NS0-157 · Question #300

Which types of LIFs can be assigned a user-defined failover group? (choose all that apply)

The correct answer is B. Node-management LIF C. Cluster-management LIF D. NAS data LIF (NFS,CIFS). Node management, cluster management, and NAS data LIFs can be assigned user-defined failover groups, while cluster LIFs are restricted to system-defined groups and SAN LIFs do not support LIF-level failover.

Why each option

Node management, cluster management, and NAS data LIFs can be assigned user-defined failover groups, while cluster LIFs are restricted to system-defined groups and SAN LIFs do not support LIF-level failover.

ACluster LIF

Cluster LIFs are restricted to system-defined failover groups bound to the cluster interconnect broadcast domain and cannot be assigned user-defined failover groups.

BNode-management LIFCorrect

Node management LIFs support user-defined failover groups, allowing administrators to restrict which ports the management interface may use during a failover event. This provides control over management reachability across specific network segments.

CCluster-management LIFCorrect

Cluster management LIFs support user-defined failover groups so administrators can define exactly which ports the cluster-wide management IP can migrate to, ensuring it remains accessible on a controlled subset of interfaces.

DNAS data LIF (NFS,CIFS)Correct

NAS data LIFs for NFS and CIFS fully support user-defined failover groups, enabling administrators to scope failover to specific ports or subnets and avoid unintended migration to ports on different network segments.

ESAN data LIF (iSCSI, FC)

SAN data LIFs for iSCSI and FC do not support LIF failover in ONTAP; host-side multipathing technologies such as MPIO for iSCSI and NPIV-based zoning for FC provide redundancy at the initiator level instead.
