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 VPC.
D.
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.
B: is the right answer
A: propagating default will have route conflicts
