- A
Cloud Scheduler jobs that run gsutil rewrite and gsutil rm commands nightly
Why wrong: Custom scheduler jobs add operational complexity and are unnecessary — lifecycle rules run automatically without any infrastructure to maintain.
- B
Cloud Storage Object Lifecycle Management rules on the bucket
Lifecycle rules on the bucket automatically transition objects to Coldline after 90 days and delete them after 365 days — fully managed with no scripts or schedulers required.
- C
Cloud Pub/Sub notifications triggering a Cloud Function on each object creation
Why wrong: This approach processes objects at creation time — it can't retroactively apply lifecycle policies to aging objects based on their age.
- D
Retention policies that lock objects in Coldline after 90 days
Why wrong: Retention policies prevent deletion for a minimum period — they're for compliance, not for transitioning between storage classes.
Quick Answer
The answer is Cloud Storage Object Lifecycle Management rules on the bucket. This feature automates Cloud Storage lifecycle tiering deletion by allowing you to define conditional actions based on object age, such as moving logs older than 90 days to Coldline storage and permanently deleting them after 365 days. On the Google Associate Cloud Engineer exam, this question tests your understanding of native, serverless storage management—a key concept because many candidates mistakenly try to use Cloud Functions or cron jobs for scheduled transitions, which adds unnecessary complexity and cost. The correct approach leverages the bucket’s built-in rules, which require no external compute and execute reliably at scale. A common trap is confusing lifecycle rules with Object Versioning or retention policies; remember that lifecycle rules are for automated transitions and deletions, not for locking data. Memory tip: think “age-based automation” for tiering and deletion—if the condition is time, the solution is lifecycle.
Google ACE Practice Question: Ensuring successful operation of a cloud solution
This ACE practice question tests your understanding of ensuring successful operation of a cloud solution. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 team stores application log archives in a Cloud Storage bucket. Logs older than 90 days should automatically move to Coldline storage, and logs older than 365 days should be deleted. Which feature automates this?
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
Cloud Storage Object Lifecycle Management rules on the bucket
Option B is correct because Cloud Storage Object Lifecycle Management rules allow you to automatically transition objects to Coldline storage after 90 days and delete them after 365 days based on object age conditions. This is a native, serverless feature that requires no external compute or scheduling, making it the most efficient and reliable approach for automating tiering and deletion of log archives.
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 misconception that custom scheduling or event-driven functions are required for automated data management, when in fact Cloud Storage's native lifecycle management handles age-based transitions and deletions without any additional services.
Detailed technical explanation
How to think about this question
Under the hood, Cloud Storage Lifecycle Management rules are evaluated asynchronously, typically within 24 hours of the condition being met, and can be applied at the bucket level using JSON or XML configurations. A real-world scenario where this matters is in compliance-driven environments (e.g., HIPAA or SOC 2) where automated data retention and deletion policies must be auditable and cannot rely on custom scripts that might fail or be tampered with.
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.
