You need to achieve this goal by using the least amount of administrative effort

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.

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

The link above is no longer working – use:
https://docs.microsoft.com/en-us/azure/virtual-network/virtual-network-ip-addresses-overview-arm

There are two methods in which an IP address is allocated to a public IP resource – dynamic or static… To ensure the IP address for the associated resource remains the same, you can set the allocation method explicitly to static.

…assign the virtual machine a specific IP address.
