41. You are considering implementing NIC Teaming in a virtual machine running in Hyper-V. The virtual machine is configured with 8 GB of system RAM, a 1 TB virtual hard disk file, and four virtual network adapters. You want to use all of the network adapters in the team to provide load balancing and failover. What should you do? Increase the number of virtual NICs in the team to five. Reconfigure the virtual machine with 16 GB (or more) of system RAM. Increase the size of the virtual disk file to 2 TB (or more). Reduce the number of virtual NICs in the team to two.

Reduce the number of virtual NICs in the team to two. Explanation Hyper-V supports only two adapters in a NIC team. In this scenario, two of the four virtual adapters can be included in the team. The RAM and hard disk file sizes specified in this scenario are adequate for NIC Teaming.

43. *Jumbled* You are configuring a NIC team that is being used for failover only and not bandwidth aggregation. Which NIC teaming configuration must you use? 0 Switch-dependent teaming ..0Switch-independent teaming 0 Link aggregation control protocol teaming 0 Static teaming

..0Switch-independent teaming Explanation Switch-independent teaming allows adapters in a team to be connected to different switches. If the NIC team is being used for failover only and not bandwidth aggregation, the NIC team must be configured as switch-independent. Switch-dependent teaming requires adapters to be connected to the same switch. You can implement switch-dependent teaming in one of two ways: • Generic or static teaming requires that the switch and the host identify the links in the team. • Link Aggregation Control Protocol (LACP) teaming uses LACP to dynamically set the links between the host and the switch.

Virtual Hard Disk (VHD)

A file that resides within the host operating system and serves a storage device for the virtual machine.

Hypervisor

A thin layer of software that resides between the guest operating system and the hardware.

27. You are the network administrator for westsim.com. The network consists of a single Active Directory domain. You are responsible for a server named HV1 that has the Hyper-V role installed. HV1 hosts a virtual machine that runs a custom web application that is in use 24 hours per day. The virtual machine has one hard drive that is hosted on a 127 GB expanding virtual hard drive (.vhdx). The server is running out of room. Management would like to upload 100 GB of new media files for use in the web application. You need to provide more storage space inside the virtual machine while minimizing downtime for the custom web application. What should you do? Add a new virtual hard drive (.vhdx) to the existing IDE controller. Add a new virtual hard drive (.vhdx) to a new IDE controller. Add a new virtual hard drive (.vhdx) to a SCSI controller. Edit the existing virtual hard drive (.vhdx) file.

Add a new virtual hard drive (.vhdx) to a SCSI controller. Explanation Add a new virtual hard drive (.vhdx) to a SCSI controller. Dynamic Virtual Machine Storage allows hot plug-in and hot removal of the storage on a SCSI controller of the virtual machine. Physical machines that support hot swapping of drives only do so on SCSI controllers, and the same is true of virtual machines. Therefore, you must add the new virtual hard drive (.vhdx) to a SCSI controller, which will allow you to add the new .vhdx without having to shut down the virtual machine, eliminating any downtime for the custom web app. Adding a new virtual hard drive (.vhd) to an IDE controller, whether the existing controller or a new one, would require a reboot of the virtual machine. Editing the existing file would allow you to convert the expanding virtual hard drive (.vhd) to a fixed size virtual hard drive, but would not increase the available space. Generally, conversion from a dynamically expanding .vhd to a fixed size .vhd is done for performance issues, since a fixed size .vhd does not require the processor to expand the .vhd as storage requirements increase.

Virtual Machine Queue (VMQ)

Allows network traffic to be distributed across multiple CPU cores

Hypervisor

Allows virtual machines to interact with the hardware without going through the host operating system.

Virtual Machine

Appears to be a self-contained and autonomous system.

16. You need to create a snapshot of a virtual machine currently running on a Windows Server Hyper-V host. The server was installed using a Server Core installation, so you must do this from the command line within a PowerShell window. Which cmdlet should you use to do this? Dismount-VHD Export-VM Checkpoint-VM Export-VMSnapshot

Checkpoint-VM Explanation The Checkpoint-VM cmdlet can be used within a PowerShell window to create a snapshot, or checkpoint, of a virtual machine on a Windows Server Hyper-V host. The Dismount-VHD cmdlet is used to dismount a virtual disk. The Export-VM cmdlet is used to export a virtual machine to a different storage device, such as a removable hard disk. The Export-VMSnapshot cmdlet is used to export a snapshot of a virtual machine to a different storage device, such as a removable hard disk.

24. You currently manage a virtual machine named VM18 that has been installed on the Srv5 physical server. The virtual machine uses a single dynamic disk of 100 GB. You notice that the physical size of the virtual hard disk is 40 GB, but that the virtual machine reports only a total of 20 GB of files. You want to reduce the physical space used by the virtual hard disk. What should you do? In the virtual machine, defragment the hard disk. Create a differencing disk using the virtual machine's disk as the parent disk. Convert the disk to a fixed disk with a smaller size. Compact the disk.

Compact the disk. Explanation With a dynamically expanding disk, additional space is added to the .vhd file as necessary. However, when files are deleted from the virtual hard disk, the .vhd file does not shrink. Compacting the virtual disk removes any blank space from the virtual hard disk file. You can only compact a dynamically expanding disk. By design, fixed disks are always the size of the virtual hard disk capacity. Converting a dynamically expanding disk to a fixed disk makes it bigger; the resulting file consumes as much disk space as is allocated to the virtual hard disk. Microsoft does not provide any tools for shrinking a virtual disk (reducing the maximum size of a virtual disk). Compacting a dynamically expanding disk or converting a fixed disk to dynamically expanding will reduce the disk space used by the virtual disk, but does not reduce the maximum size of the virtual disk.

Storage Quality of Service (QoS)

Controls the throughput of data to virtual disks

23. You currently manage a virtual machine named VM12 that has been installed on the Srv5 physical server. The virtual machine uses a single fixed disk of 100 GB saved in the vdisk1.vhd file. Physical disk space on the server is getting low. When you run Disk Management within the virtual machine, you notice that only 30 GB of space is being used, but the vdisk1.vhd file occupies 100 GB. You want to reduce the physical size of the virtual hard disk. What should you do? Compact the disk. Create a differencing disk named vdisk2.vhd using vdisk1.vhd as the parent disk. Reconfigure the virtual server to use vdisk2.vhd instead of vdisk1.vhd. Convert the disk to a dynamically expanding disk named vdisk2.vhd. Compact the disk. Convert the disk to a fixed disk named vdisk3.vhd. Delete vdisk1.vhd and change vdisk3.vhd's name to vdisk1.vhd. Convert the disk to a dynamically expanding disk named vdisk2.vhd. Delete vdisk1.vhd, and change vdisk2.vhd's name to vdisk1.vhd.

