessor -VMName <VMName> -ExposeVirtualizationExtensions $true to enable nested virtualization.” The module further notes that this action “passes through Intel VT-x/AMD-V to the guest so the guest OS can install the Hyper-V role and create VMs.” It also clarifies that “the setting is applied on the parent host for the target VM and requires the VM to be powered off before the change is committed.”

Because the technical requirement says “Ensure that you can run virtual machines on VM1”, VM1 must be able to host Hyper-V while itself running as a VM on Server2. The first and essential cmdlet is therefore Set-VMProcessor with the -ExposeVirtualizationExtensions switch set to $true against VM1. Other optional settings (for example, MAC spoofing on the vNIC or static memory) may be configured later if needed, but exposing virtualization extensions is the enabling prerequisite that satisfies the requirement.

No

Yes

Yes

In Administering Windows Server Hybrid Core Infrastructure, Microsoft states that the domain password policy for domain user accounts is determined by the GPO that wins at the domain root (commonly the Default Domain Policy). GPOs linked to OUs do not change the domain password policy for user accounts in those OUs; they only affect local accounts on computers within those OUs unless Fine-Grained Password Policies (PSOs) are used and scoped to users/groups. The case shows Default Domain Policy in contoso.com sets Minimum password length = 10. Therefore, both Admin1 (a domain user in Contoso\OU1) and User1 (in Contoso\OU3) fall under the 10-character minimum; the OU-linked GPO1 (14) does not override the domain password policy for their domain accounts → Admin1: No, User1: Yes.

For member servers and local accounts, the documentation explains that password policy settings in a GPO linked to the OU containing the computer apply to that computer’s local Security Accounts Manager (SAM). In the scenario, Server1 resides in Member Servers and GPO2 linked to Member Servers specifies Minimum password length = 8. Thus, when Admin1 creates a local account on Server1, the enforced minimum is 8 characters → Yes. This approach follows least privilege and standard precedence: domain-level for domain accounts, OU-linked GPOs for local accounts, unless PSOs are explicitly defined.

The AZ-800 content covering Active Directory Sites and Services clarifies that site, subnet, and site-link objects live in the Configuration partition. The guides emphasize that administration of the Configuration naming context is restricted to Enterprise Admins and to Domain Admins of the forest-root domain. In the context of changing replication topology parameters—such as editing the replication schedule on site links—the documentation notes: “Only Enterprise Admins or administrators in the forest-root Domain Admins group have default permissions to modify site and site-link objects,” because these objects affect replication forest-wide.

Applying this to the scenario:

Contoso\Admin1 (Enterprise Admins) has forest-wide rights to modify site links.

Contoso\Admin2 (Domain Admins in contoso.com, the forest-root domain) also has the required rights to change site-link schedules.

Canada\Admin3 (Domain Admins in canada.contoso.com) does not have default permissions in the Configuration partition for forest-wide site-link administration.

Thus, to meet the technical requirement to change all site links to a 30-minute schedule, the users who can perform the task are Admin1 and Admin2.

n the Administering Windows Server Hybrid Core Infrastructure guidance for managing AD DS, Microsoft emphasizes using OU-level delegation to satisfy administrative needs while adhering to the principle of least privilege. The documentation explains that the Delegate Control wizard on an OU lets you grant a user or group only the specific permissions required for common tasks, including “Modify the membership of a group”. This grants the write permission to the member attribute on group objects contained in that OU, without giving broader account-management rights across the domain.

By contrast, placing a user in Account Operators or Server Operators provides elevated, domain-wide capabilities far beyond what is required. Account Operators can create, delete, and modify many account types across the domain (except for protected admin accounts), which violates least-privilege for a task that only needs to change group membership in one OU. Server Operators is unrelated to group membership and is intended for server administration tasks. Creating a delegation at the domain root would similarly be excessive because it applies broadly to all containers and OUs.

