Imagine You Are Using AWS Direct Connect with Just One

Imagine you are using AWS Direct Connect with just one connection from your router to the AWS Direct Connect router. If your connection becomes unavailable, the communication with AWS cloud is lost. What is the best method to prevent this from happening?

A) AWS Direct Connect neither provides BGP nor provides the failover.
B) AWS Direct Connect recommends to have the same configuration set up in a multi AZ zone to prevent such loss in connections.
C) AWS Direct Connect recommends that you request and configure two dedicated connections to AWS either using BGP Multipath (Active/Active) connection or the failover (Active/Passive) connection.
D) AWS Direct connect does not have a provision to prevent the situation but when you design the system, it is recommended to request a back-up instance to which the traffic can be re-routed.
