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

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 ensure that the Azure file share named share1 can sync to on-premises servers is to use Azure File Sync. Azure File Sync allows you to centralize your file shares in Azure Files without giving up the flexibility, performance, and compatibility of an on-premises file server. It does this by transforming your Windows Servers into a quick cache of your Azure file share. You can use any protocol available on Windows Server to access your data locally (including SMB, NFS, and FTPS) and you can have as many caches as you need across the world1.

Here are the steps to configure Azure File Sync for the Azure file share named share1 and the source files located in a folder named \dc1.contoso.com\install:

On the Azure portal, create a Storage Sync Service in the same region as your storage account that contains the Azure file share named share1. For more information on how to create a Storage Sync Service, see How to deploy Azure File Sync.

On the on-premises server that hosts the folder named \dc1.contoso.com\install, install the Azure File Sync agent. For more information on how to install the Azure File Sync agent, see Install the Azure File Sync agent.

On the on-premises server, register the server with the Storage Sync Service that you created in the first step. For more information on how to register a server with a Storage Sync Service, see Register/unregister a server with Storage Sync Service.

On the Azure portal, create a sync group that defines the sync topology for a set of files. In the sync group, select the Azure file share named share1 as the cloud endpoint and the folder named \dc1.contoso.com\install as the server endpoint. For more information on how to create a sync group, see Create a sync group and a cloud endpoint and Create a server endpoint.

Wait for the initial sync to complete. You can monitor the sync progress on the Azure portal or on the on-premises server. For more information on how to monitor sync progress, see [Monitor sync progress].

Once the initial sync is complete, you can add more on-premises servers to the same sync group to sync and cache the content locally. You can also enable cloud tiering to optimize the storage space on the on-premises servers by tiering infrequently accessed or older files to Azure Files.

To create an AD DS site named Site2 that is associated to an IP address range of 192.168.2.0 to 192.168.2.255, you can follow these steps:

On a domain controller or a computer that has the Remote Server Administration Tools (RSAT) installed, open Active Directory Sites and Services from the Administrative Tools menu or by typing dssite.msc in the Run box.

In the left pane, right-click on Sites and select New Site.

In the New Object - Site dialog box, enter Site2 as the Name of the new site. Select a site link to associate the new site with, such as DEFAULTIPSITELINK, and click OK. You can also create a new site link if you want to customize the replication frequency and schedule between the sites. For more information on how to create a site link, see Create a Site Link.

In the left pane, right-click on Subnets and select New Subnet.

In the New Object - Subnet dialog box, enter 192.168.2.0/24 as the Prefix of the subnet. This notation represents the IP address range of 192.168.2.0 to 192.168.2.255 with a subnet mask of 255.255.255.0. Select Site2 as the Site object to associate the subnet with, and click OK.

Wait for the changes to replicate to other domain controllers. You can verify the site and subnet creation by checking the Sites and Subnets containers in Active Directory Sites and Services.

Now, you have created an AD DS site named Site2 that is associated to an IP address range of 192.168.2.0 to 192.168.2.255. You can add domain controllers to the new site and configure the site links and site link bridges to optimize the replication topology.

To manage SRV1 remotely using PowerShell, you’ll need to set up PowerShell Remoting. Here’s a step-by-step guide:

Step 1: Enable PowerShell Remoting on SRV1 On SRV1, run the following command to enable PowerShell Remoting:

Enable-PSRemoting -Force

This command configures the computer to receive PowerShell remote commands that are sent by using the WS-Management technology.

Step 2: Configure the TrustedHosts List (If Needed) If you’re managing SRV1 from a computer that is not part of the same domain, you’ll need to add the managing computer’s name to the TrustedHosts list on SRV1:

Set-Item wsman:\localhost\Client\TrustedHosts -Value "ManagingComputerName" -Concatenate -Force

Replace “ManagingComputerName” with the name of your managing computer.

Step 3: Start a Remote Session From your managing computer, start a remote session with SRV1 using the Enter-PSSession cmdlet:

Enter-PSSession -ComputerName SRV1 -Credential (Get-Credential)

This command prompts you for credentials and then starts a remote session with SRV1.

Step 4: Run Remote Commands Once the remote session is established, you can run any PowerShell command as if you were directly on SRV1. For example:

Get-Service

This command gets the status of services on SRV1.

Step 5: Exit the Remote Session When you’re finished, exit the remote session:

Exit-PSSession

Note: Ensure that both the managing computer and SRV1 are properly configured to communicate over the network, and that any firewalls allow for the necessary ports (default is 5985 for HTTP and 5986 for HTTPS) to be open for WS-Management traffic12.

By following these steps, you should be able to manage SRV1 remotely using PowerShell. Make sure you have the appropriate administrative privileges to perform these actions.

