• Question 142:

  File deletions from a SAN-attached host that is using Windows Server 2016 are not freeing up space in LUN lun3. Referring to the exhibit, which setting is preventing the SCSI UNMAP operation?

  A. Space reservation honored is set to false
  B. Space reservation is set to disabled
  C. Clone Autodelete Enabled is set to false
  D. Space Allocation is set to disabled
  D. Space Allocation is set to disabled

  ---

  Explanation/Reference:

  For clustered Data ONTAP, support for SCSI UNMAP begins in the 8.2 release family. For a LUN to advertise support for and accept SCSI UNMAP commands, enable the space- allocation option on LUNs which you expect to use this feature

  with.

  B. CHAP configured on HOST A and the NetApp Storage System
  C. igroup setup with no IQNs
  D. IPsec configured on both host A and the NetApp Storage System
  B. CHAP configured on HOST A and the NetApp Storage System

• Question 146:

  You are configuring a Windows Server 2019 system to attach to an ISCSI presented LUN. There are multiple physical paths from the Windows Server to the Netapp Cluster. Which two changes are required to the Windows Server to enable multipath? (choose two)

  A. Add an Ethernet network adapter
  B. Select the "enable multi-path" checkbox on the ISCSI software initiator
  C. Add a converged network adapter (CNA)
  D. Enable MPIO by selecting the option in the MPIO properties administrative application
  B. Select the "enable multi-path" checkbox on the ISCSI software initiator
  D. Enable MPIO by selecting the option in the MPIO properties administrative application

  Explanation/Reference:

  Select Enable multi-path, select Automatically restore this connection when the computer starts or Add this connection to the list of Favorite Targets, and then click Advanced You can find more information on this link: https://docs.netapp.com/ontap-9/topic/com.netapp.doc.exp-iscsi- cpg/iSCSI%20express%20configuration%20for%20Windows.pdf (15)

• Question 147:

  A customer is expanding an ONTAP 9.4 switchless 2-node FAS2750 cluster. Two AFF A220 nodes will be added to the cluster. In addition to the cluster nodes, what else is required to perform the cluster expansion?

  A. Additional management switches are required.
  B. An upgrade to ONTAP 9.5 is required.
  C. Cluster switches are required.
  D. Additional DS224C shelves are needed.
  A. Additional management switches are required.

• Question 148:

  An administrator has a 2node AFF ONTAP cluster named cl1. A Windows 2016 server has 10 FC LUNs mapped from the cluster , and the administrator can multiple paths to each LUN, During a scheduled storage failover, node cl1-02 took over cl1-01, and Windows server lost connectivity to all mapped LUNs but reestablished connectivity after the giveback operation finished.

  In the scenario, what would cause the LUN connectivity outage?

  A. Multipathing software is not installed on the host.
  B. Switch zoning does not exist between the host initiator ports and the data LIFs that reside no node cl-01.
  C. NPIV is not enabled on the switches.
  D. Switch zoning does not exist between the host initiator ports and the data LIFs that reside on node cl1-02.
  A. Multipathing software is not installed on the host.

• Question 149:

  You are configuring a VMware sphere host for FC access to a Netapp ONTAP cluster. In this scenario, which two tasks does Netapp recommend performing on the Vsphere host? (choose two)

  A. Set the queue depth on the host to 8
  B. Update the HBA driver
  C. Zone the host by using the host WWNNs
  D. Use the Netapp Virtual Storage Console to configure the host settings
  B. Update the HBA driver
  D. Use the Netapp Virtual Storage Console to configure the host settings

  ---

  Explanation/Reference:

  Zoning the host using WWNNs is not recommended. Netapp always recommends to use WWPN to zone correctly.

  We can not stablish a queue depth value because we don't have the amount of ports and hosts to calculate the recommended queue depth

  Installing VSC and updating the HBA driver are best practices recommended by Netapp You can find more information on this link:

• Question 150:

  You have a SAN host that is only sending traffic to an ONTAP cluster using active non- optimized paths. In this scenario, over which network type does the node that is hosting the target LUN receive the traffic?

  A. Fibre Channel network
  B. Cluster network
  C. ISCSI network
  D. Intercluster network
  B. Cluster network

  ---

  Explanation/Reference:

  The Cluster Network This is used for traffic that is going between the nodes themselves, such as system information that is being replicated between the nodes. Also, if incoming client data traffic hits a network port on a different controller than the one which owns the disks, that traffic will also go over the cluster network.