Convert the disk to a dynamically expanding disk named vdisk2.vhd. Delete vdisk1.vhd, and change vdisk2.vhd's name to vdisk1.vhd. Explanation Convert the disk to a dynamically expanding disk. A fixed disk reserves the entire amount of disk space on the physical disk. In this scenario, the disk uses 100 GB of physical disk space, even though the virtual machine only uses 30 GB. Converting the disk to a dynamically expanding disk reduces the size of the disk to use only the amount of used space. Compacting a disk removes extra space from a dynamically expanding disk—you cannot compact a fixed disk. When you convert a dynamically expanding disk to a fixed disk, the fixed disk takes up the entire disk space specified by the maximum disk size; compacting the dynamically expanding disk and then converting it to a fixed disk does not result in a smaller disk. Use a differencing disk to create a child installation from a parent installation. Take a snapshot to save the current state of a virtual machines. Using a differencing disk actually increases the amount of disk space used because the original fixed disk remains while changes are saved to the differencing disk and not the fixed disk (even though the fixed disk might have free space available).

Port Mirroring

Copies traffic from one switch port to another

Testing Functions

Create a lab environment that mirrors your production network to see how an application runs before putting it into production.

Server Consolidation

Migrate an older operating system off of aging hardware and into a virtual machine.

32. You are planning a server virtualization implementation using Hyper-V. Your virtualization solution must meet the following requirements: • Both 32-bit and 64-bit operating systems will be installed as virtual machines. *PLEASE EDIT (JUMBLED ON FORM)* • YAolluvinrteueadl mtoaicnhsitnaellssmixuvsitrtbuealamblaechtoinceosm. municate with each other. • Virtual machines should not be able to communicate with any other network devices. Virtual machines should not be able to communicate with the management operating system. What should you do? Create an external network Create a private network Create an internal network Create a wireless network

Create a private network Explanation Use a private network to allow the virtual machines to communicate with each other and no other devices, including the management operating system. Use an internal network if the private network must include the management operating system. Use an external network if the virtual machines must communicate with other network devices. A wireless network is not a virtual machine network type.

Isolation

Create a sandboxed environment where malware can be executed with minimal risk to equipment and software.

33. You are planning a server virtualization implementation using Hyper-V. Your virtualization solution must meet the following requirements: • Both 32-bit and 64-bit operating systems will be installed as virtual machines. • You need to install six virtual machines. • You will manage the services running on the virtual machines from a Windows computer. What should you do? Create an internal network Create a physical network Create a private network Create an external network

Create an external network Explanation To allow the Windows computer to communicate with the virtual machines, you must configure an external network. Use a private network to allow the virtual machines to communicate with each other and no other devices, including the management operating system. Use an internal network if the private network must include the management operating system. A physical network is not a virtual machine network type.

34. You are planning a server virtualization implementation using Hyper-V. Your virtualization solution must meet the following requirements: • Both 32-bit and 64-bit operating systems will be installed as virtual machines. • You need to install two virtual machines. • Virtual machines must be able to communicate with each other and with the host operatingb system. What should you do? Create an internal network Create a private network Create an external network Create a host network

Create an internal network Explanation Use an internal network if the private network must include the management operating system. Use an external network if the virtual machines must communicate with other network devices. Use a private network to allow the virtual machines to communicate with each other and no other devices, including the management operating system.

22. You have decided to install multiple virtual servers. You install Hyper-V on a server that is running Windows Server 2016 Datacenter edition. You need to install the following virtual machines: • Four servers running the Windows Server 2008 R2 Standard edition (64-bit) • Three servers running the Windows Server 2012 R2 Datacenter edition (64-bit) • Three servers running the Windows Server 2016 Standard edition (64-bit) To conserve disk space, you decide to use parent and differencing disks. You need to create the virtual hard disks used by the virtual machines. What should you do? Create two fixed disks and eight differencing disks. Create one fixed disk and nine differencing disks. Create two fixed disks and ten differencing disks. Create three fixed disks and ten differencing disks. Create three fixed disks and seven differencing disks. Create one fixed disk and ten differencing disks.

Create three fixed disks and ten differencing disks. Explanation When using parent and differencing disks, you create a parent installation for each operating system version or each computer with a similar configuration. In this scenario, you will need three parent installations. Each installation uses a fixed virtual hard disk. After you have created the parent installations, delete the virtual servers, but keep the virtual hard disks. Then create a virtual hard disk for each virtual server that is active. In this scenario, you will need a total of 10 installations, each using a differencing virtual hard disk.

30. Which Hyper-V feature allows you to create read-only parent virtual hard disk files that are linked to child virtual hard disk files that contain only changes made to the parent disk? Snapshots Pass-through disks Dynamically expanding VHD files Differencing disks

Differencing disks Explanation A differencing disk is a virtual hard disk file that is associated with another disk and contains only changes that have been made to the associated disk. The differencing disk is referred to as the child disk; the disk it is associated with is the parent disk. The parent disk remains unchanged. The child disk contains any changes to the parent disk. When you connect a physical hard disk to a virtual machine instead of a virtual hard disk file, the hard disk is referred to as a pass-through disk. A snapshot can be used to restore a virtual machine to a previous state. Dynamically expanding VHD files automatically increase in size as more storage space is consumed by the virtual machine.

Port ACLs

Establishes rules that are applied to virtual switch ports

26. You currently manage a virtual machine named VM12 that has been installed on the Srv5 physical server. The virtual machine uses a single fixed disk of 40 GB saved in the vdisk1.vhd file. The virtual machine is running out of free disk space. The virtual machine currently uses about 39.5 GB of the available disk space. You need to add more disk space to the virtual machine. What should you do? Create a new virtual disk and copy the contents from vdisk1.vhd to it. Configure VM12 to use the new virtual disk instead of vdisk1.vhd. Create a differencing disk using vdisk1.vhd as the parent. Configure VM12 to use the differencing disk instead of vdisk1.vhd. Create a new virtual disk. Merge the new disk with vdisk1.vhd. Convert the disk to a dynamically expanding disk. Expand the vdisk1.vhd disk.