TASK 4

???? Objective:

Enforce a minimum password length of 12 characters for members of the BranchAdmins group only.

Step-by-Step Guide: Fine-Grained Password Policy (FGPP)

Replace "username" with a user from the BranchAdmins group. The output will show the minimum password length (should be 12).

One possible solution to ensure that you can manage DC1 by using Windows Admin Center on SRV1 is to install Windows Admin Center on SRV1 and add DC1 as a managed server. Windows Admin Center is a web-based management tool that allows you to manage servers, clusters, Windows PCs, and Azure virtual machines (VMs) from a single interface. Here are the steps to install Windows Admin Center on SRV1 and add DC1 as a managed server:

On SRV1, open a web browser and go to the folder named \dc1.contoso.com\install. Download the Windows Admin Center installer file (WindowsAdminCenter.msi) and save it to a local folder, such as C:\Temp.

Run the Windows Admin Center installer file and follow the installation wizard. You can choose to install Windows Admin Center as a desktop app or as a service. For more information on how to install Windows Admin Center, see Install Windows Admin Center.

After the installation is complete, launch Windows Admin Center from the Start menu or the desktop shortcut. If you installed Windows Admin Center as a service, you can access it from a web browser by using the URL or :6516, where is the name or IP address of SRV1.

On the Windows Admin Center dashboard, click Add to add a new connection. Select Server as the connection type and enter the name or IP address of DC1 in the Server name field. Optionally, you can specify the display name, description, and tags for the connection. Click Submit to add DC1 as a managed server.

On the Windows Admin Center dashboard, you should see DC1 listed under the Servers section. Click on DC1 to open the server overview page. From here, you can manage various aspects of DC1, such as roles and features, certificates, devices, events, files, firewall, processes, registry, services, and more. For more information on how to use Windows Admin Center to manage servers, see Manage servers with Windows Admin Center.

Now, you can manage DC1 by using Windows Admin Center on SRV1. You can also add more servers or other types of connections to Windows Admin Center and manage them from the same interface

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.

Step-by-Step Guide: Seizing/Transferring the Schema Master Role to DC2

✅ Step 1: Log in to DC2

Use an account that is a member of the Schema Admins, Enterprise Admins, and Domain Admins groups.

✅ Step 2: Register the Schema Snap-in

The Schema snap-in is not loaded by default.

Open Command Prompt as Administrator.

Type the following command to register the schema management DLL:

powershell

Click the Change button to transfer the Schema Master role to DC2.

Click Yes when prompted to confirm the transfer.

✅ Step 6: Verify the Transfer

In the same dialog box, ensure that DC2 is now listed as the Schema Master.

Optionally, run the following command in PowerShell to verify:

netdom query fsmo

The Schema Master should now be DC2.

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.

To ensure that all computers in the domain use DNSSEC to resolve names in the adatum.com zone, you’ll need to configure both the DNS servers and the client computers. Here’s how you can do it:

Step 1: Sign the adatum.com Zone First, you need to sign the adatum.com DNS zone. This can be done using the DNS Manager or PowerShell. Here’s a PowerShell example:

Add-DnsServerSigningKey -ZoneName "adatum.com" -CryptoAlgorithm RsaSha256

Set-DnsServerDnsSecZoneSetting -ZoneName "adatum.com" -DenialOfExistence NSEC3 -NSEC3Parameters 1,0,10,""

This will add a signing key and configure DNSSEC for the zone with NSEC3 parameters.

Step 2: Configure DNS Servers Ensure that your DNS servers are configured to support DNSSEC. This includes setting up trust anchors for the zones that you want to validate and configuring the DNS servers to provide DNSSEC validation for DNS queries.

Step 3: Configure DNS Clients For DNSSEC validation to occur on the client side, the client computers must be configured to trust the DNS server’s validation process. This typically involves configuring the client’s DNS settings to point to a DNS server that supports DNSSEC.

Step 4: Validate Configuration You can validate that DNSSEC is working correctly by using tools like nslookup or dig to query DNS records and check for the presence of DNSSEC signatures in the responses.

Note: The exact steps may vary depending on your environment and the version of Windows Server you are using. Ensure that you have the appropriate administrative rights to make these changes and that you test the configuration in a controlled environment before deploying it domain-wide12.

By following these steps, you should be able to ensure that all computers in your domain use DNSSEC to resolve names in the adatum.com zone.

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.

To map \\dd.contoso.com\instal1 as drive H for all users using Group Policy Preferences and ensure that the new drive mapping takes precedence over any existing mappings, follow these steps:

Step 1: Open Group Policy Management Console Open the Group Policy Management Console (GPMC) on a machine that has administrative privileges over the domain.

Step 2: Create or Edit a GPO Create a new Group Policy Object (GPO) or edit an existing one that applies to the users who need the drive mapping.

