Operators notice incomplete multipart uploads filling an S3 bucket and also want year-old log objects moved to Glacier automatically. Which S3 feature automates those transitions and expirations?
Select an answer to reveal the explanation.
Short Explanation
Lifecycle rules are the janitor and the mover in one: expire abandoned multipart uploads, shift old logs to Glacier classes, tidy the bucket on a schedule. You write the policy; S3 enforces the transitions and expirations automatically.
Full Explanation
S3 lifecycle rules can expire incomplete multipart uploads and transition or expire objects based on age, prefix, or tags—including moves into Glacier storage classes for older logs. This automation reduces manual cleanup and storage cost. Security Hub, load balancer stickiness, and WAF rate limiting do not implement S3 object lifecycle transitions.
