Exam AWS-SysOps topic 1 question 790 discussion

D. Add an entry to the route table for the subnet that points to an internet gateway E. Create an internet gateway and attach it to a VPC

D & E are correct. A is wrong....No Need for NAT GW unless you're in a private AZ/subnet. B is wrong....No need for this either. In both these cases check your own AWS VPC setup, there's No NAT Gateway and No elestic IP attached to your IGW. C is therefore wrong for the same reason. | If you're creating custom VPC, the firt thing you need is an IGW....D is correct. You IGW will appear as Detached in your VPC dashboard until you associate with VPC, and your VPC will have no internet access until you associate an IGW.

DE, are the answer

D | E are the answers The problem does not mention that EC2 would be in a private subnet, so NAT is not required. What is needed is to attach a IGW in the VPC (E) and then create a route in the RT, so the subnet where the EC2 is, gain access to internet (D)

A E is correct A provides outbound traffic E provides inbound traffic D is not correct try to do what is stated in there and you will see doesn't really make sense.

I'll go with D,E

D. Add an entry to the route table for the subnet that points to an internet gateway E. Create an internet gateway and attach it to a VPC

D and E, C does not apply since you don't assign an IP to an IGW

C and E because we don't know if the instance is in private or public subnet.
