Explanation:

Box 1: VM2, VM3 and VM4.
VM1 is in VNet1/Subnet1. VNet1 is peered with VNet2 and VNet3.
There are no NSGs blocking outbound ICMP from VNet1. There are no NSGs blocking inbound ICMP to VNet1/Subnet2, VNet2 or VNet3. Therefore, VM1 can ping VM2 in VNet1/Subnet2, VM3 in VNet2 and VM4 in VNet3.
Box 2:
VM4 is in VNet3. VNet3 is peered with VNet1 and VNet2. There are no NSGs blocking outbound ICMP from VNet3. There are no NSGs blocking inbound ICMP to VNet1/Subnet1, VNet1/Subnet2 or VNet2 from VNet3 (NSG10 blocks inbound ICMP from VNet4 but not from VNet3). Therefore, VM4 can ping VM1 in VNet1/Subnet1, VM2 in VNet1/Subnet2 and VM3 in VNet2.

Explanation:
To deploy Azure virtual machines to the France Central region and ensure they are in a network segment with an IP address range of 10.5.1.0/24, follow these steps:
Step-by-Step Solution
Step 1: Create a Virtual Network in France Central
* Navigate to the Azure Portal.
* Search for "Virtual networks" in the search bar and select it.
* Click on "Create".
* Enter the following details:
* Subscription: Select your subscription.
* Resource Group: Select an existing resource group or create a new one.
* Name: Enter a name for the virtual network (e.g., VNet-FranceCentral).
* Region: Select France Central.
* Click on "Next: IP Addresses".
Step 2: Configure the Address Space and Subnet
* In the IP Addresses tab, enter the address space as 10.5.1.0/24.
* Click on "Add subnet".
* Enter the following details:
* Subnet name: Enter a name for the subnet (e.g., Subnet-1).
* Subnet address range: Enter 10.5.1.0/24.
* Click on "Add".
* Click on "Review + create" and then "Create".
Step 3: Deploy Virtual Machines to the Virtual Network
* Navigate to the Azure Portal.
* Search for "Virtual machines" in the search bar and select it.
* Click on "Create" and then "Azure virtual machine".
* Enter the following details:
* Subscription: Select your subscription.
* Resource Group: Select the same resource group used for the virtual network.
* Virtual machine name: Enter a name for the VM.
* Region: Select France Central.
* Image: Select the desired OS image.
* Size: Select the appropriate VM size.
* Click on "Next: Disks", configure the disks as needed, and then click on "Next: Networking".
* In the Networking tab, select the virtual network (VNet-FranceCentral) and subnet (Subnet-1) created earlier.
* Complete the remaining configuration steps and click on "Review + create" and then "Create".
Explanation:
* Virtual Network: A virtual network in Azure allows you to create a logically isolated network that can host your Azure resources.
* Address Space: The address space 10.5.1.0/24 ensures that the VMs are in a specific network segment.
* Subnet: Subnets allow you to segment the virtual network into smaller, manageable sections.
* Region: Deploying the virtual network and VMs in the France Central region ensures that the resources are physically located in that region.
By following these steps, you can ensure that your Azure virtual machines in the France Central region are deployed within the specified IP address range of 10.5.1.0/24.

Virtual network integration depends on a dedicated subnet.
https://docs.microsoft.com/en-us/azure/app-service/overview-vnet-integration#regional-virtual-network- integration For outgoing traffic from Web App to vnet, it will go through Internet, so the cost not the minimum.
The connection between the Private Endpoint and the Web App uses a secure Private Link. Private Endpoint is only used for incoming flows to your Web App. Outgoing flows will not use this Private Endpoint, but you can inject outgoing flows to your network in a different subnet through the VNet integration feature.
