If the organization wants to save them in a cost effective way, which is the best possible solution?

An organization is generating digital policy files which are required by the admins for verification. Once the files are verified they may not be required in the future unless there is some compliance issue.

If the organization wants to save them in a cost effective way, which is the best possible solution?
A . AWS RRS
B . AWS S3
C . AWS RDS
D . AWS Glacier

Answer: D

Explanation:

Amazon S3 stores objects according to their storage class. There are three major storage classes: Standard, Reduced Redundancy and Glacier. Standard is for AWS S3 and provides very high durability.

However, the costs are a little higher. Reduced redundancy is for less critical files. Glacier is for archival and the files which are accessed infrequently. It is an extremely low-cost storage service that provides secure and durable storage for data archiving and backup.