Expand the vdisk1.vhd disk. Explanation Expand a virtual disk to add more space to the disk. You can expand a fixed or a dynamically expanding disk. Both fixed and dynamically expanding disks have a limit on the amount of disk space that the disk uses. A dynamically expanding disk starts out small and expands up to the predefined limit. To allow the disk to go beyond the limit, expand the disk. You could also add space to a disk by adding a second virtual hard disk and then use Disk Management in the virtual machine to span the first volume onto the new virtual disk. Use a differencing disk to create child disks from a parent disk. The total disk space used by a differencing disk is equal to the maximum size of the parent disk—you cannot use a differencing disk to add space to a disk. When creating a new virtual disk, you can copy the contents from an existing physical disk. You cannot copy the contents of a virtual disk when creating a new virtual disk.

28. When you originally deployed the AccServer virtual machine on your Windows Server 2012 R2hypervisor, it stored accounting data from all departments in your organization. Therefore, it required a very large virtual disk. However, as your organization has grown, additional department-specific accounting servers have been deployed and much of the data that used to be stored on AccServer has migrated to them. Because the virtual hard disk file for the AccServer virtual machine is set to grow dynamically, the unused space in the file can be reclaimed on the physical hard drive in the Windows server. Click the option you would use in the Edit Virtual Hard Disk wizard to accomplish this without reducing the overall storage capacity of the virtual hard disk. *INSERT PICTURE*

Explanation A virtual hard disk file that is configured to grow dynamically will increase in size as more space is required by the virtual machine. However, once physical disk blocks are allocated, a disk file does not reduce in size when data is deleted from it. To reduce the size of the disk file, you can use the Compact option in the Edit Virtual Hard Disk wizard. This reduces the size of the disk file without reducing the capacity of the virtual hard disk. The Convert option is used to convert an existing virtual hard disk to a new virtual hard disk using a different type and format. The Expand option expands the capacity of the virtual hard disk. The Shrink option reduces the overall storage capacity of the virtual hard disk itself.

35. Software developers in your organization want to use Hyper-V to create virtual machines to test their new code. You need to add a virtual switch to the system. The virtual switch must allow communication between virtual machines running on the hypervisor, as well as with the hypervisor host itself. However, to contain the effects of bugs that may arise with the code being tested, you want to isolate the virtual machines from other hosts on the physical network. Click on the type of virtual switch you should create. *INSERT PICTURE*

Explanation An internal virtual switch allows virtual machines on the hypervisor host to communicate with each other, as well as with the physical computer itself. However, they are isolated from the physical network that the hypervisor host is connected to. An external virtual switch allows virtual machines to access the physical network. A private virtual switch doesn't allow communications with the hypervisor host.

13. You need to be able to access a partner organization's network using a VPN connection from within a Windows virtual machine running on a Windows server. However, the VPN connection requires a smart card for authentication. In order to connect, you need to redirect the smart card from the local physical hardware to the virtual machine. Click the option in the Hyper-V settings on the server you can use to enable this. *INSERT IMAGE*

Explanation Enhanced Session mode allows you to redirect local resources to a virtual machine session. In Enhanced Session mode, you can redirect resources using a Remote Desktop Connection session using the virtual machine bus, eliminating the need for a network connection. Resources you can redirect to the virtual machine include: • Smart cards • Clipboard • USB devices • Audio • Printers To enable Enhanced Session mode, right-click the server in Hyper-V Manager, click Hyper-V Settings, and then select Allow enhanced session mode under Enhanced Session Mode Policy.

44. Click on the menu option that allows you to enable bandwidth management. *INSERT IMAGE*

Explanation If you want to enable bandwidth management on a virtual machine, open the Settings page for the virtual machine. From the virtual machine's Settings page, select the network adapter for which you want to enable bandwidth management.

45. Click on the menu option that allows you to verify that the virtual machine queue feature is enabled for a virtual machine. *INSERT IMAGE*

Explanation If you want to verify that virtual machine queue is enabled, open the Settings page for the virtual machine and expand the Network Adapter menu option. Select Hardware Acceleration to view the following features: • Virtual machine queue • IPsec task offloading • Single-root I/O virtualization

37. You are configuring a new external virtual switch in your Hyper-V host. You want the virtual machines running on the host to be able to use the physical network adapter installed in the system instead of virtual network interfaces. Click the option you would use to configure the virtual switch in this manner. *INSERT PICTURE*

Explanation *UNSCRAMBLE* TheEnablesingle-root I/O virtualization (SR-IOV) option allows virtual machines to directly use the network adapter specified. In this example, virtual machines would load drivers for and use the Broadcom NetXtreme 57xx Gigabit Controller installed in the hypervisor host instead of a virtual network adapter. The External network drop-down list is used to select a physical network adapter to be used by the virtual switch. The Allow host OS to share the network adapter prevents the physical host from using the adapter used by the virtual switch. Selecting Private network isolates the virtual switch from the physical network.

4. You are managing a Windows Server 2012 virtual machine on a Hyper-V hypervisor host. Dynamic Memory is enabled in the virtual machine's configuration. The virtual machine will run several Web applications that are known to create system memory utilization spikes during heavy use. Because Dynamic Memory is enabled, you are concerned that memory could be unallocated from this virtual machine and reallocated to another, resulting in insufficient memory. You need to ensure that some physical RAM is held in reserve to prevent this from happening. Click the option you would use in the virtual machine's memory configuration to do this. *INSERT IMAGE*

Explanation The Memory Buffer setting under Dynamic Memory manages the memory assigned to the virtual machine compared to the amount of memory needed by the applications and services running on the virtual machine. Hyper-V uses the percentage specified along with the current demand for memory to reserve physical RAM in the system as a buffer. When a memory utilization spike occurs, the buffer will be dynamically added to the virtual machine as needed. The Startup RAM parameter specifies the memory required to start the virtual machine. The Minimum RAM parameter specifies the minimum amount of memory to be assigned to the virtual machine. The Maximum RAM parameter specifies the maximum amount of memory available to the virtual machine. The Memory weight slider determines how to distribute memory amount virtual machines.

