A. B. C. D.Answer - B.
This sort of scenario is given in the AWS Documentation.
Configuration Details.
The configuration in this example consists of two dynamically routed connections, one using AWS Direct Connect and the other using a VPN connection from two different customer devices.
AWS provides example router configurations to assist in establishing both AWS Direct Connect and VPN connections with BGP for dynamic routing.
By default, AWS will always prefer to send traffic over an AWS Direct Connect connection, so no additional configuration is required to define primary and backup connections.
In this example, both Customer Gateway 1 and Customer Device 2 advertise a summary route of 10.0.0.0/16
AWS will send all traffic to Customer Device 2 as long as this network path is available.
By default, all other options become invalid.
