Free AWS Certified Solutions Architect Associate SAA-C03 Practice Question

An international financial organization must ensure their highly transactional application's operations can withstand the outage of a data center without any service interruption. Furthermore, the application should incur minimal latency for users in Europe, North America, and Asia. Considering cost-effectiveness and operational complexity, what deployment approach adheres BEST to these requirements?

  • Implement a global database cluster with cross-region read replicas to ensure the application’s relational data remains available and experiences low latency accesses.

  • Deploy the application into a single AWS Region and distribute it across multiple Availability Zones, leveraging Amazon Route 53 health checks for failover.

  • Establish the application in multiple AWS Regions each located near Europe, North America, and Asia, with an Amazon Route 53 latency-based routing policy.

  • Utilize one AWS Region to host the primary instance and establish cross-region read replicas in regions closest to Europe, North America, and Asia.
