Knowing how to plan and implement name resolution for Azure Virtual Desktop is an essential aspect of the AZ-140 Configuring and Operating Microsoft Azure Virtual Desktop certification exam. In this article, we will dive deep into the intricacies of Azure name resolution and step by step guide to plan and implement it for your Azure Virtual Desktop.
Understanding Name Resolution in Azure
Name resolution in Azure refers to the process of converting domain names into IP addresses, thereby directing network traffic appropriately. Azure relies on the same DNS (Domain Name System) that most internet services use to facilitate name resolution.
Azure provides two options for DNS resolution – Azure-provided DNS and Custom DNS.
| Azure-Provided DNS | Custom DNS |
|---|---|
| Out-of-the-box solution from Azure | User-defined solution |
| Automatic resolution of virtual machine (VM) names | Uses As a DNS server configuration |
| Uses an internal IPv4 address | Uses user-provided DNS servers |
Plan for Name Resolution in Azure Virtual Desktop
Planning for name resolution within your Azure Virtual Desktop environment involves a few essential steps:
- Determine a DNS Solution: Choose between Azure’s DNS and a custom DNS solution after considering the specific needs of your organization.
- Establish DNS Zones: Establish and configure DNS zones to manage domain-name-to-IP-address mappings.
- Allocate DNS Servers: Allocate DNS servers to your Azure Virtual Network (VNet) based on your chosen DNS solution.
- VM Name Resolution: If using Azure-Provided DNS, plan for automatic VM name resolution.
Implement Name Resolution for Azure Virtual Desktop
Implementing Azure DNS involves interfacing your DNS solution with Azure Virtual Desktop and the broader Azure platform. Below are the steps;
- Create or Configure your DNS Zone:
- For Azure-provided DNS, Azure will automatically create a DNS zone for every VNet you create. You don’t team any additional setup.
- For a Custom DNS, you’ll need to create a new DNS zone manually via the Azure portal or Azure CLI.
- Assign DNS Servers:
- For Azure-provided DNS, Azure assigns DNS servers automatically.
- For a Custom DNS, you’ll need to configure your DNS servers manually.
- Configure DNS for VMs:
- If you’re using Azure-provided DNS, your VMs will automatically be configured with Azure’s DNS.
- If you’re using a custom DNS solution, you’ll need to configure your VMs to use it.
- Set Up DNS Forwarding: If you’re using a custom DNS solution and want to resolve names in your on-premises network from Azure, you’ll need to set up DNS forwarding.
By understanding and implementing name resolutions, you ensure network communication in your Azue Virtual Desktop is safe and efficient. It is an important concept for the AZ-140 exam and helps in real-world application in configuring and operating Microsoft Azure Virtual Desktop.
Remember, the best solution will depend entirely on the needs of your organization. As such, be sure to fully explore the features and benefits of both Azure-provided and custom DNS solutions to select the best one for your organization. You can then use the steps outlined above to plan and implement your chosen solution.

Answer: A. internal to Microsoft name resolution
Explanation: The Azure Private DNS Zone service is mostly utilized for the administration of internal name resolution within Microsoft networks.
Azure Private DNS Zone service can operate in any region within Azure: True/False?
- True
- False
Answer: False
Explanation: Azure Private DNS Zone service operates within an individual Virtual Network (VNet) within Azure, not across regions within Azure.
Which service is responsible for the automatic registration of Virtual Machine (VM) names in Azure?
- A. Azure Active Directory
- B. Azure Private DNS Zone
- C. Azure Public DNS Zone
- D. Azure Traffic Manager
Answer: B. Azure Private DNS Zone
Explanation: Azure Private DNS Zone is responsible for the automatic registration & deregistration of VM names in the Azure Network.
Azure Public DNS Zone is mostly used for ___________.
- A. Internal name resolution
- B. External name resolution
Answer: B. External name resolution
Explanation: Azure Public DNS Zone often handles external name resolution like making your applications available to the public internet.
To set up name resolution for Azure Virtual Desktop, you can use solely Azure portal: True/False?
- True
- False
Answer: False
Explanation: Besides using Azure portal, you can use Azure PowerShell, Azure CLI, or RESTful API to set up name resolution for Azure Virtual Desktop.
The Azure Private DNS Zone associates a VM’s IP Address and _____.
- A. Name
- B. ID
- C. Location
- D. Storage size
Answer: A. Name
Explanation: The Azure Private DNS Zone automatically registers a VM’s Name & IP Address for easy recognition & communication within the network.
True or False: The Azure Private DNS Zone is cross-platform compatible.
- True
- False
Answer: True
Explanation: The Azure Private DNS Zone is indeed cross-platform compatible and works with various client operating systems.
Name resolution is a primary component for network communication in Azure Virtual Desktop: True/False?
- True
- False
Answer: True
Explanation: Without name resolution, network resources will fail to communicate properly, hence name resolution is essential in Azure Virtual Desktop.
Which of these is NOT a method to automate DNS registration for VMs in Azure?
- A. Azure Private DNS Zone
- B. Azure Active Directory
- C. PowerShell automation scripts
- D. Azure Automation Account
Answer: B. Azure Active Directory
Explanation: Azure Private DNS, PowerShell scripts, and Automation Account are the methods usually used to automate DNS registration for VMs. Azure Active Directory is mainly focused on identity and access management.
Interview Questions
What is Azure Virtual Desktop?
Azure Virtual Desktop is a desktop and app virtualization service that runs on the cloud.
How does name resolution work in Azure?
Name resolution for VMs in Azure is provided through Azure-provided DNS or Custom DNS. The DNS system resolves domain names to IP addresses.
What are the name resolution options available in Azure Virtual Desktop?
Name resolution in Azure Virtual Desktop can be handled by Azure-provided DNS or you can use your own DNS solution.
How does Azure-provided DNS handle name resolution?
Azure-provided DNS is a multisourced, multitenant service which serves Azure-wide queries. It resolves the names of VMs in the same virtual network and cloud services deployed in the same virtual network.
How to configure Azure-provided DNS for Azure Virtual Desktop?
Azure-provided DNS is pre-configured out of the box and it does not require any further configuration.
What are the benefits of custom DNS in Azure Virtual Desktop?
Custom DNS offers more flexibility and control over your DNS settings, allowing for DNS-based features like custom domain names.
How do you configure a custom DNS for Azure Virtual Desktop?
To configure custom DNS, navigate to the settings of your virtual network in the Azure portal and specify your DNS server’s IP address in the DNS servers settings.
What requirements are there for setting up a custom DNS?
The DNS server(s) specified must be reachable from the virtual network where your VMs are deployed.
How does Azure Virtual Desktop handle DNS queries for domain-joined VMs?
For domain-joined VMs, DNS queries are sent to the default DNS server specified in the Azure virtual network, which is the DNS server associated with the domain controller.
If a DNS query fails in Azure Virtual Desktop, how is it handled?
The DNS query will attempt to fall back to the Azure-provided DNS service for name resolution if the primary DNS server configured in the network settings fails to respond.
Can you distinguish different Azure Virtual Desktop instances through DNS?
Yes, each Azure Virtual Desktop instance has its own unique DNS name.
How can you confirm that your DNS setup is working correctly in Azure Virtual Desktop?
You can use the nslookup command-line tool to confirm that your DNS is resolving correctly.
