Hyper-v interview questions and answers
We are elaborate Hyper-v interview questions and answers which is mention below
Ques: -Basic requirement for install cluster
Ans:- DNS: The servers in the cluster must be using Domain Name System (DNS) for name resolution.
Domain role: All servers in the cluster must be in the same Active Directory domain, all clustered servers should have the same domain role.
Domain controllers: We recommend that your clustered servers be member servers. If they are, other servers will be the domain controllers in the domain that contains your failover cluster.
Clients: the clients must be able to connect to the clustered servers
Account for administering the cluster: When you first create a cluster or add servers to it, you must be logged on to the domain with an account that has domain admin rights
Ques:- prerequisites to install hyper v
1-Microsoft recommend minimum of 1.4 GHz 64-bit virtualization enabled processor, we recommend at least 2 GHz processor for Hyper-V Server.
2- Minimum of 512 MB hard disk space to accommodate Hyper-V Server installation,
3- Minimum network adapter.one for management network and one for heart beat
Ques:- How to install hyper v
1-Server Manager, on the Manage menu, click Add Roles and Features.
2-After that click role based. Click Next.
3-After that select a server from the server pool and then click next.
4- After that click hyper v and then click Next.
5- After that select network
6-After that hyper console is open
Ques: What is Hyper-V?
1-Hypervisor technology is service on which multiple virtual machines can run
2-Hyper-V provides the functionality to create a virtualization layer over the physical layer of the host server machine
3-Microsoft’s Hyper-V is a virtualization component that allows for the creation and management of hardware virtualized computing environments through the use of VMs to run multiple operating systems on one physical server.
Ques: Where does Hyper-V place the files and settings for VMs
Ans: Default location of the Vm is C:\Users\Public\Documents\Hyper-V\Virtual Hard Disks.But we can change the location using hyper v setting
Ques:- Type of quorum
Ans: Type of quorum
1-Node majority – Each node in the cluster has a vote
2-Node and disk majority – Each node in the cluster has a vote as does a shared disk
3-Node and file share majority – Each node in the cluster has a vote as does a file share (the file share witness)
4-Disk only – Only a shared disk has a vote
Ques: The key features of Microsoft Hyper-V?
Ans: key features of Microsoft Hyper-V is
1-64-bit supported hypervisor-based virtualization.
2-it is ability to run 32-bit and 64-bit virtual machines.
3-Uniprocessor and multiprocessor virtual machines supported.
4-Virtual machine snapshots, which capture the state, data, and hardware configuration of a running virtual machine. Because snapshots record system states, you can revert the virtual machine to a previous state when is face some problem.
5-Large virtual machine memory support.
6-Virtual local area network (VLAN) support.
Ques: What is csv file in hyper v
1-CSVs allow a cluster of Hyper-V servers to share a set of disks or volumes
2-Any host in the cluster can access any of the shared disks
3-Without CSV, a failover cluster allows a given disk (LUN) to be accessed by only one node at a time
Ques:-What are Hyper-V Integration Components?
1-Integration components install agents into a VM that enable a host to successfully back up a VM, recognize when it has gone down, copy and paste data into and out of a VM
2-synchronize its clock to the host.
3-Hyper-V integration components will be delivered directly to virtual machines using Windows Update
Ques :- What are the prerequisites to install and use Hyper-V?
1-An x64-based processor
2-Hardware-assisted virtualization (Intel VT) or AMD Virtualization (AMD-V)
3-Data Execution Prevention (DEP) must be available
Ques:- What type of disk controller would you In Hyper-V VM
Ans:- There are three type of disk controller in Hyper virtual machine
Ques:-Where can you manage Hyper-V hosts from remotely?
Ans:- We can manage the hyper V using Hyper-V Manager.
Ques:-How do you monitor the performance of your VMs?
Ans:- We can monitor the performance of your VMs with different method
1-Hyper-V Performance Monitor Tool (PowerShell)
Ques:-Types of networks in Hyper-V
Ans:- There are three type of networks in Hyper-V
1-Private Virtual Network:- This type of switch is bound to the physical network cards located in the host.
2-Internal Virtual Network:- This switch is not bound to a physical network card so only allows traffic between VMs and the host
3-External Virtual Network:- This type of switch is only used for virtual machines to communicate with each other
Ques :- What are the system requirements for Hyper-V?
Ans:-Basic Requirement for Hyper v Installation:-
2-Hardware Virtulization supported ((Intel VT) or AMD Virtualization (AMD-V))
3-Minimum of 4 GB memory
Ques:- What is type of files of the vm in hyper v machine
1-.XML files:- These files contain the virtual machine configuration details. There is one of these for each virtual machine and each snapshot of a virtual machine. They are always named with the GUID used to internally identify the virtual machine or snapshot in question.
2-.BIN files:- This file contains the memory of a virtual machine or snapshot that is in a saved state.
3-.VSV files:- This file contains the saved state from the devices associated with the virtual machine.
4-.VHD files:- These are the virtual hard disk files for the virtual machine
5-.AVHD files:-These are the differencing disk files used for virtual machine snapshots
Ques:-What is Virtual Machine Snapshots.
Ans:- 1-A virtual machine snapshot is copied of virtual machine (VM) at a specified time
2-A virtual machine snapshot allows a VM to be restored at state of snapshot creation.
3-Snapshots require adequate storage space. Snapshots are stored as .avhd files in the same location at the virtual hard disk.
Ques:-How do you change that Hyper-V files and setting locations
Ans:– Default location of the Hyper-V files
C:\Users\Public\Documents\Hyper-V\Virtual Hard Disks
Hyper-V Manager, as a property of the server itself. Do this by right-clicking on the server and selecting Hyper-V Settings, then changing both the path for Virtual Hard Disks and the path for Virtual Machines
Ques: -How do you export a Hyper-V VM. tell the method?
1-Gio to the Hyper V manager
2-right click on VM and select export option
3-browse the location where we save the machine
Ques:-What are benefits using CSV?
1-Multiple clustered virtual machines can use the same LUN while still being able to fail over from one node to another node independently
2-Instead, the free space on a Cluster Shared Volume can be used by any VHD file on that LUN.
3-virtual machine can have VHD files accessed by any node in the cluster
4-Hyper-V supports the Live Migration of virtual machines (VMs) using CSV
