Your company has an AWS Direct Connect connection from a VPC to an on-premises location. Which of the following can be used as a backup if the Direct Connect connection fails for any reason? Choose 2 answers from the options given below.

Answer options:

A.There is no need to configure this as AWS will fall back to a secondary Direct Connect connection as per their SLA.B.Set up a secondary Direct Connect connection.
C.Set up a VPN connection.
D.Set up a peering connection.

Answer – B and C
The AWS Documentation mentions the following.
If you have established a second AWS Direct Connect connection, traffic will fail over to the second link automatically. We recommend enabling Bidirectional Forwarding Detection (BFD) when configuring your connections to ensure fast detection and failover. If you have configured a backup IPsec VPN connection instead, all VPC traffic will fail over to the VPN connection automatically. Traffic to/from public resources such as Amazon S3 will be routed over the Internet.
Option A is invalid because AWS will not fall back to a secondary connection. You have to ensure high availability.
Option D is invalid because this is only used for connecting 2 VPCs together.
