AWS Certified Solutions Architect Associate SAA-C03 Practice Question
An organization needs to store legal documents that will be retained for a minimum of seven years to comply with regulatory requirements. These documents will be accessed only in case of an audit, which is expected to occur infrequently. While the company desires to minimize costs, data integrity and recovery capabilities in the event of data loss are of paramount importance. Which AWS service should the company choose to balance cost with their regulatory and durability needs?
Amazon S3 Glacier Deep Archive is designed specifically for data archiving that requires very infrequent access, which makes it the most cost-effective and durable option for long-term data retention such as legal documents. While Amazon S3 One Zone-Infrequent Access might be a tempting option due to its lower storage cost than standard Amazon S3 classes, it stores data in a single Availability Zone and thus lacks the geographical redundancy which is significant for disaster recovery and regulatory requirements. Amazon EBS and Amazon FSx for Lustre are not designed for archiving; they serve different purposes (block and high-performance computing file storage, respectively) and do not offer the same low-cost benefits for infrequently accessed data.
