Q106. - (Topic 2) 

What two actions should an administrator take before shutting down two nodes of a 4-node cluster? (Choose two.) 

A. reassign the master of all RDB rings to a node that will be staying up 

B. migrate node-management LIFs to a node that will be staying up

Q107. - (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 

Q108. - (Topic 2)

A. Node 

B. Cluster 

C. Intercluster 

D. Vserver 

Answer: A,D 

Q109. - (Topic 1)

Referring to the exhibit, how many paths to the LUN will the host see? 

A. 32 

B. 16 

C. 8 

D. 4 


94. - (Topic 1) 

Which LIF parameter determines the ports that the LIF moves to when the current interface goes offline? 

A. auto-revert 

B. ipspace 

C. failover-group 

D. netmask 


Explanation: You can revert a LIF to its home port after it fails over or is migrated to a different port either manually or automatically. If the home port of a particular LIF is unavailable, the LIF remains at its current port and is not reverted. alse 

Q110. - (Topic 1) 

A customer wants to use FlashCache but does not want to lose the information stored in the FlashCache card when a takeover occurs in a high-availability solution. 

What should the customer do to make sure this feature is enabled? 

A. Confirm that the aggregates using the FlashCache card are configured appropriately. 

B. Set the option to rewarm the FlashCache in both nodes of the HA pair. 

C. Verify that the FlashCache card is located in the appropriate slot in the NetApp controller. 

D. Verify that the FlashCache card has been configured only on the node where the feature is required. 


Explanation: The system does not serve data from a Flash Cache or Flash Cache 2 module when a node is shutdown. However, the WAFL external cache preserves the cache during a graceful shutdown and can serve "warm" data after giveback. The WAFL external cache can preserve the cache in Flash Cache modules during a graceful shutdown. It preserves the cache through a process called "cache rewarming," which helps to maintain system performance after a graceful shutdown. For example, you might shut down a system to add hardware or upgrade software. Cache rewarming is enabled by default if you have a Flash Cache or Flash Cache 2 module installed. Cache rewarming is available when both nodes in an HA pair are running Data ONTAP 8.1 or later.
