When creating a LIF for NFS or CIFS, what is the default failover policy?
The correct answer is B. Nextavail. The default LIF failover policy for NFS and CIFS data LIFs in ONTAP is 'nextavail', which moves the LIF to the next available port in the failover group when its home port fails.

Why each option
The default LIF failover policy for NFS and CIFS data LIFs in ONTAP is 'nextavail', which moves the LIF to the next available port in the failover group when its home port fails.
The 'priority' failover policy selects the highest-priority available port from the failover group, but this is not the default policy assigned to NFS or CIFS LIFs in ONTAP.
ONTAP automatically assigns the 'nextavail' failover policy to file-services LIFs (NFS and CIFS) by default. This policy selects the next available port on the failover target list in order, ensuring the LIF migrates quickly and predictably to maintain client connectivity without requiring administrator-defined port priorities.
Round-robin is not a valid ONTAP LIF failover policy; supported policies include nextavail, priority, broadcast-domain-wide, and disabled, among others.
The 'disabled' policy prevents any LIF failover, which contradicts the default design goal of maintaining high availability for file-services traffic when a port or node fails.
