The questions is about NIC and not IP addresses:... thus, one NIC can have 1 public and one private ip address. the answer is 5 NIC and 1 NSG. An Azure Virtual Machine (VM) has one or more network interfaces (NIC) attached to it. Any NIC can have one or more static or dynamic public and private IP addresses assigned to it.

First Box : Minimum number of network interfaces (5, 10, 15, 20) Second Box : Minimum number of network security groups (1, 2, 5, 10) So the answers are : First box : 5 (NIC) Second box : 1 (NSG) Reason : 1st 5 network interfaces since 1 network interface can have both public and private ip addresses. 2nd 1 NSG

By Default Inbound and Outbound Security Rules are same for all VMs. Therefore, if default rules suffice, then there is no need for NSG at all. 5 NICs and 1 NSG for non-default Inbound and Outbound Rules 5 Nics and 0 NSG for default Inbound and Outbound Rules.
