What should a solutions architect do to mitigate any single point of failure in this architecture?
Add a set of VPNs between the Management and Production VPCs.
Add a second virtual private gateway and attach it to the Management VPC.
Add a second set of VPNs to the Management VPC from a second customer gateway device.
Add a second VPC peering connection between the Management VPC and the Production VPC.
Explanations:
Adding a set of VPNs between the Management and Production VPCs would not address the single point of failure in the existing VPN connection to the data center or the Direct Connect connections in the Production VPC. This would only add complexity without improving overall resilience.
Adding a second virtual private gateway to the Management VPC does not address the single point of failure in the existing connection to the data center and would not provide redundancy for the Management VPC’s connectivity.
Adding a second set of VPNs to the Management VPC from a second customer gateway device provides redundancy for the Management VPC’s connection to the data center. This ensures that if one VPN connection fails, the other can still maintain connectivity, thus mitigating a single point of failure.
Adding a second VPC peering connection between the Management VPC and the Production VPC would not address any single point of failure in the connectivity to the data center or the Direct Connect connections in the Production VPC. This option would only provide additional communication paths between the two VPCs, but not improve the overall architecture’s resilience.
