  Correct Answer: C

  

  Graphical user interface, text, application, email You can find more information on this link: https://www.netapp.com/pdf.html?item=/media/10379-tr4515.pdfandv=20217121554 (11)

• Question 33:

  During maintenance of an AFF A250 node, you want to move the SAN LIFs that are members of a port set. In this scenario, which two statements are true? (choose two)

  A. You must disable SLM for the node that hosts the LIF

  B. You need to disable the zoning of the LIF WWPN

  C. The LIF must be removed from the port set

  D. You must take the SAN LIF offline

  Correct Answer: CD

  If the LIF is a member of a port set, the LIF must have been removed from the port set before the LIF can be moved to a different node.

  Change the status of the LIF to down (offline)

• Question 34:

  Which FC service is used by a host for discover service to locate FC targets that are available?

  A. The fabric configuration server

  B. The fabric name service

  C. The fabric zone server

  D. A. The fabric security server

  Correct Answer: B

  When a node is connected to the FC SAN, each SVM registers the World Wide Port Name (WWPN) of its LIF with the switch Fabric Name Service.

• Question 35:

  You need to migrate boot LUNs from a third-party array onto a Netapp FAS8700. Which three actions are required to complete this task? (choose three)

  A. Reboot the third-party SAN to prepare for the LUN Import

  B. Verify third-party array support by using the Interoperability Matrix Tool (IMT)

  C. Convert every FC target port on each controller to an FC initiator port

  D. Convert a single FC port on each controller to an FC initiator port

  E. Create zoning between the third-party array to the FAS8700

  Correct Answer: BDE

  We only need to convert one FC to initiator per node, if you need to enable multipath with 2 switches, then you need 2 ports on initiator mode per node

• Question 36:

  A customer wants to deploy NVMe/FC along with an existing FC SAN fabric using ONTAP 9.8. In this scenario, which two actions are correct? (choose two)

  A. Use existing zoning on fabric switches

  B. Enable NVMe/FC on the existing FC SVM

  C. Upgrade your FC switches from 16GB to 32GB

  D. Create new zoning on fabric switches

  Correct Answer: AB

  Because NVMe/FC simply swaps command sets from SCSI to NVMe, it is an easy transition to make. NVMe/FC uses the same FC transport and therefore the same hardware from the host, through the

  switch and all the way to the NVMe/FC target port on the storage array. Thus, NVMe/FC implementations can use existing FC infrastructure, including HBAs, switches, zones, targets, and cabling.

• Question 37:

  Which two components should be installed to support VMware VMFS6 datastores in an environment with only Ethernet switches? (Choose two)

  A. V_StorageAttach license

  B. Host Utilities

  C. NetApp Virtual Storage Console

  D. iSCSI licenses

  Correct Answer: CD

  Installing VSC is the best practice recommended by Netapp when you use VMware and this is an environment with only Ethernet switch, so ISCSI licenses are needed to present LUNs to the Virtual environment.

• Question 38:

  An administrator has migrated an ISCSI LUN with Foreign LUN Import (FLI) tool. The migrated LUN is presented on the new system, but it is not visible to the host. In this scenario, which additional action must be completed to make the LUN visible?

  A. Bind the igroup to a port set

  B. Install ANA software on the host

  C. Stop the FCP service

  D. Map the LUN to an ISCSI igroup

  Correct Answer: D

  Installing ANA is related with NVMe protocol Binding an igroup to a port set will only limit our paths Stopping the FCP service will not affect at anything, because this is an ISCSI LUN When you migrate ISCSI using FLI, you need to map the LUNs to an igroup where the destination arrays is added, after the LUN has been imported, you can create a new iSCSI igroup and add the hosts to the igroup You can find more information on this link: https://www.netapp.com/pdf.html?item=/media/17060-tr4380pdf.pdf (page 71)

• Question 39:

  You want to move a SAN LIF and preserve its configuration information and avoid rezoning the switch fabric. In this scenario, which two steps must be performed to fulfill this goal? (Choose two)

  A. Move the SAN LIF to another node in a cluster on a different storage virtual machine (SVMs)

  B. Keep the SAN LIF online before it is moved

  C. Take the SAN LIF offline before it is moved

  D. Move the SAN LIF to another node in a cluster on existing storage virtual machine (SVMs)

  Correct Answer: CD

  Moving SAN LIFs If a node needs to be taken offline, you can move a SAN LIF to preserve its configuration information, such as its WWPN, and avoid rezoning the switch fabric. Because a SAN LIF must be taken offline before it is moved, host traffic must rely on host multipathing software to provide nondisruptive access to the LUN. You can move SAN LIFs to any node in a cluster, but you cannot move the SAN LIFs between storage virtual machines (SVMs).

• Question 40:

  What are two benefits of implementing VLANs for ISCSI configuration? (choose two)

  A. Reduced number of broadcast domains

  B. Increased performance

  C. Increased security

  D. Increased resiliency

  Correct Answer: AC

  When you implement VLANs in large IP network infrastructures, you derive the following benefits:

  Increased security.

  VLANs enable you to leverage existing infrastructure while still providing enhanced security because they limit access between different nodes of an Ethernet network or an IP SAN.
