NS0-157 · Question #296

From the output of the command "network interface show", the logical interface that has a value of "false" under the "Is Home" column signifies it (choose all that apply)

The correct answer is B. Has failed over D. Has been migrated. A LIF showing 'Is Home' = false in the network interface show output means it is currently operating on a port or node other than its configured home location.

Why each option

A LIF showing 'Is Home' = false in the network interface show output means it is currently operating on a port or node other than its configured home location.

AIs disconnected

Disconnection state is reflected in the operational status field, not the 'Is Home' column; 'Is Home' = false only indicates the LIF is not on its home port.

BHas failed overCorrect

A LIF shows 'Is Home' = false when it has failed over to an alternate port or node due to a link failure or node outage, meaning ONTAP automatically relocated it away from its home port.

CIs administratively disabled

Administrative enablement or disablement is tracked by a separate 'Status Admin' field in the output and has no relation to the 'Is Home' value.

DHas been migratedCorrect

A LIF also shows 'Is Home' = false when an administrator has manually migrated it using the 'network interface migrate' command, placing it on a non-home port without a failure event.

EIs currently being migrated to home node

A LIF being migrated back toward its home node would still display 'Is Home' = false during transit, but this transient state is not a primary or distinct meaning of the 'Is Home' column value.
