A large enterprise has 50 VPCs spread across multiple AWS Regions. They need to establish network connectivity between all VPCs and their on-premises data center. The solution must minimize management overhead and support transitive routing.<br/><br/>Which TWO statements about the architecture are correct? (Select TWO.)

Answer options:

The company should use VPC Peering to connect all VPCs.

The company should use AWS Transit Gateway.

VPC Peering supports transitive routing.

VPC Peering does not support transitive routing.

AWS Direct Connect natively provides transitive routing between VPCs.

How to approach this question

Understand the limitations of VPC Peering and the benefits of Transit Gateway.

Full Answer

The company should use AWS Transit Gateway.<br/>VPC Peering does not support transitive routing.

AWS Transit Gateway connects VPCs and on-premises networks through a central hub. This simplifies your network and puts an end to complex peering relationships. VPC Peering does not support transitive routing, meaning a full mesh network would be required for 50 VPCs, which is a massive management overhead.

Common mistakes

Thinking VPC Peering is scalable for dozens of VPCs.
