A user has created a VPC with CIDR 20.0.0.0/16 using VPC Wizard. The user has created a
public CIDR
(20.0.0.0/24. and a VPN only subnet CIDR (20.0.1.0/24. along with the hardware VPN access to
connect to the user’s data centre. Which of the below mentioned components is not present when
the VPC is setup with the wizard?
A.
Main route table attached with a VPN only subnet
B.
A NAT instance configured to allow the VPN subnet instances to connect with the internet
C.
Custom route table attached with a public subnet
D.
An internet gateway for a public subnet
Explanation:
The user can create subnets as per the requirement within a VPC. If the user wants to connect
VPC from his own data centre, he can setup a public and VPN only subnet which uses hardware
VPN access to connect with his data centre. When the user has configured this setup with Wizard,
it will update the main route table used with the VPN-only subnet, create a custom route table and
associate it with the public subnet. It also creates an internet gateway for the public subnet. The
wizard does not create a NAT instance by default. The user can create it manually and attach it
with a VPN only subnet.

The answer to this question may be helpful in questions #167 and #209 NAT instances aren’t automatically created with VPCs but were with EC2 classic. NAT gateways are used with today’s VPCs.
