What three statements are true about LIF failover? (Choose three.)
A. A node management Ethernet LIF will never automatically revert back to its home port.
B. A node management Ethernet LIF can fail over to its partner node when a port is down.
C. A data Ethernet LIF will not automatically revert back to its home port.
D. A cluster management Ethernet LIF will never automatically revert back to its home port
E. A cluster management Ethernet LIF can fail over when a port is down.
F. A data Ethernet LIF can fail over when the cluster is in quorum.
Answer: B,C,E
Explanation: https://library.netapp.com/ecmdocs/ECMP1401193/html/GUID-6DBD40F8-EA21-42AE-82CF-AEB556BEC783.html
"Scenarios that cause a LIF failover
LIF failover occurs in scenarios such as port failure, network interface failure, or cable failure. LIFs can be associated with failover rules that enable you to reroute the network traffic to other available ports in the cluster.
LIF failover occurs in the following scenarios:
When there is a power failure When automatic revert is enabled on a LIF and that LIF's home port reverts to the
administrative up status The LIF automatically migrates back to the home port. When the port hosting a LIF is in the administrative down status The LIFs move to another port. When a node reboots or falls out of quorum The LIFs on that node fail over to the ports on other nodes. If a node returns to quorum, the
LIFs automatically revert to the ports on the node, provided the ports are the home ports for
the LIF and automatic revert is enabled on the LIF.
For more information about quorum, see the Clustered Data ONTAP System
Administration Guide for Cluster Administrators.
When automatic revert is enabled on a LIF and that LIF's home port reverts to the administrative up status the LIF automatically migrates back to the home port."
Q67. - (Topic 2)
When a pNFS 4.1 client is connected to a LIF on node 2 of an 8 node clustered Data ONTAP pNFS 4.1 Vserver, and the data volume being read is moved to node 1, which statement is true?
A. The client redirects from a LIF on node 2 to a LIF on node 1 if available and continues data access uninterrupted.
B. The client stays connected to a LIF on node 2 and accesses the data on node 1 through the cluster network.
C. DNS records are updated and the client moves access to a LIF on node 1 from DNS referral.
D. When a data volume is moved, only CIFS clients are affected.
Answer: A
