  E. Configure MTU 1500 on the switch.

• Question 132:

  You have a 4 node cluster with an AFF A300 HA pair and a FAS8200 HA pair. You plan on using the default storage efficiency settings. With inline data compaction, you estimate that you can save 6% of storage space. AFF A300 LUNs that use under 5000 IOPS are moved to a FAS8200 using the lun move command.

  In this scenario, what happens to the data after the LUN is moved? (Choose two.)

  A. The new written data is not compacted.
  B. The new written data is compacted.
  C. The existing data is compacted.
  D. The existing data is not compacted.
  B. The new written data is compacted.
  D. The existing data is not compacted.

• Question 133:

  Which three components are required for NetApp iSCSI LUN access on Linux servers? (Choose three.)

  A. device-mapper-multipath
  B. NetApp SnapDrive
  C. scsi-target-utils
  D. iscsi-initiator-utils
  E. NetApp Host Utilities
  A. device-mapper-multipath
  C. scsi-target-utils
  E. NetApp Host Utilities

• Question 134:

  You are about to replace a failed Brocade Fibre Channel switch. Which three steps do you take prior to connecting the switch in the SAN? (Choose three.)

  A. Force the new switch to be the principle switch.
  B. Change the domain ID of the replacement switch to the domain ID of the failed switch.
  C. Clear all zoning configurations on the replacement switch.
  D. Change the core PID format of the replacement switch to the core PID format of the failed switch.
  E. Preload the zoning information from the fabric onto the new switch.
  B. Change the domain ID of the replacement switch to the domain ID of the failed switch.
  C. Clear all zoning configurations on the replacement switch.
  D. Change the core PID format of the replacement switch to the core PID format of the failed switch.

• Question 135:

  You are configuring a 4-node AFF A400 ONTAP 9.8 cluster. The data center switches have limited ports, and you are given one 10-Gigabit Ethernet port per node for external access.

  In this scenario, which three protocols share the same physical port? (Choose three)

  A. NVMe/FC
  B. ISCSI
  C. FCoE
  D. Snapmirror
  E. FC
  B. ISCSI
  C. FCoE
  D. Snapmirror

  ---

  Explanation/Reference:

  If we have only ethernet switches available, we can only enable protocols over ethernet such as FCoE, ISCSI and Snapmirror. NVMe/FC and FC need a SAN Fabric switch to work.

• Question 136:

  You have a Netapp ONTAP cluster and are configuring ISCSI for some new hosts . You want to ensure that ISCSI connectivity can survive physical network failures. In this scenario, which two features would help fulfill this requirement? (choose two)

  A. Broadcast domains
  B. Failover groups
  C. MPIO
  D. Interface groups
  C. MPIO
  D. Interface groups

  ---

  Explanation/Reference:

  Broadcast Domains are used to segment and create failover groups automatically... Broadcast Domain do not guarantee redundancy on ISCSI because failover groups are not used on ISCSI.

  

  Graphical user interface, text, application, email

• Question 137:

  An administrator is planning a hardware refresh and data migration from a Data ONTAP 7.3 system to new AFF A3-00 cluster that is using ONTAP 9.0. The Mode system only serves FC LUNs to a Windows 2012Rs server cluster that needs to remain connected after migration Referring to the scenario, which method would be used for the LUN migration.

  A. Unified Host Utility Kit
  B. 7-Mode Transition Tool (7MIT)
  C. Foreign LUN import (FLI)
  D. Oncommand system Manager
  B. 7-Mode Transition Tool (7MIT)

• Question 138:

  A customer is deploying a SAN cluster of A700 nodes and wants to ensure that the SAN cluster will maintain a quorum in the event of a rack level power failure. Which two statements are true in this scenario? (choose two.)

  A. Six nodes are required
  B. Four nodes are required
  C. Three racks are required
  D. Two racks are required
  A. Six nodes are required
  C. Three racks are required

  ---

  Explanation/Reference:

  The quorum rule states that to make changes to the configuration in our cluster, we need to have more than half of the nodes available. This prevents configuration conflicts if we lose connectivity between the nodes in our cluster.

  So, if we have only 2 racks and 4 nodes we could never get more than half of the nodes available if one of those racks power fails.

  We need 6 nodes separated on 3 racks, so we can have more than half of the nodes available if one of those racks power fails.

• Question 139:

  After the addition of extra DS224C disk shelves, you notice that the output of the system node run -node node_1 sysconfig command shows Mixed-path. You need to investigate why the additional shelves are providing this error. In this scenario, which two tools would help diagnose this issue? (Choose two.)

  A. Config Advisor
  B. Active IQ
  C. Hardware Universe (HWU)
  D. Interoperability Matrix Tool (IMT)
  A. Config Advisor
  D. Interoperability Matrix Tool (IMT)

• Question 140:

  You are provisioning a LUN using an ISCSI initiator on an ESX host. You disable Ethernet flow control for all ports but are experiencing Performance issues. In this scenario, which two actions would improve the performance issue? (Choose two.)

  A. Set the MTU settings 1500 for optimal performance.
  B. Dedicate your ports to ISCSI traffic.
  C. Enable jumbo frames across the entire data path.
  D. Confirm that your host .mil storage polls are connected to a different network.
  B. Dedicate your ports to ISCSI traffic.
  C. Enable jumbo frames across the entire data path.
