  The maximum RAID group size of the RAID-DP aggr1 shown in the exhibit is 18. You expand the aggregate by 20 disks. How many of the new disks are used for data?

  A. 20
  B. 16
  C. 14
  D. 18

  RAID 6 extends RAID 5 by adding another parity block; thus, it uses block-level striping with two parity blocks distributed across all member disks. Figure: Diagram of a RAID 6 setup, which is identical to RAID 5 other than the addition of a second parity block

  

• Question 23:

  You are creating the source and destination SVMs for a new SVM disaster recovery relationship. Which SVM set of subtypes should you choose?

  A. Source SVM default, Destination SVM: default
  B. Source SVM default, Destination SVM: dp-destination
  C. Source SVM default, Destination SVM: sync-dest
  D. Source SVM default, Destination SVM: sync-dest
  B. Source SVM default, Destination SVM: dp-destination

  ---

  A destination Storage Virtual Machine (SVM) is an SVM with the dp-destination subtype created for protecting a source SVM that serves data. A destination SVM contains replicated data and configuration of the source SVM. References: https://library.netapp.com/ecmdocs/ECMP12454817/html/GUID-62D54AB4- BAE3-49A9-8F43-98DC03BC4602.html

• Question 24:

  Click the Exhibit button.

  

  An administrator installed UTA2 PCIe cards into an existing FAS8200 HA pair. The new cards will be used for native FC traffic. The administrator wants to configure the UTA2 ports for FC client access. Referring to the exhibit, which two actions address the requirement? (Choose two.)

  A. Use the network fcp adapter modify command to bring the adapter online.
  B. Reboot the node to bring the adapter online after final configuration.
  C. Use the system hardware unified-connect command to verify that the port mode is set to initiator.
  D. Use the ucadmin modify command to set the adapter mode to FC.
  B. Reboot the node to bring the adapter online after final configuration.
  D. Use the ucadmin modify command to set the adapter mode to FC.

  ---

  B: Ports must be converted in pairs, for example, 0c and 0d, after which, a reboot is required, and the ports must be brought back to the up state.

  D: CNA ports can be configured into native Fibre Channel (FC) mode or CNA mode.

  If the current configuration does not match the desired use (here we want to change from CNA mode to FC mode), enter the following commands to change the configuration as needed:

  system node hardware unified-connect modify -node node_name -adapter adapter_name - mode fc|cna -type target|initiator

  -mode is the personality type, fc or 10GbE cna.

  -type is the FC4 type, target or initiator.

• Question 25:

  An administrator enabled the iSCSI protocol on an SVM and created a LUN for a Windows 2016 system. After rescan, the LUN is not visible on the host. Which two steps must the administrator take to solve this problem? (Choose two.)

  A. Create an initiator group (igroup), add the WWPN of the host initiator, and then map the igroup to the LUN.
  B. Disable the ALUA support from the host for the LUN.
  C. Configure the iSCSI service on the Windows 2016 system.
  D. Create an initiator group (igroup), add the iSCSI IQN, and map the igroup to the LUN.
  C. Configure the iSCSI service on the Windows 2016 system.
  D. Create an initiator group (igroup), add the iSCSI IQN, and map the igroup to the LUN.

  ---

  D: An iSCSI qualified name (IQN) identifier is a worldwide unique name that each iSCSI initiator and iSCSI target must have. The IQN for an iSCSI initiator is available in Microsoft iSCSI Software Initiator or other iSCSI initiators. Typically the IQN is used by the iSCSI target to identify the iSCSI initiator.

• Question 26:

  Click the Exhibit button.

  

  The size of the aggr1 RAID group shown in the exhibit is 8. What is the RAID type?

  A. RAID-TEC
  B. RAID-DP
  C. RAID4
  D. RAID0
  B. RAID-DP

  RAID 6 extends RAID 5 by adding another parity block; thus, it uses block-level striping with two parity blocks distributed across all member disks. Figure: Diagram of a RAID 6 setup, which is identical to RAID 5 other than the addition of a second parity block

  

• Question 27:

  You need to duplicate a production LUN for quality assurance testing. The LUN resides in svm_prod and needs to be available in svm_qa. Both SVMs reside on the same cluster. Which step will accomplish this task?

  A. Issue the lun move command.
  B. Issue the volume rehost command.
  C. Issue the lun copy command.
  D. Issue the volume move command.
  C. Issue the lun copy command.

  ---

  Cluster administrators can copy a LUN across Storage Virtual Machines (SVMs) within the cluster by using the lun copy command.

• Question 28:

  Which CLI command is used to move epsilon to a new node?

  A. cluster modify
  B. cluster identity modify
  C. cluster setup
  D. storage failover takeover
  A. cluster modify

  ---

  Reassigning epsilon to another node in the cluster. Only one node in the cluster can hold epsilon. Epsilon gives the holding node an extra fractional voting weight in the quorum. Steps References: https://library.netapp.com/ecmdocs/ECMP1196798/html/GUID-5FAA5445- 0872-400B-B7AD-B27CEE3D770A.html

• Question 29:

  You have a volume in an SVM that needs to be moved to a different SVM. You do not have room to copy the volume to the other SVM. Which ONTAP command will accomplish this task?

  A. volume rehost
  B. volume mount
  C. volume modify
  D. volume move
  A. volume rehost

  ---

  If you have been working with Netapp Clustered Data Ontap for a while now you would no doubt have performed quite a few volume moves. However one limitation of the volume move command was that you couldn't move the volume between storage virtual machines (SVM's). Starting with Ontap 9 we can now move a volume between Storage Virtual Machines (SVM's). This is done with the volume rehost command.

• Question 30:

  To configure high availability within a FAS8080 EX HA pair, which two statements are correct? (Choose two.)

  A. Connect the NVRAM HA interconnects between the nodes in the HA pair.
  B. Cable the cluster interconnects to the interconnect switch.
  C. Connect multiple FC paths from the controllers to the hosts.
  D. Connect both the local node and partner node to disk shelves using multipath HA.
  A. Connect the NVRAM HA interconnects between the nodes in the HA pair.
  C. Connect multiple FC paths from the controllers to the hosts.

  ---

  A: If an NVRAM HA adapter fails, the node automatically fails over to its partner node. The partner (takeover) node serves data for both of the nodes. References: https://library.netapp.com/ecm/ecm_download_file/ECMP1610209
