What is the MOST automated and cost-effective way to manage these files?
Answer options:
Write a Cloud Function that runs daily, checks the age of each file, and uses the gsutil command to move older files to a Coldline bucket.
Configure an Object Lifecycle Management policy on the bucket to transition objects to Coldline storage after 30 days, and delete them after 365 days.
Manually change the storage class of the bucket to Coldline at the end of every month.
Use Cloud Scheduler to trigger a Dataflow job monthly to compress and move the logs to Archive storage.