Therefore, to meet the requirement “Ensure that User1 can manage the membership of all the groups in Contoso\OU3,” you should delegate control on OU3 and assign the built-in task “Modify the membership of a group” to User1, achieving the minimal permissions necessary.

In Windows Server AD DS, group scope determines which groups/accounts can be members. The AZ-800 study materials summarize: “Domain Local groups can include accounts, Global groups, and Universal groups from any domain and Domain Local groups from the same domain only. Global groups can include accounts and other Global groups from the same domain only. Universal groups can include *accounts, Global groups, and Universal groups from any domain.” In addition, distribution vs. security does not change the scope membership rules; it only affects whether the group can be assigned permissions.

Applying the rules: Group3 is a Domain Local security group in contoso.com. Therefore it can contain Universal (Group1), Global from any domain (Group2 in contoso.com and Group4/Group5 in canada.contoso.com), but cannot contain a Domain Local from another domain (Group6 in canada.contoso.com). Hence: Group1, Group2, Group4, and Group5 only.

Group5 is a Global distribution group in canada.contoso.com. A Global group can only contain accounts or Global groups from the same domain. From the list, only Group4 (Global distribution, canada.contoso.com) fits. It cannot contain Group1 (Universal), Group2 (Global but different domain), or Group6 (Domain Local). Therefore: Group4 only.

One possible solution to ensure that a DHCP scope named scope1 on SRV1 can service client requests is to activate the scope on the DHCP server. A scope must be activated before it can assign IP addresses to DHCP clients. To activate a DHCP scope on SRV1, perform the following steps:

On SRV1, open DNS Manager from the Administrative Tools menu or by typing dnsmgmt.msc in the Run box.

In the left pane, expand your DHCP server and click on IPv4.

In the right pane, right-click on the scope that you want to activate, such as scope1, and select Activate.

Wait for the scope to be activated. You can verify the activation status by checking the icon next to the scope name. A green arrow indicates that the scope is active, while a red arrow indicates that the scope is inactive.

Now, the DHCP scope named scope1 on SRV1 can service client requests and lease IP addresses to DHCP clients. You can test the DHCP service by using the ipconfig /renew command on a DHCP client computer that is connected to the same subnet as the scope.

To create a group-managed service account (gMSA) named gMSA1 and make it available on SRV1, you can follow these steps:

Step 1: Create the Key Distribution Services Root Key First, you need to create the KDS Root Key, which is required for the gMSA to function. You can do this with the following PowerShell command:

Add-KdsRootKey –EffectiveTime ((get-date).addhours(-10))

Note: The -EffectiveTime parameter is set to 10 hours in the past to ensure immediate effect.

Step 2: Create the gMSA Next, use the New-ADServiceAccount cmdlet to create the gMSA:

New-ADServiceAccount -Name gMSA1 -DNSHostName gmsa1.domain.com -PrincipalsAllowedToRetrieveManagedPassword SRV1$

Replace domain.com with your actual domain name.

Step 3: Install the gMSA on SRV1 Now, you need to install the gMSA on the server SRV1. Run the following command on SRV1:

Install-ADServiceAccount -Identity gMSA1

Step 4: Test the gMSA To ensure that the gMSA is installed correctly and ready for use, perform a test using:

Test-ADServiceAccount -Identity gMSA1

If the test returns True, the gMSA is correctly installed and ready for use on SRV1.

Step 5: Configure the Service to Use the gMSA Finally, configure the service that requires the gMSA to use gMSA1 by setting the service’s logon account to domain\gMSA1$ and leave the password field blank.

This will create and make the gMSA gMSA1 available on SRV1. Ensure that you have the necessary permissions and that SRV1 is properly joined to the domain before proceeding with these steps123.

One possible solution to prevent domain users from saving executable files in a share named \SRVl\Data is to use file screening on the file server. File screening allows you to block certain files from being saved based on their file name extension. Here are the steps to configure file screening:

On the file server, open File Server Resource Manager from the Administrative Tools menu.

