NetApp NCIE SAN ONTAP NS0-520 Questions & Answers

• Question 1:

  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)

  A. ISCSI protocol LIFs must be added to the data SVM

  B. ISCSI targets must be added to the ONTAP ISCSI initiator

  C. FCP protocol LIFs must be added to the data SVM

  D. FCP initiator ports must be available

  Correct Answer: CD

  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 2:

  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

  Correct Answer: A

  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 3:

  Which two requirements must be satisfied to run an Upgrade Advisor report on a Netapp All SAN Array? (choose two)

  A. The cluster nodes must have a valid support contract

  B. Autosupport must be enabled

  C. The vsadmin account must be enabled

  D. The Connectivity, Liveness, Availability Monitor (CLAM) must be enabled

  Correct Answer: AB

  To run Active IQ Upgrade Advisor the cluster must have a valid contract, and this tool gets information from Autosupport

  Active IQ Digital Advisor shows systems with a valid support contract.

• 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

  Correct Answer: AC

  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 upgraded your Linux hosts to SUSE Enterprise Linux 15. In this scenario, which two actions should you perform before you test asymmetric namespace access (ANA)? (Choose two)

  A. Verify if the NVMe service has started

  B. Verify if the LUNs and namespaces are in the same volume.

  C. Verify if the version of Netapp ONTAP software is 9.5 or later

  D. Verify if there is only one LIF in the SVM

  Correct Answer: AC

  

  ONTAP 9.5 Introduces ANA

• Question 6:

  You want configure namespaces to support NVMe over Fibre Channel (NVMe/FC) using ONTAP 9.8. Which action will accomplish this task?

  A. Add FC to the list of SVM protocols

  B. Remove any protocols from the SVM before adding the NVMe protocol

  C. Enable ALUA on the namespaces that should use the NVMe protocol

  D. Configure a LIF for the NVMe protocol

  Correct Answer: D

  Although ONTAP uses a NVMe/FC LIF that is separate from the FCP LIFs, both LIFs can be hosted on the same physical HBA port at both the host initiator and storage target.

  NVMe/FC and FCP can

  share the same physical infrastructure concurrently, so the same physical port, cable, switch port, and target port can simultaneously host and transmit both FCP and NVMe/FC frames

  NVMe can use the same FC infraestructure, but it needs to create a separate NVMe LIF to work.

• 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)

  A. Add an Ethernet network adapter

  B. Select the "enable multi-path" checkbox on the ISCSI software initiator

  C. Add a converged network adapter (CNA)

  D. Enable MPIO by selecting the option in the MPIO properties administrative application

  Correct Answer: BD

  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 You can find more information on this link: https://docs.netapp.com/ontap-9/topic/com.netapp.doc.exp-iscsi- cpg/iSCSI%20express%20configuration%20for%20Windows.pdf (15)

• Question 8:

  Your customer asks you to configure a newly installed FAS8300 for an FC host connection.

  Referring to the exhibit, which step accomplishes this task?

  

  A. Configure the ports 0e and 0f as a mode of CNA

  B. Configure the ports 0e and 0f as type of target

  C. Configure the ports 0e and 0f as status admin up

  D. Configure the ports 0e and 0f as status admin down

  Correct Answer: B

  To change the port type from initiator to target you need to take the port offline The ports need to be on target mode to present LUNs to the hosts.

• Question 9:

  You are testing FCP paths failures on a 2-node Netapp AFF All SAN Array and verify that persistent ports are correctly enabled. Before testing, a host sees four optimized paths to a LUN. You perform a node takeover and re-check the host.

  Which statement is true after the node takeover?

  A. The host sees four optimized paths to the LUN

  B. The host sees two non-optimized paths and two dead paths to the LUN

  C. The host sees two optimized paths and two non-optimized paths to the LUN

  D. The host sees two optimized paths and two dead paths to the LUN

  Correct Answer: A

  Support for persistent ports Beginning in ONTAP 9.8, persistent ports are enabled by default on All SAN Arrays (ASAs) that are configured to use the FC protocol. Persistent ports are only available for FC and require zone membership identified by World Wide Port Name (WWPN). Persistent ports reduce the impact of takeovers by creating a shadow LIF on the corresponding physical port of the HA partner. When a node is taken over, the shadow LIF on the partner node assumes the identity of the original LIF, including the WWPNe. Before the status of path to the taken over node is changed to faulty, the shadow LIF appears as an Active/Optimized path to the host MPIO stack, and I/O is shifted. This reduces I/O disruption because the host always sees the same number of paths to the target, even during storage failover operations.

• Question 10:

  An administrator enabled the FCP protocol on an SVM and created a boot LUN for a Windows Server 2019 server host. The host is attached using multiple paths to the storage SVM. After correctly adding the LUN to the igroup and setting its LUN ID to 1, the host is unable to boot using the installed FC HBA.

  A. The LUN ID must be set to 0

  B. The LUN ID must be set to 255

  C. During the boot process, using FCP is not supported by Netapp D. During the boot process, using FCP is not supported by Microsoft

  Correct Answer: A

  Create the LUN that you want to use as a boot device, and map it to the igroup as LUN ID You can find more information on this link: https://library.netapp.com/ecmdocs/ECMP1656701/html/GUID-76BFD6AC-BC2A-419A- 9DD3-D98423B2B67F.html
