DBS-C01 Management and Operations Practice Question
A company is using Amazon RDS for MariaDB. The database administrator wants to monitor the database for slow queries. Which TWO services can be used to achieve this? (Choose TWO.)
⚠ Common exam trap
Many candidates confuse Enhanced Monitoring (OS-level metrics) with Performance Insights (database-level query analysis) or assume CloudTrail can capture database queries, when in fact CloudTrail only records AWS API calls, not SQL statements.

Correct answer & explanation
✓
Amazon RDS Performance Insights
Amazon RDS Performance Insights (Option A) is correct because it provides a database performance tuning and monitoring feature that visualizes database load and allows you to identify and analyze slow queries by filtering on SQL statements, waits, and hosts. Amazon CloudWatch Logs (Option C) is correct because you can enable the slow query log for MariaDB and publish those logs to CloudWatch Logs, then use CloudWatch Logs Insights to query and filter for slow queries based on execution time.
