Google Cloud Associate Data Practitioner — Question 37

You are responsible for managing Cloud Storage buckets for a research company. Your company has well-defined data tiering and retention rules. You need to optimize storage costs while achieving your data retention needs. What should you do?

Answer options

• A. Configure the buckets to use the Archive storage class.
• B. Configure a lifecycle management policy on each bucket to downgrade the storage class and remove objects based on age.
• C. Configure the buckets to use the Standard storage class and enable Object Versioning.
• D. Configure the buckets to use the Autoclass feature.

Correct answer: B

Explanation

The correct answer is B because configuring a lifecycle management policy allows for automation in managing the storage class and removing outdated objects, which directly aligns with cost optimization and retention needs. Option A is not optimal since Archive storage may not meet all retention needs, while C unnecessarily increases costs with Object Versioning. Option D, while useful, does not provide the same level of control over data lifecycle management as option B.
