Explanation
Here are the steps and explanations for ensuring that the storage34280945 storage account will only accept connections from hosts on VNET1:
To restrict network access to your storage account, you need to configure the Azure Storage firewall and virtual network settings for your storage account. You can do this in the Azure portal by selecting your storage account and then selecting Networking under Settings1.
On the Networking page, select Firewalls and virtual networks, and then select Selected networks under Allow access from1. This will block all access to your storage account except from the networks or resources that you specify.
Under Virtual networks, select + Add existing virtual network. Then select VNET1 from the list of virtual networks and select the subnet that contains the hosts that you want to allow access to your storage account1. This will enable a service endpoint for Storage in the subnet and configure a virtual network rule for that subnet through the Azure storage firewall2.
Select Add to add the virtual network and subnet to your storage account1.
Select Save to apply your changes1.

VNet 1 will get the default from BGP and propagate it to VNET 2 and 3

Existing Environment:
Azure Network Infrastructure
Contoso has an Azure Active Directory (Azure AD) tenant named contoso.com.
The Azure subscription contains the virtual networks shown in the following table.

Vnet1 contains a virtual network gateway named GW1.
Azure Virtual Machines
The Azure subscription contains virtual machines that run Windows Server 2019 as shown in the following table.

The NSGs are associated to the network interfaces on the virtual machines. Each NSG has one custom security rule that allows RDP connections from the internet. The firewall on each virtual machine allows ICMP traffic.
An application security group named ASG1 is associated to the network interface of VM1.
Azure Private DNS Zones
The Azure subscription contains the Azure private DNS zones shown in the following table.

Zone1.contoso.com has the virtual network links shown in the following table.

Other Azure Resources
The Azure subscription contains additional resources as shown in the following table.

Requirements:
Virtual Network Requirements
Contoso has the following virtual networks requirements:
* Create a virtual network named Vnet6 in West US that will contain the following resources and configurations:
Two container groups that connect to Vnet6
Three virtual machines that connect to Vnet6
Allow VPN connections to be established to Vnet6
Allow the resources in Vnet6 to access KeyVault1, DB1, and Vnet1 over the Microsoft backbone network
* The virtual machines in Vnet4 and Vnet5 must be able to communicate over the Microsoft backbone network.
* A virtual machine named VM-Analyze will be deployed to Subnet1. VM-Analyze must inspect the outbound network traffic from Subnet2 to the internet.
Network Security Requirements
Contoso has the following network security requirements:
* Configure Azure Active Directory (Azure AD) authentication for Point-to-Site (P2S) VPN users.
* Enable NSG flow logs for NSG3 and NSG4.
* Create an NSG named NSG10 that will be associated to Vnet1/Subnet1 and will have the custom inbound security rules shown in the following table.

* Create an NSG named NSG11 that will be associated to Vnet1/Subnet2 and will have the custom outbound security rules shown in the following table.
