NS0-157 Question #347: Real Exam Question with Answer & Explanation

The correct answer is A: SAN LIFs are either up or down. 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.

Question

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

Options

ASAN LIFs are either up or down
BNAS and SAN protocols can share the same LIF
CSAN LIFS can migrate or failover
DSAN LIFs can be associated with more than one data vserver
ENAS and SAN LIFs can share the same data port

Explanation

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.

Common mistakes.

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