The answer is Enhanced Monitoring, specifically the cpuUtilization per process metric, because it provides OS-level visibility into individual process-level CPU consumption on the RDS instance. While CloudWatch’s standard CPUUtilization metric confirms high overall usage, it cannot isolate a specific query; Enhanced Monitoring reveals which operating system process (such as sqlservr.exe) is consuming the most CPU, allowing you to correlate that process with a particular query using SQL Server DMVs or Performance Insights. On the AWS Certified Database Specialty DBS-C01 exam, this question tests your understanding that CloudWatch alone lacks query-level granularity—Enhanced Monitoring bridges the gap by surfacing per-process metrics, a common trap where candidates mistakenly choose DatabaseConnections. Remember: to find the query causing high CPU, start with Enhanced Monitoring’s per-process data, then drill into Performance Insights or sys.dm_exec_requests. Memory tip: “Process first, query second”—Enhanced Monitoring shows you the process, not the query text.
DBS-C01 Management and Operations Practice Question
This DBS-C01 practice question tests your understanding of management and operations. 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 database administrator is troubleshooting a performance issue on an Amazon RDS for SQL Server instance. The CPU utilization is consistently above 90%, and the number of database connections is high. Which Amazon CloudWatch metric should be analyzed first to determine if the issue is due to a specific query?

Correct answer & explanation
✓
Enhanced Monitoring (cpuUtilization per process)
While CloudWatch provides metrics like CPUUtilization, the question asks for a metric that helps identify a specific query causing high CPU. CloudWatch does not directly expose query-level metrics; however, enhanced monitoring provides OS-level metrics but not query details. To identify specific queries, you need to use RDS Performance Insights or SQL Server's own DMVs. Among the options, 'DatabaseConnections' is not query-specific. The correct answer is to use Performance Insights, but since it's not listed, the best CloudWatch metric is 'CPUUtilization' to confirm high CPU, but the actual tool for query analysis is not CloudWatch. The question expects 'Enhanced Monitoring' as it gives per-process metrics that can lead to identifying queries if combined with other tools. However, none directly identify a specific query. The closest is Enhanced Monitoring which can show top processes. 'DatabaseConnections' does not help. The correct answer is D because Enhanced Monitoring provides OS-level metrics that can help pinpoint resource-intensive processes that may be running specific queries.
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.
✗
DatabaseConnections
Why it's wrong here
This metric shows the number of connections, but not which queries are causing high CPU.
✗
ReadIOPS
Why it's wrong here
ReadIOPS indicates disk I/O, not directly CPU usage by queries.
✓
Enhanced Monitoring (cpuUtilization per process)
Why this is correct
Enhanced Monitoring provides per-process CPU metrics, which can help identify which process (and thus which query) is consuming the most CPU.
Clue confirmation
The clue word "first" in the question point toward this 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.