38. For security testing purposes, you need to change the source MAC address in outgoing packets originating from a Hyper-V virtual machine. Click the option you would use in the virtual machine's settings to do this. *INSERT IMAGE*

Explanation To change the source MAC address in outgoing packets originating from a Hyper-V virtual machine, click Advanced Features under the network adapter in the virtual machine's settings and then mark Enable MAC address spoofing. Clicking Network Adapter virtual_switch_name in the virtual machine's Settings window allows you to enable bandwidth management. It's not necessary to add new hardware to the virtual machine to enable bandwidth management. Clicking Hardware Acceleration allows you to specify tasks that can be offloaded to the physical network adapter in the system.

42. *JUMBLED* For most of the year, the AccSV virtual machine is only lightly utiliza::l.However,at quarter-end and at year-end, is heavily utilized as accountants h your organization prepare reports and reconcile accounts. You need to ensure the virtual network adapter in this virtual machine has sufficient bandwidth available for these peak periods,so you decide to enable bandwidth management on the adapter.

Explanation To enable bandwidth management on the virtual machine's network interface,click Network Adapter flirWII_SMifdl_tlllfle in the virtual machine's settings window. In this example, the name of the external virtual switch is External. Then, in the Network Adapter screen,click Enable bandwidth management. It's not necessary to add new hardware to the virtuat;tual machine to enable bandwidth management. Clicking Hardware Acceleration allows you to specify tasks that can be official to the physical network adapter in the system. Clicking Advanced Features allows you to configure advanced features,such as NIC Teaming.

39. *JUMBLED* When you initially created your external virtual switch in Hyper-V Manager, you configured the virtual machines connected to directly use the Broadcom NetXtreme 57xx Gigabit Controller installed on the host instead of a virtual network adapter. You ra:entty created a new Whdows 93rver virtual ma:hhe on this host named DevSv and connected s network adapter to the external v rtual switch. You now want to enable the virtual machine to use the physical adapter on the host. Click the option you would use in the virtual ma:hine's setthgs to do this.

Explanation To enable the virtual machine to dira:tly use the physicalnetwork interface associated with an external vrtual switch,click Handware Acceleration under the network adapter in the virtual machine's configuration and then mark Single-root 1/0 virtualization. Ma-king Enable vrtual machine queue creates a dedtated queue on a host's physical network adapter for each virtual network adapter that has requested a queue. Marking Enable IPsec task offload reduces some of the processor performance load associated with IPsec encryption algorithms.

29. You need to add additional disk space to the AccServ virtual machine running on a Windows server. To accomplish this, you decide to create a pass-through disk. Click the option you would use in the virtual machine's settings screen to do this. *INSERT PICTURE*

Explanation When you connect a physical hard disk to a VM, the hard disk is referred to as a pass-through disk. To accomplish this, select Physical hard disk in the virtual machine's settings and then select the disk you want to use from the drop-down list. Note that hard disk must be in an offline state before it can be used as a pass-through disk. Clicking New allows you to create a new virtual hard disk file. Selecting Edit allows you to compact, convert, expand, or shrink an existing virtual hard disk. Clicking Inspect allows you to view the properties of the current virtual hard disk. Clicking Browse allows you to select a different virtual hard disk file.

36. You are configuring a new external virtual switch in your Hyper-V host. The host has two physical network interfaces installed. You want the physical host to exclusively use one network interface and virtual machines running on the host to exclusively use the other. Click the option you would use to configure the virtual switch in this manner. *INSERT PICTURE*

Explanation With two network adapters installed, one can be used by the physical host while the other is used only by virtual machines running on the host. To do this, under External network, select the adapter you wish to use for the virtual switch and then deselect Allow host OS to share the network adapter. This prevents the physical host from using the adapter. The External network drop-down list is used to select a physical network adapter to be used by the virtual switch. The Enable single-root I/O virtualization (SR-IOV) option allows virtual machines to directly use the network adapter specified. The Enable virtual LAN identification for management operation system option allows you to configure the virtual switch to function on a specific VLAN.

31. You are working in Hyper-V Manager on a system that hosts several Windows Server 2008 R2 virtual machines. You create snapshots of these virtual machines nightly as part of your disaster recovery plan. Users are complaining that they can no longer access the virtual servers. In Hyper-V Manager, they are identified as being in a Paused-Critical state. What should you do? (Select two. Each answer is a part of the overall solution.) Upgrade the virtual machines to Windows Server 2012 R2. Install a new physical hard disk in the hypervisor host. Move the snapshot files to the new hard disk. Reboot the hypervisor system. Revert the virtual machines to the most recent snapshot. Reconfigure the virtual machines to use the new drive as a pass-through disk.

Install a new physical hard disk in the hypervisor host. Move the snapshot files to the new hard disk. Explanation After a virtual machine snapshot has been taken, the base virtual hard disk stops expanding and the snapshot file stores all new data that is written to the disk. Therefore, it is critical that there is adequate physical disk space available in the snapshot storage location. If the available hard disk space falls under 200 MB, all running virtual machines will be paused and marked Paused-Critical. An easy way to fix the issue in this scenario is to install an additional physical hard disk in the hypervisor host and then move the snapshots to the new disk. Upgrading the virtual machines to Windows Server 2012 R2 will not resolve the Paused-Critical state, nor will reverting them to a prior snapshot or rebooting the hypervisor host. When you connect a physical hard disk to a VM, the hard disk is referred to as a pass-through disk. This feature will not resolve the issue in this scenario.

Server Consolidation

Move many physical servers onto a few host servers with many virtual machines.

Flexibility

Move virtual machines between hypervisor hosts as needed.

Testing Functions

Verify updates and patches before rolling them out into the production environment.

