This DOP-C02 practice question tests your understanding of monitoring and logging. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A DevOps engineer is troubleshooting an issue where an Amazon RDS for MySQL instance is experiencing high latency. The engineer wants to identify which queries are causing the problem. Which AWS service should be used?
Amazon RDS Performance Insights
Performance Insights provides per-query performance data to identify problematic queries.
AWS CloudTrail
Why wrong: CloudTrail records API calls, not database queries.
Amazon CloudWatch Metrics
Why wrong: CloudWatch metrics show aggregate database performance, not individual queries.
VPC Flow Logs
Why wrong: VPC Flow Logs capture network traffic, not database queries.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Amazon RDS Performance Insights
Option B is correct because RDS Performance Insights provides a database performance tuning and monitoring feature that allows you to assess the load on your database and determine when and where to take action. Option A is wrong because CloudWatch metrics show aggregate performance, not per-query. Option C is wrong because CloudTrail records API calls. Option D is wrong because VPC Flow Logs capture network traffic.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Trap categories for this question
Command / output trap
CloudWatch metrics show aggregate database performance, not individual queries.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
