Q1. – (Topic 2) 

With clustered Data ONTAP 8.2 or later, which are valid values for Fractional reserve? 

A. You cannot change the fractional reserve setting In clustered Data ONTAP 8.2 and later 

B. 0, 25, 50, 75, or 100 

C. 0, 50, or 100 

D. 0 or 100 

E. 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, or 100 



Fractional reserve setting can be set only to 0 or 100 

In previous versions of Data ONTAP, you could set the fractional reserve setting for a 

FlexVol volume to any value between 0 and 100, inclusive. Starting with Data ONTAP 8.2, 

the fractional reserve setting can be set only to 0 or 100. 

If you upgrade a system to Data ONTAP 8.2 with volumes whose fractional reserve settings are between 1 and 99, the fractional reserve setting for those volumes is set to 0. Link: 

Q2. – (Topic 1) 

You set up a SnapMirror relationship between two clusters and start the SnapMirror initialization. The transfer starts without error and begins replicating data. Before the initialization completes, a network failure occurs and the transfer fails to finish. Once the network failure is corrected, you attempt to initialize the transfer again, but receive the following error: 

Volume rep_vol01 is restricted 

Which step should you perform before attempting re-initialization? 

A. Change the state of the destination volume to online. 

B. Delete all Snapshot copies on the destination volume. 

C. Change the state of the destination volume to offline. 

D. Delete all data in the destination volume. 


Q3. – (Topic 3) 

How can you prevent a single SnapMirror relationship from utilizing more than the desired bandwidth? 

A. Specify a SnapMirror throttle for the destination mode 

B. Specify a SnapMirror throttle for the whole cluster 

C. Specify a SnapMirror throttle for that relationship 

D. Enable SnapMirror network compression 


Q4. – (Topic 2) 

What are the characteristics of Snapmirror? (choose three) 

A. Provides data protection for disaster recovery 

B. If the source FlexVol volume is lost, clients can restore data from the secondary to primary storage 

C. Can asynchronously copy the source FlexVol volume to a disaster recovery replica 

D. If the source FlexVol volume is lost or destroyed, clients can connect to the mirror image of the source data 

Answer: A,C,D 

Q5. – (Topic 1) 

Which three disk shelf types are supported in clustered Data ONTAP 8.3? (Choose three.)

B. DS14-MK4-FC 

C. DS14-MK2-FC 

D. DS14-MK2-AT 

E. DS14 

Answer: A,B,D 


Disk shelves supported DS2246 (2U; 24 drives, 2.5" SFF).DS4246 (4U; 24 drives, 3.5" LFF).DS4486 (4U; 48 drives, 3.5" LFF).DS4243 (4U; 24 drives, 3.5" LFF) supported for upgrades only.DS14 disk shelves (mk2-AT, mk4) are supported for upgrades only.

Q6. – (Topic 2) 

Which of the following steps must be completed before a CIFS share can be active? 

A. Configure name mapping 

B. License both NFS and CIFS 

C. Create a data LIF for the CIFS server on every node 

D. Reboot the node containing the CIFS Vserver root volume 


Q7. – (Topic 1) 

You notice your indirect I/O performance between nodes in your 4-node cluster is slowing down from prior week. Each node has two 10 GB connections to the cluster interconnect, one to each switch. You are using four out of 12 available ports on each cluster interconnect switch. Your cluster network utilization is over 80%. 

What should you do to increase cluster interconnect performance? 

A. Change the SFP+ from 10 Gb to 16 Gb on each node and switch. 

B. Add two more cluster interconnect connections per node. 

C. Add additional ISLs between the two cluster interconnect switches. 

D. Change the cable from TwinAx to optical with SFP+ for better throughput. 


Q8. – (Topic 3) 

A clustered Data ONTAP 8.2 Infinite Volume can share an aggregate with an FlexVol volume. 

A. True 

B. False 


Q9. – (Topic 2) 

One node of a 2-node cluster is shut down to replace a NIC. All RDB rings fall out of quorum. To diagnose the problem, what should the administrator do first? 

A. Disconnect and reconnect the InfiniBand cable 

B. Issue storage failover show from the clustershell 

C. Issue cluster ha show from the clustershell 

D. Verify that the cluster switch is functioning properly
