ACE Practice Question: A Cloud Run service handles payment processing
This ACE practice question tests your understanding of a cloud run service handles payment processing. 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 Cloud Run service handles payment processing. A monitoring alert shows the service is experiencing 3-second P99 latency, up from its normal 200ms. The team wants to find the slowest individual requests in the last hour. Which tool provides per-request latency data?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Cloud Trace — sort traces by latency in the last hour
Cloud Trace records individual request traces with full timing breakdown. Sorting by latency in the Trace list immediately surfaces the slowest requests.
B
Distractor review
Cloud Logging — filter for requests with duration > 3s
Cloud Logging may contain request log entries with duration fields, but the request format varies. Cloud Trace is specifically designed for latency analysis.
C
Distractor review
Cloud Monitoring — check the request_latencies metric distribution
Cloud Monitoring shows aggregate latency distributions (percentiles) — it doesn't show individual request details or allow drilling into specific slow requests.
D
Distractor review
Cloud Profiler — view the slowest functions in the last hour
Cloud Profiler shows CPU/memory consumption within the application process — it doesn't show individual request-level latency broken down by request.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this ACE question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Cloud Trace — sort traces by latency in the last hour — Cloud Trace stores per-request timing data for each invocation. In the Trace list view, teams can sort by latency and filter by time range to find the slowest individual requests and see where the time was spent within each request.
What should I do if I get this ACE question wrong?
Identify which ACE exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.
