Hyper-V Interview Questions and Answers

Here are 20 commonly asked Hyper-V interview questions and answers to prepare you for your interview:

1. Can you explain what Hyper-V is?

Hyper-V is a virtualization platform from Microsoft that allows you to create virtual machines and run them on a physical server. This can be useful for running multiple operating systems on a single server, or for isolating different applications from each other.

2. What are the main components of virtualization with Hyper-V?

The main components of virtualization with Hyper-V are the virtual machine manager, the virtual switch, and the virtual disk. The virtual machine manager is responsible for creating and managing virtual machines. The virtual switch allows virtual machines to communicate with each other and with the outside world. The virtual disk stores the virtual machine’s operating system and data.

3. How do you create a new VM in Hyper-V Manager?

To create a new VM in Hyper-V Manager, open the program and select the “New” option from the top menu. Then, choose “Virtual Machine” from the list of options. This will open the New Virtual Machine Wizard. Follow the prompts to choose a name and location for the VM, specify the amount of memory to allocate, and select the type of networking to use. Finally, choose whether to create a new virtual hard disk or use an existing one.

4. What are some common issues that can occur when creating or managing VMs in Hyper-V?

Some common issues that can occur when creating or managing VMs in Hyper-V include:

– Not enough disk space: When creating a VM, you need to make sure that there is enough disk space on the host machine to accommodate the VM. If there isn’t enough disk space, the VM will not be able to start.

– Incorrect network settings: Another common issue is incorrect network settings. If the network settings are not configured correctly, the VM will not be able to communicate with the outside world.

– Incompatible hardware: Another issue that can occur is incompatible hardware. This can happen if the VM is trying to use hardware that is not supported by Hyper-V.

5. Why is it important to make sure your network adapter type is set correctly?

The network adapter type is important because it tells Hyper-V how to handle traffic for that particular VM. If it is set incorrectly, it can cause problems with networking and communication for the VM.

6. How can you configure Hyper-V networking options?

You can configure Hyper-V networking options by opening the Hyper-V Manager, selecting the host server, and then clicking on the “Virtual Switch Manager” option. From there, you can create virtual switches and configure their settings.

7. Do all Windows OS versions support Hyper-V?

No, only certain versions of Windows support Hyper-V. In order to use Hyper-V, you must have a computer with a 64-bit processor with hardware virtualization support. You also must be running one of the following versions of Windows:
Windows 10
Windows Server 2016
Windows Server 2012 R2
Windows 8.1
Windows Server 2012
Windows 8
Windows Server 2008 R2 SP1

8. What’s the difference between Server Core and Nano Server?

Server Core is a minimal installation of the Windows Server operating system that is designed to be used for specific server roles. Nano Server is a new installation option for Windows Server that is designed to be used for cloud applications and is much smaller and has a reduced attack surface.

9. What is the best way to install Hyper-V on an Azure Virtual Machine?

The best way to install Hyper-V on an Azure Virtual Machine is to use the Azure PowerShell cmdlets. You can use the Install-AzureRmVmRole cmdlet to install the Hyper-V role on an existing Azure VM.

10. What are the advantages of using Hyper-V over other available hypervisors?

Hyper-V has a number of advantages over other available hypervisors. First, it is a native hypervisor, meaning that it does not require an additional software layer to be installed on top of the operating system. This makes it more efficient and easier to manage. Additionally, Hyper-V supports a wider range of guest operating systems than some other hypervisors, making it more versatile. Finally, Hyper-V includes a number of features that make it easier to use and manage, such as live migration and storage replication.

11. What does CPU compatibility mean in context with Hyper-V?

CPU compatibility, in the context of Hyper-V, refers to the ability to use a virtual machine on a host with a different type of CPU. For example, you could use a virtual machine on a host with an Intel CPU, even if the virtual machine was created on a host with an AMD CPU.

12. What is live migration?

Live migration is a feature of Hyper-V that allows you to move a running virtual machine from one host server to another with no downtime. This is possible because the virtual machine’s state is copied over to the new host server while it is still running on the old host server. Once the copy is complete, the virtual machine is then switched over to the new host server and continues to run without any interruption.

13. What are checkpoints used for in relation to Hyper-V?

Checkpoints are used to create a “snapshot” of a virtual machine at a specific point in time. This can be useful if you need to roll back the machine to a previous state, or if you want to save the machine’s state so that you can resume it later.

14. What are the two types of checkpoints supported by Hyper-V? Are there any disadvantages to using them?

There are two types of checkpoints supported by Hyper-V: standard checkpoints and production checkpoints. Standard checkpoints are less resource-intensive and can be used for testing and development purposes. Production checkpoints are more resource-intensive but are designed for use in production environments. There are some disadvantages to using checkpoints, including the potential for data loss if the checkpoint is not properly configured.

15. What is the purpose of Integration Services in Hyper-V?

Integration Services is a set of tools that help to optimize the performance of a virtual machine by providing drivers, services, and utilities that are specifically designed for virtual environments. Integration Services also includes a number of tools for managing and monitoring virtual machines, making it easier to keep track of their performance and ensure that they are running smoothly.

16. What is Dynamic Memory? How does it work?

Dynamic Memory is a feature in Hyper-V that allows a virtual machine to automatically adjust its memory usage based on demand. This means that a VM can start with a small amount of memory and then gradually increase its usage as needed, without the need for manual intervention. This can help to improve overall performance and resource utilization in a virtualized environment.

17. When should you use Generation 1 vs. Generation 2 virtual machines?

Generation 1 virtual machines are best for compatibility with a wide range of operating systems. If you need to run an older operating system or one that is not officially supported by Hyper-V, then you will want to use a Generation 1 VM. Generation 2 virtual machines offer a number of advantages over Generation 1 VMs, including support for UEFI, Secure Boot, and a wider range of devices. If you are running a supported operating system and do not need compatibility with older operating systems, then you should use a Generation 2 VM.

18. What are RemoteFX, Smart Paging, and Enhanced Session Mode?

RemoteFX is a feature in Microsoft’s Hyper-V virtualization platform that allows for the creation of virtual machines with rich 3D graphics capabilities.

Smart Paging is a feature in Hyper-V that allows for the paging of virtual machine memory to disk in order to free up physical memory for other uses.

Enhanced Session Mode is a feature in Hyper-V that allows for the sharing of resources between the host and guest operating systems, including the clipboard, printers, and audio.

19. What is the quick create feature in Hyper-V?

The quick create feature in Hyper-V allows you to quickly create and configure a new virtual machine without having to go through the full setup process. This can be useful if you need to quickly create a new VM for testing or development purposes.

20. Can you give me some examples of how Hyper-V has been used in real world scenarios?

Hyper-V has been used in a number of real world scenarios, including:

– Setting up a virtual test environment to test new software before deploying it to production
– Creating a virtual private cloud (VPC) to host sensitive data
– Building a scalable web platform by hosting multiple virtual machines (VMs) on a single physical server
