AWS Certified Solutions Architect Associate SAA-C03 Practice Question
A company has an application that generates 50 GB of log files each month, which are analyzed quarterly. The current policy is to keep the logs available in hot storage for the first month after generation for immediate analysis if needed, and then move them to a cheaper storage class for the remainder of the quarter. After the analysis, the logs are archived. Which storage strategy is most cost-effective while fulfilling the company's access pattern requirements?
Use Amazon S3 One Zone-Infrequent Access for the entire duration until quarterly analysis, then move the logs directly to S3 Glacier Deep Archive.
Store the logs on Amazon Elastic Block Store (EBS) volumes for the first month, then shift the data to Amazon EFS until the quarterly analysis is done, later archiving to Amazon S3 Standard.
Use Amazon S3 to initially store the logs, transition to S3 Standard-Infrequent Access after one month, and move to S3 Glacier or S3 Glacier Deep Archive for archival after quarterly analysis.
Keep the logs in Amazon S3 Glacier during the initial month for cost savings, and then move to Amazon S3 for quick analysis, archiving them back to S3 Glacier after analysis.
