You need a Cloud Storage lifecycle policy to retain one year of data while minimizing storage cost. Which lifecycle actions should you configure? (Choose the two-step rule that meets this goal.)

This option correctly implements a cost-effective lifecycle for data retention. Initially, data is stored in STANDARD storage for 30 days, suitable for frequently accessed data. After 30 days, it transitions to COLDLINE storage, which is cheaper for data accessed less than once a month, aligning with the goal of minimizing cost for data that needs to be retained but not frequently accessed. Finally, after 365 days (one year), the objects are deleted from COLDLINE, fulfilling the retention requirement. The other options are incorrect because they either use inappropriate storage classes for cost optimization (e.g., transitioning to NEARLINE for long-term retention when COLDLINE or ARCHIVE would be cheaper), have illogical transitions (e.g., COLDLINE to NEARLINE), or delete from the wrong storage class at the end of the retention period.
