A SaaS provider hosts its solution on Amazon EC2 instances within a VPC in AWS. All customers also operate their environments in AWS. During a design meeting, it was discovered that customers have overlapping IP addresses with the provider's AWS deployment. Customers have refused to share their internal IP addresses and do not want to connect to the SaaS service over the internet.
Which two steps should be combined to create a solution that meets these requirements?
A
Deploy the SaaS service endpoint behind a Network Load Balancer.
B
Configure an endpoint service, and grant the customers permission to create a connection to the endpoint service.
C
Deploy the SaaS service endpoint behind an Application Load Balancer.
D
Configure a VPC peering connection to the customer VPCs. Route traffic through NAT gateways.
E
Deploy an AWS Transit Gateway, and connect the SaaS VPC to it. Share the transit gateway with the customers. Configure routing on the transit gateway.
