AWS Certified Solutions Architect Associate SAA-C03 Practice Question
A company stores large datasets of their completed projects in an Amazon S3 bucket. This data is rarely accessed but must be preserved for regulatory compliance. The datasets must be retrievable within a few hours if accessed. Which storage class should the Solutions Architect recommend to optimize costs while meeting the data retrieval requirements?
Amazon S3 Glacier Flexible Retrieval (previously known as Amazon S3 Glacier) is the most cost-effective storage class for data that is accessed infrequently and can tolerate retrieval times in the range of several minutes to hours. Amazon S3 Intelligent-Tiering is not the most cost-effective for this use case as it is meant for data with unknown access patterns. Amazon S3 Standard is not cost-optimized for rarely accessed data. Amazon S3 One Zone-Infrequent Access is also not appropriate as it is designed for infrequently accessed data but with a retrieval time similar to the Standard class.
