You have an S3 bucket that has enabled versioning. The S3 bucket is used to store testing files. In order to reduce costs, you need to configure S3 lifecycle policies to transit both current and previous versions of objects from standard to One Zone-IA after 60 days. How would you configure it?

Answer options:

A.Configure an S3 lifecycle rule action to change the storage class after 60 days. S3 will transit all the versions of objects automatically.
B.Configure a lifecycle rule action to expire current versions of objects after 60 days. Configure another lifecycle rule action to change the storage class for the previous versions of objects.
C.Configure a lifecycle rule action to transit current versions of objects after 60 days. Configure another lifecycle rule action for the previous versions of objects after 60 days.
D.S3 lifecycle policies cannot transit previous versions of objects for a versioning enabled S3 bucket.

Correct Answer: C
Option A is incorrect because S3 does not transit all the versions of objects automatically. Users need to decide whether to transit current versions or previous versions.
Option B is incorrect because, with the option, the objects will be deleted with a delete marker after 60 days, which is not as expected.
Option C is CORRECT because users need to add two lifecycle rule actions for the current and previous versions of objects.
Option D is incorrect because S3 lifecycle policies can work with an S3 bucket that has enabled versioning and modify the storage class for the previous versions of objects.
