AWS Certified Solutions Architect Associate SAA-C03 Practice Question

The best solution to reduce read latency while maintaining data sovereignty is to implement read replicas within the same region. Read replicas allow you to have a read-only copy of your data, which can be used to handle read traffic, thereby distributing the load and reducing the overall latency on the primary database. Implementing them within the same region adheres to data sovereignty requirements. Multi-AZ deployment is for high availability rather than read scaling, cross-region read replicas violate data sovereignty, and caching does not address the database read operation latency as effectively as read replicas.