In the left pane, expand File Screening Management and click on File Groups.

Right-click on File Groups and select Create File Group.

In the File Group Properties dialog box, enter a name for the file group, such as Executable Files.

In the Files to include box, enter the file name extensions that you want to block, such as .exe, .bat, .cmd, .com, .msi, .scr. You can use wildcards to specify multiple extensions, such as *.exe.

Click OK to create the file group.

In the left pane, click on File Screen Templates.

Right-click on File Screen Templates and select Create File Screen Template.

In the File Screen Template Properties dialog box, enter a name for the template, such as Block Executable Files.

On the Settings tab, select the option Active screening: Do not allow users to save unauthorized files.

On the File Groups tab, check the box next to the file group that you created, such as Executable Files.

On the Notification tab, you can configure how to notify users and administrators when a file screening event occurs, such as sending an email, logging an event, or running a command or script. You can also customize the message that users see when they try to save a blocked file.

Click OK to create the file screen template.

In the left pane, click on File Screens.

Right-click on File Screens and select Create File Screen.

In the Create File Screen dialog box, enter the path of the folder that you want to apply the file screening to, such as \SRVl\Data.

Select the option Derive properties from this file screen template (recommended) and choose the template that you created, such as Block Executable Files.

Click Create to create the file screen.

Now, domain users will not be able to save executable files in the share named \SRVl\Data. They will be able to save other files to the share.

One possible solution to monitor the security configuration of DC1 by using Microsoft Defender for Cloud is to use the Guest Configuration feature. Guest Configuration is a service that audits settings inside Linux and Windows virtual machines (VMs) to assess their compliance with your organization’s security policies. You can use Guest Configuration to monitor the security baseline settings for Windows Server in the Microsoft Defender for Cloud portal by following these steps:

On DC1, open a web browser and go to the folder named \dc1.contoso.com\install. Download the Guest Configuration extension file (GuestConfiguration.msi) and save it to a local folder, such as C:\Temp.

Run the Guest Configuration extension file and follow the installation wizard. You can choose to install the extension for all users or only for the current user. For more information on how to install the Guest Configuration extension, see Install the Guest Configuration extension.

After the installation is complete, sign in to the Microsoft Defender for Cloud portal (2).

In the left pane, select Security Center and then Recommendations.

In the recommendations list, find and select Vulnerabilities in security configuration on your Windows machines should be remediated (powered by Guest Configuration).

In the Remediate Security Configurations page, you can see the compliance status of your Windows VMs, including DC1, based on the Azure Compute Benchmark. The Azure Compute Benchmark is a set of rules that define the desired configuration state of your VMs. You can also see the number of failed, passed, and skipped rules for each VM. For more information on the Azure Compute Benchmark, see Microsoft cloud security benchmark: Azure compute benchmark is now available.

To view the details of the security configuration of DC1, click on the VM name and then select View details. You can see the list of rules that apply to DC1 and their compliance status. You can also see the severity, description, and remediation steps for each rule. For example, you can see if DC1 has the latest security updates installed, if the firewall is enabled, if the password policy is enforced, and so on.

To monitor the security configuration of DC1 over time, you can use the Compliance over time chart, which shows the trend of compliance status for DC1 in the past 30 days. You can also use the Compliance breakdown chart, which shows the distribution of compliance status for DC1 by rule severity.

By using Guest Configuration, you can monitor the security configuration of DC1 by using Microsoft Defender for Cloud and ensure that it meets your organization’s security standards. You can also use Guest Configuration to monitor the security configuration of other Windows and Linux VMs in your Azure environment.

Modify the trust on: DC2

Modify the permissions for the: Computer object of SRV1

In an Active Directory Domain Services (AD DS) environment involving multiple forests and external trusts, managing granular access across domain boundaries is achieved through Selective Authentication. According to official documents for Administering Windows Server Hybrid Core Infrastructure, there are two primary authentication settings for a trust: Domain-wide authentication and Selective authentication.

