NS0-157 Question #152: Real Exam Question with Answer & Explanation

Question

Options

• Acluster LIF
• Bdata LIF of protocol CIFS
• Cdata LIF of protocol FCoE
• Ddata LIF of protocol iSCSI
• Edata LIF of protocol NFS
• Fintercluster LIF
• Gnode management LIF

Explanation

This question tests which ONTAP LIF types support cross-node failover and migration, distinguishing NAS protocol LIFs from SAN and infrastructure LIFs.

Common mistakes.

• A. Cluster LIFs are dedicated to intra-cluster heartbeat and data replication traffic on the private cluster network and are never migrated or failed over - they must remain on their assigned cluster ports.
• C. FCoE data LIFs are bound to specific Converged Network Adapter (CNA) ports and are part of the FC fabric zoning, making cross-node migration impossible - FCoE relies on host-side multipathing for redundancy.
• D. iSCSI data LIFs do not support cross-node migration because iSCSI sessions are stateful and tied to a specific target IP; redundancy for iSCSI is achieved through host-side MPIO across multiple LIFs, not LIF migration.
• F. Intercluster LIFs are dedicated to SnapMirror replication and cluster peering traffic between separate clusters and do not support intra-cluster failover or migration to other nodes.
• G. Node management LIFs are scoped to their specific node for out-of-band administrative access and can only fail over between ports on the same node - they cannot migrate to a different node in the cluster.

Concept tested. ONTAP LIF cross-node failover and migration by protocol type