20. You want to implement Hyper-V so you can create a lab environment that mirrors your production network for testing applications before deploying them into your production environment. You're planning on having four virtual Windows Servers in this lab environment. You plan to use a file server already in production to create your first Hyper-V host system. You have a system with the following specifications and OS installed: • A 64-bit processor with second-level address translation (SLAT). • VM monitor mode extensions. • UEFI that supports virtualization with the following features: • Hardware-assisted virtualization with Intel VT. • Data Execution Prevention (DEP) enabled with Intel Execute Disable Bit (XD). • 64 GB RAM. • Windows Server 2016 Standard edition with the Server Core deployment. Is this system a good choice for hosting your lab environment? Yes, this system meets the best practice suggestions for a dedicated hypervisor host. No, best practice suggests that the system should be a dedicated hypervisor host with only the Hyper-V role installed. No, best practice suggests that the system should be a dedicated hypervisor host using the Windows Server 2016 Datacenter edition with the Desktop Experience deployment. No, best practice suggests that the system should be a dedicated hypervisor host using the Windows Server 2016 Datacenter edition.

No, best practice suggests that the system should be a dedicated hypervisor host with only the Hyper-V role installed. Explanation This system is not a good choice for hosting your lab environment. Best practice suggests that the system should be a dedicated hypervisor host with only the Hyper-V role installed; this system is currently running the file server role. Hyper-V is supported by both the Windows Server 2016 Datacenter and Standard editions. Running virtual machines (VMs) significantly increases hardware resource utilization on the server. Accordingly, consider implementing the following best practices to maximize the system resources available for virtualization: • Consider implementing a dedicated hypervisor host by installing only the Hyper-V role on the server. No other roles should be installed. • Consider implementing Hyper-V on a Server Core installation.

21. You want to implement Hyper-V so you can create a lab environment that mirrors your production network for testing applications before deploying them into your production environment. You're planning on having four virtual Windows servers in this lab environment. Your lab environment will need access to the physical network and the Internet. You plan to use hardware that you already have on hand to create your first Hyper-V host system. You have an unused system with the following specifications and OS installed: • A 64-bit processor with second-level address translation (SLAT) • VM monitor mode extensions • UEFI that supports virtualization with the following features: • Hardware-assisted virtualization with Intel VT • Data Execution Prevention (DEP) enabled with Intel Execute Disable Bit (XD) • 64 GB RAM • Windows Server 2016 Standard edition with the Server Core deployment • A single 1 Gbps network adapter Is this system a good choice for hosting the lab environment you plan to build? No. When guest systems need network access, best practice suggests that the Windows Server 2016 host system should use the Desktop Experience deployment. Yes. This system meets the best practice suggestions for hosting guest systems that need network access. No. When guest systems need network access, best practice suggests that the host system should use Windows Server 2016 Datacenter edition. No. When guest systems need network access, best practice suggests that a host should have its own network adapter and an additional network adapter for every four virtual machines.

No. When guest systems need network access, best practice suggests that a host should have its own network adapter and an additional network adapter for every four virtual machines. Explanation No. When guest systems need network access, best practice suggests that a host should have its own network adapter and an additional network adapter for every four virtual machines. This host system only has one network adapter, which is likely to become a bottleneck if the virtual machines generate a lot of network traffic. Hyper-V is supported by both Windows Server 2016 Datacenter edition and Standard edition. Best practice suggests that a host system should use the Server Core deployment.

19. You want to implement Hyper-V so you can create a lab environment that mirrors your production network for testing applications before deploying them into your production environment. You're planning on having four virtual Windows servers in this lab environment. You plan to use hardware that you already have on hand to create your first Hyper-V host system. You have an unused system with the following specifications and OS installed: • A 64-bit processor with second-level address translation (SLAT). • VM monitor mode extensions. • UEFI that supports virtualization with the following features: • Hardware-assisted virtualization with Intel VT. • Data Execution Prevention (DEP) enabled with Intel Execute Disable Bit (XD). • 4 GB RAM. • Windows Server 2016 Standard Edition with the Desktop Experience deployment. Will this system allow you to create your lab environment? No. You need to use a Windows Server 2016 Standard or Datacenter Edition with the Server Core deployment. No. You need Windows Server 2016 Datacenter Edition to support Hyper-V. No. You need more RAM to support four virtual machines. Yes. This system meets the minimum requirements for a Hyper-V host.

No. You need more RAM to support four virtual machines. Explanation This system does not meet the needs you have in creating a lab environment; you need more RAM to support four virtual machines. The system does meet the minimum requirements for creating a Hyper-V host system, but you also need enough physical RAM to support multiple virtual machines on top of the RAM needed by the host machine. Each virtual machine you create will need memory to be allocated from the physical machine's RAM for use by the virtual machine.

18. Virtualization offers several advantages for server administrators. As an administrator, your job can be made easier because of the several tasks you can perform on or with a virtual machine instead of on a physical machine. The advantages of virtualization can be organized into the categories listed on the below. Drag the advantage category on the left to the task that matches it on the right. (Each category can be used once, more than once, or not at all.) Move many physical servers onto a few host servers with many virtual machines. Verify updates and patches before rolling them out into the production environment. Create a sandboxed environment where malware can be executed with minimal risk to equipment and software. Move virtual machines between hypervisor hosts as needed. Create a lab environment that mirrors your production network to see how an application runs before putting it into production. Migrate an older operating system off of aging hardware and into a virtual machine. Server Consolidation Server Consolidation Testing Functions Flexibility Isolation Testing Functions

Server Consolidation-Move many physical servers onto a few host servers with many virtual machines. Testing Functions-Verify updates and patches before rolling them out into the production environment. Isolation-Create a sandboxed environment where malware can be executed with minimal risk to equipment and software. Flexibility-Move virtual machines between hypervisor hosts as needed. Testing Functions-Create a lab environment that mirrors your production network to see how an application runs before putting it into production. Server Consolidation-Migrate an older operating system off of aging hardware and into a virtual machine. Explanation Advantages of virtualization are: • Flexibility: virtual machines can be given network access, and other network devices will consider them to be real physical machines. • Virtual machines should have the latest service packs and patches, just like physical machines. • Virtual machines should be hardened, just like physical machines. • Virtual machines can be connected to the production network by creating a bridged (external) virtual switch. • Because they are self-contained, virtual machines can be easily moved between hypervisor hosts as needed. • Testing Functions: virtual machines can be configured in a lab environment that mirrors your production network for testing purposes. This lab environment can be used to: • Test applications before installing them on production systems. • Test updates and patches before rolling them out into the production environment. • Test security controls to verify that they are working as designed. • Server Consolidation: server consolidation allows you to move multiple physical servers onto just a few physical servers with many virtual machines. Physical-to-virtual migration (P2V) is moving an older operating system off of aging hardware and into a virtual machine. Consolidating servers: • Require fewer physical computers. • Reduce power consumption. • Increase physical server resource utilization. • Increase administrative efficiency. • Aid resolving incompatibility issues. • Isolation: a virtual machine can be isolated from the physical network to allow testing to be performed without impacting the production environment. This is called sandboxing. • Sandboxed virtual machines offer an environment where malware can be executed with minimal risk to equipment and software. • Virtual machines that are isolated in this fashion are isolated from many kinds of security threats. • To allow the virtual machines to communicate with each other while isolating them from the production network, perform the following: • Create a new virtual switch configured for host-only (internal) networking. • Connect the virtual network interfaces in the virtual machines to the virtual switch.

