Question 1

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)

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

BKeep the SAN LIF online before it is moved

CTake the SAN LIF offline before it is moved

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

Answer : C, D

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 2

You are installing an AFF A250 system with ONTAP 9.8 software. Your customer asks you about the recommended LIF configuration for the ISCSI protocol. In this scenario, which two statements are correct

(choose two)

AEach node in an ISCSI configuration must be connected to a minimum of two ethernet switches

BAll LIFs from the SVM are connected to a single Ethernet switch

CEach SVM in an ISCSI configuration must have a minimum of two LIFs per node

DEach SVM in an ISCSI configuration must have a minimum of one LIF per node

Answer : A, C

It is recommended that all SVMs in ISCSI configurations have a minimum of two LIF's per node in separate Ethernet networks for redundancy and MPIO across multiple paths.

Question 3

You created a LUN in a new volume on your Netapp ONTAP cluster. You enabled the default snapshot schedule and enabled snapshot autodelete on the volume. In this scenario, in which three situations

does the snapshot autodelete feature automatically delete snapshot copies in the volume? (choose three)

AThe snapshot reserve space is nearly full

BThe LUN is nearly full

CThe overwrite reserve space is full

DThe volume is nearly full

EThe aggregate is nearly full

Answer : A, C, D

Depending on what is selected in the 'Trigger' option, Snapshot Autodelete will automatically delete a snapshot when, either the volume space utilized, or the snapshot reserve reaches a threshold capacity

specified below.

Automatic deletion of Snapshot copies from flexible volumes Data ONTAP can automatically delete one or more Snapshot copies on the volume, provided the Data ONTAP Snapshot copy autodeletion

policy is enabled and set to trigger when the overwrite reserve is nearly full on the volume.

Question 4

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?

ASpace reservation honored is set to false

BSpace reservation is set to disabled

CClone Autodelete Enabled is set to false

DSpace Allocation is set to disabled

Answer : D

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.

Question 5

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)

AUse existing zoning on fabric switches

BEnable NVMe/FC on the existing FC SVM

CUpgrade your FC switches from 16GB to 32GB

DCreate new zoning on fabric switches

Answer : A, B

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 6

You want to perform online data migration using Foreign LUN Import. In this scenario, which two conditions are required to support this task? (choose two)

AISCSI protocol LIFs must be added to the data SVM

BISCSI targets must be added to the ONTAP ISCSI initiator

CFCP protocol LIFs must be added to the data SVM

DFCP initiator ports must be available

Answer : C, D

FLI does not support iSCSI connections directly. In order for iSCSI LUNs to be migrated using FLI, the LUN type must be changed to FC. After the migration is complete, the LUN type is changed back to

iSCSI.

Question 7

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)

AAdd an Ethernet network adapter

BSelect the ''enable multi-path'' checkbox on the ISCSI software initiator

CAdd a converged network adapter (CNA)

DEnable MPIO by selecting the option in the MPIO properties administrative application

Answer : B, D

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
