PAS-C01 Technology Practice Question
A company is running an SAP HANA database on an EC2 instance with a large amount of memory. The system is experiencing performance issues during peak loads. Which AWS service should be used to capture detailed performance metrics for analysis?
⚠ Common exam trap
A common mix-up: candidates confuse AWS CloudTrail (auditing) or AWS Config (compliance) with performance monitoring, but the exam specifically tests whether you know that CloudWatch is the only service that captures OS-level and custom performance metrics for EC2 instances.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon CloudWatch
Amazon CloudWatch is the correct service because it provides detailed, customizable performance metrics for EC2 instances, including memory utilization, CPU, disk I/O, and network throughput. For SAP HANA, which is memory-intensive, CloudWatch can capture custom metrics (e.g., via the CloudWatch Agent) to monitor memory pressure and identify bottlenecks during peak loads, enabling performance analysis and scaling decisions.
