The answer is to enable Performance Insights for the RDS instance and analyze the database load. Performance Insights provides a real-time database load visualization broken down by waits, SQL queries, hosts, and users, allowing you to pinpoint the exact bottleneck causing high latency during peak hours. On the AWS Certified Database Specialty DBS-C01 exam, this scenario tests your ability to differentiate between monitoring services: CloudWatch shows aggregated metrics but lacks the granular, session-level detail needed for root cause analysis, while AWS Config and Amazon Inspector serve entirely different purposes for compliance and security. A common trap is choosing CloudWatch Metrics Dashboard because it’s familiar, but remember that Performance Insights is purpose-built for deep database performance troubleshooting. Memory tip: “PI for DB load, CW for metrics overload”—Performance Insights reveals the “why” behind the latency, not just the “what.”
DBS-C01 Monitoring and Troubleshooting Practice Question
This DBS-C01 practice question tests your understanding of monitoring and troubleshooting. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 company is using Amazon RDS for MySQL with Multi-AZ deployment. The application team reports increased latency during peak hours. Which AWS service should the database specialist use to identify the root cause?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable Performance Insights for the RDS instance and analyze the database load.
Option B is correct because Performance Insights provides database performance metrics and helps identify bottlenecks. Option A is wrong because CloudWatch Metrics Dashboard shows aggregated metrics but does not provide detailed database performance analysis. Option C is wrong because AWS Config is for resource configuration auditing. Option D is wrong because Amazon Inspector is for security assessments.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Enable Performance Insights for the RDS instance and analyze the database load.
Read the scenario before looking for a memorised answer.
✗
Enable AWS Config to track configuration changes to the RDS instance.
Why it's wrong here
AWS Config is for resource configuration auditing, not performance analysis.
✗
Use the CloudWatch Metrics Dashboard to analyze database connections.
Why it's wrong here
CloudWatch Metrics Dashboard shows aggregated metrics but not detailed database performance.
✗
Run an Amazon Inspector assessment on the RDS instance.
Why it's wrong here
Amazon Inspector is for security assessments, not performance monitoring.
Common exam traps
Common exam trap: answer the scenario, not the keyword
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.

Detailed technical explanation
How to think about this question
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.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company is running a production Amazon RDS for MySQL DB instance. The application team reports intermittent high latency and connection timeouts. A quick check shows that the DB instance's CPU utilization is consistently above 90% during peak hours. The database size is 500 GB and the instance class is db.r5.large. Which combination of actions should a database specialist take to resolve the performance issue?
medium
A.Increase the allocated storage to 1 TB and enable auto-scaling for storage.
✓ B.Scale up the DB instance to db.r5.xlarge and review slow query logs to optimize poorly performing queries.
C.Enable Multi-AZ and increase the allocated storage to 1 TB to improve I/O performance.
D.Enable Performance Insights and create a CloudWatch alarm to notify when CPU exceeds 80%.
Why B: Option B is correct because scaling up the DB instance to db.r5.xlarge increases compute capacity, which directly addresses high CPU utilization. Additionally, reviewing slow query logs can identify inefficient queries causing CPU spikes. Option A is wrong because enabling Multi-AZ does not increase compute capacity; it only provides high availability. Option C is wrong because enabling Performance Insights helps diagnose but does not resolve the issue. Option D is wrong because increasing the allocated storage does not affect CPU performance.
Variation 2. A company is running a production Amazon RDS for MySQL DB instance. The application team reports intermittent connection timeouts. The DBA notices that the DB instance's CPU utilization spikes to 100% during these times. Which metric should be monitored to determine if the issue is due to a specific query?
medium
A.DatabaseConnections
B.NetworkThroughput
C.ReadIOPS
✓ D.Queries (engine-specific counter)
Why D: Option D is correct because the RDS for MySQL engine-specific counter 'Queries' reflects the number of queries executed. Option A is wrong because DatabaseConnections shows connections, not query performance. Option B is wrong because ReadIOPS measures disk I/O, not query volume. Option C is wrong because NetworkThroughput measures network traffic.
