ACE Practice Question: An application receives the error 'Permission…

This ACE practice question tests your understanding of an application receives the error 'permission…. 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.

An application receives the error 'Permission denied on resource project [PROJECT_ID] (or it may not exist)' when making an API call with a service account. The service account has the correct IAM role. What else might be missing?

An application receives the error 'Permission denied on resource project [PROJECT_ID] (or it may not exist)' when making an API call with a service account. The service account has the correct IAM role. What else might be missing?

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

The service account needs the Project Owner role to make any API calls

Project Owner is not required — specific predefined roles grant access to specific APIs. The issue is likely the API not being enabled.

B

Distractor review

The service account needs to be in the same organization as the project

Service accounts from different projects (even different organizations) can be granted cross-project IAM roles. There's no same-organization requirement.

C

Distractor review

The service account email must be explicitly allow-listed in the API's configuration

GCP APIs use IAM for access control — there's no separate email allow-list. The issue is API enablement, not an allow-list.

D

Best answer

The relevant GCP API is not enabled in the project

GCP requires the API to be enabled before any service account or user can use it. The error 'or it may not exist' refers to the resource being unreachable because the API is disabled.

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: The relevant GCP API is not enabled in the project — This error often occurs when the API being called is not enabled in the project, not just when IAM permissions are missing. GCP requires both: the relevant API must be enabled in the project AND the service account must have the correct IAM role. 'Or it may not exist' hints at the API not being enabled.

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.