When you need to restrict users from a trusted forest (contoso.com) so they can only access specific resources in the trusting forest (adatum.com), you must configure the trust to use Selective Authentication. This configuration must be performed in the resource domain (the trusting domain). Based on the provided table, DC2 is the domain controller for adatum.com, which is where the shared resources (SRV1) reside. Therefore, you must modify the trust properties on DC2 to enable Selective Authentication for the incoming trust from contoso.com.

Once Selective Authentication is enabled, Windows does not automatically grant the "Authenticated Users" SID to the user's access token for resources in the local domain. Instead, administrators must explicitly grant the Allowed to Authenticate permission on the specific resource's computer object. In this scenario, since the requirement is to restrict access specifically to resources on SRV1, you must modify the security permissions on the Computer object of SRV1 in Active Directory Users and Computers. By granting the contoso.com users (or a group containing them) this permission, they can successfully authenticate against SRV1 while being blocked from all other servers in the adatum.com forest. This satisfies the requirement to prevent access to any other resources while maintaining the ability of adatum.com users to access contoso.com (as the 2-way trust remains intact).

One possible solution to register SRV1 to sync Azure file shares using the 34646045 Storage Sync Service is to use the Register-AzStorageSyncServer cmdlet from the Az.StorageSync module. This cmdlet establishes a trust relationship between the server and the Storage Sync Service, which is required for creating server endpoints and syncing files. Here are the steps to register SRV1 using the cmdlet:

On SRV1, open PowerShell as an administrator and run the following command to install the Az.StorageSync module if it is not already installed:

Install-Module -Name Az.StorageSync

Run the following command to import the Az.StorageSync module:

Import-Module -Name Az.StorageSync

Run the following command to sign in to your Azure account and select the subscription that contains the 34646045 Storage Sync Service:

Connect-AzAccount

Select-AzSubscription -SubscriptionId

Run the following command to register SRV1 with the 34646045 Storage Sync Service. You need to specify the resource group name and the Storage Sync Service name as parameters:

Register-AzStorageSyncServer -ResourceGroupName -StorageSyncServiceName 34646045

Wait for the registration to complete. You can verify the registration status by checking the Registered servers tab on the Azure portal or by running the following command:

Get-AzStorageSyncServer -ResourceGroupName -StorageSyncServiceName 34646045

Now, SRV1 is registered with the 34646045 Storage Sync Service and ready to sync Azure file shares. You can create server endpoints on SRV1 and cloud endpoints on the Azure file shares to define the sync topology.

To create a container image named app1 for your application using the Dockerfile in the C:\app directory on SRV1, follow these steps:

Step 1: Open PowerShell or Command Prompt First, open PowerShell or Command Prompt on SRV1.

Step 2: Navigate to the Application Directory Change to the directory where your application and Dockerfile are located:

cd C:\app

Step 3: Build the Container Image Use the docker build command to create the container image. The -t flag tags the image with the name app1:

docker build -t app1 .

The period . at the end of the command tells Docker to use the Dockerfile in the current directory.

Step 4: Verify the Image Creation After the build process completes, verify that the image app1 has been created successfully by listing all images:

docker images

You should see app1 in the list of images.

Step 5: Use the Image Now, you can use the image app1 to run containers or push it to a container registry if needed.

By following these steps, you’ll have created a Docker container image named app1 using the Dockerfile located in C:\app on SRV11. Ensure that Docker is installed on SRV1 and that you have the necessary permissions to execute these commands.

To collect the recommended Windows Performance Counters from SRV1 in a Log Analytics workspace, you can follow these steps:

Step 1: Access the Log Analytics Workspace Log in to the Azure portal and navigate to your Log Analytics workspace.

Step 2: Configure Performance Counters In the Log Analytics workspace, select Advanced settings and then choose Data > Windows Performance Counters1. You can add the recommended performance counters by selecting the + button. If you’re using legacy agent management, you can add counters from the Legacy agents management menu2.

Step 3: Add Performance Counters Select the counters you want to collect. You can add common counters quickly by checking the boxes next to them. For specific counters, enter the name of the counter in the format object(instance)\counter. For example, to collect the Processor Time counter for all instances of the Processor object, specify Processor(_Total)\% Processor Time.

Step 4: Set Sample Interval When adding a counter, you can set the sample interval, which is the frequency at which data is collected. The default is 10 seconds, but you can change this to a higher value if needed.

Step 5: Apply Configuration After adding the desired performance counters, select Apply at the top of the screen to save the configuration.

Step 6: Install and Configure the Agent Ensure that the Microsoft Monitoring Agent (MMA) is installed on SRV1. Configure the agent to report to your Log Analytics workspace by specifying the workspace ID and key during setup.

Step 7: Verify Data Collection After the agent is configured, it will start collecting the specified performance counters. You can verify the data collection in the Log Analytics workspace by running queries against the collected data.

Note: The legacy Log Analytics agent will be deprecated by August 2024. Migrate to the Azure Monitor agent before this date to continue ingesting data3.

By following these steps, you should be able to collect the recommended Windows Performance Counters from SRV1 in your Log Analytics workspace. Ensure that you have the necessary permissions and that SRV1 has network connectivity to Azure services.

To configure the domain to support the creation of gMSAs, you need to perform the following steps:

On a domain controller or a computer that has the Remote Server Administration Tools (RSAT) installed, open PowerShell as an administrator and run the following command to install the Active Directory module:

Install-WindowsFeature -Name RSAT-AD-PowerShell

Run the following command to create a Key Distribution Service (KDS) root key, which is required for generating passwords for gMSAs. You only need to do this once per domain:

Add-KdsRootKey -EffectiveImmediately

Wait for at least 10 hours for the KDS root key to replicate to all domain controllers in the domain. Alternatively, you can use the -EffectiveTime parameter to specify a past date and time for the KDS root key, but this is not recommended for security reasons. For more information, see Add-KdsRootKey.

After the KDS root key is replicated, you can create and configure gMSAs using the New-ADServiceAccount and Set-ADServiceAccount cmdlets. For more information, see Create a gMSA and Configure a gMSA.

According to the Administering Windows Server Hybrid Core Infrastructure (AZ-800) exam study materials, Azure DNS Private Resolver allows bidirectional name resolution between on-premises environments and Azure private DNS zones. The Private DNS Resolver consists of inbound endpoints (to resolve queries from on-premises to Azure) and outbound endpoints (to resolve queries from Azure to on-premises DNS servers). For name resolution to work, private DNS zones must be linked to the virtual network associated with the resolver’s hub network.

In this scenario, the planned configuration specifies:

A Private DNS Resolver named Private1 created in the West US region and linked to VNet1.

An inbound endpoint in SubnetB.

The requirement is to identify which private DNS zones will be available for name resolution through this resolver.

From the details given, only Zone1.com and Zone2.com are linked to VNet1, allowing them to participate in name resolution using the resolver. Zone3.com is not linked to VNet1 (either unlinked or linked to another virtual network), and therefore it cannot be resolved through the DNS Resolver in VNet1.

As emphasized in Microsoft’s hybrid infrastructure documentation:

“Private DNS zones must be linked to the same virtual network that contains the Private DNS Resolver or to peered virtual networks for name resolution to succeed.”

Hence, only Zone1.com and Zone2.com are available for name resolution through the Private DNS Resolver.

