The correct answer is 192.168.0.0/24; 192.168.1.0/27. The on-premises network uses 172.16.0.0/16, so Azure subnets must use a non-overlapping address space - making 192.168.x.x the correct choice. The VNet address space should be 192.168.0.0/24 (providing enough room for subnets and the required GatewaySubnet), and Subnet1 should…

Question

Drag and Drop Question You have an on-premises network that uses an IP address space of 172.16.0.0/16. You plan to deploy 30 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? To answer, drag the appropriate network addresses to the correct subnets. Each network address may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content. NOTE: Each correct selection is worth one point.

Correct arrangement

  • 192.168.0.0/24
  • 192.168.1.0/27

Explanation

The on-premises network uses 172.16.0.0/16, so Azure subnets must use a non-overlapping address space - making 192.168.x.x the correct choice. The VNet address space should be 192.168.0.0/24 (providing enough room for subnets and the required GatewaySubnet), and Subnet1 should be 192.168.1.0/27, which provides 30 usable host addresses (32 total minus network and broadcast = 30), exactly meeting the requirement of hosting 30 VMs. A /27 is the minimum size that satisfies the 30 VM requirement while keeping the design efficient.
