NS0-157 · Question #117
What are four characteristics of a NAS LIF? (Choose four.)
The correct answer is A. It has a logical interface connection. D. It can be associated with an Ethernet port. E. It can be associated with an interface group (ifgrp) F. It can be associated with an IP address. NAS LIFs are IP-based logical interfaces tied to Ethernet infrastructure and cannot use Fibre Channel components, which are reserved for SAN LIFs.

Why each option
NAS LIFs are IP-based logical interfaces tied to Ethernet infrastructure and cannot use Fibre Channel components, which are reserved for SAN LIFs.
A LIF is by definition a logical interface - a network access point with its own identity that is independent of the underlying physical port.
Fibre Channel ports are used exclusively for SAN LIFs carrying FC or FCoE block-storage traffic, not for IP-based NAS protocols.
A WWPN (World Wide Port Name) is a Fibre Channel SAN identifier assigned to FC LIFs only and has no relevance to IP-based NAS LIFs.
NAS protocols (NFS and SMB/CIFS) operate over TCP/IP, so a NAS LIF must be associated with an Ethernet port to carry IP-based traffic.
An interface group (ifgrp) is a logical aggregation of Ethernet ports, and a NAS LIF can be hosted on an ifgrp the same way it can be hosted on a single Ethernet port.
NAS LIFs require an IP address because NFS and CIFS/SMB are IP-based protocols that clients connect to by IP address or DNS hostname.
