A large organization with multiple AWS accounts under AWS Organizations needs to audit S3 access using the AWS CLI, monitor activity across all S3 buckets for issues, and prevent account users from disabling CloudTrail. What configuration satisfies these requirements?

The correct option leverages an organization-level CloudTrail, which is crucial for centralized auditing across multiple AWS accounts and prevents individual account users from disabling CloudTrail. Delivering logs to CloudWatch in the management account provides a central repository. Enabling S3 data event logging captures all S3 access activity. CloudWatch anomaly detection across accounts is a suitable service for monitoring issues. CloudWatch Metrics Insights allows for SQL queries on CloudTrail-derived metrics, fulfilling the audit requirement. Incorrect options: Creating a CloudTrail in each account doesn't prevent users from disabling it and complicates centralized management. GuardDuty is for threat detection, not specifically for auditing CloudTrail-derived metrics. Using CloudWatch anomaly detection in each account is less efficient than a centralized approach for an organization. Querying CloudTrail-derived metrics with Athena is possible but CloudWatch Metrics Insights is a more direct fit for querying metrics within CloudWatch. Building a custom anomaly detection solution is generally more complex and less efficient than using AWS-managed services like CloudWatch anomaly detection.