✅ Correct Answer: C. Zone1.com and Zone2.com only

The AZ-800 materials explain that enabling Microsoft Entra (Azure AD) sign-in to Windows Server running as an Azure VM is done by deploying the Azure AD Login for Windows VM extension. The study guide states that “for Azure VMs, Microsoft Entra sign-in is enabled by installing the AADLoginForWindows extension; once installed, Entra users and groups granted ‘Virtual Machine User/Login’ roles can sign in using Entra credentials.” The required operation is performed from Azure PowerShell with Set-AzVMExtension, providing the publisher Microsoft.Azure.ActiveDirectory, type AADLoginForWindows, and the target VM. Other options are not applicable: Set-AzVM changes VM properties but does not install extensions; New-ADComputer and Add-ADComputerServiceAccount are AD DS cmdlets unrelated to enabling Entra login on an Azure VM. Therefore, to meet the plan “Enable Microsoft Entra users to sign in to Server1,” you must run Set-AzVMExtension to install the AAD Login extension on Server1.

Disk1 (three-way mirror): 2 disks; Disk2 (parity): 1 disk

\In the Administering Windows Server Hybrid Core Infrastructure materials on Storage Spaces resiliency, Microsoft describes how each resiliency type determines simultaneous disk-failure tolerance. The guide explains that mirror spaces keep multiple copies of data: “Two-way mirror writes two copies and can sustain a single disk failure; three-way mirror writes three copies and can sustain the loss of any two disks without data loss.” It also differentiates parity spaces, which stripe data with parity information: “Parity provides capacity efficiency comparable to RAID-5 and tolerates a single disk failure (use dual parity to withstand two failures).”

Applying these to SSPace1:

Disk1 uses a three-way mirror across eight physical disks. By definition, a three-way mirror survives two concurrent disk failures and remains online, satisfying the “always available” requirement.

Disk2 is configured as parity across twelve physical disks. Standard parity (single parity) is equivalent to RAID-5 and survives one disk failure; only dual parity would allow two, but the configuration provided specifies parity (not dual parity).

Therefore, the maximum simultaneous physical disk failures while maintaining availability are 2 for Disk1 and 1 for Disk2.

The exam materials state that Azure Automation runbooks can be authored in PowerShell and Python (along with Graphical and PowerShell Workflow where noted). The module on “Automate management in hybrid environments” specifies: “Runbooks support PowerShell for Windows-based automation and Python for cross-platform scenarios.” It further explains that these languages integrate with Automation Accounts, modules/packages, credentials, and managed identities to run tasks on Azure or hybrid resources through the Hybrid Runbook Worker. Languages such as Java, JavaScript, or Bicep are not runbook languages (Bicep is used for ARM template deployments, not runbook execution). Accordingly, Task1 can be implemented in PowerShell and Python.

To meet the requirement that VM3 be configured for per-folder quotas, the Windows Server file services module directs you to install File Server Resource Manager (FSRM). The course content explains: “FSRM provides quota management, file screening, and storage reporting. Quotas can be applied to volumes and to specific folders, enabling administrators to control the space consumed.” None of the other features listed deliver folder-level quota capability: Enhanced Storage and Windows Standards-Based Storage Management relate to storage management/SMI-S, and iSNS Server concerns iSCSI discovery services. Therefore, the first step is to install FSRM on VM3; after installation, you can create per-folder quota templates and assignments to enforce the desired limits.

The Administering Windows Server Hybrid Core Infrastructure content notes that Microsoft Entra Connect cloud sync uses lightweight agents and supports synchronizing specific OUs from multiple forests into a single tenant. The guide highlights that cloud sync “is designed for multi-forest or cross-organization scenarios and allows scoping to selected OUs and groups,” enabling granular onboarding of just the identities you need. The requirement says “the users in the Marketing OU (in Fabrikam’s forest) must have access to storage1.” Granting access to Azure Files using Entra-based authorization requires that those users exist in the same Entra tenant. Cloud sync enables importing only the Fabrikam Marketing OU into A. Datum’s tenant without establishing full trust for all users. Azure AD Connect in active or staging mode would target the A. Datum forest and isn’t intended for selectively bringing in a separate partner forest OU; AD FS is a federation solution and does not create tenant objects for ACLs on Azure resources like Azure Files. Therefore, implement Microsoft Entra Connect cloud sync and scope it to the Marketing OU to meet the requirement.

