Answer: Create a Direct Connect gateway. Create a transit gateway in each Region. Attach the transit gateways to the Direct Connect gateway. Create a transit VIF on each of the Direct Connect connections. Attach the transit VIFs to the Direct Connect gateway. Peer the transit gateways. Attach the transit gateways in each Region to the VPCs in the same Region.
The correct solution must ensure connectivity between all VPCs across the two AWS Regions and the on-premises network, with failover capabilities and maintaining the required geographical separation. Option C is the correct choice because it involves creating a Direct Connect gateway and transit gateways in each Region, which are then attached to the Direct Connect gateway. Transit VIFs are created on each Direct Connect connection and attached to the Direct Connect gateway. Peering the transit gateways ensures connectivity between the two Regions. Attaching the transit gateways to the VPCs in their respective Regions ensures that all services in both Regions are accessible, even in case of network issues. This setup provides the necessary redundancy and failover capabilities, meeting the company's requirements.

A European car manufacturer is migrating its customer-facing services and analytics platform from two on-premises data centers, located 50 miles (80.4 km) apart, to the AWS Cloud. The company must maintain the same separation between its two cloud locations and ensure failover capabilities between them. The infrastructure team has created multiple accounts to separate workloads and responsibilities, provisioning resources in the eu-west-3 and eu-central-1 Regions. The company has engaged an AWS Direct Connect Partner in each Region, requesting two resilient 1 Gbps fiber connections from each provider.
The network engineer must establish connectivity between all VPCs across the accounts and between the on-premises network and the AWS Cloud. The solution must ensure access to all services in both Regions in the event of network issues.
What solution meets these requirements?
A
Create a Direct Connect gateway. Create a private VIF on each of the Direct Connect connections. Attach the private VIFs to the Direct Connect gateway. Use equal-cost multi-path (ECMP) routing to aggregate the four connections across the two Regions. Attach the Direct Connect gateway directly to each VPC's virtual private gateway.
B
Create a Direct Connect gateway. Create a transit gateway. Attach the transit gateway to the Direct Connect gateway. Create a transit VIF on each of the Direct Connect connections. Attach the transit VIFs to the Direct Connect gateway. Use a link aggregation group (LAG) to aggregate the four connections across the two Regions. Attach the transit gateway directly to each VPC.
C
Create a Direct Connect gateway. Create a transit gateway in each Region. Attach the transit gateways to the Direct Connect gateway. Create a transit VIF on each of the Direct Connect connections. Attach the transit VIFs to the Direct Connect gateway. Peer the transit gateways. Attach the transit gateways in each Region to the VPCs in the same Region.
D
Create a Direct Connect gateway. Create a private VIF on each of the Direct Connect connections. Attach the private VIFs to the Direct Connect gateway. Use a link aggregation group (LAG) to aggregate the four connections across the two Regions. Create a transit gateway. Attach the transit gateway to the Direct Connect gateway. Attach the transit gateway directly to each VPC.
