1Hyper-V in Windows Server 2012 is a Type I virtulization architecture. What is the fundamental difference between Hyper-V and older, Type II virtualization architectures?
- AHyper-V creates environments called partitions, each with its own operating system installed.
- BIts hypervisor designates the first partition as the parent partition and all subsequent partitions as child partitions.
- CIts hypervisor is an abstraction layer and interacts directly with computer hardware, rather than as a host OS application.
- DComputer subsystems such as Plug and Play and power management are managed by Hyper-V's parent partition.
2Regarding virtual machines, what is Smart Paging used for?
- AWhen a VM has to restart and not enough memory is available to allocate its startup RAM value
- BWhen a VM has to restart and not enough memory is available to allocate its minimum RAM value
- CWhen a VM is overburdened with client traffic and not enough memory is available to allocate its maximum RAM value
- DWhen a VM is overburdened with client traffic and just enough memory is available to allocate is maximum RAM value
3What is the least expensive way an administrator can experiment with Hyper-V and virtualization?
- APurchase the Standard edition of Windows Server 2012, which includes the Hyper-V role.
- BPurchase the Essentials edition of Windows Server 2012, which includes the Hyper-V role.
- CPurchase the Datacenter edition of Windows Server 2012, which includes the Hyper-V role.
- DDownload Hyper-V Server for free from the Microsoft Website
4When the Hyper-V role is added to a Windows Server 2012 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?
- Aservers
- Bpartitions
- Cprocessors
- Dmachines
5Using the Standard edition of Windows Server 2012, I need to create 5 virtual machines. On how many can I install Windows Server 2012?
- A2
- B3
- C4
- D5
6What roles does Microsoft recommend can share the same server as the Hyper-V role?
- AAny other role
- BNo other role
- CFile and print roles
- DWeb server
7In 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?
- Aresource meter
- Bsmart paging
- Cguest integration services
- DHyper-V server
8What is the primary graphical tool for creating and managing virtual machines?
- AServer Manager
- BHyper-V Manager
- CAdd Roles and Features wizard
- DPowerShell
9The amount of memory that you want to allocate the VM when it starts is called __________.
- AStartup RAM
- BMinimum RAM
- CMemory weight
- DMemory buffer
10What is Resource Metering?
- AResource metering documents virtual machine usage regarding a variety of criteria
- BResource metering documents resource usage of host systems that run virtual machines
- CResource metering documents user traffic on virtual machines
- DResource metering enables you to redistribute virtual machine resources
11After installing the Hyper-V role, what is the startup procedure for Windows Server 2012?
- AThe newly installed hypervisor starts first, then loads the operating system as the primary or parent partition
- BThe actual startup procedure is not altered
- CThe newly installed hypervisor starts alongside of the operating system simultaneously
- DThe newly installed hypervisor starts second, after the operating system loads as a partition
12You are using differencing disks for multiple virtual machines (VMs) to preserve the parent image from changes. Now you want to combine the two images together. What PowerShell cmdlet allows you to do this?
- AOptimize-VHD
- BMerge-VHD
- CMount-VHD
- DConvert-VHD
13The smallest amount of memory the VM can use at any time is called _________.
- AStartup RAM
- BMinimum RAM
- CMemory weight
- DMemory buffer
14When creating a snapshot file using Hyper-V Manager, what is the file format and where is it stored?
- AThe file has an AVHD extension, stored in the same folder as the virtual hard disk file.
- BThe file has an AVHDX extension, stored in teh same folder as the virtual hard disk file.
- CThe file has an AVHD or AVHDX extension, stored in teh same folder as the virtual hard disk file.
- DThe file has an AVHD or AVHDX extension, stored at the root of the local drive
15What is the primary purpose of the software package offered by Hyper-V called Guest Integration Services?
- AGuest Integration Services improves communications between the parent partition and child partitions.
- BGuest Integration Services resolves compatibility issues of certain guest operating systems experiencing non-functioning features
- CGuest Integration Services improves data exchange between the parent partition and child partitions.
- DGuest Integration Services improves time synchronization between the parent partition and child partitions.
16Regarding the benefits of a SAN, what happens during serverless backup?
- AThe server schedules the backup, but has no involvement at the beginning, during, or end
- BThe server initiates the backup, but the server is not involved during the backup
- CThe server acts as a slave to the backup device
- DWithout a server, there is no backup
17What does a differencing disk offer administrators?
- AAn opportunity to experiment with no changes committed to the differencing disk
- BA better security for the data on the differencing disk
- CA faster load time than a full VM
- DAn opportunity to experiment with no changes committed to the parent image
18Do VMs ever directly access a physical hard disk?
- ANo, VMs access only virtual hard disks, areas of space on the physical hard disk.
- BYes, VMs access a physical hard disk by way of a "pass-through disk," a special virtual disk that directly accesses the physical disk if it is made exclusively available to the VM
- CNo, VMs access physical hardware only through the hypervisor
- DYes, virtual hard disks associate directly to the physical hard disks.
19Virtual SANs allow you to __________.
- Aeliminate the physical disks
- Bhave virtual hard disks communicate with physical hard disks
- Cmake distant storage accessible to VMs
- Dutilize the Fibre Channel adapters
20Can you modify an existing virtual hard disk (VHD) file
- ANo, once created, a VHD file is fixed
- BYes, but you can modify it only through Windows PowerShell
- CNo, but you change it into a VHDX file
- DYes, you can even modify it without mounting it to a VM
21How do you give a VM exclusive access to a physical hard disk?
- ABy creating a pass-through disk for the VM
- BTaking the disk offline in the parent OS, and then selecting the physical disk in the VM
- CBy granting the physical disk to the VM through the parent OS
- DA VM cannot have exclusive access to physical disks, only virtual disks
