QuestionQ84

Data Store Management

The company keeps a large amount of customer records in Amazon S3. To meet regulatory requirements, it must be able to access newly created customer records immediately during the first 30 days after their creation. The company rarely accesses records more than 30 days old.

The company must cost-optimize its Amazon S3 storage.

Which solution meets these requirements in the MOST cost-effective way?

  • A Apply a lifecycle policy to transition records to S3 Standard Infrequent-Access (S3 Standard-IA) storage after 30 days.
  • B Use S3 Intelligent-Tiering storage.
  • C Transition records to S3 Glacier Deep Archive storage after 30 days.
  • D Use S3 Standard-Infrequent Access (S3 Standard-IA) storage for all customer records.
Explanation

S3 Standard-IA is intended for long-lived data that is accessed infrequently but still requires millisecond access. An S3 Lifecycle rule can transition objects to S3 Standard-IA after 30 days, retaining immediate access during the required initial period and reducing storage cost thereafter. S3 Glacier Deep Archive requires archival retrieval, and S3 Intelligent-Tiering is better suited to unknown or changing access patterns.
