The answer is to enable the slow query log and analyze the queries. This is the correct action because intermittent connection timeouts in Amazon RDS MySQL, especially when paired with CloudWatch spikes in DatabaseConnections and CPU Utilization during peak hours, are classic symptoms of poorly optimized, long-running queries holding locks or consuming resources. By enabling the slow query log, you capture queries that exceed a defined execution time, allowing you to pinpoint the exact SQL statements causing the bottleneck. On the AWS Certified Database Specialty DBS-C01 exam, this scenario tests your understanding that performance-related timeouts require query-level diagnosis, not infrastructure changes like Multi-AZ failover or adding read replicas—a common trap where candidates confuse high availability with performance tuning. Remember: when you see high CPU and connections, think “slow queries first, not failover.” A useful memory tip is “Log the slow, fix the flow.”
DBS-C01 Monitoring and Troubleshooting Practice Question
This DBS-C01 practice question tests your understanding of monitoring and troubleshooting. 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 company is using Amazon RDS for MySQL with Multi-AZ deployment. The application team reports intermittent connection timeouts. CloudWatch shows increased DatabaseConnections and CPU Utilization during peak hours. Which action should the database specialist take to troubleshoot the issue?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable slow query log and analyze queries.
Option B is correct because enabling slow query log helps identify long-running queries causing high CPU and connections. Option A is wrong because Multi-AZ failover does not resolve performance issues. Option C is wrong because enhancing CloudWatch metrics does not directly fix timeouts. Option D is wrong because read replicas are for read scaling, not for reducing connection timeouts on the primary.
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.
✗
Add enhanced monitoring to collect additional metrics.
Why it's wrong here
Enhanced monitoring provides more data but does not resolve the issue.
Read the scenario before looking for a memorised answer.
✗
Create a read replica and redirect read traffic.
Why it's wrong here
Read replicas are for read offloading, not for reducing connection timeouts on the primary.
✗
Failover to the standby instance to refresh connections.
Why it's wrong here
Failover does not address the underlying performance issue.
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.
