Which of the following statements are true about SAN LIFs? (choose all that apply)

The correct answer is A. SAN LIFs are either up or down E. NAS and SAN LIFs can share the same data port. SAN LIFs in NetApp ONTAP have a simple binary up/down state with no failover or migration, but multiple LIFs of different protocol types can share the same physical data port.

Why each option

SAN LIFs in NetApp ONTAP have a simple binary up/down state with no failover or migration, but multiple LIFs of different protocol types can share the same physical data port.

ASAN LIFs are either up or downCorrect

SAN LIFs (FC and iSCSI) operate in only an up or down state - unlike NAS LIFs, they have no migration or partial-active state, and SAN redundancy is handled entirely by host-side multipath I/O (MPIO).

BNAS and SAN protocols can share the same LIF

NAS and SAN protocols cannot share the same LIF - each LIF is configured for a specific protocol type (NFS/CIFS or FC/iSCSI) and cannot carry both simultaneously.

CSAN LIFS can migrate or failover

SAN LIFs do not support migration or failover - because SAN hosts use persistent WWPN/IQN bindings, moving a LIF would break those connections, so host-side MPIO handles redundancy instead.

DSAN LIFs can be associated with more than one data vserver

Each SAN LIF belongs to exactly one data SVM (vserver) and cannot be associated with or shared across multiple data SVMs.

ENAS and SAN LIFs can share the same data portCorrect

A single physical data port can host both NAS and SAN LIFs simultaneously, as ONTAP allows multiple LIFs of different protocol types to be bound to the same underlying port.
