PCSE Supporting compliance requirements Practice Question

This PCSE practice question tests your understanding of supporting compliance requirements. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.

Exhibit

{
  "name": "projects/123/locations/global/perimeters/pci-perimeter",
  "status": {
    "resources": ["projects/123"],
    "restrictedServices": ["bigquery.googleapis.com"],
    "vpcAccessibleServices": {
      "allowedServices": ["storage.googleapis.com"]
    }
  }
}

Refer to the exhibit. A company configured this VPC Service Controls perimeter for a PCI DSS project. The compliance auditor notes that BigQuery data can be accessed from outside the perimeter. Which change must be made to restrict access to BigQuery?

Exhibit

{
  "name": "projects/123/locations/global/perimeters/pci-perimeter",
  "status": {
    "resources": ["projects/123"],
    "restrictedServices": ["bigquery.googleapis.com"],
    "vpcAccessibleServices": {
      "allowedServices": ["storage.googleapis.com"]
    }
  }
}

A
Set the perimeter enforcement mode to enforced instead of dry run
A perimeter in dry run mode logs violations but does not block access; it must be set to enforced to restrict BigQuery.
B
Add storage.googleapis.com to restrictedServices
Why wrong: Storage is allowed for VPC access; adding it would block storage, not fix BigQuery restriction.
C
Move BigQuery to a separate perimeter
Why wrong: Even in a separate perimeter, BigQuery would still need to be enforced; this does not resolve the compliance issue.
D
Add allUsers to the perimeter's access levels
Why wrong: Access levels are for context-aware conditions, not for enforcement of restrictions.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Set the perimeter enforcement mode to enforced instead of dry run

The dry run mode logs violations but does not enforce restrictions, allowing BigQuery data to be accessed from outside the perimeter. Changing the enforcement mode to 'enforced' activates the VPC Service Controls policies, blocking all out-of-perimeter access to the configured services. This directly addresses the auditor's finding by ensuring that only requests from within the perimeter are allowed.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Google Cloud often tests the distinction between 'dry run' and 'enforced' modes, where candidates mistakenly assume that simply adding a service to the perimeter or configuring access levels is sufficient without enabling enforcement.

Detailed technical explanation

How to think about this question

VPC Service Controls uses a 'dry run' mode that logs policy violations via Cloud Audit Logs without blocking traffic, allowing administrators to test policies before enforcement. When set to 'enforced', the perimeter leverages a proxy that intercepts API calls to restricted services and evaluates them against the perimeter's access levels and ingress/egress rules, returning a 403 error for non-compliant requests. This mechanism is critical for PCI DSS compliance because it prevents data exfiltration even if credentials are compromised from outside the trusted network.

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.

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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
