• Chose A1

  The correct answer is A. Explanation: In the current configuration, you have VPC peering between Sales and Finance, and Marketing and Finance, but this does not allow for full connectivity between all three VPCs (Sales ↔ Marketing). To achieve connectivity between all three VPCs, you need to configure VPC peering in a full mesh, meaning you need to establish VPC peering connections between all three VPCs: Sales ↔ Finance, Marketing ↔ Finance, and Sales ↔ Marketing. This ensures that traffic can flow between all VPCs.

• Chose A1

  Create a Full Messh Peering to achieve the connectivity between all the VPC, as peering is not transitive.

• Chose A1

  Full Mesh VPC Peering: VPC peering in a full mesh means establishing direct peering connections between all pairs of VPCs (Sales, Marketing, and Finance). In a full mesh topology, all VPCs are interconnected, allowing traffic to flow seamlessly between any pair of VPCs. Routing Considerations: Ensure that the routing tables in each VPC are appropriately configured to handle traffic between all the VPCs in the full mesh. VPC peering generally allows transitive routing, meaning if VPC A is peered with VPC B and VPC B is peered with VPC C, then VPC A can communicate with VPC C.
