AWS Certified Solutions Architect Associate SAA-C03 Practice Question
A company has an online transactional processing system that often experiences heavy read traffic, which causes increased latency. The database must be contained within a single region due to data sovereignty requirements. Which database solution should be recommended to reduce read latency and maintain data sovereignty?
Configure a Multi-AZ deployment for synchronous replication
Increase the database instance size for better performance
Implement read replicas within the same AWS Region
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.
