Q2. - (Topic 1) 

A NetApp cluster is connected to two network switches for resiliency. One of the network switches loses power. Most LIFs on the cluster automatically recover from the switch failure to and are reachable through the network. One LIF used for CIFS access is not reachable through the network until power is restored to the failed switch. 

Which two areas should be investigated to determine the problem? (Choose two.) 

A. The protocols allowed on the LIFs. 

B. The LIFs failover-group configuration. 

C. The LIFs home port. 

D. The broadcast domain’s member ports. 

Answer: B,D

Q4. - (Topic 1) 

A customer creates four broadcast domains with the following ports included for node cl-01: bcast1 – e0c 

bcast2 – e0d
