CloudFront cache hit and regional egress metrics improve during repeated downloads might confirm another remediation, for instance when a company transfers the same static downloads repeatedly between remote users and one AWS Region. This question instead requires demonstrating that a cost model shows the simpler peering path meets both traffic and governance requirements. The alternative would not validate the selected network fix.

A measured cost-and-failover model supports the selected egress design might confirm another remediation, for instance when a multi-account organization pays for duplicated NAT gateways in every tiny development VPC.
