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.

A
The wizard does not create ‘Main route table attached with a VPN only subnet’ but it does create the other three items.

The Internet Gateway is the NAT instance in case anyone is unsure.

Sorry Ans B
After you’ve created the VPC, you can view information about the subnet, the Internet gateway, and the route tables. The VPC that you created has two route tables — a main route table that all VPCs have by default, and a custom route table that was created by the wizard. The custom route table is associated with your subnet, which means that the routes in that table determine how the traffic for the subnet flows. If you add a new subnet to your VPC, it uses the main route table by default.