1. You want to use Hyper-V to create two virtual machines that each use a common parent installation. Listed below are the steps necessary to complete the configuration. Drag each required step from the list on the left to the spaces on the right. Use only the necessary steps to complete the configuration. 1) Step 1 2) Step 2 3) Step 3 4) Step 4 5) Step 5 6) Step 6. a) Create the virtual machine(s). b) Create one fixed disk c) Create two differencing disks. d) Make the disk(s) read only. e) Create the virtual machine(s). f) Install the operating system.

Step 1-b) Create one fixed disk. Step 2-a) Create the virtual machine(s). Step 3-f) Install the operating system. Step 4-d) Make the disk(s) read only. Step 5-c) Create two differencing disks. Step 6-e) Create the virtual machine(s). Explanation To create parent and child virtual machines: 1. Create a single fixed disk. This disk will be used by the parent virtual machine. 2. Create a virtual machine using the fixed disk. 3. Install the operating system. 4. Mark the fixed disk as read only. This should be marked as read only before you create the differencing disks. 5. Create two differencing disks. 6. Create two virtual machines using the differencing disks. You do not need to install the operating system or integration services on the child machines, as they will use the installation from the parent machine.

25. You currently manage a virtual machine named VM18 that has been installed on the Srv5 physical server. The virtual machine runs Windows Server and a custom application. You receive an update to the application. You want to save the current state so if the update causes any problems, you can easily revert back to the state before the update was installed. What should you do? Take a snapshot of the virtual machine. Make a backup of all of the files that are part of the virtual machine. Create a differencing disk from the current virtual hard disk and then archive the differencing disk. Make a copy of the virtual machine configuration file.

Take a snapshot of the virtual machine. Explanation A snapshot is a point-in-time capture of a virtual machine. When you take a snapshot, the current contents of memory are recorded, and a new virtual hard disk file is created. You can easily revert to the previous configuration by applying a snapshot. Applying a snapshot is a faster recovery method than restoring from backup. Saving the virtual machine configuration file will not save data saved on the hard disk or in the virtual machine's memory. While snapshots use differencing disks, the current configuration of the system is not saved in the differencing disk—only changes are saved to the differencing disk.

17. Virtualization is the ability to install and run multiple operating systems concurrently on a single physical machine. Windows virtualization includes several standard components. Match the component on the top to the appropriate description on the bottom. (Each component can be used once, more than once, or not at all.) Virtual Hard Disk (VHD) Hypervisor Virtual Machine Physical Machine A file that resides within the host operating system and serves a storage device for the virtual machine. A thin layer of software that resides between the guest operating system and the hardware. The guest operating system that is a software implementation of a computer that executes programs.

Explanation Virtualization is the ability to install and run multiple operating systems concurrently on a single physical machine. Virtualization typically includes the following components: • Physical Machine: also known as a host operating system, the physical machine the actual hardware in place on the machine, such as the hard disk drive(s), optical drive, RAM, and motherboard. • Virtual Machine: also known as the guest operating system, the virtual machine is a software implementation of a computer that executes programs like a physical machine. The virtual machine appears to be a self-contained and autonomous system. • Virtual Hard Disk (VHD): a file that is created within the host operating system and *EXPLINATION NEEDS EDITING* s•imHuylpaetersviasohra:rda disik flaoyr etrheofvsirotuftawl amreacthiante resides between the guest operating system(s) and the hardware.

11. The Srv1 server runs Hyper-V and has several virtual servers installed. You would like to copy the VM4 virtual machine and create two new virtual machines running on Srv1. You are using the Hyper-V Manager console and want to complete the task with as little effort as possible. Which of the following procedures will let you create two virtual machines from the original VM4? a) Export VM4 to the C:\Export folder. Copy the C:\Export folder to C:\Export2. Import the configuration using C:\Export as the path. Import the configuration again using C:\Export2 as the path. b) Export VM4 to the C:\Export folder. Import the configuration choosing C:\Export\VM4 as the path. Import the configuration a second time. c) Export VM4 to the C:\Export folder. Import the configuration choosing C:\Export as the path. Import the configuration a second time. d) Export VM4 to the C:\Export folder. Copy the C:\Export folder to C:\Export2. Import the configuration using C:\Export\VM4 as the path. Import the configuration again using C:\Export2\VM4 as the path.

a) Export VM4 to the C:\Export folder. Copy the C:\Export folder to C:\Export2. Import the configuration using C:\Export\VM4 as the path. Import the configuration again using C:\Export2\VM4 as the path. Explanation Use the Export and Import features in Hyper-V Manager to simplify moving virtual machines. Before importing the files, make a copy of the exported files if you need to import the files more than once. During the import, select the sub-folder that corresponds to the server name (C:\Export\VM4 or C:\Export2\VM4 in this scenario). Selecting the C:\Export or C:\Export2 folder will cause the import to fail. If you want to import the same set of files multiple times to create multiple virtual machines, you must make a copy of those files. Because the import function modifies the virtual machine files, once a set of files has been imported, the same files cannot be imported again.

2. The Srv1 server runs Hyper-V and has several virtual servers installed. Currently, most virtual servers are used for testing purposes. The physical system is running out of memory because of all of the virtual machines that are currently active. You want to stop three virtual machines to free up system resources. You want to stop the virtual machines so that all open applications are still open and running when they start again. What should you do? a) Save the virtual machine. b) Take a snapshot. c) Shut down the virtual machine. d) Turn off the virtual machine.

a) Save the virtual machine. Explanation The Save option suspends or pauses the virtual machine. This option is like using the Hibernate or Sleep options in the virtual machine. When you restart the machine, it is restored to its current active state. The Shut Down option shuts down the virtual machine as if you had chosen Shut Down from the Start menu. When you restart the virtual machine, it will reboot. The Turn Off option closes the virtual machine without saving any information. This option is like cutting the power to the virtual machine and should be used with caution, as it can make the operating system unstable. A snapshot saves the current machine state, but does not shut down the system.

