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? A. Create a Client VPN endpoint in each AWS account. Configure required routing that allows access to internal applications. B. Create a Client VPN endpoint in the main AWS account. Configure required routing that allows access to internal applications. C. Create a Client VPN endpoint in the main AWS account. Provision a transit gateway that is connected to each AWS account. Configure required routing that allows access to internal applications. D. Create a Client VPN endpoint in the main AWS account. Establish connectivity between the Client VPN endpoint and the AWS Site-to-Site VPN.
