ACE Practice Question: Your organization uses VPC Service Controls to…
This ACE practice question tests your understanding of your organization uses vpc service controls to…. 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.
Your organization uses VPC Service Controls to protect BigQuery and Cloud Storage. A data pipeline service account needs to read from a protected Cloud Storage bucket and write results to a protected BigQuery dataset. Both resources are in the same perimeter. The service account is outside the perimeter (it runs in a Cloud Run service in a different project). How do you grant the pipeline 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
Add the Cloud Run project to the VPC Service Controls perimeter.
Adding the entire Cloud Run project to the perimeter allows all identities in that project to access perimeter resources — violating least privilege. An ingress rule is more targeted.
B
Distractor review
Grant the service account `roles/bigquery.admin` and `roles/storage.admin` to bypass the perimeter restrictions.
IAM permissions are evaluated after VPC-SC perimeter checks. Even with admin roles, a request denied by the perimeter will fail. IAM cannot override VPC-SC.
C
Best answer
Create an Ingress Rule in the VPC-SC perimeter that allows the service account from the external project to access the specific BigQuery and Storage resources.
Ingress rules in VPC Service Controls allow fine-grained external access: specify the source identity (SA), source project, and which services/resources can be accessed inside the perimeter.
D
Distractor review
Move the Cloud Run service into a VPC and set up VPC peering to the perimeter VPC.
VPC peering addresses network connectivity but not VPC Service Controls access. VPC-SC controls are identity and context-based, not network-level.
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: Create an Ingress Rule in the VPC-SC perimeter that allows the service account from the external project to access the specific BigQuery and Storage resources. — VPC Service Controls perimeters restrict API access based on identity and context. To allow an external service account to access resources inside a perimeter, you create an Access Policy with an Ingress Rule that: specifies the external project and service account as the identity, allows access to the specific services (storage.googleapis.com, bigquery.googleapis.com) and resources inside the perimeter. This is more precise than adding the SA to the perimeter as a trusted identity.
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.
