It's A and B, it's not necessary DRG for internet connectivity. DRG is for peering, VPN and Fastconnect

A & D Why do we need egress stateful rule? If it is stateful then it won't be egress.

A) Each public subnet that needs to use the internet gateway must have a route table rule that specifies the gateway as the target. Aunque tenga un RT asociado la subnet si este no tiene una regla referente al IG no va a poder salir. A y B según la pagina. B) The gateway supports connections initiated from within the VCN (egress) and connections initiated from the internet (ingress). NOT D) Despite being true, the question ask only about out connection to internet (egress) https://docs.cloud.oracle.com/en-us/iaas/Content/Network/Tasks/managingIGs.htm

In "None can reach the internet" I understand requesting internet URLs and not receiving an answer, so it would be ingress traffic. So I guess answer is A and D
