A user has created a VPC with CIDR 20.0.0.0/16. The user has created public and VPN only subnets along with hardware
VPN access to connect to the user’s datacenter. The user wants to make so that all traffic coming to the public subnet
follows the organization’s proxy policy. How can the user make this happen?

A.
Setting up a NAT with the proxy protocol and configure that the public subnet receives traffic from NAT

B.
Settin up a proxy policy in the internet gateway connected with the public subnet

C.
It is not possible to setup the proxy policy for a public subnet

D.
Setting the route table and security group of the public subnet which receives traffic from a virtual private gateway

Explanation:
The user can create subnets within a VPC. If the user wants to connect to VPC from his own data centre, he can setup
public and VPN only subnets which uses hardware VPN access to connect with his data centre. When the user has
configured this setup, it will update the main route table used with the VPN-only subnet, create a custom route table and
associate it with the public subnet. It also creates an internet gateway for the public subnet. By default the internet traffic
of the VPN subnet is routed to a virtual private gateway while the internet traffic of the public subnet is routed through the
internet gateway. The user can set up the route and security group rules. These rules enable the traffic to come from the
organization’s network over the virtual private gateway to the public subnet to allow proxy settings on that public subnet.
