An autonomous vehicle testing company uploads high-resolution LiDAR and sensor log files to a Google Cloud Storage bucket. The uploaded data is analyzed and queried daily by machine learning training pipelines during the first 30 days. After 30 days, the files are rarely accessed (less than once per year) for compliance verification, but regulatory policies require them to be retained for a total of 3 years before deletion. You need to design an Object Lifecycle Management policy to minimize total storage and operational costs while avoiding early deletion fee penalties. Which TWO lifecycle rules should you include in the bucket configuration? (Select TWO.)
- Transition objects to Archive storage class when their age reaches 30 days.Answer
- Delete objects when their age reaches 1,095 days.Answer
- CSet the default bucket storage class to Archive upon initial upload.
- DTransition objects to Coldline storage class when their age reaches 1,095 days prior to deletion.
Answer
The optimal lifecycle strategy involves transitioning objects to the Archive storage class after 30 days of active use and configuring an object deletion rule after 1,095 days (3 years).
Data active during the first 30 days benefits from Standard storage. Transitioning to Archive storage at 30 days optimizes storage costs for data accessed less than once a year during the remainder of its 3-year life. Deleting the objects at 1,095 days ensures regulatory compliance without paying for unnecessary long-term storage.
