Free AWS Certified Solutions Architect Associate SAA-C03 Practice Question
A company has a large number of EC2 instances that generate logs on a daily basis. The logs must be preserved securely for a period of 1 year for compliance reasons, with immediate availability for the first 30 days and infrequent access thereafter. Which of the following backup strategies would be the most cost-effective while meeting the company's requirements?
Use Amazon S3 with a lifecycle policy to transition logs to the S3 Standard-Infrequent Access (IA) tier after 30 days and then to Amazon S3 Glacier after 30 more days.
Use Amazon S3 One Zone-Infrequent Access for log storage, without any transition to other storage classes.
Store all the logs directly in Amazon S3 Glacier for the duration of the 1-year period.
Use Amazon EBS snapshots for daily backups, retaining them for the entire year.
