Amazon CLF-C02: What Are the Key Components of AWS Site-to-Site VPN Connection?

Discover the essential components of an AWS Site-to-Site VPN connection, including the Virtual Private Gateway and Customer Gateway, to enhance your understanding for the AWS Certified Cloud Practitioner CLF-C02 exam.

Question

Which of the following are components of an AWS Site-to-Site VPN connection? (Select TWO.)

A. AWS Storage Gateway
B. Virtual private gateway
C. NAT gateway
D. Customer gateway
E. Internet Gateway

Answer

In the context of the AWS Site-to-Site VPN connection, the correct components are:

B. Virtual private gateway
D. Customer gateway

Explanation

The correct answers are B and D because a virtual private gateway and a customer gateway are components of an AWS Site-to-Site VPN connection. A virtual private gateway is the AWS side of the VPN connection that connects to the customer’s VPC. A customer gateway is the customer side of the VPN connection that resides on the customer’s network. The other options are incorrect because they are not components of an AWS Site-to-Site VPN connection. AWS Storage Gateway is a service that connects on-premises software applications with cloud-based storage. NAT gateway is a service that allows instances in a private subnet to connect to the Internet or other AWS services, but prevents the Internet from initiating a connection with those instances. Internet Gateway is a service that allows communication between instances in a VPC and the Internet.

Virtual Private Gateway (VGW)

The Virtual Private Gateway is a crucial component that acts as the VPN concentrator on the AWS side of the connection. It enables secure communication between your Amazon Virtual Private Cloud (VPC) and your on-premises network. When establishing a Site-to-Site VPN, you create a VGW and attach it to your VPC, allowing traffic to flow securely over the public internet using IPsec encryption.

Customer Gateway (CGW)

The Customer Gateway represents your on-premises network device (such as a router or firewall) that connects to the AWS environment. This resource is configured in AWS to point to your physical or virtual gateway at your location. When creating a CGW in AWS, you provide details about your on-premises device, including its public IP address, which is essential for establishing the VPN connection.

Why Other Options Are Incorrect

A. AWS Storage Gateway: This service is designed for integrating on-premises environments with cloud storage but is not a component of a Site-to-Site VPN connection.
C. NAT Gateway: A NAT Gateway is used for enabling instances in a private subnet to access the internet but does not play a role in establishing a VPN connection.
E. Internet Gateway: While an Internet Gateway allows communication between instances in your VPC and the internet, it is not a component of the Site-to-Site VPN itself.

Understanding these components is vital for successfully configuring an AWS Site-to-Site VPN and is essential knowledge for passing the AWS Certified Cloud Practitioner CLF-C02 exam.
