Virtual Private Cloud Quiz
A company has an on-premises infrastructure which they want to extend to the AWS Cloud. There is a need to ensure that communication across both environments is possible over the Internet. What would you create in this case to fulfill this requirement?
A. Create a VPC peering connection between the on-premises and the AWS Environment.
B. Create an AWS Direct connection between the on-premises and the AWS Environment.
C. Create a VPN connection between the on-premises and the AWS Environment.
D. Create a Virtual private gateway connection between the on-premises and the AWS Environment.
C. Create a VPN connection between the on-premises and the AWS Environment.
AWS Documentation mentions the following:
One can create a Virtual private connection to establish communication across both environments over the Internet.

https://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_VPN.htmlOption A is invalid because A VPC peering connection is a networking connection between two VPCs that enables you to route traffic between them using private IPv4 addresses or IPv6 addresses. It is not used for connection between on-premise environment and AWS.Option D is invalid because A virtual private gateway is the Amazon VPC side of a VPN connection. For the communication to take place between the on-premise servers to AWS EC2 instances with in the VPC, we need to set up the customer gateway at the on-premise location.Note:The question says that “There is a need to ensure that communication across both environments is possibleover the Internet.” AWS Direct Connect does not involve the Internet.A VPC VPN Connection utilizes IPSec to establish encrypted network connectivity between your intranet and Amazon VPC over the Internet. VPN Connections can be configured in minutes and are a good solution if you have an immediate need, have low to modest bandwidth requirements, and can tolerate the inherent variability in Internet-based connectivity.AWS Direct Connect does not involve the Internet;instead, it uses dedicated, private network connections between your intranet and Amazon VPC.
