A financial services company that has on-premises infrastructure has acquired a startup company that has an API that is deployed in the AWS Cloud. As part of the acquisition, the financial services company has deployed an AWS Direct Connect private VIF to establish IP connectivity between the on-premises data center and the AWS environment.
Initial IP connectivity testing and bidirectional DNS resolution testing are successful. However, when business users attempt to connect to the API. a network administrator discovers IP subnet overlap between the financial services company's existing network and the startup company's AWS deployment.
A network architect receives the following diagram that summarizes the situation:
What is the MOST operationally efficient solution to enable the connectivity?
A. Provision additional subnets with a non-overlapping IP range in the VPC. Deploy NAT gateways. Configure the virtual private gateway's next hop to be the NAT gateway. Advertise the new subnet IP address ranges through Direct Connect. Configure the on-premises hosts to target the API endpoint through the API servers.
B. Provision additional subnets with a non-overlapping IP range in the VPC. Deploy a Network Load Balancer (NLB) across the subnets. Configure the API endpoints in a target group that is associated with the NLB. Advertise the new subnet IP address ranges through Direct Connect. Configure the on-premises hosts to target the API endpoint through the NLB.
C. Provision additional subnets with a non-overlapping IP range in a new VPC. Deploy a Network Load Balancer (NLB) across the subnets. Configure the API endpoints as targets by IP address in a target group that is associated with the NLB. Peer the two VPCs together, and relocate the virtual private gateway into the new VPC. Advertise the new subnet IP address ranges through Direct Connect. Configure the on-premises hosts to target the API endpoint through the NLB.
D. Provision additional subnets with a non-overlapping IP range in the VPC. Deploy a Network Load Balancer (NLB) across the existing subnets. Configure the API endpoints in a target group that is associated with the NLB. Configure a VPC endpoint service that targets the newly created NLB, and deploy VPC endpoints into the new subnet. Advertise the new subnet IP address ranges through Direct Connect. Configure the on-premises hosts to target the API endpoint through the VPC endpoints.
