A company has introduced a new policy that allows employees to work remotely from their homes if they connect by using a VPN. The company is hosting internal applications with VPCs in multiple AWS accounts. Currently, the applications are accessible from the company's on-premises office network through an AWS Site-to-Site VPN connection. The VPC in the company's main AWS account has peering connections established with VPCs in other AWS accounts. A solutions architect must design a scalable AWS Client VPN solution for employees to use while they work from home. What is the MOST cost-effective solution that meets these requirements?
