Your organization ingests raw IoT sensor files to a multi-region Cloud Storage bucket. Until today, the bucket had an Object Lifecycle Management rule that permanently deleted any object 90 days after its creation date. A new regulatory mandate requires retaining raw data for at least 180 days, so you removed the Delete rule and saved the updated bucket configuration this afternoon. A teammate plans an overnight Dataflow job that relies on 91-day-old objects still being present. What guidance should you give about the probability of those objects being automatically deleted before the job starts?
Files older than 90 days could still be deleted during the next 24 hours because lifecycle rule changes may take that long to propagate.
Deletion stops immediately after you save the updated configuration, so the dataflow job is safe.
Lifecycle deletions can continue for up to seven days in multi-region buckets due to eventual consistency.
Objects will no longer be deleted, but they will be automatically moved to the bucket's default storage class instead.
When you add, modify, or delete an Object Lifecycle Management rule, Cloud Storage does not guarantee immediate enforcement. Documentation states that lifecycle configuration changes can take up to 24 hours to propagate internally. During that window, the previous configuration may still trigger the associated actions-such as deleting objects that already meet the rule's conditions. Therefore, files older than 90 days can still be removed within the next day even though the rule was deleted. The other options are incorrect because propagation is not instantaneous, does not last as long as seven days, and lifecycle deletion does not silently convert into a storage-class transition.
