Users will access all the application instances from the Internet, as well as from an onpremises network. The on-premises network is connected to your VPC over an AWS Direct Connect link. How would you design routing to meet the above requirements?
A. Configure a single routing table with a default route via the Internet gateway. Propagate a default route via BGP on the AWS Direct Connect customer router. Associate the routing table with all VPC subnets.
B. Configure a single routing table with a default route via the Internet gateway. Propagate specific routes for the on-premises networks via BGP on the AWS Direct Connect customer router. Associate the routing table with all VPC subnets.
C. Configure two routing tables: one that has a default route via the Internet gateway, and another that has a default route via the VPN gateway. Associate both routing tables with each VPC subnet.
D. Configure a single routing table with two default routes: one to the Internet via an Internet gateway, the other to the on-premises network via the VPN gateway. Use this routing table across all subnets in your VPC.
