Question

What three statements are true about LIF failover? (Choose three.)

Options

AA data Ethernet LIF fails over when the cluster is in quorum.
BA cluster management Ethernet LIF fails over when a port is down.
CA cluster management Ethernet LIF will never automatically revert back to its home port.
DA data Ethernet LIF will not revert back by default to its home port.
EA node management Ethernet LIF fails over when a port is down.
FA node management Ethernet LIF will never automatically revert back to its home port.

Explanation

This question tests knowledge of automatic failover triggers and auto-revert defaults for different LIF types in ONTAP.

Common mistakes.

B. Cluster management Ethernet LIFs do not automatically fail over when a port goes down; they require manual migration by an administrator.
C. Cluster management LIFs have auto-revert enabled by default, meaning they will automatically return to their home port once it is restored - making the claim that they 'never' automatically revert factually incorrect.
E. Node management Ethernet LIFs do not trigger automatic failover when a port goes down; like cluster management LIFs, they require manual intervention for migration.
