The correct answer is B: Private endpoints. Using a private endpoint for your Azure Storage account allows clients on a virtual network (VNet) to securely access data over a Private Link. The private endpoint uses a private IP address from the VNet address space for each storage account service. Network traffic between the clients on the VNet and the storage account traverses over the VNet and a private link on the Microsoft backbone network, eliminating exposure from the public internet. This ensures that all traffic from VM1 to storage1 travels across the Microsoft backbone network.
