Topic 1 Question 171
3 つ選択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?
Create four virtual private gateways. Attach the virtual private gateways to the four VPCs.
Create a Direct Connect gateway. Associate the four virtual private gateways with the Direct Connect gateway.
Create four transit VIFs on each Direct Connect connection. Associate the transit VIFs with the Direct Connect gateway.
Create four transit VIFs on each Direct Connect connection. Associate the transit VIFs with the four virtual private gateways.
Create four private VIFs on each Direct Connect connection to the Direct Connect gateway.
Create an association between the Direct Connect gateway and the transit gateways.

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

As there is no answer that allows us to configure specific route tables in the TGW to make the DataCenters really only have access to 4 of the 30 VPCs. The most logical solution is ABE, as the other options would allow access to more VPCs than intended.
