AWS Certified Advanced Networking – Specialty (ANS-C01) — Question 167
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.)
Answer options
- A. Create four virtual private gateways. Attach the virtual private gateways to the four VPCs.
- B. Create a Direct Connect gateway. Associate the four virtual private gateways with the Direct Connect gateway.
- C. Create four transit VIFs on each Direct Connect connection. Associate the transit VIFs with the Direct Connect gateway.
- D. Create four transit VIFs on each Direct Connect connection. Associate the transit VIFs with the four virtual private gateways.
- E. Create four private VIFs on each Direct Connect connection to the Direct Connect gateway.
- F. Create an association between the Direct Connect gateway and the transit gateways.
Correct answer: A, B, E
Explanation
The correct steps include creating four virtual private gateways for the specific VPCs, setting up a Direct Connect gateway to manage the connections, and provisioning private VIFs to connect to the Direct Connect gateway, which is the most cost-effective approach. The other options either involve unnecessary transit VIFs or do not properly link the gateways and VPCs as required.
