Explanation:
The correct answer is D because the Nearline storage class is cost-effective for data accessed about once a month, and moving older data to Coldline is ideal for archival purposes, complying with the 5-year retention requirement. Multi-Regional storage is not cost-efficient for infrequent access (making options A and B incorrect), and deleting data older than 5 years violates compliance needs (making option C incorrect). For more details, refer to the GCP documentation on Cloud Storage – Storage Classes.

To optimize costs for infrequently accessed data that needs to be refreshed monthly for historical charts and archived for 5 years for compliance, what is the best storage and management strategy in Google Cloud?
A
Store in Google Cloud Storage using a Multi-Regional bucket with an Object Lifecycle Management policy to delete data older than 5 years.
B
Store in Google Cloud Storage using a Multi-Regional bucket with an Object Lifecycle Management policy to change the storage class to Coldline for data older than 5 years.
C
Store in Google Cloud Storage using a Nearline bucket with an Object Lifecycle Management policy to delete data older than 5 years.
D
Store in Google Cloud Storage using a Nearline bucket with an Object Lifecycle Management policy to change the storage class to Coldline for data older than 5 years.
