NS0-157 · Question #159

Which logical interface does not have migration nor failover migration capabilities?

The correct answer is D. target. iSCSI target LIFs do not support migration or failover because iSCSI is a stateful protocol and active sessions are bound to a specific LIF IP address.

Why each option

iSCSI target LIFs do not support migration or failover because iSCSI is a stateful protocol and active sessions are bound to a specific LIF IP address.

Acluster management

Cluster management LIFs support migration to other nodes to maintain administrative access to the cluster during maintenance or failure events.

Bnode management

Node management LIFs support failover to alternative ports on the same node to preserve administrative access when a network port fails.

Cdata

Data LIFs fully support both migration and failover, allowing NAS client access to continue across port failures or planned node maintenance.

DtargetCorrect

Target (iSCSI target) LIFs cannot be migrated or failed over because established iSCSI sessions are tied to the specific IP address of the target LIF - moving the LIF would immediately break all active sessions with no automatic reconnection.
