You have an on-premises network that uses an IP address space of 172.16.0.0/16.
You plan to deploy 25 virtual machines to a new Azure subscription.
You identify the following technical requirements:
All Azure virtual machines must be placed on the same subnet named Subnet1.
All the Azure virtual machines must be able to communicate with all on-premises servers.
The servers must be able to communicate between the on-premises network and Azure by using a site-to-site VPN.
You need to recommend a subnet design that meets the technical requirements.
What should you include in the recommendation?
