A VPC public subnet is one that:
A.
Has at least one route in its associated routing table that uses an Internet Gateway (IGW).
B.
Includes a route in its associated routing table via a Network Address Translation (NAT) instance.
C.
Has a Network Access Control List (NACL) permitting outbound traffic to 0.0.0.0/0.
D.
Has the Public Subnet option selected in its configuration.
This one is bad, correct option is A

If a subnet’s traffic is routed to an Internet gateway, the subnet is known as a public subnet.
the correct answer should be A.

Does admin purposefully put wrong answers ?
They just copy paste from some place.
D is the right answer
No it’s not, I just took an entire semester long course on this, and we went over this time and time again. What makes a subnet public is having a route to the IGW.
A
There is no public subnet in the configuration. The fact it is public is due to the attachment to an internet GW- Thus making it public.
A
A public VPC Subnet is the one:
1) That has 0.0.0.0/0 in its associated routing table pointing at the IGW of the VPC
2) The VPC has an IGW created and attached
So I would go with A
A is entirely the right answer. D is a nonsense answer, there is no “public configuration” when setting up a subnet. D is wrong.
from Amazons own documentation – http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_Subnets.html
If a subnet’s traffic is routed to an Internet gateway, the subnet is known as a public subnet.
I think A. C is mean when you create a VPC default by VPC Wizard
These wrong answers seem almost deliberate. Anyone who has ever created a subnet in AWS knows there is no such option as D. lol
A for sure
