- A
Object Lifecycle rule with Delete action after 5 years
Why wrong: Lifecycle rules delete objects, they do not prevent deletion.
- B
Retention Policy on the bucket set to 5 years
Retention policies ensure objects cannot be deleted or replaced until the retention period expires.
- C
Object Hold (temporal)
Why wrong: Object Hold is placed on individual objects for indefinite retention, not time-based.
- D
Versioning enabled
Why wrong: Versioning keeps multiple versions but does not prevent deletion of the current version.

PDE Storing the Data Practice Question
This PDE practice question tests your understanding of storing the data. 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 data engineer wants to store archived log files in Cloud Storage with a retention policy that prevents deletion for 5 years. Which feature should they use?
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
✓
Retention Policy on the bucket set to 5 years
A retention policy on a Cloud Storage bucket enforces a minimum retention period for all objects in the bucket, preventing deletion or overwrite until the policy duration has elapsed. Setting it to 5 years ensures that archived log files cannot be deleted before that time, meeting the data engineer's requirement exactly. This is a bucket-level, immutable setting that applies to all objects, unlike object-level holds or lifecycle rules.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Object Lifecycle rule with Delete action after 5 years
Why it's wrong here
Lifecycle rules delete objects, they do not prevent deletion.
- ✓
Retention Policy on the bucket set to 5 years
Why this is correct
Retention policies ensure objects cannot be deleted or replaced until the retention period expires.

- ✗
Object Hold (temporal)
Why it's wrong here

- ✗
Versioning enabled
Why it's wrong here
Versioning keeps multiple versions but does not prevent deletion of the current version.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between lifecycle rules that delete objects and retention policies that prevent deletion, so the trap here is assuming that a lifecycle rule with a Delete action can enforce a retention period, when in fact it does the opposite.
Detailed technical explanation
How to think about this question
Retention policies in Cloud Storage use a bucket-level configuration that sets a `retentionPeriod` in seconds (e.g., 157,800,000 seconds for 5 years). Once set, objects cannot be deleted or overwritten until the retention period expires, and the bucket's `retentionPolicy.locked` field can be set to `true` to make the policy permanent, preventing even the bucket owner from reducing the period. This is critical for compliance with regulations like SEC Rule 17a-4, which requires immutable storage for financial 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 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.