Step 3: Navigate to Drive Mappings In the GPO Editor, navigate to:

User Configuration -> Preferences -> Windows Settings -> Drive Maps

Step 4: New Drive Mapping Right-click on Drive Maps and select New -> Mapped Drive.

Step 5: Configure Drive Mapping In the New Drive Properties window, configure the following settings:

Action: Select Replace. This action will overwrite any existing mappings with the same drive letter.

Location: Enter the UNC path \\dd.contoso.com\instal1.

Drive Letter: Choose H: from the drop-down menu.

Reconnect: Check this option if you want the drive mapping to persist across logon sessions.

Label As: Optionally, provide a label for the drive mapping.

Hide/Show this drive: Set according to your preference.

Hide/Show all drives: Set according to your preference.

Step 6: Common Tab Go to the Common tab and configure the following:

Run in logged-on user’s security context (user policy option): Check this option.

Item-level targeting: Click on Targeting and set up any specific criteria if needed.

Step 7: Apply the GPO Click Apply and then OK to save the drive mapping configuration.

Step 8: Link the GPO Link the GPO to an Organizational Unit (OU) or domain that contains the users who should receive the drive mapping.

Step 9: Update Group Policy Instruct users to log off and log back on, or use the gpupdate /force command to refresh Group Policy on their computers.

One possible solution to configure SRV1 as a DNS server that can resolve names from the contoso.com domain by using DC1 and all other names by using the root hint servers is to use conditional forwarding. Conditional forwarding allows a DNS server to forward queries for a specific domain name to another DNS server, while using the normal forwarding or root hint servers for other queries. Here are the steps to configure conditional forwarding on SRV1:

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

In the left pane, right-click on Conditional Forwarders and select New Conditional Forwarder.

In the New Conditional Forwarder dialog box, enter contoso.com as the DNS Domain name.

In the IP addresses of the master servers box, enter the IP address of DC1, which is the DNS server for the contoso.com domain. You can also click on Resolve to verify the name resolution of DC1.

Optionally, you can check the box Store this conditional forwarder in Active Directory, and replicate it as follows if you want to store and replicate the conditional forwarder in AD DS. You can also select the replication scope from the drop-down list.

Click OK to create the conditional forwarder.

Now, SRV1 will forward any queries for the contoso.com domain to DC1, and use the root hint servers for any other queries. You can test the name resolution by using the nslookup command on SRV1 or another computer that uses SRV1 as its DNS server. For example, you can run the following commands:

nslookup

nslookup

The first command should return the IP address of from DC1, and the second command should return the IP address of from a root hint server.

TASK 6

???? Objective:

Enable nested virtualization for a VM (VM1) on SRV1.

Step-by-Step Guide: Enable Nested Virtualization

✅ Step 1: Verify Requirements

Nested virtualization requires:

SRV1 to have a processor that supports Intel VT-x or AMD-V.

Hyper-V role installed on SRV1.

VM1 must be turned off.

✅ Step 2: Open PowerShell on SRV1

Log in to SRV1 with an account that has administrative privileges.

Open PowerShell as Administrator.

✅ Step 3: Enable Nested Virtualization

Run the following command:

Set-VMProcessor -VMName "VM1" -ExposeVirtualizationExtensions $true

✅ Step 4: Verify Nested Virtualization

To confirm the change, run:

Get-VMProcessor -VMName "VM1" | Format-List ExposeVirtualizationExtensions

✅ The output should show:

ExposeVirtualizationExtensions : True

✅ Step 5: Configure Network Adapter (Optional for Nested VMs)

Nested virtualization requires MAC address spoofing for the VM network adapter.

Run:

Set-VMNetworkAdapter -VMName "VM1" -MacAddressSpoofing On

✅ Step 6: Start the VM

Use PowerShell:

Start-VM -Name "VM1"

Or start the VM in Hyper-V Manager.

Additional Notes

Nested virtualization allows you to run Hyper-V within a VM.

Useful for lab/test environments (e.g., running nested Hyper-V hosts in a VM).

Membership in the Enterprise Admins group or the Domain Admins group in the forest root domain is required.

Data disks can be added and detached without requiring downtime. Changing the VM size requires the VM to be restarted.

Create a domain controller named dc3.corp.fabrikam.com in Vnet1.

In a hybrid network, you can configure Azure virtual machines as domain controllers. The domain controllers in Azure communicate with the on-premises domain controllers in the same way that on-premises domain controllers communicate with each other.

Virtual machines in an Azure virtual network receive their DNS configuration from the DNS settings configured on the virtual network. You need to configure the Azure virtual network to use DC3 as the DNS server. Then all virtual machines in the virtual network will use DC3 and their DNS server.
