Question

A company has many VPCs in the us-east-1 Region. The company uses a transit gateway to connect the VPCs to one another. The company recently acquired a smaller company that has a single VPC named VPC-Z. A network engineer needs to onboard VPC-Z to the existing transit gateway. The network engineer notices an IP address overlap between VPC-Z and VPC-A. The network engineer must establish outbound connectivity from VPC-Z to all the company's other VPCs, including VPC-A. Which combination of solutions will meet this requirement? (Choose two.)

Accepted Answer

Correct answer: A, C. The correct answer is A, C. Option A: Create a new non-overlapping CIDR block in VPC-Z. Create two subnets that use the new CIDR block. Option C: Create a private NAT gateway in VPC-Z in a non-overlapping subnet. Advertise only the non-overlapping VPC-Z CIDR block to the transit gateway route table. AWS Transit Gateway centrally connects many VPCs and on-premises networks at scale. A NAT gateway lets private subnet resources reach the internet for outbound traffic only.
