NS0-157 · Question #345

Which of the following logical interfaces have failover and migration capabilities between nodes? (choose all that apply)

The correct answer is B. Cluster management C. Data (CIFS, NFS). In NetApp ONTAP, only NAS data LIFs (CIFS/NFS) and the cluster management LIF support failover and migration between nodes.

Why each option

In NetApp ONTAP, only NAS data LIFs (CIFS/NFS) and the cluster management LIF support failover and migration between nodes.

AData (FC, iSCSI)

SAN LIFs using FC or iSCSI protocols do not support LIF migration or failover between nodes - they rely on host-side multipathing (MPIO/ALUA) for redundancy instead.

BCluster managementCorrect

The cluster management LIF provides administrative access to the entire cluster and supports automatic failover to another node if the hosting node becomes unavailable, ensuring continuous management access to the cluster.

CData (CIFS, NFS)Correct

NAS data LIFs using CIFS or NFS protocols are specifically designed to support both manual LIF migration and automatic failover between nodes, enabling non-disruptive operations for file-sharing clients.

DNode management

Node management LIFs are dedicated to managing a specific node and are bound to that node - they do not migrate or fail over to other nodes in the cluster.

ECluster interconnect

Cluster interconnect LIFs handle intra-cluster communication and are fixed to dedicated interconnect ports - they do not support migration or failover.
