Answers
D.
Turn on S3 Object Lock with compliance retention mode for the S3 bucket. Set the retention period to expire after 7 years. Use S3 Batch Operations to bring the existing data into compliance
Suggested answer: C

Explanation:

S3 Object Lock enables a write-once-read-many (WORM) model for objects stored in Amazon S3. It can help prevent objects from being deleted or overwritten for a fixed amount of time or indefinitely1. S3 Object Lock has two retention modes: governance mode and compliance mode. Compliance mode provides the highest level of protection and prevents any user, including the root user, from deleting or modifying an object version until the retention period expires. To use S3 Object Lock, a new bucket with Object Lock enabled must be created, and a default retention period can be optionally configured for objects placed in the bucket2. To bring existing objects into compliance, they must be recopied into the bucket with a retention period specified.

Option A is incorrect because S3 Versioning and S3 Lifecycle do not provide WORM protection for objects. Moreover, MFA delete only applies to deleting object versions, not modifying them.

Option B is incorrect because governance mode allows users with special permissions to override or remove the retention settings or delete the object if necessary. This does not meet the legal requirement of retaining all data for 7 years.

Option D is incorrect because S3 Batch Operations cannot be used to apply compliance mode retention periods to existing objects. S3 Batch Operations can only apply governance mode retention periods or legal holds.
