NEW QUESTION 1

Exhibit.
NS0-520 dumps exhibit
You are moving volumes between aggregate aft_01_aggr1 and the aggregate Aggr_Data shown in the exhibit. How much space will be moved?

  • A. 11.17 TB
  • B. 935.75 GB
  • C. 296 KB
  • D. 1. 91 TB

Answer: C

NEW QUESTION 2

You have three Windows servers and one Linux server, each with dual-ported HBAs that are connected into a dual fabric.
In this scenario, what is the minimum number of zones that you need to create within each fabric switch?

  • A. 8
  • B. 1
  • C. 4
  • D. 2

Answer: A

NEW QUESTION 3

Which formula is appropriate for calculating target port Queue Depth?

  • A. The number of LIFs using a physical port * 256
  • B. The sum of the Queue Depth setting for all hosts using a physical port
  • C. The number of LIFs using the physical port * Maximum Host HBA Queue Depth setting
  • D. The number of physical ports * 2048

Answer: C

NEW QUESTION 4

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

Answer: B

Explanation:
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.

NEW QUESTION 5

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)

Answer: AD

NEW QUESTION 6

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.

Answer: A

NEW QUESTION 7

Which two are supported in ONTAP 9.5? (Choose two.)

  • A. an NVMe LIF and an FC LIF in the same SVM
  • B. an NVMe LIF associated with an FC Direct Connect port
  • C. a NVMe LIF and an FC LIF associated with the same port
  • D. multiple NVMe LIFs in the same SVM

Answer: CD

NEW QUESTION 8

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

NEW QUESTION 9

Which two features does Assymmetric Namespase Access (ANA) support? (Choose two.)

  • A. multipathing
  • B. LUN masking
  • C. LUN hosting
  • D. path management

Answer: AD

NEW QUESTION 10

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

Answer: BD

Explanation:
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

NEW QUESTION 11

A customer’s NetApp infrastructure is reaching end-of-life (EOL), and they want to inventory their NetApp cluster. The customer wants to make sure that the proposed technical refresh satisfies their growing data demands.
Which two tools would you use to help with this recommendation? (Choose two.)

  • A. Upgrade Advisor
  • B. OneCollect

NEW QUESTION 12

What is the default Ethernet packet size (or MTU - Maximum Transmission Unit) for Ethernet ports on Ethernet switches?

  • A. 2112 bytes
  • B. 9000 bytes
  • C. 1500 bytes
  • D. 12000 bytes

Answer: C

NEW QUESTION 13

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

Answer: CD

Explanation:
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.

NEW QUESTION 15

A customer recently added two nodes with FC ports to a 4-node cluster.
Which SVM configuration is needed before the customer creates LUNs on the new nodes?

  • A. The FC service needs to be enabled on the data SVM.
  • B. The existing LIFs need to be migrated to the new nodes.
  • C. New FC LIFs need to be created on the cluster SVM.
  • D. New FC LIFs need to be created on the new nodes.

Answer: D

NEW QUESTION 16

You are configuring FC ports on front-end SAN switches for a 4-node Metrocluster configuration across two data centers. You need to ensure that each data center serves FC LUNs when an FC port goes
offline in one data center. In this scenario, which front end switch setting must be modified to avoid overlap when a new port comes online?

  • A. NPIV enabled
  • B. NPIV reject
  • C. WWPN reject
  • D. ANA mapped
  • E. WWNN reject

Answer: A

Explanation:
Best practice: NPIV is required for FC LIFs to operate correctly. Before creating FC LIFs, make sure that any fabrics attached to an ONTAP system have NPIV enabled.
