A company stores customer invoices in Amazon S3. Each invoice is read frequently for the first 30 days, only occasionally over the following year, and after that it is needed only on rare audit requests where a retrieval delay of several hours is acceptable. Invoices must be retained for exactly seven years and then permanently removed to satisfy a data-minimisation policy. The team wants the lowest storage cost achieved entirely through a single S3 Lifecycle configuration, with no application changes. Which two lifecycle actions should the solutions architect include? Select TWO.
- AAdd a transition action moving objects to S3 Glacier Flexible Retrieval after one year, where a multi-hour retrieval is acceptable for rare audits. Correct
- BAdd a transition action moving objects to S3 Standard within the first day to guarantee the lowest cost during the frequent-access window.
- CEnable S3 Intelligent-Tiering with the Deep Archive Access tier and rely on it to delete objects after seven years.
- DAdd a transition action moving objects to S3 One Zone-Infrequent Access after seven years to cut the cost of the final archived copies.
- EAdd an expiration action that deletes objects seven years after creation so the invoices are removed once the retention period ends. Correct
Why A is correct: A timed transition to Glacier Flexible Retrieval matches the rare, delay-tolerant audit access and gives the lowest archival storage rate for the later years.
Why B is wrong: Objects already land in S3 Standard by default, so transitioning to it is a no-op that adds a request charge and saves nothing during the hot window.
Why C is wrong: Intelligent-Tiering is tempting for shifting access but it never deletes objects, so it cannot enforce the mandated seven-year removal the policy requires.
Why D is wrong: A transition timed at seven years is pointless because expiration removes the objects then, and One Zone-IA also drops the multi-AZ durability compliance copies need.
Why E is correct: An expiration action enforces the seven-year retention and the mandated deletion automatically, satisfying the data-minimisation requirement without manual cleanup.
