This ACE practice question tests your understanding of a platform team wants to define a formal service…. 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 platform team wants to define a formal service level objective (SLO) for their API: 99.9% of requests must succeed (HTTP 2xx) over a 30-day rolling window. Which Cloud Monitoring feature tracks this?

A platform team wants to define a formal service level objective (SLO) for their API: 99.9% of requests must succeed (HTTP 2xx) over a 30-day rolling window. Which Cloud Monitoring feature tracks this?

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

Distractor review

Set an uptime check target of 99.9% in Cloud Monitoring

Uptime checks verify endpoint availability from external probes — they measure uptime (reachability), not success rate of actual user requests.

B

Distractor review

Create an alerting policy with a 99.9% threshold on the request success metric

An alerting policy triggers when a metric crosses a threshold at a point in time — it doesn't calculate rolling compliance over a 30-day window like an SLO does.

C

Best answer

Define a Cloud Monitoring SLO with a 99.9% availability target over a 30-day rolling window

Cloud Monitoring SLOs track error budget consumption over a rolling window and alert on burn rate — specifically designed for this use case.

D

Distractor review

Build a BigQuery dashboard showing 30-day average success rates from exported logs

A BigQuery dashboard is a manual reporting tool — it doesn't provide burn rate alerts or error budget tracking like a Cloud Monitoring SLO does.

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: Define a Cloud Monitoring SLO with a 99.9% availability target over a 30-day rolling window — Cloud Monitoring SLOs allow teams to define availability and latency SLOs against request-based or window-based metrics. For a 99.9% success rate SLO, the team creates a request-based SLO using the load balancer's request count metric, filtering by 2xx responses as 'good' requests.

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.
