NS0-158 · Question #23

Which LIF role type is used by a volume move operation between nodes?

The correct answer is B. cluster. A volume move operation between nodes within a NetApp ONTAP cluster requires internal communication and coordination. The cluster Logical Interface (LIF) role is specifically designed to facilitate this intra-cluster node-to-node traffic.

Why each option

A volume move operation between nodes within a NetApp ONTAP cluster requires internal communication and coordination. The `cluster` Logical Interface (LIF) role is specifically designed to facilitate this intra-cluster node-to-node traffic.

Adata

`data` LIFs are used for client access to data volumes (e.g., NFS, SMB, iSCSI) and are not primarily used for internal node-to-node operations like a volume move.

BclusterCorrect

The `cluster` LIF role is specifically designed for internal communication between nodes within the same ONTAP cluster. A volume move operation, which relocates a volume from one node to another node in the cluster, relies on these internal cluster LIFs for control plane and data path synchronization during the transfer, ensuring proper coordination and data integrity.

Cintercluster

`intercluster` LIFs are used for communication between different ONTAP clusters, such as for SnapMirror or SnapVault relationships, not for operations within a single cluster.

Dcluster-mgmt

`cluster-mgmt` LIFs are used for administrative access to the cluster (e.g., using NetApp System Manager, CLI via SSH, or API), and not for the underlying data movement or synchronization of a volume move.
