Which StorageGRID feature enables you to have multiple active information lifecycle management (ILM) policies?

The feature that enables multiple active ILM policies is ILM policy tags. NetApp StorageGRID allows administrators to create multiple ILM policies and associate each policy with a specific policy tag. Tenants can then assign one of those ILM policy tags to an S3 bucket, causing objects in that bucket to be managed by the ILM policy associated with the selected tag. This enables different buckets to receive different data-protection, placement, retention, or performance treatments while those policies remain active simultaneously.

StorageGRID also maintains a Default ILM policy tag. Every grid must have an active policy associated with the Default tag, and that policy governs objects in buckets that do not have another ILM policy tag assigned. NetApp supports up to 10 policy tags per grid.

Option A is too general. Although StorageGRID implements the assignment on an S3 bucket, the enabling construct is specifically the ILM policy tag. Option C, multitenancy, separates tenant resources but does not itself permit multiple active ILM policies. Option D, IAM policy, controls S3 access permissions and authorization rather than ILM placement or retention behavior.

Therefore, B is the correct answer.
