D is the correct answer

Answer A

D https://blogs.oracle.com/cloud-infrastructure/post/tutorial-automatically-setup-a-nat-instance-in-oracle-cloud-infrastructure-with-terraform

A is the answer

fhoyos - I agree all documentation point towards NAT GW. So we are saying 'A'

I will go with D because Nat instance is cheaper than NAT Gateway. (https://dzone.com/articles/nat-instance-vs-nat-gateway) https://www.kabisa.nl/tech/cost-saving-with-nat-instances/

I would say 'A' as it mentions cost considering. A LB costs. I would go with A.

D is wrong, the right answer is A. Nat Gateway + route table
