Question
A company has a total of 30 VPCs. Three AWS Regions each contain 10 VPCs. The company has attached the VPCs in each Region to a transit gateway in that Region. The company also has set up inter-Region peering connections between the transit gateways. The company wants to use AWS Direct Connect to provide access from its on-premises location for only four VPCs across the three Regions. The company has provisioned four Direct Connect connections at two Direct Connect locations. Which combination of steps will meet these requirements MOST cost-effectively? (Choose three.)

- ACreate four virtual private gateways. Attach the virtual private gateways to the four VPCs.
- BCreate a Direct Connect gateway. Associate the four virtual private gateways with the Direct
- CCreate four transit VIFs on each Direct Connect connection. Associate the transit VIFs with the

Explanation
TGW for inter VPC peering within AWS. From on-prem access to only 4 VPCs is required. Hence DXGW and VGW via private VIF. Peering TGW with DXGW would be possible for on-prem connectivity but is more costly. https://docs.aws.amazon.com/whitepapers/latest/hybrid-connectivity/aws-dx-dxgw-with-vgw-multi- regions-and-aws-public-peering.html
