Correct answer & explanation
✓
Amazon CloudWatch with enhanced monitoring for RDS
Amazon CloudWatch with enhanced monitoring provides detailed OS-level metrics for RDS (CPU, memory, disk I/O, and network), along with EC2 metrics, enabling analysis of performance bottlenecks in SAP BusinessObjects. Option A (AWS Trusted Advisor) offers best-practice recommendations, not performance analysis. Option B (AWS CloudTrail) audits API calls, which is unrelated to performance. Option C (AWS X-Ray) is designed for tracing requests in distributed applications, not for database-level performance monitoring.
