A company operates five VPCs in the us-east-1 Region, hosting an internal web application in one of its VPCs, VPC-A. The company needs to connect VPC-A to an external partner's AWS environment in the same Region, where the partner hosts a new version of the web application in VPC-B. However, both VPC-A and VPC-B use overlapping IP address spaces. The company's EC2 instances in VPC-A must connect to the web application in VPC-B without disrupting the existing environments of either the company or the partner.

Which two actions should the network engineer take to meet these requirements?

A.
Create a VPC peering connection between VPC-A and VPC-B.

B.
Ensure the partner configures a VPC endpoint service in VPC-B using a Network Load Balancer.

C.
Deploy a VPC endpoint in VPC-A that connects to the partner's shared VPC endpoint service.

D.
Add a new routable VPC CIDR block as a secondary CIDR to both VPC-A and VPC-B, and deploy a public NAT gateway in VPC-A.
