   • AAdd a route in the private subnet's route table pointing 0.0.0.0/0 to the internet gateway.
   • BAssign a public IP address to each instance and add a route to the internet gateway in the private subnet's route table.
   • CCreate a NAT gateway in a public subnet, and add a route in the private subnet's route table pointing 0.0.0.0/0 to the NAT gateway.
