Title: Lesson 8: Quiz
Course: RITA MC - ITNW 1308 > Section: Lesson 8: Configuring Hyper-V

Q: What keeps the parent operating system separate from that of the virtual machines that are running on that host?
- Hyper-V
- The Hypervisor
- The SLAT processor
- The dynamic memory manager
A: The Hypervisor
Feedback: The Hypervisor keeps the host or parent operating system separate from all the virtual machines installed. This allows for the installation and running of multiple child operating systems as separate and secure virtual machines, all within one physical computer.

Q: Before Hyper-V can be used, there are several requirements that must be met. Which of these is not one of those requirements? (Choose all that apply.)
- Windows 8.1 Enterprise edition (32-bit)
- 4 GB RAM
- Second Level Address Translation (SLAT) processor
- Rapid Virtualization Indexing (RVI) BIOS
A: Windows 8.1 Enterprise edition (32-bit); Rapid Virtualization Indexing (RVI) BIOS
Feedback: The requirements for Hyper-V are: - Windows 8.1 Pro or Enterprise edition (64-bit) - Second Level Address Translation (SLAT) processor - 4 GB RAM

Q: What PowerShell cmdlet can you use to enable Hyper-V?
- Add-WindowsOptionalFeature –FeatureName Microsoft-Hyper-V-all
- Enable-WindowsOptionalFeature –FeatureName Microsoft-Hyper-V-all
- Start-WindowsOptionalFeature -online –FeatureName Microsoft-Hyper-V
- Enable-WindowsOptionalFeature -online –FeatureName Microsoft-Hyper-V-all
A: Enable-WindowsOptionalFeature -online –FeatureName Microsoft-Hyper-V-all
Feedback: You will need to use the Enable-WindowsOptionalFeature -online –FeatureName Microsoft-Hyper-V-all cmdlet to enable Hyper-V.

Q: What Hyper-V feature helps you use physical memory more efficiently for your VMs?
- Memory Manager
- Dynamic Memory
- Memory Allocation
- Dynamic Mapper
A: Dynamic Memory
Feedback: Dynamic Memory is a Hyper-V feature that helps you use physical memory more efficiently. With Dynamic Memory, Hyper-V treats memory as a shared resource that can be reallocated 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. The Dynamic Memory feature allows memory to be adjusted between VMs even when they are switched on. As a result, Hyper-V can distribute memory more efficiently among the running virtual machines configured with Dynamic Memory. Depending on factors such as workload, this efficiency can make it possible to run more virtual machines at the same time on one physical computer.

Q: How many VMs can you install on Windows 8.1 Enterprise before you need to start acquiring licenses?
- 0
- 1
- 2
- 4
A: 0
Feedback: Windows 8.1 does not come with any virtualization rights. This is different from Hyper-V on Windows Server. Every virtual machine you create using a Windows 8.1 Hyper-V environment needs a valid end user license for the operating system you install on it.

Q: Checkpoint data files are stored using what file format?
- .vhd
- .vhds
- .shvd
- .avhd
A: .avhd
Feedback: Checkpoint data files are stored as .avhd files. Taking multiple checkpoints can quickly consume storage space. Checkpoint data files usually are located in the same folder as the virtual hard disk by default. Checkpoints are not recommended for use in production environments.

Q: When checkpoints are deleted, when is the space the checkpoint previously consumed on disk released back to the operating system?
- After the next reboot
- After the virtual machine is powered off
- Immediately
- After the virtual machine has updated its configuration files
A: Immediately
Feedback: In this version of Hyper-V, the space taken by the checkpoint is released immediately (prior to this, the virtual machine would have to be stopped before that could happen).

Q: Which Hyper-V virtual switch feature provides protection against a malicious virtual machine attempting to steal IP addresses from other virtual machines?
- ARP/ND Poisoning (spoofing) protection
- Port Access Control Lists (ACLs)
- DHCP Guard protection
- Isolated (private) VLAN
A: ARP/ND Poisoning (spoofing) protection
Feedback: ARP/ND Poisoning (spoofing) protection provides protection against a malicious virtual machine using Address Resolution Protocol (ARP) spoofing to steal IP addresses from other virtual machines. It also provides protection against attacks that can be launched for IPv6 using Neighbor Discovery (ND) spoofing.

Q: Which Hyper-V virtual switch feature allows administrators to create isolated tenant communities?
- Trunk mode to a Virtual Machine
- Port Access Control Lists (ACLs)
- DHCP Guard protection
- Isolated (private) VLAN
A: Isolated (private) VLAN
Feedback: Isolated (private) VLAN enables administrators to segregate traffic on multiple VLANs to more easily establish isolated tenant communities.

Q: There are three types of Hyper-V virtual switches. Which of the following is not one of these types?
- External
- Internal
- Internet
- Private
A: Internet
Feedback: There are three different types of virtual switches: - External: Connects directly to a physical NIC and the virtual machines can communicate with the external network as well as the host computer (if configured to allow that option). Note that a physical NIC can be part of only one external network. - Internal: Allows the virtual machines to communicate together and with the host computer. - Private: Allows the virtual machines to communicate together but not to communicate with the host computer.

Q: How large can a VHD virtual disk be?
- 2 TB
- 64 TB
- 2 PB
- 512 TB
A: 2 TB
Feedback: A VHD file can be as large as 2040 GB (just under 2 TB) in size and was the original format used in the predecessor to Hyper-V (Virtual PC).

Q: The newer VHDX virtual disk file format offers several advantages over the VHD file format. Which of these is not one of those features?
- Improved alignment of the virtual hard disk format to work well on large sector disks
- Protection against data corruption during power failures
- Smaller block sizes for dynamic and differencing disks
- The ability to store custom metadata about the file that the user might want to record, such as the operating system version or patches applied
A: Smaller block sizes for dynamic and differencing disks
Feedback: The following list explains the new features in the VHDX Virtual Hard Disk format. - Support for virtual hard disk storage capacity of up to 64 TB. - Protection against data corruption during power failures by logging updates to the VHDX metadata structures. - Improved alignment of the virtual hard disk format to work well on large sector disks. - Larger block sizes for dynamic and differencing disks, which allows these disks to attune to the needs of the workload. - A 4 KB logical sector virtual disk that allows for increased performance when used by applications and workloads that are designed for 4 KB sectors. - The ability to store custom metadata about the file that the user might want to record, such as the operating system version or patches applied. - Efficiency in representing data (also known as “trim”), which results in smaller file size and allows the underlying physical storage device to reclaim unused space. (Trim requires physical disks directly attached to a virtual machine or SCSI disks, and trim-compatible hardware.)

Q: What is the process by which you move the storage of a VM from one physical server to another without a cluster?
- Storage Migration
- Live Migration
- Quick Migration
- Exporting
A: Storage Migration
Feedback: Storage Migration is the process of moving the storage of a VM from one physical server to another without a cluster.

Q: When performing a Live Migration using the Move the virtual machine’s data by selecting where to move the items option, which of the following advanced options would be the best to choose from to ensure that the folder structure remains the same on the destination server after the LM completes?
- Move the VM’s data automatically
- Move the VM’s data and maintain storage hierarchy
- Move the VM’s hard disks to different locations
- Move the VM’s items to different locations
A: Move the VM’s data automatically
Feedback: The Move the VMs data automatically option maintains the file and folder structure of the source on the destination.
