Sample question · Amazon S3

Written for this page

A team stores monthly reports in Amazon S3. Each report is read often in its first 30 days, then about once a month. When someone does open an old report, it must load in milliseconds. Which option meets these needs at the lowest cost?

  1. A. Keep every object in S3 Standard.
  2. B. Add an S3 Lifecycle rule that moves objects to S3 Standard-Infrequent Access after 30 days.Correct answer
  3. C. Add an S3 Lifecycle rule that moves objects to S3 Glacier Deep Archive after 30 days.
  4. D. Copy the reports to an Amazon EBS volume after 30 days.

Why B: S3 Standard-IA keeps millisecond access at a lower storage price for data you read less often. S3 Glacier Deep Archive costs less to store, but restoring an object takes hours.
