NS0-157 · Question #179

What must be define in order to create a NFS export within Cluster-Mode?

The correct answer is B. An export policy and rules under a Vserver. In ONTAP Cluster-Mode, NFS access is controlled through export policies and rules that are defined and applied within the scope of a Vserver (SVM), replacing the flat /etc/exports file model.

Why each option

In ONTAP Cluster-Mode, NFS access is controlled through export policies and rules that are defined and applied within the scope of a Vserver (SVM), replacing the flat /etc/exports file model.

AAn entry in the /etc/exports file

The /etc/exports file is a legacy UNIX and NetApp 7-Mode mechanism and is not used in ONTAP Cluster-Mode NFS configuration.

BAn export policy and rules under a VserverCorrect

ONTAP Cluster-Mode uses a policy-based export model where an export policy contains one or more rules specifying client match criteria and access permissions. These policies are created and managed within a Vserver (Storage Virtual Machine) and are applied directly to volumes or qtrees to grant NFS access.

CAn export policy and rules under the FreeBSD shell

The FreeBSD shell (nodeshell) does not manage NFS exports in Cluster-Mode - export configuration is handled at the Vserver level through the ONTAP CLI or System Manager.

DAn export policy and rules under the node shell

The node shell is a low-level diagnostic interface in ONTAP and is not the correct context for creating or managing NFS export policies.

Eexport rules that are associated with a LIF

Export rules must be contained within an export policy that is associated with a Vserver and applied to a volume - rules cannot stand alone attached only to a LIF.
