Microsoft Administering Windows Server Hybrid Core Infrastructure AZ-800 Exam Dumps: Updated Questions & Answers (October 2025)

One possible solution to ensure that all DHCP clients that get an IP address from SRV1 will be configured to use DC1 as a DNS server is to use the DHCP scope options. DHCP scope options are settings that apply to all DHCP clients that obtain an IP address from a specific scope. You can use the DHCP scope options to specify the DNS server IP address, as well as other parameters such as the default gateway, the domain name, and the DNS suffix. Here are the steps to configure the DHCP scope options 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, expand your DHCP server and click on IPv4.

In the right pane, right-click on the scope that you want to configure and select Properties.

In the Scope Properties dialog box, click on the DNS tab.

Check the box Enable DNS dynamic updates according to the settings below. This option allows the DHCP server to register and update the DNS records for the DHCP clients.

Select the option Always dynamically update DNS records. This option ensures that the DHCP server updates both the A and PTR records for the DHCP clients, regardless of whether they request or support dynamic updates.

Check the box Discard A and PTR records when lease is deleted. This option allows the DHCP server to delete the DNS records for the DHCP clients when their leases expire or are released.

Check the box Dynamically update DNS records for DHCP clients that do not request updates. This option allows the DHCP server to update the DNS records for the DHCP clients that do not support dynamic updates, such as legacy or non-Windows clients.

In the DNS servers section, click on the Add button to add a new DNS server IP address.

In the Add Server dialog box, enter the IP address of DC1, which is the DNS server that you want to use for the DHCP clients, and click Add.

Click OK to close the Add Server dialog box and return to the Scope Properties dialog box.

Click OK to apply the changes and close the Scope Properties dialog box.

Now, all DHCP clients that get an IP address from SRV1 will be configured to use DC1 as a DNS server. You can verify the DNS configuration by using the ipconfig /all command on a DHCP client computer and checking the DNS Servers entry. You can also check the DNS records for the DHCP clients by using the DNS Manager console on DC1.

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.

Objective:

Configure the DHCP server SRV1 to lease IP addresses only to computers with MAC addresses starting with AABB in a specific range.

Step-by-Step Guide

✅ Step 1: Open DHCP Management Console

Log in to SRV1 with Domain Admin or DHCP Admin privileges.

Open DHCP Manager:

Press Windows + R, type dhcpmgmt.msc, and press Enter.

✅ Step 2: Create a New DHCP Scope

In the DHCP console, expand SRV1.

Right-click IPv4 and select New Scope.

The New Scope Wizard opens.

✅ Step 3: Configure the Scope

Name:

Enter a name (e.g., MAC-Filtered Scope).

Click Next.

IP Address Range:

Start IP: 192.168.1.190

End IP: 192.168.1.200

Subnet mask: as appropriate (e.g., 255.255.255.0).

Click Next.

Add Exclusions:

None needed unless you want to reserve certain addresses.

Click Next.

Lease Duration:

Set as needed, default is usually fine.

Click Next.

Configure DHCP Options:

You can skip or configure as needed (gateway, DNS, etc.).

Click Next.

Activate Scope:

Click Yes to activate it.

✅ Step 4: Configure MAC Address Filtering (Allow List)

In the DHCP console, expand the scope you created.

Right-click Filters under the scope and choose New Filter.

Enter the MAC address pattern to match devices with MAC addresses starting with AABB:

MAC Address: AABB*

Description: e.g., Allow devices starting with AABB.

Click Add.

✅ Step 5: Enable Allow Filters

Right-click Filters under the scope and select Enable.

Ensure that only devices matching the AABB pattern will receive leases.

✅ Step 6: Test and Verify

Use a test client with a MAC address starting with AABB to ensure it receives an IP address in the 192.168.1.190–192.168.1.200 range.

Use ipconfig /renew on the client, or check the DHCP leases in the Address Leases section.

Objective:

Create a read-only copy of the DNS zone contoso.com on SRV2.

Step-by-Step Guide: Using a Secondary Zone

✅ Step 1: Log in to SRV2

Log in to SRV2 (where you want to host the secondary zone) using an account with local administrative privileges.

✅ Step 2: Open DNS Manager

Press Windows + R, type dnsmgmt.msc, and press Enter.

✅ Step 3: Create a Secondary Zone

In the DNS Manager, expand the server node for SRV2.

Right-click Forward Lookup Zones and select New Zone.

The New Zone Wizard opens.

✅ Step 4: Configure the Secondary Zone

Zone Type:

Select Secondary zone and click Next.

Zone Name:

Type contoso.com and click Next.

✅ Step 5: Allow Zone Transfers on the Primary Server

On SRV1 (or the DNS server hosting the primary zone):

Open DNS Manager.

Right-click the contoso.com zone and select Properties.

Go to the Zone Transfers tab.

Check Allow zone transfers.

Specify SRV2’s IP address (or allow to any server if needed).

✅ Step 6: Verify Zone Replication

On SRV2, refresh the Forward Lookup Zones in DNS Manager.

The contoso.com zone should now appear as a Secondary zone.

Check the Zone Transfer status to ensure it successfully replicated.

One possible solution to configure Hyper-V to ensure that running virtual machines can be moved between SRV1 and SRV2 without downtime is to use Live Migration. Live Migration is a feature of Hyper-V that allows you to move a running virtual machine from one host to another without any noticeable interruption of service. To set up Live Migration between SRV1 and SRV2, you need to perform the following steps:

On both SRV1 and SRV2, open Hyper-V Manager from the Administrative Tools menu or by typing virtmgmt.msc in the Run box.

In the left pane, right-click on the name of the server and select Hyper-V Settings.

In the Hyper-V Settings dialog box, select Live Migrations in the navigation pane.

Check the box Enable incoming and outgoing live migrations.

Under Authentication protocol, select the method that you want to use to authenticate the live migration traffic between the servers. You can choose either Kerberos or CredSSP. Kerberos does not require you to sign in to the source server before starting a live migration, but it requires you to configure constrained delegation on the domain controller. CredSSP does not require you to configure constrained delegation, but it requires you to sign in to the source server through a local console session, a Remote Desktop session, or a remote Windows PowerShell session. For more information on how to configure constrained delegation, see Configure constrained delegation.

Under Performance options, select the option that best suits your network configuration and performance requirements. You can choose either TCP/IP or Compression or SMB. TCP/IP uses a single TCP connection for the live migration traffic. Compression uses multiple TCP connections and compresses the live migration traffic to reduce the migration time and network bandwidth usage. SMB uses the Server Message Block (SMB) 3.0 protocol and can leverage SMB features such as SMB Multichannel and SMB Direct. For more information on how to choose the best performance option, see Choose a live migration performance option.

Under Advanced Features, you can optionally enable the Use any available network for live migration option, which allows Hyper-V to use any available network adapter on the source and destination servers for live migration. If you do not enable this option, you need to specify one or more network adapters to be used for live migration by clicking on the Add button and selecting the network adapter from the list. You can also change the order of preference by using the Move Up and Move Down buttons.

Click OK to apply the settings.

Now, you have configured Hyper-V to enable live migration between SRV1 and SRV2. You can use Hyper-V Manager or Windows PowerShell to initiate a live migration of a running virtual machine from one server to another.

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