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.

Exhibit

Refer to the exhibit.

```json
{
  "kind": "storage#bucket",
  "name": "compliance-bucket",
  "retentionPolicy": {
    "retentionPeriod": "31536000",
    "effectiveTime": "2024-01-01T00:00:00Z",
    "isLocked": true
  },
  "iamConfiguration": {
    "uniformBucketLevelAccess": {
      "enabled": true
    }
  }
}
```

An organization is configuring a Cloud Storage bucket for a regulated workload. The bucket configuration shown in the exhibit was applied. Which compliance requirement is this configuration primarily designed to address?

Exhibit

Refer to the exhibit.

```json
{
  "kind": "storage#bucket",
  "name": "compliance-bucket",
  "retentionPolicy": {
    "retentionPeriod": "31536000",
    "effectiveTime": "2024-01-01T00:00:00Z",
    "isLocked": true
  },
  "iamConfiguration": {
    "uniformBucketLevelAccess": {
      "enabled": true
    }
  }
}
```

A
Data retention and immutability.
The retentionPolicy with isLocked=true enforces a mandatory retention period, making objects immutable until the retention period expires.
B
Encryption at rest using customer-managed encryption keys (CMEK).
Why wrong: No encryption settings are present in the exhibit; CMEK would be specified separately.
C
Access transparency for data access.
Why wrong: Access transparency requires specific configuration and is not shown; the exhibit focuses on retention and IAM.
D
Data residency within a specific geographic region.
Why wrong: The bucket configuration does not include location settings; residency is enforced via organization policies or bucket location.

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

✓

Data retention and immutability.

The bucket configuration includes object versioning enabled and a retention policy with a retention period. This combination ensures that objects cannot be deleted or overwritten before the retention period expires, addressing data retention and immutability requirements. This is a common compliance need for regulated workloads where data must be preserved in its original state for a defined duration.

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 bucket-level retention policies (which enforce immutability) and encryption or access control settings, leading candidates to confuse data retention with encryption at rest or data residency.

Trap categories for this question

Command / output trap
Access transparency requires specific configuration and is not shown; the exhibit focuses on retention and IAM.

Detailed technical explanation

How to think about this question

Object versioning in Cloud Storage retains all versions of an object, preventing permanent deletion. A retention policy uses a lock mechanism that, once locked, cannot be shortened or removed, enforcing a minimum retention period for all objects in the bucket. This is critical for compliance with regulations like SEC Rule 17a-4 or FINRA, which require immutable storage for electronic records.

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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
