question
Server virtualization in Windows Server 2012 R2 is based on a module called the _________.
answer
hypervisor Server virtualization in Windows Server 2012 R2 is based on a module called a hypervisor. Sometimes called a virtual machine monitor (VMM), the hypervisor is responsible for abstracting the computer's physical hardware and creating multiple virtualized hardware environments, called virtual machines (VMs)
question
In Windows Server 2012 R2, the hypervisor ________ the host operating system.
answer
loads first, then loads Adding the Hyper-V role actually converts the installed instance of Windows Server 2012 R2 into the parent partition and causes the system to load the hypervisor before the operating system
question
When the Hyper-V role is added to a Windows Server 2012 R2 server, the hypervisor creates the individual environments, each of which has its own operating system installed and accesses the computer's hardware via the hypervisor. What are those individual environments called?
answer
partitions The hypervisor creates individual environments called partitions, each of which has its own operating system installed and accesses the computer's hardware via the hypervisor. Unlike Type II virtualization, no host operating system shares processor time with the hypervisor. Instead, the hypervisor designates the first partition it creates as the parent partition and all subsequent partitions as child partitions.
question
Using the Standard edition of Windows Server 2012 R2, you need to create 5 virtual machines. On how many can you install Windows Server 2012 R2?
answer
2 The licensing restrictions of the Windows Server 2012 R2 Standard and Datacenter editions do not govern how many virtual machines you can create. They govern only what operating system you are permitted to install on the virtual machines. For example, you can use a Standard edition license to create only two virtual instances of Windows Server 2012 R2, but you can also create any number of virtual machines running a free Linux distribution.
question
What is the least expensive way an administrator can experiment with Hyper-V and virtualization?
answer
Download Hyper-V Server for free from the Microsoft website Unlike Windows Server 2012 R2, Hyper-V Server is a free product, available for download from Microsoft's website. However, Hyper-V Server does not include any licenses for virtual instances. You must obtain and license all the operating systems you install on the virtual machines you create.
question
What roles does Microsoft recommend can share the same server as the Hyper-V role?
answer
No other role Microsoft recommends that you do not install other roles with Hyper-V. Any other roles that you need the physical computer to perform are better off implemented within one of the virtual machines you create with Hyper-V.
question
What is the primary graphical tool for creating and managing virtual machines?
answer
Hyper-V Manager The primary graphical tool for creating and managing virtual machines is the Hyper-V Manager console, which you can access from the Tools menu in Server Manager, just as you can any of the other server and Active Directory management tools.
question
Regarding virtual machines, what is Smart Paging used for?
answer
When a VM has to restart and not enough memory is available to allocate its startup RAM value. Windows Server 2012 and Windows Server 2012 R2 improve Dynamic memory by adding the Minimum RAM setting. This enables Hyper-V to reduce the memory used by a virtual machine to a level lower than that needed to start the system, reclaiming that memory for other uses. The problem with having minimum RAM values that are lower than the startup RAM values is that the supply of physical memory can become depleted with too many VMs running simultaneously at their minimum RAM values. To address this possibility, Hyper-V includes a feature called smart paging. If a VM has to restart and not enough memory is available to allocate its startup RAM value, the system uses hard disk space to make up the difference and begins paging memory contents to disk.
question
Assuming your virtual machines has dynamic memory enabled, when does Smart Paging actually trigger?
answer
Smart Paging will only trigger if a VM has shrunken below its Startup RAM toward its Minimum RAM setting. The problem with having minimum RAM values that are lower than the startup RAM values is that the supply of physical memory can become depleted with too many VMs running simultaneously at their minimum RAM values. If this occurs, a VM that has to restart might be unable to do so because not enough free memory is available to increase its memory allocation from its minimum RAM value to its startup RAM value.To address this possibility, Hyper-V includes a feature called smart paging. If a VM has to restart and not enough memory is available to allocate its startup RAM value, the system uses hard disk space to make up the difference and begins paging memory contents to disk.
question
What is Resource Metering?
answer
Resource metering documents virtual machine usage regarding a variety of criteria Resource metering is a PowerShell-based feature in Windows Server 2012 R2 Hyper-V that enables you to document virtual machine usage via a variety of criteria.
question
Using Resource Metering, you are documenting the network traffic and memory usage of all virtual machines on a physical server. What is Resource Metering's statistics associated with?
answer
Statistics are specific to each VM, even if you transfer between host systems Resource metering uses PowerShell cmdlets to track various performance metrics for individual VMs. Resource metering statistics remain consistent, even when you transfer VMs between host systems by using live migration or move virtual hard disk files between VMs.
question
In some cases, certain Hyper-V guest operating system features do not function properly using the OS's own device drivers. What Hyper-V software package can help remedy compatibility issues?
