An Australian ecommerce company hosts all of its services in the AWS Cloud and wants to expand its customer base to the United States (US). The company is targeting the western US for the expansion.
The company’s existing AWS architecture consists of four AWS accounts with multiple VPCs deployed in the ap-southeast-2 Region. All VPCs are attached to a transit gateway in ap-southeast-2. There are dedicated VPCs for each application service. The company also has VPCs for centralized security features such as proxies, firewalls, and logging.
The company plans to duplicate the infrastructure from ap-southeast-2 to the us-west-1 Region. A network engineer must establish connectivity between the various applications in the two Regions. The solution must maximize bandwidth, minimize latency and minimize operational overhead.
Which solution will meet these requirements?
- A. Create VPN attachments between the two transit gateways. Configure the VPN attachments to use BGP routing between the two transit gateways.
- B. Peer the transit gateways in each Region. Configure routing between the two transit gateways for each Region's IP addresses.
- C. Create a VPN server in a VPC in each Region. Update the routing to point to the VPN servers for the IP addresses in alternate Regions.
- D. Attach the VPCs in us-west-1 to the transit gateway in ap-southeast-2.
