The correct answer is 192.168.0.0/24; 192.168.1.0/28. The on-premises network uses 172.16.0.0/16, so Azure subnets must use a non-overlapping address space. 192.168.0.0/24 is chosen for the Virtual Network (VNet) because it provides up to 256 addresses, more than enough for 25 VMs plus Azure-reserved IPs. 192.168.1.0/28 is chosen fo

Question

Drag and Drop Question You have an on-premises network that uses on IP address space of 172.16.0.0/16. You plan to deploy 25 virtual machines to a new azure subscription. You identity the following technical requirements: - All Azure virtual machines must be placed on the same subnet subnet1. - All the Azure virtual machines must be able to communicate with all on premises severs. - 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 subnet. 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
  • 192.168.1.0/28

Explanation

The on-premises network uses 172.16.0.0/16, so Azure subnets must use a non-overlapping address space. 192.168.0.0/24 is chosen for the Virtual Network (VNet) because it provides up to 256 addresses, more than enough for 25 VMs plus Azure-reserved IPs. 192.168.1.0/28 is chosen for the GatewaySubnet required by the Site-to-Site VPN, as /28 provides 16 addresses (11 usable after Azure reserves 5), which is the minimum recommended size for a VPN Gateway subnet. Both subnets fall within a non-overlapping address space, satisfying the requirement that Azure VMs can communicate with on-premises servers without IP conflicts.