5. Which Hyper-V feature found in Windows Server provides temporary memory that allows a virtual machine to restart even when there is not enough physical memory available? a) Smart Paging b) Dynamic Memory c) Resource Metering d) Resource Control

a) Smart Paging Explanation Smart Paging allows a virtual machine to restart when there is not enough available memory to restart the virtual machine. It does this by implementing a temporary page file on the hypervisor host's hard disk drive. Smart Paging is used if the following conditions are true: • The virtual machine is being restarted. • There is no available physical memory. • No memory can be reclaimed from other virtual machines on the host. Dynamic Memory allows you to specify a range of memory that can be allocated to each virtual machine. Resource Metering measures the usage of assigned resources on a virtual machine. Resource Control allows you to configure each VM's usage of host resources.

3. You are the network administrator for northsim.com. The network consists of a single Active Directory domain. The company has offices throughout the United States and internationally. You have two Windows servers named HV1 and HV2 that are located in the New York office. Both servers have the Hyper-V role installed. Both servers have quad core processors and 16 GB of RAM. HV1 hosts two virtual machines named APP1 and APP2: • APP1 hosts an application used heavily by users in New York. • APP2 hosts an application used heavily by users in London. During the day, you observe poor performance on APP1 due to a shortage of memory. During the evening, APP1 performs fine. However, APP2 experiences poor performance during peak business hours in London due to a shortage of memory. There are no empty slots to add memory to the server, and management does not have budget to upgrade HV1 for at least 6 months. You need to improve performance for APP1 and APP2 using the least amount of administrative effort. What should you do? a) Install Integration Services in APP1 and APP2. b) Implement Dynamic Memory in the properties of APP1 and APP2. c) Increase the size of the page file on HV1. d) Implement a failover cluster using HV1 and HV2. Make HV1 the active member forAPP1. Make HV2 the active member for APP2.

b) Implement Dynamic Memory in the properties of APP1 and APP2. Explanation Implement Dynamic Memory in the properties of APP1 and APP2. When you implement Dynamic Memory, Hyper-V treats memory as a shared resource that can be allocated automatically among running virtual machines. Dynamic Memory adjusts the amount of memory available to a virtual machine based on changes in memory demand and values that you specify. In this example, there is not enough RAM in the server to accommodate both APP1 and APP2. However, since both virtual machines have different peak times, enabling Dynamic Memory would allow the server to allocate more memory to each virtual machine during its peak hours. Integration Services provides a number of features that allow the virtual machine to interact with the host, including support for time synchronization, a heartbeat used to detect when a guest operating system becomes unresponsive, and drivers to support network and video integration. This would generally be used to address a problem with the video driver or network driver inside the virtual machine or to provide expanded connectivity between the host machine and the virtual machine. Implementing a failover cluster and moving one of the virtual machines could potentially resolve the problem if HV2 has enough spare resources to accommodate one of the virtual machines. However, this is a lot of effort based on too little information about HV2. Generally, a failover cluster is used to provide fault tolerance in case one of the servers fails, which was not part of the objective set forth in this question. Increasing the size of the paging file on HV1 may make more virtual memory available to HV1. However, the virtual memory in use on the host is not made available to the virtual machines. Their memory is allocated from the physical memory on the host, so this would not improve performance in the virtual machines.

6. You need to view resource usage for a Hyper-V virtual machine named AccServer that is running on a Windows Server system. Which PowerShell command can you use to do this? a) Checkpoint-VM -VMName AccServer b) Measure-VM -VMName AccServer c) Get-VMIntegrationService AccServer d) Get-VM AccServer

b) Measure-VM -VMName AccServer Explanation Resource metering measures the actual usage of assigned resources in a virtual machine, such as CPU, memory, and disk. To view resource usage at the PowerShell prompt, you use the Measure-VM cmdlet followed by the name of the virtual machine you wish to analyze. In this example, you would open PowerShell and enter Measure-VM -VMName AccServer. The Get-VM cmdlet displays the virtual machine status. The Checkpoint-VM cmdlet creates a snapshot of the virtual machine. The Get-VMIntegrationService AccServer cmdlet displays the status of integration services installed on the virtual machine.

14. The sales department in your organization needs you to deploy a new web-based contact management application for them. The application runs only on Windows Server 2008 R2. You don't have a budget for new hardware, but you do have unused licenses available for this operating system. You decide to create a new virtual machine on an existing Windows Server 2016 Hyper-V host in your network. You plan to configure the virtual machine as follows: • Specify a generation 2 virtual machine. • Create a 200 GB virtual SCSI hard disk (VHDX) for the system volume. • Create a 1 TB virtual SCSI hard disk (VHDX) for application data. • Create a virtual SCSI optical drive. • Install a 64-bit version of Windows Server 2008 R2. Will this configuration work? a) No. Generation 2 virtual machines do not support SCSI virtual optical drives. b) No. Windows Server 2008 R2 is not supported in generation 2 virtual machines. c) No. The system (boot) drive must be an IDE virtual disk. d) Yes. This configuration meets all requirements. e) No. Generation 2 virtual machines do not support VHDX virtual disk files

b) No. Windows Server 2008 R2 is not supported in generation 2 virtual machines.. Explanation Windows Server 2008 R2 cannot be installed in a generation 2 Hyper-V virtual machine. Only the following guest operating systems are supported on generation 2 virtual machines: • Windows Server 2012 and later • 64-bit versions of Windows 8 and later Generation 2 virtual machines support booting from SCSI virtual hard disks. Virtual SCSI optical drives are also supported. Generation 2 virtual machines only support VHDX virtual disk files. VHD files are not supported.

