You are trying out an AWS VPN managed connection. You have created the VPN to your on-premises location. You earlier were also using an Internet gateway. You’ve added the VPN connection to your routing table and enabled propagation. Below is the Route table.
Based on the route table, which of the following is TRUE?

Answer options:

A.Traffic destined for 172.31.0.0/24 will go through the Virtual Private gateway.
B.Traffic destined for 172.31.0.0/24 will go through the Internet gateway.
C.Traffic destined for 172.31.0.0/24 will go through the local router.
D.This is not possible; you cannot have 2 routes with the same destination.

Answer – B
Such an example is given in the AWS Documentation.
Option A is incorrect because of the way traffic is routed based on priority.
Option C is incorrect because there is no route defined for such routing.
Option D is incorrect because you can have multiple routes with the same destination.
