This ACE practice question tests your understanding of grant a third-party monitoring vendor's 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.

You need to grant a third-party monitoring vendor's service account `roles/monitoring.viewer` on your project, but only for the next 90 days. After 90 days, the access should automatically expire. Which IAM feature enables time-limited access?

You need to grant a third-party monitoring vendor's service account `roles/monitoring.viewer` on your project, but only for the next 90 days. After 90 days, the access should automatically expire. Which IAM feature enables time-limited access?

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 a session duration limit in the vendor's service account settings.

Service account session duration limits apply to credentials generated from the SA (like OAuth tokens), not to the IAM binding's validity period.

B

Distractor review

Grant the role and set a reminder to manually revoke it in 90 days.

Manual reminders are unreliable. IAM Conditions provide automated, policy-enforced expiration with no manual follow-up required.

C

Best answer

Add an IAM Condition with a date/time expression that expires the binding after 90 days.

IAM Conditions support `request.time` comparisons. A condition like `request.time < timestamp('EXPIRY_DATE')` causes the binding to stop granting access after the specified date automatically.

D

Distractor review

Use a temporary service account that is automatically deleted after 90 days via a Cloud Scheduler job.

Deleting the service account is irreversible and operationally complex. IAM Conditions are the purpose-built, simpler solution.

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: Add an IAM Condition with a date/time expression that expires the binding after 90 days. — IAM Conditions allow you to add condition expressions to IAM bindings that restrict when the binding is effective. A date/time condition like `request.time < timestamp('2026-08-17T00:00:00Z')` makes the binding expire on a specific date. After that date, the condition evaluates to false, the binding no longer grants access, and the vendor loses access automatically without requiring manual removal.

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.
