A healthcare provider is migrating its patient record system to AWS. To comply with national regulations, all patient data must remain physically within a specific country's borders. Additionally, the application must be designed to remain fully operational even if an entire data center facility experiences a physical power outage. Which of the following AWS Global Infrastructure configurations best meets both the data residency and high availability requirements?
- ADeploying the application across multiple Edge Locations within the target country to distribute the database workload and cache patient files.
- Deploying the application in a single AWS Region located in the target country, distributing the workload across multiple Availability Zones.Cevap
- CDeploying the application across multiple AWS Regions to ensure geographic redundancy and using AWS Artifact to manage cross-region data replication.
- DDeploying the application in a single Availability Zone and using AWS Local Zones in adjacent countries to replicate the data.
Cevap
Deploying the application in a single AWS Region located in the target country, distributing the workload across multiple Availability Zones.
Deploying the application in a single AWS Region located within the target country satisfies the data residency requirement because AWS does not replicate data outside of a selected Region unless configured by the customer. Distributing the application across multiple Availability Zones within that Region satisfies the high availability requirement, as each Availability Zone consists of one or more physical data centers designed to be isolated from failures in other zones.

AWS Regions provide data residency boundaries, while Availability Zones within a region provide fault isolation and high availability.
