NEW 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)

• A. The snapshot reserve space is nearly full
• B. The LUN is nearly full
• C. The overwrite reserve space is full
• D. The volume is nearly full
• E. The aggregate is nearly full

Answer: ACD

Explanation:
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. You can find more information on this link:

NEW QUESTION 5

You are asked to configure a small environment for a branch office. The customer has two new VMware ESXI hosts and a Netapp FAS2750 for the site. They want to allocate 10 GB for their ISCSI network to
be used for datastores. However, they do not want to purchase any new switches for the environment. In this scenario, Which statement is correct?

Answer: D

Explanation:
Direct-attachment
In a direct-attached configuration, one or more hosts are directly connected to the controllers. You can find more information on this link:

NEW QUESTION 6

On your ONTAP 9.5 cluster, you need to set up the onboard key manager with hardware-based security and volume encryption.
Which two licenses are required in this situation? (Choose two.)

• A. FDE
• B. TPM
• C. VE
• D. RSA

Answer: CD

NEW QUESTION 7

In an NVMe/FC environment, the host cannot discover the namespace on the AFF system. Referring to the exhibit, what is the problem?

• A. The host MPIO drivers are not installed
• B. NVMe is not supported on the FC adapter
• C. The NQN is not correct
• D. The NVMe service is not running on the SVM

Answer: C

Explanation:
We would not be able to run that command if NVMe is not enabled NVMe is supported on the same SVM along with FC protocol
The multipath tool on NVMe is called ANA
NQN needs to be correctly declared on the subsystem to map the new NVMe resources

NEW QUESTION 8

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

Answer: CD

Explanation:
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) You can find more information on this link:

NEW QUESTION 9

For which two purposes would the use of VLAN's be beneficial? (Choose two.)

• A. to isolate iSCSI traffic from LAN/WAN traffic
• B. to separate LAN from WAN traffic
• C. to isolate management traffic from other IP traffic
• D. to isolate UDP from TCP traffic in the IP network
• E. to isolate SSH traffic from other IP traffic

NEW QUESTION 10

You are implementing a new AFF A800 HA pair and are required to migrate NetApp E-Series E2624 data to the AFF A800 controllers. You do not have a host server that is available for the migration.
In this scenario, which NetApp migration method is supported?

• A. OnCommand Unified Manager (OCUM)
• B. NetApp Data Availability Services (NDAS)
• C. SnapMirror Synchronous (SM-S)
• D. Foreign LUN Import (FLI)

Answer: D

NEW QUESTION 11

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

Answer: B

NEW QUESTION 12

Exhibit.

A customer has an AFF A200 with a LUN residing in a volume by Node 4. The default Selection Mapping settings are effect. During a planned takeover cluster test, Node 3 performs a take over of Node 4.
Referring to the exhibit, what is the expected number of paths seen from the host?

• A. 6
• B. 8
• C. 4
• D. 2

Answer: A

NEW QUESTION 13

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

Answer: D

Explanation:
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
