Amazon EFS is the correct answer because it provides aPOSIX-compliant, shared file systemthat multiple ECS tasks and instances can mount concurrently. AWS documents EFS as a managed NFS file system built for shared access and elastic growth, which fits the requirement for log and configuration sharing across Linux containers.Elastic throughputis the best cost-conscious choice when access patterns can vary, because throughput scales automatically without manual provisioning. S3 is object storage and does not provide native POSIX file system behavior. EBS is block storage and is not the right answer for shared, highly available multi-container access across a distributed environment. FSx for Lustre is optimized for specialized high-performance workloads, not general shared configuration and log storage.

AWS Secrets Manager is a fully managed service specifically designed to securely store and automatically rotate database credentials, API keys, and other secrets. Secrets Manager provides built-in integration with Amazon RDS for automatic credential rotation on a configurable schedule without requiring downtime. It also manages the secure distribution of the credentials to authorized services, such as your web servers, using IAM policies. Manual solutions (S3, files, cron jobs) do not provide the same level of automation, audit, or security.

Reference Extract from AWS Documentation / Study Guide:

" AWS Secrets Manager enables you to rotate, manage, and retrieve database credentials securely. It supports automatic rotation of secrets for supported AWS databases without requiring application downtime. "

IAM Access Analyzer analyzes permissions granted using policies to determine what resources are shared with an external entity, and helps identify excessive permissions or least privilege violations across all accounts in an AWS Organization. It is specifically designed for reviewing and refining IAM permissions with minimal administrative effort.

AWS Documentation Extract:
