Move videos in a Regional Cloud Storage bucket to Coldline after 90 days and delete them one year after creation. How should you implement the lifecycle policy?

The correct approach is to use Cloud Storage Object Lifecycle Management. This feature automates transitions of objects between storage classes and deletion based on predefined conditions. The SetStorageClass action at 90 days correctly moves the videos to Coldline storage. The Delete action at 365 days ensures the videos are deleted one year after creation, fulfilling the requirement. Using gsutil rewrite is incorrect because it's a manual operation for changing an object's storage class or encryption key, not for automating lifecycle policies. It would not automatically delete objects after a set period. The option suggesting a delete action at 275 days is incorrect because the requirement is to delete one year (365 days) after creation, not 275 days after the Coldline transition.
