Which statement is true about NFS export in Cluster-Mode?

The correct answer is C. Export policies and rules are stored in the RDB. In ONTAP Cluster-Mode, NFS export policies and rules are stored persistently in the Replicated Database (RDB), replacing the 7-Mode /etc/exports file model.

Why each option

In ONTAP Cluster-Mode, NFS export policies and rules are stored persistently in the Replicated Database (RDB), replacing the 7-Mode /etc/exports file model.

AExport policies are created and modified by editing /etc/exports.

The /etc/exports file is a 7-Mode construct and does not exist in ONTAP Cluster-Mode; export policies are managed through the CLI or System Manager and persisted in the RDB.

BExports can be either persistent or temporary.

ONTAP Cluster-Mode exports are always persistent because they are stored in the RDB; there is no concept of temporary exports as existed in some legacy NFS implementations.

CExport policies and rules are stored in the RDB.Correct

ONTAP Cluster-Mode stores all export policies and their associated rules in the Replicated Database (RDB), which replicates the configuration across all nodes in the cluster for high availability. This means export policies survive node failures and do not require manual file editing, unlike the 7-Mode /etc/exports approach.

DBoth A and B

Both A and B are false - /etc/exports is not used in Cluster-Mode and temporary exports do not exist, so this combined answer is incorrect.

EBoth B and C

B is false (temporary exports do not exist in Cluster-Mode), so the combination of B and C cannot be the correct answer.