Comprehensive and Detailed Explanation with all Administering Windows Server Hybrid Core Infrastructure documents: =

In the Administering Windows Server Hybrid Core Infrastructure study materials, Automanage for Azure VMs is described as a service that “onboards supported Azure virtual machines into a curated set of best-practice services automatically.” The guide notes that Automanage supports Azure IaaS VMs running Windows Server (2012 R2 and later) and common Linux distributions (for example Ubuntu/RHEL), while unsupported operating systems such as Windows client SKUs or older Windows Server releases are excluded. The same content emphasizes that Automanage targets “only supported Azure VMs” and does not extend to machines that don’t meet OS prerequisites.

Given the scenario, Server1 (supported Linux server) and Server2 (supported Windows Server) meet Automanage prerequisites, whereas the remaining Azure VMs are not in the supported matrix (client OS or an older/unsupported server release). Therefore, enabling Automanage on Server1 and Server2 only satisfies the technical requirement to “use Azure Automanage on all supported Azure virtual machines.”

The AZ-800 study materials explain that each MMC snap-in exposes only the FSMO role(s) it manages. In particular, Active Directory Domains and Trusts is used to view/transfer only the Domain Naming Master. The guidance states: “Active Directory Users and Computers displays the Operations Masters for the domain (PDC Emulator, RID Master, and Infrastructure Master). Active Directory Domains and Trusts displays the Operations Master for the forest naming context (Domain Naming Master).” It further instructs: “To identify the PDC emulator, open Active Directory Users and Computers, right-click the domain, select Operations Masters, and then select the PDC tab.” Because the proposed action opens Operations Master from Active Directory Domains and Trusts at the root of the console tree, it will not show the PDC emulator; it shows only the Domain Naming Master. Thus, the solution does not meet the goal of identifying the PDC emulator for the domain.

In the Administering Windows Server Hybrid Core Infrastructure objectives for publishing on-premises apps to cloud identities, Azure AD Application Proxy is the prescribed solution for exposing internal, Kerberos-based web apps to Azure AD users with minimal changes. The guidance explains that Application Proxy is a cloud service in Azure AD which publishes internal HTTP/HTTPS applications and supports Kerberos Constrained Delegation (KCD) so that “users authenticate with Azure AD and the service performs single sign-on to the on-premises app using Kerberos.” To enable it, you turn on the Application Proxy service in the Azure AD tenant and configure the application object for passthrough/Pre-Auth and KCD. The on-premises requirement is to install the Azure AD Application Proxy connector on a domain-joined Windows Server that can reach the internal application; the connector establishes outbound-only connections to the service, avoiding inbound firewall changes and minimizing administrative effort. The materials also contrast this with Web Application Proxy (WAP) for AD FS publishing, which requires additional infrastructure and does not leverage Azure AD cloud pre-authentication. Therefore, to let Azure AD accounts reach an on-premises Kerberos-only app with least effort, configure the Azure AD Application Proxy service (in Azure AD) and deploy the Azure AD Application Proxy connector (on-premises), then enable KCD for the published app.

