Amazon CloudWatch Container Insightsis designed for monitoring containerized environments like EKS. It provides native support for collecting and visualizing metrics and logs in a centralized location through CloudWatch dashboards, offering the most operationally efficient solution.

Option A:Using the CloudWatch agent provides basic metrics but lacks the specific insights required for containerized applications.

Option B:Kinesis Data Streams and Firehose add unnecessary complexity for this use case.

Option C:CloudTrail is for auditing API activity and is not designed for application metrics and log aggregation.

Amazon CloudWatch Container Insights

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.

Amazon S3 Intelligent-Tiering is designed for data with unknown or changing access patterns. It automatically moves data between frequent and infrequent access tiers based on usage. This tier offers immediate access to all objects, regardless of which tier they are stored in, while optimizing storage costs. S3 Intelligent-Tiering also provides the same high durability, availability, and security as other S3 storage classes and supports access from external resources using standard S3 APIs. Lifecycle policies and Glacier classes are more suitable for archival when infrequent access is predictable, but retrieval from Glacier classes is not immediate and incurs extra charges and delays.

Reference Extract from AWS Documentation / Study Guide:

" S3 Intelligent-Tiering is designed to optimize costs by automatically moving data between two access tiers when access patterns change. Data is always available and immediately accessible, making it ideal for unknown or unpredictable access patterns. "
