AWS Certified Solutions Architect – Professional — Question 747

A software development company has multiple engineers who are working remotely. The company is running Active Directory Domain Services (AD DS) on an Amazon EC2 instance. The company's security policy states that all internal, nonpublic services that are deployed in a VPC must be accessible through a VPN. Multi-factor authentication (MFA) must be used for access to a VPN.

What should a solutions architect do to meet these requirements?

Answer options

• A. Create an AWS Site-to-Site VPN connection. Configure integration between a VPN and AD DS. Use an Amazon Workspaces client with MFA support enabled to establish a VPN connection.
• B. Create an AWS Client VPN endpoint. Create an AD Connector directory for integration with AD DS. Enable MFA for AD Connector. Use AWS Client VPN to establish a VPN connection.
• C. Create multiple AWS Site-to-Site VPN connections by using AWS VPN CloudHub. Configure integration between AWS VPN CloudHub and AD DS. Use AWS Copilot to establish a VPN connection.
• D. Create an Amazon WorkLink endpoint. Configure integration between Amazon WorkLink and AD DS. Enable MFA in Amazon WorkLink. Use AWS Client VPN to establish a VPN connection.

Correct answer: B

Explanation

AWS Client VPN is the appropriate service for allowing individual remote users to securely connect to AWS VPC resources. By pairing it with an AD Connector integrated with the self-managed AD DS on EC2, administrators can easily enable MFA to satisfy the security policy. Site-to-Site VPN is incorrect as it is designed for connecting entire remote networks rather than individual remote endpoints, and Amazon WorkLink is not a VPN service.
