The answer is to use Amazon RDS Performance Insights to identify resource-intensive queries in Aurora MySQL. Performance Insights offers a real-time dashboard that visualizes database load and breaks it down by SQL queries, allowing you to pinpoint which specific statements are consuming the most CPU, memory, or I/O resources. On the AWS Certified Database Specialty DBS-C01 exam, this question tests your ability to distinguish between monitoring tools: Enhanced Monitoring provides OS-level metrics like CPU and memory usage but cannot show individual queries, while Performance Insights directly surfaces the top SQL by load. A common trap is confusing Enhanced Monitoring with query-level analysis, so remember that Performance Insights is the go-to for drilling into query performance and identifying long-running or high-impact SQL. Memory tip: think “PI for SQL” — Performance Insights pinpoints problematic queries.
DBS-C01 Management and Operations Practice Question
This DBS-C01 practice question tests your understanding of management and operations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 Aurora MySQL-Compatible Edition. The database is experiencing performance degradation due to long-running queries. The DBA needs to identify the queries that are consuming the most resources. Which action should be taken?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Amazon RDS Performance Insights to identify the top SQL queries.
Option C is correct because Performance Insights provides a dashboard to analyze database performance and identify top SQL queries by load. Option A is wrong because RDS Enhanced Monitoring shows OS metrics, not specific queries. Option B is wrong because CloudWatch Logs collects logs but does not analyze query performance. Option D is wrong because the slow query log must be enabled and analyzed separately.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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 and review the OS process list.
Why it's wrong here
Enhanced Monitoring shows OS-level metrics, not database query details.
✗
Enable the slow query log and use a third-party tool to analyze it.
Why it's wrong here
This is possible but not as direct as Performance Insights.
✓
Use Amazon RDS Performance Insights to identify the top SQL queries.
Why this is correct
Performance Insights helps identify queries that are consuming the most resources.
Related concept
Static NAT maps one inside address to one outside address.
✗
Enable CloudWatch Logs for the DB instance and search for errors.
Why it's wrong here
CloudWatch Logs records logs but does not analyze query performance.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Trap categories for this question
Command / output trap
Enhanced Monitoring shows OS-level metrics, not database query details.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related DBS-C01 NAT questions on configuration and troubleshooting.
