NetApp NS0-520 Online Practice Questions and Exam Preparation

NetApp NS0-520 Online Questions & Answers

• Question 21:

  You have finished deploying a Netapp AFF All SAN Array Cluster and want to test the persistent ports feature. In this scenario, how would you accomplish this task?

  A. Perform a takeover of a node
  B. Disconnect an FCP initiator port
  C. Disconnect an FCP target port
  D. Disable a SAN LIF
  A. Perform a takeover of a node

  ---

  Explanation/Reference:

  If we don't have OnCommand Insight, then we should not pull out a cable as test because it won't be detected properly. Doing a planned takeover will meet the requirements asked.

• Question 22:

  

  A customer is using both FC and NVMe in a cluster. The customer needs to do some work on AFF_1. Referring to the exhibit, what will happen?

  A. The NVMe namespaces on AFF_2 will be available after takeover of AFF_1.
  B. The FC LUNs that use cluster interconnect to access the LUNs on AFF_1 will be unavailable after failover.
  C. The FC LUNs on node AFF_2 will be unavailable after failover of AFF_1.
  D. The NVMe namespaces on AFF_1 will be unavailable after takeover by AFF_2.
  C. The FC LUNs on node AFF_2 will be unavailable after failover of AFF_1.

• Question 23:

  An administrator is adding new hosts to a vSphere cluster. The cluster uses the FC protocol to connect to a NetApp cluster. The administrator wants to configure the multipathing for the ESXi host. Which NetApp tool should be used to accomplish this task?

  A. OnCommand System Manager (OCSM)
  B. Host Utilities
  C. SnapCenter plug-in
  D. NetApp Virtual Storage Console (VSC)
  D. NetApp Virtual Storage Console (VSC)

• Question 24:

  After performing failover testing on a newly deployed MetroCluster configuration, some aggregates remain in a degraded state. Referring to the exhibit, which statement is true?

  

  A. The MetroCluster Tiebreaker software is misconfigured
  B. The ONTAP Mediator service is misconfigured
  C. A cluster switch is powered off
  D. A disk shelf is powered off
  D. A disk shelf is powered off

  ---

  Explanation/Reference:

  The aggregate with drives on the powered-off shelf should have a degraded RAID status, and drives on the affected plex should have a failed status You can find more information on this link: https://docs.netapp.com/us-en/ontap-metrocluster/install- ip/task_test_the_mcc_configuration.html#verifying-operation-after-loss-of-a-single-storage- shelf

• Question 25:

  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
  C. Config Advisor
  D. Active IQ
  A. Upgrade Advisor
  C. Config Advisor

• Question 26:

  Exhibit.

  

  You are asked to change the iSCSl Target Node Name of an SVM named SVM1 that is serving data. Referring to the exhibit, which two statements are correct? (Choose two.)

  A. Reconnect all the lUNs alter renaming the target node.
  B. Disable Selective LUN Mapping (SIM) and create port sets.
  C. Unmap and re-map the LUNs.
  D. Stop and start the iSCSI service.
  C. Unmap and re-map the LUNs.
  D. Stop and start the iSCSI service.

• Question 27:

  An administrator wants to design an NVMe solution to connect Linux hosts to an ONTAP cluster. The proposed solution uses two Cisco MDS 9396T switches for each fabric in a top-of-rack design. In this scenario, which statement is true?

  A. Asymmetric Namespace Access requires ONTAP 9.4 and higher.
  B. NVMe solutions require heterogeneous multiple switch fabrics.
  C. N_Port ID virtualization (NPIV) must be enabled on all switches.
  D. A middle-of-rack design is required.
  C. N_Port ID virtualization (NPIV) must be enabled on all switches.

• Question 28:

  During testing, an administrator notices that the wrong subsystem was returned using the NVMe discover command. The administrator was expecting test0_subsystem as the subsystem Referring to the exhibit, what would cause the discrepancy?

  

  A. The wrong NQN was mapped to the subsystem
  B. The wrong WWPN was used in the discovery command
  C. Asymmetric Namespace Access (ANA) was not properly configured
  D. The NVMe was not configured on the test0 SVM
  A. The wrong NQN was mapped to the subsystem

  ---

  Explanation/Reference:

  We can discard that ANA was not properly configured becase this is not a problem about multipathing. We can discard WWPN because this is an NVMe configuration where WWPN is not involved We can discard that NVMe was not configured because we wouldn't be able to even run that command if that's true Configure the NQN correctly is one of the steps when we configure NVMe You can find more information on this link: http://senthil-it-infrastructure.blogspot.com/2020/05/netapp-ontap-97-nvme-configuration- and.html

• Question 29:

  You have a 4-node FAS8200 A300 cluster that are using ONTAP 9.3 default settings. For faster performance, you move a volume with LUNs from a node on the FAS8200 to a node on the AFF A300. You determine that your SAN host is still using all active/optimized FC paths to the FAS8300 HA pair.

  What do you need to troubleshoot to move all active/optimized FC paths to the AFF A300 HA pair?

  A. reporting nodes list
  B. host MPIO and ALUA
  C. LUN mapping
  D. igroup WWPNs
  A. reporting nodes list

• Question 30:

  Exhibit.

  

  You are adding a boot LUN for a new server. The server uses FCP attached through a CNA. The ONTAP cluster is also attached to the same fabric by way of UTA2. You configure the zoning for the fabric as shown in the exhibit. You discover that the server cannot see its boot LUN.

  What is the problem with your zoning configuration?

  A. The zone set must have the same name as the zone.
  B. The zone was not activated.
  C. The zone used a wrong zone ID.
  D. The WWPN for the NetApp LIF is incorrect.
  D. The WWPN for the NetApp LIF is incorrect.
