The answer is to review Amazon RDS events, enable Performance Insights, and enable Enhanced Monitoring. These three steps are correct because they focus on gathering diagnostic data rather than applying fixes: Performance Insights identifies the specific queries consuming CPU, Enhanced Monitoring provides OS-level metrics like CPU and memory usage at the instance level, and RDS events reveal any underlying maintenance or failover activities that could trigger a CPU spike. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this question tests your ability to distinguish between diagnostic actions and remedial actions—a common trap is confusing a solution (like scaling the instance) with a diagnostic step. The exam often presents plausible but incorrect options that are valid operational actions but not diagnostic in nature. A useful memory tip is “D-E-R”: Diagnose with Events, Enhanced Monitoring, and RDS Performance Insights—never jump to a remedy before you know the root cause.
SAP-C02 Continuous Improvement for Existing Solutions Practice Question
This SAP-C02 practice question tests your understanding of continuous improvement for existing solutions. 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 runs a critical database on Amazon RDS for PostgreSQL. The database is experiencing performance degradation due to high CPU utilization. The operations team wants to analyze the root cause. Which THREE steps should the team take to diagnose 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 Enhanced Monitoring to view OS-level metrics such as CPU and memory usage.
Options A, B, and D are correct. Enabling Performance Insights helps identify queries causing load. Enabling enhanced monitoring provides OS-level metrics. Using RDS events can indicate maintenance or issues. C is wrong because increasing instance size is a remedy, not a diagnostic step. E is wrong because Multi-AZ is for high availability, not performance diagnosis.
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 Enhanced Monitoring to view OS-level metrics such as CPU and memory usage.
Why this is correct
Enhanced Monitoring provides detailed OS metrics.

✗
Increase the instance size to provisioned IOPS to handle the load.
Why it's wrong here
This is a remedial action, not a diagnostic step.
✓
Enable Amazon RDS Performance Insights to identify the queries consuming the most CPU.
Read the scenario before looking for a memorised answer.
✓
Review Amazon RDS events to check for any recent maintenance or failover activities.
Why this is correct
RDS events can reveal underlying causes like patching.

✗
Enable Multi-AZ deployment for automatic failover.
Why it's wrong here
Multi-AZ improves availability, not performance diagnosis.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