On VM1: Install and configure Routing and Remote Access

In Azure VNets, layer-3 routing between subnets is provided by the platform, but if you want a VM to act as a router (NVA) and forward traffic between subnets, two things are required: the NIC must be allowed to pass traffic not destined to itself, and the guest OS must be configured to perform IP forwarding/routing. The Administering Windows Server Hybrid Core Infrastructure guidance for “Manage and maintain Windows Server IaaS virtual machines” and “Implement on-premises and hybrid networking” explains that Azure requires IP forwarding to be enabled on the NIC for any VM acting as a router or load balancer so that the fabric will deliver transit packets to the VM instead of dropping them. The Windows Server role that provides routing is Routing and Remote Access (RRAS); enabling the LAN routing feature configures the TCP/IP stack to forward packets between interfaces (including forwarding back out the same interface when used with Azure’s virtual switch). The same material notes that adding extra NICs is not mandatory for simple transit scenarios, and that user-defined routes can be used when you need to steer traffic through the router; however, to enable the VM itself to route, the minimal administrative steps are: turn on IP forwarding for the NIC in Azure and install/configure RRAS in the guest. This combination allows VM1 to route traffic between Subnet1 and Subnet3 with the least effort.

Process isolation: image1 only

Hyper-V isolation: image1, image2, image3, and image4

The Administering Windows Server Hybrid Core Infrastructure materials explain two Windows container isolation modes. For process isolation, the guide states that Windows Server containers share the host’s kernel and therefore require kernel/OS-version compatibility: “Process-isolated Windows containers run directly on the host and use the host’s kernel; the container image must match the host OS version/build.” Because Host1 is Windows Server 2022, only a Windows Server 2022 container image can be run with process isolation. Thus, among the images shown, image1 (Windows Server 2022) is the only one eligible for process isolation; 2019 and 2016 images have kernel mismatches and cannot run in that mode.

The same materials describe Hyper-V isolation as running each container inside a lightweight utility VM: “Hyper-V–isolated containers get their own kernel inside a special VM, removing the kernel version dependency on the host.” This mode “allows running different Windows versions than the host” and, when LCOW/WSL is present, it “enables running Linux containers on Windows” by supplying a Linux kernel within the utility VM. Since Host1 has the Subsystem for Linux installed, Hyper-V isolation can run Windows Server 2022, 2019, 2016 container images and also Linux containers. Therefore, to maximize isolation, you can run image1, image2, image3, and image4 with Hyper-V isolation, while process isolation is limited to image1 only.

The networking section of the AZ-800 material specifies that Switch Embedded Teaming (SET) is the teaming technology for Hyper-V hosts introduced in Windows Server 2016 and enhanced in later versions. The guide highlights that SET “integrates teaming into the Hyper-V virtual switch,” and supports advanced offloads including RDMA, VMMQ/d.VMMQ, SR-IOV, and RSS when the NICs support them. Conversely, the legacy LBFO (Load Balancing/Failover) teaming is described as “not supported with RDMA or VMMQ on Hyper-V hosts” and is deprecated for Hyper-V scenarios. Static or LACP teaming modes refer to LBFO team modes and thus inherit those limitations. Because LAN2 and LAN3 are 25-Gbps adapters that support RDMA and the requirement explicitly calls for NIC learning with Dynamic VMMQ, the prescribed and supported solution is to create a SET team using those two adapters and bind it to the Hyper-V switch. The documentation emphasizes that SET “enables RDMA with SMB Direct and Dynamic VMMQ on teamed NICs,” meeting the performance and capability requirements.

The hybrid connectivity chapter explains Azure Relay (Hybrid Connections/WebSockets) as a service that lets on-premises apps be securely exposed without opening inbound firewall ports. The server initiates an outbound connection to Azure Relay, and Internet clients connect to Azure Relay, which relays traffic over WebSockets to the on-premises listener. The guide emphasizes: “Azure Relay enables exposing services behind firewalls without inbound port openings, supporting WebSockets for bidirectional communication.” Alternatives either require inbound exposure or additional infrastructure: ARR (reverse proxy) and Web Application Proxy run on-premises and would need inbound ports. Azure Application Gateway can proxy HTTP(S) and supports WebSockets pass-through, but to reach an on-prem server you’d typically need VPN/ExpressRoute and corresponding inbound allowances. Since the requirement is to minimize inbound ports on Firewall1 while supporting WebSockets, Azure Relay is the correct solution.
