This ACE practice question tests your understanding of a team stores sensitive configuration files in…. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 team stores sensitive configuration files in Cloud Storage that internal services download at startup. External partners occasionally need time-limited access to specific files without creating GCP accounts. Which feature grants temporary access without modifying bucket permissions?

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

Enable uniform bucket-level access and create a public IAM binding for 24 hours

IAM bindings don't have built-in expiration (without IAM Conditions) — and uniform access public bindings expose all objects, not specific files.

B

Distractor review

Create a temporary GCP service account for the partner and share its JSON key

Creating service accounts for external partners adds IAM management overhead and leaves long-lived credentials in external hands — signed URLs are the purpose-built alternative.

C

Best answer

Generate a Signed URL for the specific files with the required expiration time

Signed URLs are cryptographically signed, time-limited URLs that grant access to specific Cloud Storage objects. Partners access the file via the URL without needing GCP credentials.

D

Distractor review

Make the specific files publicly readable and share the direct URL

Making files public grants unlimited access to anyone — signed URLs provide the same access but with a time limit and without modifying bucket permissions.

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.
