After a storage failover, you notice that a NAS LIF, that is linked to the broadcast domain CIFS, is no longer reachable after the takeover. Node cluster1-01 is still waiting for giveback.

Referring to the exhibit, what caused the problem?

A. Port a0a of node cluster1-01 is down.
B. The LIF has to be configured with a failover group.
C. The ports of cluster1-02 are missing in the broadcast domain.

D. The broadcast-domain MTU needs to be either 1500 or 9000.
