Server Virtualization with Windows Server Hyper-V and System Center

A company plans to create a Hyper-V environment that will contain three virtual machines (VMs). A limited amount of storage space is available to host the VMs.
The VMs will be configured as follows:

You must maximize disk performance.
You need to recommend a storage solution.
Which type of virtual disk type should you configure for each VM?

HOTSPOT -
You administer the Hyper-V environment for a company. All virtual machines must use dynamic memory and virtual non-uniform memory access (NUMA) settings that are aligned to the underlying hardware.
One virtual machine is misconfigured.
You need to update the misconfigured virtual machine.
In the Settings dialog box for the virtual machine, which two options should you select?
Hot Area:

A company has servers that run Windows Server 2012 R2. The company has one Active Directory Domain Services (AD DS) domain.
A user reports that USB devices are not redirected when he uses the Virtual Machine Connection tool to connect to a virtual machine. USB device redirection works for other users that connect to this VM.
You need to ensure that USB devices are redirected for all users when they connect to this VM.
What should you do?

A company has seven Windows Server 2012 R2 virtual machines (VMs). The VMs are running and are accessible over the network. You plan to copy a large .ISO file from the host server to each of the VMs.
The copy operations must meet the following requirements:
✑ The VMs must remain accessible over the network during the copy operations.
✑ The copy operations must NOT use a network connection.
You need to configure the VMs. What should you do on each VM?

A company has one central data center and five branch offices. Each office has three Hyper-V host servers that run Windows Server 2012 R2 Datacenter edition.
Each branch office has a system administrator. You plan to deploy virtual machines (VMs) that run Windows Server 2012 R2 Standard edition to each branch office.
You have the following requirements:
✑ The VMs must be activated at the branch offices, even if the branch office has no Internet connectivity.
✑ Activation keys must NOT be shared with the branch office administrators.
✑ You must be able to track license usage from the central location, even without access rights to the VMs.
✑ You must be able to verify license compliance and perform real time reporting on license usage from a central location.
You need to configure licensing and activation for the VMs.
