- A
Apply a retention policy to each object individually using object holds.
Why wrong: Object holds prevent deletion but are manual and not suitable for all objects; a bucket-level retention policy is preferred.
- B
Use VPC Service Controls to restrict access to the bucket to only authorized compliance personnel.
Why wrong: VPC Service Controls prevent data exfiltration but do not enforce data immutability or retention.
- C
Modify the lifecycle rule to delete objects after 2555 days instead of 365 days.
Why wrong: Lifecycle rules do not prevent manual deletion; objects could still be deleted before the retention period ends.
- D
Enable Bucket Lock on the bucket and configure a retention policy of 7 years.
Bucket Lock enforces a retention policy that prevents object deletion or modification until the retention period expires, overriding lifecycle rules.
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 financial services company must store customer transaction records for 7 years to comply with SEC regulations. They currently use Cloud Storage with a lifecycle rule that deletes objects after 365 days. The compliance team needs to ensure that records are immutable and cannot be deleted or modified before the retention period expires. What should the security engineer do?
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
Enable Bucket Lock on the bucket and configure a retention policy of 7 years.
Option D is correct because Bucket Lock is the only Google Cloud Storage feature that enforces immutability by preventing object deletion or modification for a specified retention period. By enabling Bucket Lock and configuring a 7-year retention policy, the company ensures compliance with SEC regulations, as objects cannot be deleted or overwritten even by the bucket owner or lifecycle rules. This overrides the existing 365-day lifecycle rule because retention policies take precedence over lifecycle deletion actions.
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 access controls (like VPC Service Controls or IAM) and data immutability features, leading candidates to confuse restricting access with enforcing retention.
Detailed technical explanation
How to think about this question
Bucket Lock uses a retention policy that, once locked, cannot be shortened or removed, ensuring objects are immutable for the configured duration. Under the hood, Google Cloud Storage enforces this by preventing any delete or overwrite requests on objects within the retention period, even if those requests come from the bucket owner or service accounts. A real-world scenario is financial audits where regulators require proof that records were not tampered with; Bucket Lock provides a verifiable, WORM (Write Once, Read Many) compliance model.
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.