answer
guest integration services In some cases, certain Hyper-V guest operating system features do not function properly using the OS's own device drivers. Hyper-V, therefore, includes a software package called guest integration services, which you can install on your virtual machines for compatibility purposes.
question
Heartbeat, time synchronization, and data exchange between parent and child partitions are all examples of functions provided by ________
answer
guest integration services Examples of where guest integration services can help compatibility issues include operating system shutdown, time synchronization (enables Hyper-V to synchronize the operating system clocks in parent and child partitions), data exchange between operating systems on parent and child partitions, heartbeat (a service in which the parent partition sends regular heartbeat signals to the child partitions, which are expected to respond in kind), and backup, allowing backup of Windows virtual machines using Volume Shadow Copy Services.
question
What types of operating systems are allowable as virtual machine?
answer
Several Microsoft and non-Microsoft OSs such as CentOS 6.0-6.2, Red Hat Enterprise Linux 6.0-6.2, SuSE Linux Enterprise Server 11 SP2 There is an official list of supported guest operating systems available on Microsoft website. Other operating systems might function as well but have not been fully tested.
question
After installing the Hyper-V role, what is the startup procedure for Windows Server 2012 R2?
answer
The newly installed hypervisor starts first, then loads the operating system as the primary or parent partition It might not seem as though the Hyper-V role in Windows Server 2012 R2 provides Type I virtualization, because it requires the Windows Server operating system to be installed and running. However, adding the Hyper-V role actually converts the installed instance of Windows Server 2012 R2 into the parent partition and causes the system to load the hypervisor before the operating system.
question
In Windows Server 2012 R2, which type of VM allows for UEFI boot and SCSI disks to boot the system?
answer

question
Which of the following is the correct scalability limit of Hyper-V in Window Server 2012?
answer
One server can host as many as 1,024 active virtual machines, with each virtual machine up to 64 virtual CPUs and 1 TB of memory A Windows Server 2012 R2 Hyper-V host system can have up to 320 logical processors, supporting up to 2,048 virtual CPUs and up to 4 terabytes (TB) of physical memory. One server can host as many as 1,024 active virtual machines, and each virtual machine can have up to 64 virtual CPUs and up to 1 TB of memory. Hyper-V can also support clusters with up to 64 nodes and 8,000 virtual machines.
question
Windows Server 2012 R2 includes Hyper-V in which edition(s)?
answer
In the Standard and Datacenter editions Windows Server 2012 R2 includes the Hyper-V role only in the Standard and Datacenter editions.
question
Hyper-V in Windows Server 2012 R2 is a Type I virtualization architecture. What is the fundamental difference between Hyper-V and older, Type II virtualization architectures?
answer
Its hypervisor is an abstraction layer and interacts directly with computer hardware, rather than as a host OS application. The virtualization capability built into Windows Server 2012 R2, called Hyper-V, uses a different type of architecture. Hyper-V uses Type I virtualization, in which the hypervisor is an abstraction layer that interacts directly with the computer's physical hardware-that is, without an intervening host operating system.
question
What is the primary purpose of the software package offered by Hyper-V called Guest Integration Services?
answer
Guest Integration Services resolves compatibility issues of certain guest operating systems experiencing non-functioning features. In some cases, certain Hyper-V guest operating system features do not function properly using the OS's own device drivers. Hyper-V, therefore, includes a software package called guest integration services, which you can install on your virtual machines for compatibility purposes.
question
The amount of memory that you want to allocate to the VM when it starts is called ______.
answer
Startup RAM Startup RAM specifies the amount of memory that you want to allocate to the VM when it starts. When you are using Dynamic Memory, this value can be the minimum amount of memory needed to boot the system.
question
In the event physical memory is insufficient to satisfy buffer demands for all VMs, the VM with the higher _____ wins.
answer
Memory weight Memory weight contains a relative value that specifies the priority of this VM, compared to the other VMs on the same computer. When the physical memory in the computer is insufficient to allocate the full buffered amount specified for each VM, the VMs with the highest memory weight settings receive priority.
question
The smallest amount of memory the VM can use at any time is called _______.
answer
Minimum RAM Minimum RAM specifies the smallest amount of memory the VM can use at any time. Operating systems can conceivably require more memory to start up than they do to run, so this value can be smaller than the Startup RAM value.
question
What is the percentage that Hyper-V uses to calculate how much memory to allocate to the VM, compared to its actual utilization, as measured by performance counters?
answer
Memory buffer Memory buffer contains a percentage that Hyper-V uses to calculate how much memory to allocate to the VM, compared to its actual utilization, as measured by performance counters. For example, with the Memory buffer value set to 20%, a VM with applications and operating system that consume 1 GB of memory receives a dynamic allocation of 1.2 GB.
