DEA-C01 Data Store Management Practice Question
A company has an Amazon S3 bucket with versioning enabled. They want to automatically delete noncurrent versions of objects after 30 days. Which lifecycle rule action should be used?
⚠ Common exam trap
A common mix-up: candidates confuse NoncurrentVersionExpiration with Expiration, as candidates often mistakenly apply the standard Expiration action to delete old versions, not realizing it only affects the current version.

Correct answer & explanation
✓
NoncurrentVersionExpiration
The NoncurrentVersionExpiration lifecycle action is specifically designed to remove noncurrent object versions after a specified number of days. Since versioning is enabled and the requirement is to delete noncurrent versions after 30 days, this action directly meets the goal without affecting current versions or other lifecycle aspects.
