1. $0.005 per GB

2. $0.015 per GB

3. $0.020 per GB

4. $0.030 per GB

The correct answer is: $0.020 per GB

The charge for data transfer out over a VPN using AWS Direct Connect public Virtual Interface (VIF) is indeed $0.020 per GB. This rate applies specifically to the data that is transferred from AWS services to the internet through the public VIF. AWS pricing for data transfer can vary based on the specific service being utilized, the direction of transfer (in or out), and whether it is using a VPN, Direct Connect, or other network services. In this case, the pricing structure is established to reflect the cost of providing high availability and performance for data transported over a dedicated connection versus a standard internet connection. Understanding that the Direct Connect service provides a dedicated network connection helps clarify why there is a specific pricing tier associated with data transfers, especially in high-demand use cases like VPN connections. Typically, AWS has separate prices for private and public VIFs, and it's critical to identify the correct interface when considering costs associated with data transfer out. Overall, the $0.020 per GB charge for transferring data out over a Direct Connect public VIF aligns with AWS's pricing guidelines and reflects the specialized nature of this connectivity option.
