A user has created a VPC with CIDR 20.0.0.0/16 using the wizard. The user has created a public subnet CIDR
(20.0.0.0/24. and VPN only subnets CIDR (20.0.1.0/24. along with the VPN gateway (vgw-12345. to connect to
the user’s data center. Which of the below mentioned options is a valid entry for the main route table in this
scenario?

A.
Destination: 20.0.0.0/24 and Target: vgw-12345

B.
Destination: 20.0.0.0/16 and Target: ALL

C.
Destination: 20.0.1.0/16 and Target: vgw-12345

D.
Destination: 0.0.0.0/0 and Target: vgw-12345

Explanation:
The user can create subnets as per the requirement within a VPC. If the user wants to connect VPC from his
own data center, he can setup a public and VPN only subnet which uses hardware VPN access to connect with
his data center. When the user has configured this setup with Wizard, it will create a virtual private gateway to
route all traffic of the VPN subnet. Here are the valid entries for the main route table in this scenario:
Destination: 0.0.0.0/0 & Target: vgw-12345 (To route all internet traffic to the VPN gateway.
Destination: 20.0.0.0/16 & Target: local (To allow local routing in VPC.
