Which StorageGRID feature enables a compliant ILM policy to prevent object deletion?

• A. S3 Object Lock
• B. Cloud Storage Pool
• C. SnapLock Compliance
• D. S3 bucket access policy

Answer: (A)

Immutability and retention to meet regulatory requirements is what this is testing. S3 Object Lock in StorageGRID provides retention and locking on objects stored via the S3 API, so they cannot be deleted or altered during the defined period. With a Compliance retention mode, no one—not even administrators—can delete the object until the retention period expires, which directly supports a compliant ILM policy. This makes the data effectively immutable for the required duration, aligning object lifecycle rules with regulatory needs.

The other options don’t enforce this level of retention. Cloud Storage Pool is just a storage tier/configuration, not a retention lock. SnapLock Compliance is a WORM feature that also enforces immutability, but the question specifically points to the S3 API mechanism for enforcing deletion prevention in an ILM policy. S3 bucket access policy controls who can delete, but it does not enforce retention or immutability itself.
