PCSE Supporting compliance requirements Practice Question
This PCSE practice question tests your understanding of supporting compliance requirements. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 company is deploying a multi-region application in Cloud Run and must comply with data residency requirements in the European Union (EU). They want to ensure that only EU-based Cloud Run instances are created. Which approach should they use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set an Organization Policy with constraints/gcp.resourceLocations to restrict allowed regions to EU regions.
Option B is correct because Organization Policies with the `constraints/gcp.resourceLocations` constraint allow administrators to enforce a list of allowed Google Cloud regions for resource creation. By setting this policy to include only EU-based regions (e.g., `europe-west1`, `europe-west4`), the company ensures that Cloud Run instances cannot be created outside the EU, directly meeting data residency compliance requirements. This is a preventive control that applies at the project or folder level, overriding any developer choices.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Add a label to the Cloud Run service specifying the region and rely on developers to follow it.
Why it's wrong here
Labels are not enforcement; they are metadata.
✓
Set an Organization Policy with constraints/gcp.resourceLocations to restrict allowed regions to EU regions.
Why this is correct
This policy will prevent creation of Cloud Run services outside the allowed regions.

Read the scenario before looking for a memorised answer.
✗
Use VPC Service Controls to limit access to the Cloud Run service from outside the EU.
Why it's wrong here
VPC Service Controls prevent data exfiltration, not resource creation location.
✗
Configure VPC Firewall rules to only allow egress to EU IP addresses.
Why it's wrong here
Firewall rules control network traffic, not where the service is deployed.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse network-level controls (VPC Service Controls, Firewall rules) with resource location enforcement, thinking that restricting access or egress to EU IPs is equivalent to ensuring resources are physically created in EU regions.
Detailed technical explanation
How to think about this question
The `constraints/gcp.resourceLocations` organization policy uses a list of allowed region names (e.g., `in:us-central1` or `in:europe-west1`) and is evaluated at resource creation time by Google Cloud's Resource Manager. For Cloud Run, this policy applies to the service's region selection, and if a region is not in the allowed list, the API call fails with a `PERMISSION_DENIED` error. Note that this policy does not affect data storage locations of dependent services (like Cloud SQL or Cloud Storage) unless those services also respect the same constraint; for full data residency, you must also apply the policy to all relevant resource types.

Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→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.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
