How can the organization setup in this scenario?

A.
The organization should plan the app server on the public subnet and database in the organization's data center and connect them with the VPN gateway.
B. The organization should plan the app server on the public subnet and use RDS with the private subnet for a secure data operation.
C. The organization should use the public subnet for the app server and use RDS with a storage gateway to access as well as sync the data securely from the local data center.
D. The organization should plan the app server on the public subnet and database in a private subnet so it will not be in the public cloud.

Correct Answer: A

Explanation:

Explanation: A Virtual Private Cloud (VPC) is a virtual network dedicated to the user’s AWS account. 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 create a virtual private gateway to route all the traffic of the VPN subnet. If the virtual private gateway is attached with VPC and the user deletes the VPC from the console it will first automatically detach the gateway and only then delete the
VPC.
