our plan is to create and configure the following virtual machines:

VM$1$ connects to VNET$1/$Subnet$1$ and allows traffic from TCP port $25.$

VM$2$ connects to VNET$1/$Subnet$1$ and allows traffic from TCP port $80.$

VM$3$ connects to VNET$1/$Subnet$2$ and allows traffic from TCP port $3389.$

VM$4$ connects to VNET$2/$Subnet$0$ and allows traffic from TCP port $8080.$

You need to create the network security groups $($NSGs$)$ to allow only the specified connections.

What is the minimum number of NSGs that you should create?
