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.
A company is using Cloud SQL for MySQL to store customer data subject to SOX compliance. They need to ensure that all database changes are audited and that logs are immutable. They have enabled audit logs and exported them to a Cloud Storage bucket. However, the auditor discovers that some logs were deleted from the bucket. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The Cloud Storage bucket has a lifecycle rule that deletes objects after a set number of days.
Option D is correct because Cloud Storage lifecycle rules can automatically delete objects after a specified number of days. If a lifecycle rule is configured on the bucket, it would delete audit logs regardless of the export process, making them unavailable to the auditor. This is the most likely cause of logs being deleted from the bucket, as the other options do not explain actual deletion of already-exported objects.
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.
✗
The log sink filter is excluding certain events, causing incomplete export.
Why it's wrong here
Filter causes omission, not deletion of already exported logs.
✗
The bucket has retention policy enabled, which prevents deletion until the retention period expires.
Why it's wrong here
Retention policy would prevent deletion, not cause it.
✗
The service account used for export does not have the storage.objects.delete permission.
Why it's wrong here
Lack of delete permission would prevent deletion, not cause it.
✓
The Cloud Storage bucket has a lifecycle rule that deletes objects after a set number of days.
Why this is correct
If a lifecycle rule is set to delete objects, logs can be automatically removed, violating immutability requirements.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the distinction between features that prevent deletion (retention policies, lock) versus features that cause deletion (lifecycle rules), and candidates mistakenly assume that enabling audit logs or exporting to a bucket guarantees immutability without considering bucket-level configurations.
Detailed technical explanation
How to think about this question
Cloud Storage lifecycle rules are defined as JSON or XML policies that specify actions (e.g., Delete, SetStorageClass) based on conditions like age, creation date, or storage class. When a lifecycle rule with a Delete action and an age condition (e.g., 30 days) is applied, objects older than that threshold are automatically removed by the backend, without any manual intervention. This is a common misconfiguration when setting up audit log buckets, as administrators may inadvertently add a lifecycle rule for cost management without realizing it will delete compliance-critical logs.

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.
