Exam question from Amazon's AWS Certified Advanced Networking - Specialty ANS-C01
Question #: 246
Topic #: 1
[All AWS Certified Advanced Networking - Specialty ANS-C01 Questions]

A company has five VPCs in the us-east-1 Region. The company hosts an internal web application in us-east-1. One of the company's VPCs. named VPC-A, needs to connect to an external partner's AWS environment. The partner’s environment is in the same AWS Region where the partner hosts a new version of the company's web application. The partner hosts its version of the application in a VPC named VPC-B.

The company has Amazon EC2 instances in VPC-A that need to connect to the web application in VPC-B A network engineer notices that the partner's VPC-B and the company's VPC-A use the same IP space. The network engineer needs a solution to allow the EC2 instances to connect to the web application. The solution must not negatively affect the exiting environment of the company or the partner.

Which combination of steps should the network engineer take meet these requirements? (Choose two.)

  • A. Establish a VPC peering connection between VPC-A to VPC-B.
  • B. Ensure the partner creates a VPC endpoint service that uses a Network Load Balancer in VPC-B.
  • C. Deploy a VPC endpoint in VPC-A that uses a VPC endpoint service that is shared by the partner.
  • D. Deploy a new routable VPC CIDR block as a secondary CIDR block to both VPC-A and VPC-B. Deploy a public NAT gateway in VPC-A.
  • E. Establish an AWS Site-to-Site VPN connection between VPC-A and VPC-B.

AWS PrivateLink (which uses VPC endpoint services) is specifically designed to connect services across VPCs without requiring overlapping CIDR ranges to be routable between them. This solves the IP overlap problem without requiring IP address changes. The partner would create a VPC endpoint service backed by a Network Load Balancer that fronts their web application in VPC-B. The company would then create a VPC endpoint in VPC-A that connects to the partner's endpoint service, allowing EC2 instances to access the application using a private DNS name that resolves to a private IP within VPC-A's address space.
