Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
CPUUtilization
The correct metrics to proactively identify performance issues in an SAP NetWeaver application server are CPUUtilization (B), Memory utilization via the CloudWatch Agent (C), and DiskQueueDepth (E). CPUUtilization indicates CPU load, Memory utilization shows memory pressure, and DiskQueueDepth reflects I/O bottlenecks. S3 request metrics (A) are for object storage, not the application server itself. VPC Flow Logs (D) capture network traffic metadata, not performance metrics.
