A, C, D: Require additional setup, management, or ML knowledge.

The correct answer is A because the application is a global Voice over IP workload that needs low latency , high availability , and automated failover across AWS Regions . AWS Global Accelerator is specifically designed to improve the availability and performance of global applications by routing user traffic over the AWS global network to the optimal healthy endpoint. It uses static Anycast IP addresses , which means users connect through fixed IP addresses that do not depend on client-side DNS or IP address caching behavior.

This is especially valuable for latency-sensitive applications such as Voice over IP, where rapid routing decisions and fast failover are critical. Global Accelerator continuously monitors endpoint health and can automatically direct traffic to healthy endpoints in another AWS Region if a failure occurs. This supports the requirement for cross-Region failover with minimal disruption.

Option B is incorrect because Route 53 geolocation routing directs traffic based on user location, but DNS-based routing can be affected by client-side caching and does not provide the same performance acceleration or fast failover behavior as Global Accelerator. Option C is incorrect because Amazon CloudFront is primarily a content delivery network for HTTP and similar content distribution scenarios, not the preferred service for real-time Voice over IP traffic. Option D is incorrect because an Application Load Balancer does not by itself provide global routing or multi-Region failover.

AWS best practices for global, latency-sensitive applications recommend AWS Global Accelerator when the goal is to improve performance, use the AWS backbone network, and provide health-based failover without depending on DNS cache expiration. Therefore, AWS Global Accelerator with health checks is the best solution.

S3 Object Lock: Enables Write Once Read Many (WORM) protection for data, preventing objects from being deleted or modified for a set retention period.

S3 Versioning: Helps maintain object versions and ensures a recovery path for accidental overwrites.

CloudFront Distribution: Ensures secure and efficient public access by serving content through an edge-optimized delivery network while protecting S3 data with OAC.

Bucket Policy for OAC: Restricts public access to only the CloudFront origin, ensuring maximum security.
