https://cloud.google.com/storage/docs/bucket-lock https://cloud.google.com/storage/docs/lifecycle Answer A,D

A is correct because Cloud Storage provides an option to configure a retention lifecycle rule. B is incorrect because it is not a recommended way to implement data retention requirements. C is incorrect because it does not guarantee that objects are not deleted within 7 years after object creation. D is correct because it’s the easiest and recommended way to implement a storage lifecycle policy to move objects from Standard to Archive tier. E is incorrect because you do not require two buckets to store objects on two storage tiers.

option AD

AD is the answer. https://cloud.google.com/storage/docs/bucket-lock This page discusses the Bucket Lock feature, which allows you to configure a data retention policy for a Cloud Storage bucket that governs how long objects in the bucket must be retained. The feature also allows you to lock the data retention policy, permanently preventing the policy from being reduced or removed. https://cloud.google.com/storage/docs/storage-classes#archive Archive storage is the lowest-cost, highly durable storage service for data archiving, online backup, and disaster recovery. Unlike the "coldest" storage services offered by other Cloud providers, your data is available within milliseconds, not hours or days. Archive storage is the best choice for data that you plan to access less than once a year.
