Which statement is true about NFS exports in Data ONTAP Cluster-Mode?
The correct answer is C. Export policies and rules are stored in the RDB. In Data ONTAP Cluster-Mode, NFS export policies and rules are stored in the Replicated Database (RDB), replacing the flat-file /etc/exports model used in 7-Mode.

Why each option
In Data ONTAP Cluster-Mode, NFS export policies and rules are stored in the Replicated Database (RDB), replacing the flat-file /etc/exports model used in 7-Mode.
Editing /etc/exports is specific to 7-Mode; Cluster-Mode does not use this file and export policies must be created and modified through the ONTAP CLI or System Manager instead.
Cluster-Mode does not support temporary exports - all export policies are persistent objects stored in the RDB, unlike 7-Mode which allowed temporary export entries.
The RDB is a distributed configuration database built into ONTAP Cluster-Mode that automatically replicates data across all cluster nodes, ensuring every node enforces the same export policies without manual synchronization. Storing export policies in the RDB allows them to be managed centrally via CLI or System Manager and makes them immediately consistent cluster-wide. This is a fundamental architectural departure from the per-node /etc/exports file used in 7-Mode.
Both A and B are individually incorrect, so their combination is also incorrect.
Although C is correct, B is false because temporary exports are not supported in Cluster-Mode, making this combined choice incorrect.
