SAP-C02 Question #482: Real Exam Question with Answer & Explanation

Question

A solutions architect is designing an AWS account structure for a company that consists of multiple teams. All the teams will work in the same AWS Region. The company needs a VPC that is connected to the on-premises network. The company expects less than 50 Mbps of total traffic to and from the on-premises network. Which combination of steps will meet these requirements MOST cost-effectively? (Choose two.)

Options

• ACreate an AWS CloudFormation template that provisions a VPC and the required subnets.
• BCreate an AWS CloudFormation template that provisions a VPC and the required subnets.
• CUse AWS Transit Gateway along with an AWS Site-to-Site VPN for connectivity to the on-
• DUse AWS Site-to-Site VPN for connectivity to the on-premises network.
• EUse AWS Direct Connect for connectivity to the on-premises network.

Explanation

A solutions architect needs to design a cost-effective AWS account structure including a VPC connected to an on-premises network, anticipating less than 50 Mbps of total traffic.

Common mistakes.

• A. AWS Client VPN is designed to securely connect individual client devices to AWS VPCs, not to establish a site-to-site connection between an entire on-premises network and a VPC.
• C. While AWS Site-to-Site VPN is correct for connectivity, using AWS Transit Gateway in conjunction is generally overkill and less cost-effective for connecting a single VPC to an on-premises network, as Transit Gateway is designed for managing connections between many VPCs and on-premises networks.
• E. AWS Direct Connect provides dedicated, high-bandwidth network connections, which would be significantly more expensive and generally unnecessary for a requirement of less than 50 Mbps of total traffic and a focus on cost-effectiveness.
