- A
Enable Object Versioning on the bucket.
Why wrong: Versioning keeps deleted objects as noncurrent, but not the same as retention policy.
- B
Set the bucket's default event-based hold.
Why wrong: Event-based hold is different; it applies per-object, not a blanket retention.
- C
Lock the retention policy using gsutil retention lock gs://my-bucket.
Locking makes the policy permanent.
- D
Set an IAM policy to prevent deletion.
Why wrong: IAM can prevent deletion of the bucket, but not objects within.
- E
Set a retention policy using gsutil retention set 30d gs://my-bucket.
Sets retention period to 30 days.

Google ACE Deploying and Implementing a Cloud Solution Practice Question
This ACE practice question tests your understanding of deploying and implementing a cloud solution. 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.
You need to create a Cloud Storage bucket with a retention policy that prevents object deletion for 30 days. Which TWO steps are necessary?

Correct answer & explanation
✓
Lock the retention policy using gsutil retention lock gs://my-bucket.
To enforce a retention policy that prevents object deletion for 30 days, you must first set the retention policy using `gsutil retention set 30d gs://my-bucket`. However, setting the policy alone is not sufficient because it can be removed or changed. To make the policy permanent and unchangeable, you must lock it using `gsutil retention lock gs://my-bucket`. Step C is necessary to lock the policy, and step E is necessary to set the duration. Enabling object versioning (A) does not prevent deletion; it only retains previous versions. Setting a default event-based hold (B) is for indefinite holds triggered by events, not a fixed duration. IAM policies (D) control who can delete, but do not prevent deletion outright.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
