AWS Certified Solutions Architect – Associate (SAA-C02) — Question 234

A company needs a secure connection between its on-premises environment and AWS. This connection does not need high bandwidth and will handle a small amount of traffic. The connection should be set up quickly.
What is the MOST cost-effective method to establish this type of connection?

Answer options

• A. Implement a client VPN.
• B. Implement AWS Direct Connect.
• C. Implement a bastion host on Amazon EC2.
• D. Implement an AWS Site-to-Site VPN connection.

Correct answer: D

Explanation

The AWS Site-to-Site VPN connection is the most cost-effective option for securely connecting on-premises environments to AWS with low bandwidth requirements and minimal traffic. Other options like AWS Direct Connect are typically more expensive and not necessary for small traffic needs, while a client VPN and bastion host do not provide the same level of direct connectivity as a Site-to-Site VPN.
