NS0-157 · Question #160

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

The correct answer is B. cluster management C. data. Cluster management and data LIFs support both failover and migration in ONTAP, ensuring continuous administrative and client access during network events.

Why each option

Cluster management and data LIFs support both failover and migration in ONTAP, ensuring continuous administrative and client access during network events.

Aclient

'Client' is not a defined LIF role in ONTAP; valid roles are data, cluster management, node management, cluster, and intercluster.

Bcluster managementCorrect

Cluster management LIFs support both failover and migration, allowing uninterrupted cluster-wide administrative access even when individual ports or nodes fail.

CdataCorrect

Data LIFs support full failover and migration across ports and nodes, preserving NAS client connections during failures or planned maintenance operations.

Dnode management

Node management LIFs support only limited port-level failover on the same node and do not support migration to other nodes, so they do not meet both criteria.

Econtroller

'Controller' is not a valid ONTAP LIF role; this term does not correspond to any defined logical interface type in ONTAP networking.