9. You are the network administrator for Corpnet.com. You have several virtual machines hosted on a VMware platform. You have installed a new Windows server that has the Hyper-V role installed. You need to migrate the VMware virtual machines to Hyper-V. What should you do? a) Use the Disk2VHD tool. b) Use the Microsoft Virtual Machine Converter (MVMC) tool. c) Use the Application Compatibility toolkit (ACT). d) Use the Microsoft Assessment and Planning (MAP) toolkit.

b) Use the Microsoft Virtual Machine Converter (MVMC) tool. Explanation You should use the Microsoft Virtual Machine Converter (MVMC) tool. The Microsoft Virtual Machine Converter (MVMC) tool is a free tool that can be used to convert VMware-based virtual machines and virtual disks to Hyper-V-based virtual machines and virtual hard disks. The Microsoft Assessment and Planning (MAP) toolkit can be used to scan a network to determine which machines can be upgraded and/or converted to virtual machines. The Application Compatibility Toolkit (ACT) can be used to assess applications and determine whether they will be compatible with particular versions of the operating system and provides resources to help resolve incompatibility issues. The Disk2VHD tool can be used to convert an operating on a physical computer into a virtual machine.

12. You have exported a virtual machine to a USB flash drive. You have just installed a new Hyper-V host, and you intend to build a lab environment consisting of several VMs on it. You plug the flash drive into the new host server and begin the import process. Partway through the process, the Import Virtual Machine wizard gives you several import types to choose from. Which of the following import types should you choose? a) Register the virtual machine in place (use the existing unique ID) b) Restore the virtual machine (use the existing unique ID) c) Copy the virtual machine (create a new unique ID)

c) Copy the virtual machine (create a new unique ID) Explanation You should select the Copy the virtual machine (create a new unique ID) option. This option essentially creates a new virtual machine on this new host system. The VM will be named the same and have the same IP address settings, but its UID will be different than the one on the source system. If you select the Register the virtual machine in place (use the existing unique ID) option, the virtual machine will run from the place it is in, which is not ideal because it is currently stored on the USB flash drive, and you want to build a lab environment on this host system. You cannot select the Restore the virtual machine (use the existing unique ID) option because this machine was never on this new VM host system, so it can't be restored to it.

7. You need to view resource usage for a Hyper-V virtual machine named AccServer that is running on a Windows Server system. Before you can actually retrieve resource usage information, you first need to turn resource metering on for the virtual machine. Which PowerShell command can you use to do this? a) Enable-VMEventing AccServer b) Measure-VM -VMName AccServer c) Enable-VMResourceMetering -VMName AccServer d) Get-VMBios AccServer

c) Enable-VMResourceMetering -VMName AccServer Explanation To actually view resource usage at the PowerShell prompt after resource metering has been enabled, you use the Measure-VM cmdlet. The Get-VMBios cmdlet retrieves the BIOS configuration of the virtual machine. The Enable-VMEventing cmdlet enables automatic refresh of Hyper-V information in the current Windows PowerShell session.

10. You are the network administrator for Corpnet.com. You have two Windows servers named HV1 and HV2. Both servers have the Hyper-V role installed. HV1 has an Intel processor, and HV2 has an AMD processor. HV2 hosts a virtual machine named VM1. You build another server named HV3 and install the Hyper-V role. HV3 has an Intel processor. You need to move VM1 from HV2 to HV3 with the least amount of downtime. What should you do? a) Perform a live migration. b) Create a replica of VM1 on HV3 and then execute a planned failover. c) Export VM1 on HV2 and then import it on HV3. d) Perform a quick migration.

c) Export VM1 on HV2 and then import it on HV3. Explanation You should Export VM1 on HV2 and then import it on HV3. Although an export and import of a virtual machine is not as fast as a quick migration or a live migration, both of these options require that the source host and the destination host use processors from the same manufacturer. Since HV2 has an AMD processor and HV3 has an Intel processor, you will need to transfer the virtual machine using an export and import. You use Hyper-V Replicas to provide fault tolerance for a virtual machine in the event that the active host fails.

15. The sales department in your organization needs you to deploy a new web-based contact management application for them. The application runs on Windows Server 2012. You don't have a budget for new hardware, but you do have unused licenses available for this operating system. You decide to create a new virtual machine on an existing Windows Server 2016 Hyper-V host in your network. You created the virtual machine as follows: • Generation 1 virtual machine • 200 GB virtual IDE hard disk (VHDX) for the system volume • 1 TB virtual SCSI hard disk (VHDX) for application data • IDE virtual optical drive • Windows Server 2012 After several months in production, you decide that you would like to implement the Secure Boot feature in the virtual machine. You know this feature is only available on generation 2 virtual machines, so you decide to upgrade the virtual machine and then implement the new feature. Will this configuration work? a) No. The system (boot) drive must be a SCSI virtual disk in a generation 2 virtual machine. b) No. Generation 2 virtual machines only support Windows Server 2012 R2 or Windows 8.1 as the guest operating system. c) No. You cannot change the generation of a virtual machine after it has been created. d) No. Generation 2 virtual machines do not support VHDX virtual disk files. e) Yes. This configuration meets all requirements.

c) No. You cannot change the generation of a virtual machine after it has been created. Explanation You cannot change the generation of a virtual machine once it has been created. In this scenario, a new generation 2 virtual machine would need to be created. Then the application and its data would need to be migrated from the original virtual machine to the new virtual machine.

8. You are the network administrator for Corpnet.com. The network has two servers that run Windows Server. They are named HV1 and HV2. Both servers are running the Hyper-V role and are members of a cluster named Cluster1. HV1 hosts a virtual machine running a Windows server named VM1. HV1 is running low on space. You would like to transfer the .VHD file for VM1 to HV2 while you requisition additional space. VM1 must remain available while space is added to HV1. What should you do? a) Perform a live migration. b) Perform a quick migration. c) Enable virtual machine monitoring. d) Perform a storage migration.

d) Perform a storage migration. Explanation You should perform a storage migration. Windows Server allows you to move virtual machine storage while the virtual machine is still running. This is called a storage migration. Live migrations can be planned or unplanned. In the event of an unplanned live migration, the virtual machine is automatically transferred to another Hyper-V server when the server becomes unavailable. When you initiate a planned live migration, the cluster copies the memory being used by the virtual machine from the current node to another node so that the memory and state information is already in place for the virtual machine. Quick migrations also copy the memory, but cannot be used for an unplanned migration. Virtual machine monitoring is used to monitor services in the guest operating system and respond to outages.
