Correct answer & explanation
✓
Amazon RDS Performance Insights
Amazon RDS Performance Insights provides database performance tuning and monitoring with query-level metrics, enabling identification of resource-intensive queries. Option B is wrong because CloudWatch Logs collects log files but does not capture query-level performance. Option C is wrong because Enhanced Monitoring provides OS-level metrics (CPU, memory) but not query-level details. Option D is wrong because CloudTrail records AWS API activity, not database queries.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Amazon RDS Performance Insights
Why this is correct
Performance Insights offers a dashboard that visualizes database load and identifies top queries by resource consumption, making it the right tool for analyzing slow queries.
- ✗
Amazon CloudWatch Logs
Why it's wrong here
CloudWatch Logs can aggregate database logs but lacks the query-level performance breakdown needed for this task.
- ✗
Amazon RDS Enhanced Monitoring
Why it's wrong here
Enhanced Monitoring gives OS-level metrics such as CPU and memory usage, not query-specific performance data.
- ✗
AWS CloudTrail
Why it's wrong here
CloudTrail tracks API calls for governance and auditing, not database query performance.
