NS0-157 Question #77: Real Exam Question with Answer & Explanation
The correct answer is B: The LIFs failover-group configuration.. When a CIFS LIF fails to migrate after a switch failure, the LIF failover-group configuration and the ports assigned to the broadcast domain determine whether valid failover targets exist on the surviving switch.
Network Configuration and Data Access
Question
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.)
Options
- AThe protocols allowed on the LIFs.
- BThe LIFs failover-group configuration.
- CThe LIFs home port.
- DThe broadcast domain's member ports.
Explanation
When a CIFS LIF fails to migrate after a switch failure, the LIF failover-group configuration and the ports assigned to the broadcast domain determine whether valid failover targets exist on the surviving switch.
Common mistakes.
- A. Protocols allowed on a LIF govern which data protocols it serves, not its ability to migrate to another port during a hardware failure.
- C. A LIF's home port is where it resides under normal conditions, but it is the failover-group - not the home port - that controls which ports are candidates during a failure event.
