A Company Hosts Its Core Network Services, Including Directory Services

A company hosts its core network services, including directory services and DNS, in its on-premises data center. The data center is connected to the AWS Cloud using AWS Direct Connect (DX) . Additional AWS accounts are planned that will require quick, cost-effective, and consistent access to these network services. What should a solutions architect implement to meet these requirements with the LEAST amount of operational overhead?

A) Create a DX connection in each new account. Route the network traffic to the on-premises servers.
B) Configure VPC endpoints in the DX VPC for all required services. Route the network traffic to the on-premises servers.
C) Create a VPN connection between each new account and the DX VPC. Route the network traffic to the on-premises servers.
D) Configure AWS Transit Gateway between the accounts. Assign DX to the transit gateway and route network traffic to the on-premises servers.
