You have several virtual machines (VMs) that run in Azure. You also have a single System Center
2012 R2 Configuration Manager (SCCM) primary site on-premises.
You have the following requirements:
All VMs must run on the same virtual network.
Network traffic must be minimized between the on-premises datacenter and Azure.
The solution minimize complexity.
You need to use SCCM to collect inventory and deploy software to Azure VMs.
What should you do first?

A.
Configure client push for the Azure virtual network.

B.
Enable and configure Operations Insights in Azure.

C.
Install a cloud distribution point on an Azure VM.

D.
Install a secondary site underneath the primary site onto an Azure VM.

Explanation:
Cloud-based distribution Point, a Configuration Manager Site System Role in the Cloud
Much of the Configuration Manager topology is made up of distribution points, they are very helpful
in many situations where bandwidth and geographical separation are the facts of life, but also hard
to manage if you have hundreds or even thousands of them.
This feature started with the vision that it makes perfect sense to have big distribution points in the
Windows Azure cloud where one should not worry about things like (but not limited to) size,
performance, reliability, security, access from all around the world, hardware/software update
issues etc.
Note: Content management in System Center 2012 Configuration Manager provides the tools for
you to manage content files for applications, packages, software updates, and operating system
deployment. Configuration Manager uses distribution points to store files that are required for
software to run on client computers. These distribution points function as distribution centers for
the content files and let users download and run the software. Clients must have access to at least
one distribution point from which they can download the files.
