Answers
D.
Place the security appliance in the public subnet with the internet gateway
Suggested answer: C

Explanation:

Each EC2 instance performs source/destination checks by default. This means that the instance must be the source or destination of any traffic it sends or receives. In this case virtual security appliance instance must be able to send and receive traffic when the source or destination is not itself.

Therefore, you must disable source/destination checks on the NAT instance."
