A company is using AWS Cloud WAN with one edge location in the us-east-1 Region and one edge location in the us-west-1 Region. A shared services segment exists at both edge locations. Each shared services segment has a VPC attachment to each inspection VPC in each Region. The inspection VPCs inspect traffic from a WAN by using AWS Network Firewall.

The company creates a new segment for a new business unit (BU) in the us-east-1 edge location. The new BU has three VPCs that are attached to the new BU segment. To comply with regulations, the BU VPCs must not communicate with each other. All internet-bound traffic must be inspected in the inspection VPC.

The company updates VPC route tables so any traffic that is bound for internet goes to the AWS Cloud WAN core network.

The company plans to add more VPCs for the new BU in the future. All future VPCs must comply with regulations.

Which solution will meet these requirements in the MOST operationally efficient way? (Choose two.)
