You manage an Azure virtual network that hosts 15 virtual machines (VMs) on a single subnet
which is used for testing a line of business (LOB) application. The application is deployed to a VM
named TestWebServiceVM. You need to ensure that TestWebServiceVM always starts by using

the same IP address. You need to achieve this goal by using the least amount of administrative
effort. What should you do?

A.
Use the Management Portal to configure TestWebServiceVM.

B.
Use RDP to configure TestWebServiceVM.

C.
Run the Set-AzureStaticVNetIP PowerShell cmdlet.

D.
Run the Get-AzureReservedIP PowerShell cmdlet.

Explanation:
Specify a static internal IP for a previously created VM. If you want to set a static IP address for a
VM that you previously created, you can do so by using the following cmdlets. If you already set an
IP address for the VM and you want to change it to a different IP address, you’ll need to remove
the existing static IP address before running these cmdlets. See the instructions below to remove
a static IP. For this procedure, you’ll use the Update-AzureVM cmdlet. The Update-AzureVM cmdlet
restarts the VM as part of the update process. The DIP that you specify will be assigned after the
VM restarts. In this example, we set the IP address for VM2, which is located in cloud service
StaticDemo.
Get-AzureVM -ServiceName StaticDemo -Name VM2 | Set-AzureStaticVNetIP -IPAddress
192.168.4.7 | Update-AzureVM
