Which statement is true about CFO and SFO in clustered ONTAP?

CFO (Controller Failover) aggregates include the root aggregate, which holds the node's boot volume and system configuration; these must be returned first to bring the node fully operational. Once the root is restored, SFO (Storage Failover) aggregates are given back sequentially, one at a time, to allow volumes to come online in an orderly and stable manner.

SFO aggregates are not returned before CFO aggregates; the root aggregate contained in the CFO aggregate must be handed back first to establish the node's identity before data aggregates are relinquished.

Giveback is a staged, sequential process - not simultaneous - to prevent resource conflicts and ensure each aggregate and its volumes come online safely.

Clustered ONTAP supports both CFO and SFO aggregate types; CFO aggregates, particularly the root aggregate, are a fundamental component of each node's HA configuration.
