Click the Exhibit button.
You have a 2-node NetApp cluster. You perform a storage failover and notice that IP address 10.1.100.21 is
unreachable while omegana1-01 is rebooting. After omegana1-01 is back online, the IP address becomes
reachable again. However, IP address 10.1.100.20 was still reachable during the reboot. The commands
shown in the exhibit were executed before the storage failover.
In this scenario, why was IP address 10.1.100.21 unreachable?
A.
The LIF for 10.1.100.21 has an incorrect failover setting.
B.
The failover group for 10.1.100.21 is misconfigured.
C.
The node management LIFs cannot fail over to other nodes.
D.
The Address Resolution Protocol (ARP) cache needs to be cleared on the upstream switch.
Explanation:
The purpose and the default behavior of a LIF is indicated by the role associated with that LIF. Each LIF is
assigned a default failover group and failover policy when you create the LIF. These settings automatically
configure the LIF with a list of failover targets from the ports available in the failover group, so you need to
understand the relationship between LIF roles and failover groups.

The failover group includes all ports, but the default policy is set to “local-only”, which means there is no failover for the node management LIF, so answer A makes more sense in my opinion. See: https://library.netapp.com/ecmdocs/ECMP1636021/html/GUID-D99400AB-789A-4F6A-8443-9F74165F2B88.html

agreed… Answer = C.
node mgmt LIF’s can’t be migrated to another node.

hmm are you sure? The default setting is “local-only” but in general it should be possible to configure a node mgmt to failover, see
https://library.netapp.com/ecmdocs/ECMP1196907/html/GUID-DFFBE8D9-E824-4085-8FA2-24E367288CB8.html

But on the other hand all other answers make no sense, so C seems to be the most logical one.

I think A makes more sense, see:
https://library.netapp.com/ecmdocs/ECMP1636021/html/GUID-92CC5F58-5EB8-4E2D-88F0-FA2F740062E0.html
You can change the failover setting for a node mgmgt LIF by using another policy and the “local-only” policy can be exchanged, except for cluster LIFs.
Local-only:
This is the default setting for cluster LIFs and node management LIFs.
This value cannot be changed for cluster LIFs.

I am not sure what the purpose of node management lif failover/migration is. If for example your node is offline for some reason, why would you still want to access this lif?

I’ll go with C. Why if you right click node management interface you will see migrate option disabled which says it cannot be migrated to different.

C for sure
