You purchase an Azure subscription. You plan to deploy an application that requires four Azure virtual
machines (VMs). All VMs use Azure Resource Management (ARM) mode.
You need to minimize the time that it takes for VMs to communicate with each other.
What should you do?
A.
Create a multi-site virtual network.
B.
Create a regional virtual network.
C.
Create a site-to-site virtual network.
D.
Add the VMs to the same affinity group.
Explanation:
Affinity groups are no longer available in ARM mode. Regional network is the new way of doing it.https://azure.microsoft.com/en-gb/documentation/articles/virtual-machines-windows-compare-deploymentmodels/
