The correct actions are to enable Enhanced Monitoring and Performance Insights. Enhanced Monitoring provides OS-level metrics like CPU, memory, and disk I/O, which is essential for diagnosing high CPU utilization caused by operating system processes such as backups or patching, rather than database queries alone. Performance Insights then identifies the specific high-load queries consuming database resources, giving you the full picture. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this pairing tests your understanding that RDS troubleshooting requires both the OS layer (Enhanced Monitoring) and the database layer (Performance Insights)—a common trap is to rely only on CloudWatch, which lacks the granularity of OS processes. For a memory tip, think “OS and Queries”: Enhanced Monitoring shows the OS, Performance Insights shows the queries.
SOA-C02 Monitoring, Logging, and Remediation Practice Question
This SOA-C02 practice question tests your understanding of monitoring, logging, and remediation. 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.
Which TWO actions should a SysOps admin take to troubleshoot an Amazon RDS instance that is experiencing high CPU utilization? (Choose 2.)
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
Option A is correct because Enhanced Monitoring provides OS-level metrics (e.g., CPU, memory, disk I/O) for the RDS instance, which helps identify resource contention at the operating system level. This granularity is essential for diagnosing high CPU utilization that may be caused by OS processes (e.g., backup, patching) rather than database queries alone.
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
Why this is correct
Enhanced Monitoring gives per-process CPU usage.
Related concept
Read the scenario before looking for a memorised answer.
✗
Enable Multi-AZ to distribute the load
Why it's wrong here
Multi-AZ provides failover, not load distribution for CPU.
✗
Delete the slow query log to free up CPU
Why it's wrong here
Deleting logs does not reduce CPU usage.
✓
Enable Performance Insights to identify high-load queries
Why this is correct
Performance Insights shows database load and queries.
Related concept

✗
Increase the instance size to reduce CPU utilization
Why it's wrong here
Scaling up is a resolution, not a troubleshooting step.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Multi-AZ with read replicas, assuming it distributes load, or they think deleting logs frees CPU, when in fact logs are written asynchronously and have negligible CPU impact.
Detailed technical explanation
How to think about this question
Enhanced Monitoring uses the CloudWatch agent to collect metrics from the RDS hypervisor at intervals as low as 1 second, providing visibility into CPU steal time, memory pressure, and disk queue depth. Performance Insights, on the other hand, uses a database load graph to pinpoint specific SQL statements causing high DB load, leveraging the wait-event model (e.g., CPU, IO, lock waits) to identify bottlenecks. In practice, combining these two tools allows an admin to differentiate between OS-level resource exhaustion and query-level inefficiency.
KKey Concepts to Remember

Eliminate answers that are true in general but not in this case.
TExam Day Tips
→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.
