You are designing the network infrastructure for an application server in Amazon VPC. Users will access all application instances from the Internet, as well as from an on-premises 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 a single routing table with two default routes: on 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 the VP
E . Configure two routing tables: on that has a default router via the Internet gateway, and other that has a default route via the VPN gateway. Associate both routing tables with each VPC subnet.
