NetApp NS0-520 Online Questions & Answers

• Question 1:

  Exhibit.

  

  Referring to the exhibit, which FC LIF would cause a path failure on a host connecting to a LUN?

  A. fcp_sanluns01prod02p0e
  B. fcp_sanluns01prod02p0g
  C. fcp_sanluns01prod02p0g
  D. fcp_sanluns0lptodOlp0e
  A. fcp_sanluns01prod02p0e

• Question 2:

  

  You have a performance critical database application that is running on a FAS9000 controller that uses FC. As shown in the exhibit, volume efficiency is enabled. If you follow the performance recommendation, what are two results to the data in the volume? (Choose two.)

  A. The new written data is compressed.
  B. The new written data is uncompressed.
  C. The existing data is uncompressed.
  D. The existing data is compressed.
  A. The new written data is compressed.
  C. The existing data is uncompressed.

• Question 3:

  Referring to the exhibit, which two actions would you perform to ensure that each host has valid multipathing? (choose two)

  

  A. Verify that the VLANs are properly configured on the switches
  B. Verify that the VLANs are properly configured on the ONTAP cluster
  C. Verify that ALUA is enabled on the switches
  D. Verify that ISCSI service is started on the ONTAP cluster
  A. Verify that the VLANs are properly configured on the switches
  B. Verify that the VLANs are properly configured on the ONTAP cluster

  ---

  Explanation/Reference:

  Iscsi is already started, we can not run those commands successfully if the protocol is not started ALUA is enabled on hosts, It is not enabled on switches VLANs are configured on the Netapp and switches, they need to be properly configured on both sides to work correctly You can find more information on this link: https://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.dot-cm- nmg%2FGUID-52AE6E9C-13B6-49BA-B030-545C1C7647AC.html

• Question 4:

  While changing the network connections on your ONTAP cluster from twinax to fiber, the ports experience network connectivity issues. You want to verify which speeds the ports support and ensure that you have supported transceivers. In this scenario which two actions would accomplish this task (choose two)

  A. Use hardware universe to determine the supported transceivers
  B. Use the interoperability matrix tool to determine the supported port speeds
  C. Use hardware universe to determine the supported port speeds
  D. Use the interoperability matrix tool to determine the supported transceivers
  A. Use hardware universe to determine the supported transceivers
  C. Use hardware universe to determine the supported port speeds

  ---

  Explanation/Reference:

  Hardware universe will show information about port speeds and transceiver compatbility You can find more information on this link: https://hwu.netapp.com/Resources/hwu_ug.pdf (page 73)

• 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?

  A. The SMB protocol will need to be used
  B. 10 GB switches are required for this configuration
  C. The environment will have to be configured with 1 GB networking
  D. Configure direct attached connections between the two hosts and storage
  D. Configure direct attached connections between the two hosts and storage

  ---

  Explanation/Reference:

  Direct-attachment

  In a direct-attached configuration, one or more hosts are directly connected to the controllers.

• Question 6:

  A company has 20 ESX hosts. Ten of the hosts are connected using FC, and the rest are connected over iSCSI. The FC host HBA queue depth is set to 32, and the iSCSI LUN queue depth is set to 64. The FC hosts are now experiencing random connectivity issues.

  In this scenario, what would be the reason for the disconnects?

  A. The FC host has a lower queue depth.
  B. According to the IMT, unsupported HBA firmware is in use.
  C. All of the hosts are part of the same cluster.
  D. The queue depth is not consistent across the cluster.
  A. The FC host has a lower queue depth.

• Question 7:

  You are configuring a new Netapp ONTAP cluster and are connecting the nodes to Cisco MDS SAN switches. You connect one of the nodes to switch port fc1/11 and run the commands that are shown in the exhibit. The SAN LIFs are enabled but are not operationally online, and none of the SAN hosts can access their LUNs on the ONTAP cluster.

  In this scenario, which configuration would cause this problem?

  

  A. Interoperability mode is not enabled on the switches
  B. The in-order guarantee is not enabled on the switch
  C. NPV is not enabled on the switches
  D. NPIV is not enabled on the switches
  D. NPIV is not enabled on the switches

  ---

  Explanation/Reference:

  in-order guarantee and interoperability mode are default configuration on a VSAN NPV is the core switch where NPIV is going to be enabled. The NPV core switch is defined as an upstream switch on which NPIV is enabled. The NPV core switch receives traffic that is passed to it from a downstream switch that has NPV enabled on it. A switch that is in NPV mode does not switch traffic; instead, it passes traffic to the upstream NPV core switch on which NPIV is enabled. After NPIV is enabled on the core NPV switch, the port should automatically come up (unless there are other issues).

• Question 8:

  You have a 4-node cluster with an AFF A300 HA pair and a FAS8200 HA pair. You plan on using the default storage efficiency settings. With inline data compaction, you estimate that you can save 6% of storage space. AFF A300 volumes that use under 5000 IOPS are moved to a FAS8200 using the volume move command.

  In this scenario, what happens to the data after the volume is moved? (Choose two.)

  A. The new written data is not compacted.
  B. The existing data is compacted.
  C. The new written data is compacted.
  D. The existing data is not compacted.
  A. The new written data is not compacted.

• Question 9:

  Exhibit.

  

  You are working on a project to install a new AFF A300 storage array. You use a pair of Nexus 3596 switches for FC connectivity between your VMware ESXi servers and the AFF A300.

  Which SAN switch feature must be enabled to accomplish this task?

  A. N_Port ID visualization (NP1V)
  B. Open Shortest Path First (OSPF)
  C. Link Aggregation Control Protocol (LACP)
  D. N_Port Visualization (NPV)
  A. N_Port ID visualization (NP1V)

• Question 10:

  A database administrator needs to ensure that snapshot copies of database files across multiple LUNs are taken at the same point in time. Which action achieves this outcome?

  A. Create each LUN within the same FlexVol volume
  B. Create each LUN on the same Fabric Pool aggregate
  C. Add each LUN volume to the same snapshot schedule
  D. Create each LUN within the same FlexGroup Volume
  A. Create each LUN within the same FlexVol volume

  ---

  Explanation/Reference:

  We can discard Flexgroup because it only works on NAS Protocols. We can discard LUNs and Aggregates because snapshots are not taken at that level Snapshots are taken at volume level You can find more information on this link: https://community.netapp.com/t5/ONTAP-Discussions/can-we-creat-multiple-luns-from- same-volume-on-AFF300/m-p/153049#M34153
