A company wants to connect multiple AWS VPCs to their on-premises data center using a hub-and-spoke topology with AWS Transit Gateway. Which of the following components or configurations are required to establish this network connectivity? (Select TWO).
- Transit Gateway attachments created for each VPC to connect them to the Transit Gateway.Answer
- A Transit Gateway attachment to a VPN connection or Direct Connect gateway to establish the hybrid link to the on-premises network.Answer
- CA full mesh of VPC peering connections between all VPCs to enable transit routing between the VPCs and the Transit Gateway.
- DRoute 53 Private Hosted Zone associations across all VPCs to handle IP-level routing between the VPCs and the Transit Gateway.
Answer
Transit Gateway attachments created for each VPC to connect them to the Transit Gateway, and a Transit Gateway attachment to a VPN connection or Direct Connect gateway to establish the hybrid link to the on-premises network.
Establishing a hub-and-spoke hybrid network with Transit Gateway requires attaching the spoke VPCs directly to the Transit Gateway, and establishing a hybrid connectivity attachment (such as VPN or Direct Connect) to bridge the Transit Gateway to the on-premises data center.
Step-by-Step Solution
Key Concept
AWS Transit Gateway acts as a cloud router to simplify hybrid and multi-account hub-and-spoke networking by using attachments to connect VPCs and hybrid paths.
