A company stores user uploads in an S3 bucket. Objects are accessed rarely after upload, but when an object is accessed, it must be retrievable quickly (minutes to a few hours). Objects must be retained for at least 18 months. The team wants to reduce storage cost while meeting these requirements. Which lifecycle configuration best fits these requirements?

Keep all objects in S3 Standard permanently to avoid lifecycle transition fees.

Keeping objects in S3 Standard does not reduce storage cost. Lifecycle transitions are specifically designed to move infrequently accessed data to lower-cost storage classes after a delay. Even if there are per-transition request costs, the ongoing savings from using a cheaper storage class for the long retention period typically outweigh those transition request costs.

After 30 days, transition objects to S3 Intelligent-Tiering, and set expiration to 12 months.

Intelligent-Tiering can reduce cost when access patterns are unpredictable, but the expiration setting must still meet the business retention requirement. Expiring at 12 months violates the requirement to retain objects for at least 18 months, so this option would fail compliance.

After 30 days, transition objects to S3 Glacier Deep Archive, and set expiration to 18 months.

Deep Archive is generally the lowest-cost option for data that is extremely rarely accessed, but it has much slower restore times compared with Instant Retrieval. Because the prompt states that when accessed, objects must be retrievable quickly (minutes to a few hours), Deep Archive is not the best fit even though it would satisfy the 18-month retention requirement and would reduce cost.

What does this SAA-C03 question test?

Read the scenario before looking for a memorised answer.

What is the correct answer to this question?

The correct answer is: After 30 days, transition objects to S3 Glacier Instant Retrieval, and after 18 months, expire (delete) the objects. — S3 lifecycle policies can both lower storage cost and enforce retention. Since objects become infrequently accessed but must be retrievable quickly when needed, S3 Glacier Instant Retrieval is the most appropriate storage class. Transitioning after a short period (30 days) reduces ongoing storage spend on the bulk of objects, and expiring after 18 months meets the “retain for at least 18 months” requirement. The other choices either don’t reduce cost (A), delete too early (C), or use a storage class with slower restore times that conflicts with the quick-retrieval requirement (D). A keeps objects in the most expensive class instead of using lifecycle transitions. C violates the explicit 18-month minimum retention by expiring at 12 months. D satisfies retention but conflicts with the stated need for quick retrieval because Deep Archive restores are not intended for minute-to-hour retrieval scenarios.
