    A company has both on-premises data center as well as AWS cloud infrastructure. They store their graphics, audio, videos, and other multimedia assets primarily in their on-premises storage server and use an S3 Standard storage class bucket as a backup. Their data is heavily used for only a week (7 days) but after that period, it will only be infrequently used by their customers. The Solutions Architect is instructed to save storage costs in AWS yet maintain the ability to fetch a subset of their media assets in a matter of minutes for a surprise annual data audit, which will be conducted on their cloud storage.

    Which of the following are valid options that the Solutions Architect can implement to meet the above requirement? (Select TWO.)

    <ul data-stringify-type=”unordered-list” data-list-tree=”true” data-indent=”0″ data-border=”0″>

  • Set a lifecycle policy in the bucket to transition the data from Standard storage class to Glacier after one week (7 days).
  • Set a lifecycle policy in the bucket to transition the data to S3 – Standard IA storage class after one week (7 days).
  • Set a lifecycle policy in the bucket to transition the data to S3 – One Zone-Infrequent Access storage class after one week (7 days).
  • Set a lifecycle policy in the bucket to transition the data to S3 Glacier Deep Archive storage class after one week (7 days).
  • Set a lifecycle policy in the bucket to transition to S3 – Standard IA after 30 days

  • Glacier has a minimum storage duration of 90 days and almost everything else is 30 days. So saying this is correct and to transition after 7 days is incorrect according to AWS https://docs.aws.amazon.com/AmazonS3/latest/userguide/storage-class-intro.html#sc-compare

    Hello asksecurityking,

    Thank you for your feedback.

    You can configure an S3 lifecycle policy to transition objects from S3 Standard to Glacier after as few as 7 days. The 90-day minimum storage duration only affects the cost, not the ability to transition. Objects moved to Glacier that are deleted or moved again before 90 days will incur charges for the remaining days up to 90.

    Take note that the explanation specifically states that changing the storage class of your objects from S3 Standard to STANDARD_IA or ONEZONE_IA is only allowed after 30 days. However, this limitation does NOT apply to INTELLIGENT_TIERING, GLACIER, and DEEP_ARCHIVE storage classes.

    Please refer to this screencast.

    Hope this helps!

    Regards,
    JR @ Tutorials Dojo

    thanks for clarifying this – I was confused with this limitation between storage classes as well
