The correct answer is to use a log sink that exports Cloud Audit Logs to a Cloud Storage bucket with a retention policy set to 7 years and Object holds enabled. This solution ensures immutability because Object holds prevent any object deletion or modification, while the retention policy enforces the minimum storage duration required by HIPAA, all with minimal operational overhead by leveraging native GCP features. On the Google Professional Cloud Security Engineer exam, this scenario tests your understanding of log export architecture and compliance controls, often appearing as a trap where candidates mistakenly choose BigQuery or Pub/Sub—but those lack built-in immutability guarantees. Remember the key pairing: retention policy for duration, Object holds for immutability. A useful mnemonic is “Hold the log, lock the clock”—Object holds prevent changes, while the retention policy sets the time lock.
PCSE Supporting compliance requirements Practice Question
This PCSE practice question tests your understanding of supporting compliance requirements. 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 healthcare company must export Cloud Audit Logs to an external SIEM for HIPAA compliance. The logs must be retained for 7 years and be immutable. Which solution meets these requirements with minimal operational overhead?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a log sink to export logs to a Cloud Storage bucket with a retention policy of 7 years and Object holds enabled.
Option D is correct because Cloud Storage buckets support Object holds, which prevent object deletion or modification, ensuring immutability. A retention policy set to 7 years enforces the minimum retention period required by HIPAA. This combination meets compliance needs with minimal operational overhead, as it leverages native GCP features without requiring custom infrastructure or manual management.
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.
✗
Configure a log sink to send logs to an on-premises syslog server via VPN.
Why it's wrong here
This adds management overhead and does not leverage cloud-native immutable storage.
✗
Create a Pub/Sub sink with a retention policy that delivers logs to a custom application.
Why it's wrong here
Pub/Sub does not provide long-term retention by itself; you need to store messages elsewhere.
✗
Stream audit logs to BigQuery using a log sink, and set table expiration to 7 years.
Why it's wrong here
BigQuery tables can be deleted or altered, so immutability is not guaranteed.
✓
Use a log sink to export logs to a Cloud Storage bucket with a retention policy of 7 years and Object holds enabled.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that BigQuery or Pub/Sub can provide long-term immutable storage, but candidates must recognize that Cloud Storage with Object holds is the only native GCP service that offers both enforced retention and immutability without custom development.
Detailed technical explanation
How to think about this question
Cloud Storage Object holds use a boolean flag that prevents an object from being deleted or overwritten until the hold is removed, even if the bucket has a lifecycle policy. Retention policies enforce a minimum retention period, but Object holds provide an additional layer of immutability by blocking deletion or modification regardless of the retention policy. In practice, combining a retention policy with Object holds ensures that logs cannot be tampered with during the required 7-year period, satisfying HIPAA's audit log integrity requirements.

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.
