- A
Enable Cloud Data Loss Prevention (DLP) to automatically redact sensitive data before it is displayed in the console.
Why wrong: DLP does not block access; it only transforms data after access is granted.
- B
Reconfigure the VPC Service perimeter to use a more restrictive set of allowed IP ranges.
Why wrong: The IP address belonged to a personal laptop, which could be anywhere; IP ranges cannot differentiate between corporate and personal devices.
- C
Activate Access Transparency logs and create a log-based alert to notify security of anomalous access.
Why wrong: Logging and alerting are detective controls, not preventive; they allow the access to happen first.
- D
Add a context-aware access level to the VPC Service perimeter that requires a corporate device policy (e.g., OS version, disk encryption).
This enforces device trust, blocking access from non-corporate devices while still respecting the VPC SC perimeter.
Quick Answer
The correct answer is to add a context-aware access level to the VPC Service perimeter that requires a corporate device policy. This works because VPC Service Controls (VPC SC) can integrate with Access Context Manager to enforce conditions beyond network origin, such as requiring a device to meet specific corporate standards like verified OS version and disk encryption. Even if a user is authenticated and the request comes from an allowed IP or VPC, the perimeter will block access from unmanaged personal laptops that fail the device policy check. On the Google Professional Cloud Security Engineer exam, this scenario tests your understanding that VPC SC perimeters are not just about network boundaries—they can be layered with context-aware access levels to enforce device trust. A common trap is assuming that restricting by VPC or IP alone is sufficient, but the exam emphasizes that authenticated users can bypass network controls via the Cloud Console. Remember the mnemonic: "Perimeter plus policy—block the laptop, not just the network."
PCSE Ensuring data protection Practice Question
This PCSE practice question tests your understanding of ensuring data protection. 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 large enterprise runs analytics workloads on BigQuery containing sensitive financial data. They have implemented VPC Service Controls (VPC SC) to create a perimeter around the BigQuery dataset, allowing access only from a specific VPC network. Despite this, security auditors discovered that data was accessed from an IP address outside the perimeter. After investigation, they found the access originated from a user's personal laptop using the Google Cloud Console. The company's security policy requires that sensitive data can only be accessed from corporate-managed devices. What should they do to prevent this type of access?
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
Add a context-aware access level to the VPC Service perimeter that requires a corporate device policy (e.g., OS version, disk encryption).
Option D is correct because VPC Service Controls can integrate with Access Context Manager to enforce context-aware access levels. By adding a level that requires a corporate device policy (e.g., verified OS version, disk encryption status), access from unmanaged personal laptops is blocked at the perimeter boundary, even if the user is authenticated. This directly addresses the security policy requirement that sensitive data must only be accessible from corporate-managed devices.
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
The trap here is that candidates confuse logging/monitoring (Option C) or data masking (Option A) with preventive access control, or they assume IP-based restrictions (Option B) are sufficient when the real requirement is device identity enforcement.
Detailed technical explanation
How to think about this question
Access Context Manager evaluates device attributes (e.g., Chrome OS version, disk encryption status, device serial number) using the BeyondCorp Alliance or Google's device management integrations (e.g., with Jamf, Microsoft Intune). The access level is enforced at the VPC Service Controls perimeter boundary, meaning the request is denied before it reaches the BigQuery API, providing a true zero-trust gate. A common subtlety is that the device policy must be configured in the organization's device management system and the user must be logged into Chrome with a managed profile for the attributes to be passed.
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 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.
