[RFC2544] explains that this range was assigned to minimize the chance of conflict in case a  testing device were to be accidentally connected to part of the Internet. Packets with source addresses from this range are not meant to be forwarded across the Internet.

  • [reflection.assembly]::loadwithpartialname("System.Windows.Forms")
  • Add-Assembly -AssemblyName System.Windows.Forms
  • New-Object -TypeName System.Reflection.Assembly(System.Windows.Forms)
  • New-Assembly -AssemblyName "WPF" 

In Windows PowerShell, which of the following is a way you can load WPF for the creation of GUI interfaces in your scripts?

 EXPLANATION

You would call the System.Reflection.Assembly object, then load the WPF assembly, "System.Windows.Forms" with the method LoadWithPartialName. This allows you to then add objects from the System.Windows.Forms assembly, like Form or Button.

What is the codenamed for the Microsoft Hyper-V?

 

EXPLANATION

Microsoft Hyper-V, codenamed Viridian and formerly known as Windows Server Virtualization, is a native hypervisor; it can create virtual machines on x86-64 systems running Windows. Starting with Windows 8, Hyper-V supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks.

Hyper-V was first released alongside Windows Server 2008, and has been available without charge for all the Windows Server and some client operating systems since.

Hyper-V is also available on the Xbox One, in which it would launch both Xbox OS and Windows 10.
