The correct answer is C, 'Configure the architecture across multiple AWS Regions.' This approach ensures geographic redundancy and enhances the overall resilience of the infrastructure by replicating the infrastructure and data across different geographical locations. In the event of a disaster or disruption in one Region, the workload can be quickly and seamlessly shifted to another Region to maintain business continuity. While option A provides multiple accounts which can be useful for organizational purposes, it does not inherently provide geographic redundancy. Option B, deploying across multiple Availability Zones within a single AWS Region, offers high availability but not the geographic separation needed for disaster recovery. Option D, distributing the infrastructure among numerous edge locations, is more related to content delivery networks rather than a disaster recovery solution.
