C,D
I think it was B & C. If a instance need to communicate with internet , it should be trough NAT Gateway or IGW. VPG for connecting ON-PREM to VPC.
It’s C and D. IGW for internet and VGW for external network (corp). A NAT won’t get you out to the internet without IGW.
It seems like people are confused with NAT instance and NAT Gateway, which are two different things.
Justin is correct,
C.
Internet Gateway {IGW)
D.
Virtual Private Gateway (VGW)
C & D
A – Elastic IP’s are applied to Instances, not VPC
B – NAT is used to forward packets between public and private subnets, not provide connectivity to networks outside of VPC,
NAT is applied to instance also, by disabling src/dest checks.
CD
C,D
A. Elastic IPS (EIP) – Wrong it’s just add a Public IP
B. NAT Gateway (NAT) – Correct!!! “You can use a network address translation (NAT) gateway to enable instances in a private subnet to connect to the Internet or other AWS services, but prevent the Internet from initiating a connection with those instances. ”

C. Internet Gateway {IGW) – Correct! – it’s will add a public internet access
D.
Virtual Private Gateway (VGW) – Wrong! it’s just a software layer that connect you with on-premises VPN and the network must be initialize by the customer side.!
“A virtual private gateway is the VPN concentrator on the Amazon side of the VPN connection. ”

I would go for C and B as well.
NAT Gateway is Not correct. NAT will need to use IGW to connect to outside. It can not do anything by itself. Unlike IGW and VGW – they would directly take you outside.
C & D
