True or false: To connect a VPC, AWS uses an implicit router that customers must configure to allow communication between VPCs.

In the context of AWS VPCs, the statement is false because AWS handles the routing infrastructure automatically for VPCs through its built-in routing capabilities. When you create a VPC and its subnets, AWS creates a route table for that VPC, and it implicitly provides a router that facilitates communication within the VPC's resources.

For inter-VPC communication, AWS offers a service called VPC Peering, which allows two VPCs to communicate directly using private IP addresses. When VPC Peering is established, AWS automatically configures the necessary routes to enable seamless communication between the connected VPCs, ensuring that users do not need to configure any additional routing for this purpose.

The correct understanding here is that while AWS provides default routing features, any additional configurations or specific routing policies may need to be set up by users, particularly in specialized multi-VPC scenarios or when integrating with on-premises networks. However, for VPCs communicating through peering, the implicit routing setup is handled by AWS without requiring explicit customer configuration.
