You are implementing Shielded Virtual Machines in an on-premises Hyper-V environment to protect sensitive workloads from fabric administrators. Which TWO infrastructure components are required to support the deployment and health validation of Shielded VMs? (Choose two.)

Select 2 answers

A.Host Guardian Service (HGS)

B.Azure Key Vault

C.Windows Server Update Services (WSUS)

D.Network Controller

E.Guarded Hosts

AnswersA, E

The Host Guardian Service is a central component that provides attestation and key protection services for Shielded VMs. It validates that a Hyper-V host is healthy and authorized before releasing the keys needed to start or migrate a Shielded VM, effectively acting as the security authority for the fabric.

Why this answer

Shielded VMs provide a high level of security by encrypting the VM's data and state, ensuring that only authorized hosts can run them. This requires a complex infrastructure including attestation and key management. Understanding these components is essential for administrators securing highly sensitive data against unauthorized access by high-privileged users.

You are creating a new virtual machine on a Hyper-V host. You decide to use the VHDX file format for the virtual hard disks. Which THREE advantages does VHDX provide over the older VHD format? (Choose three.)

Select 3 answers

A.Support for virtual disks up to 2 TB in size.

B.Support for virtual disks up to 64 TB in size.

C.Protection against data corruption during power failures using a log.

D.Compatibility with Windows Server 2008 R2 hosts.

E.Improved alignment for large sector disks.

AnswersB, C, E

VHDX supports a massive increase in maximum storage capacity, allowing for virtual hard disks up to 64 TB. This capacity is essential for hosting large data volumes, big data applications, and extensive file shares that were previously impossible to manage with the older VHD format's limitations.

Why this answer

The VHDX format was introduced to overcome the limitations of the original VHD format. It offers significant improvements in capacity, performance, and data integrity. Understanding these benefits is crucial for designing modern virtualization storage that can support large enterprise workloads and ensure resilience against unexpected power failures or system crashes.

You need to capture the state of a virtual machine named VM-DEV before applying a series of software updates. You want to ensure that the capture process uses the Volume Shadow Copy Service (VSS) to provide a consistent state of the guest operating system. Which checkpoint type should you use?

A.Standard Checkpoint

B.Production Checkpoint

C.Recovery Point

D.Differential Checkpoint

AnswerB

Production checkpoints use the Volume Shadow Copy Service (VSS) within Windows guests to create a data-consistent image of the VM. This ensures that applications are in a proper state for backup and recovery, making it the recommended choice for production environments where application consistency is a requirement.

Why this answer

Understanding the difference between production and standard checkpoints is vital for Windows Server administrators. Production checkpoints use backup technology inside the guest to create a data-consistent state, whereas standard checkpoints capture the memory state. Choosing the right type prevents application errors and ensures data integrity during recovery operations.

You want to run a Hyper-V virtual machine inside another virtual machine for testing purposes. After creating the guest VM, you find that you cannot install the Hyper-V role within it. Which PowerShell command must you run on the physical host to enable this capability?

A.Enable-WindowsOptionalFeature -FeatureName Microsoft-Hyper-V

B.Set-VMNetworkAdapter -MacAddressSpoofing On

C.Set-VMMemory -DynamicMemoryEnabled $false

D.Set-VMProcessor -ExposeVirtualizationExtensions $true

Why this answer

Nested virtualization allows you to run Hyper-V inside a guest VM, which is invaluable for lab environments and training. This requires exposing the hardware virtualization extensions of the physical CPU to the guest OS. Administrators must know the specific PowerShell cmdlet and parameter required to enable this advanced virtualization feature.

You need to track the average CPU and memory usage for a specific virtual machine over a period of 30 days to assist with capacity planning. Which Hyper-V feature should you enable and use to collect this data?

A.Performance Monitor

B.Azure Monitor

C.Resource Metering

D.Task Manager

Why this answer

Resource metering is a powerful tool for monitoring VM resource consumption over time. It allows administrators to gather data on CPU, memory, disk, and network usage, which is essential for internal chargeback models or infrastructure scaling. Knowing how to enable and query this data via PowerShell is a key administrative task.
