NetApp NCIE SAN ONTAP NS0-520 Questions & Answers

• Question 21:

  You want to use ANA on SUSE Enterprise Linux. Which two components need to be verified in this scenario? (choose two)

  A. Verify the version of ONTAP

  B. Verify the version of SUSE Enterprise Linux

  C. Verify that ALUA must be enabled

  D. Verify that the ANA driver is installed

  Correct Answer: AB

  ANA Supportability

  NVMe/FC is supported on ONTAP 9.6 or later for the following versions of SLES:

  SLES15 SP1

  SLES15 SP1 host can run both NVMe/FC, and FCP traffic through the same fibre channel initiator adapter ports.

• Question 22:

  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

  Correct Answer: C

  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

• Question 23:

  You have a Netapp ONTAP cluster and are configuring ISCSI for some new hosts . You want to ensure that ISCSI connectivity can survive physical network failures. In this scenario, which two features would help fulfill this requirement? (choose two)

  A. Broadcast domains

  B. Failover groups

  C. MPIO

  D. Interface groups

  Correct Answer: CD

  Broadcast Domains are used to segment and create failover groups automatically... Broadcast Domain do not guarantee redundancy on ISCSI because failover groups are not used on ISCSI.

  

  Graphical user interface, text, application, email

• Question 24:

  You install an ASA AFF A400 system with 32 GB FC SFP+ modules in port 0e and 0f. After creating the SVM and configuring the FCP protocol, the physical port stays offline. Referring to the exhibit which statement is correct?

  

  A. The current type of the ports must be configured as an initiator

  B. The current mode to the ports must be configured as an FC port

  C. The current mode for the ports must be set as an NVMe/FC port

  D. The admin status is manually set to down

  Correct Answer: B

  Before using your UTA ports on a FC infraestructure, you need to modify the current mode from CNA to FC. You need to set the ports offline before you modify that parameter.

• Question 25:

  You have deployed a FAS8300 system and wait to enable SAN protocols. In this scenario, which two protocols are available to serve SAN data? (Choose two)

  A. Infiniband

  B. ISCSI

  C. NVMe

  D. FCP

  Correct Answer: BD

  

  Graphical user interface You can find more information on this link: https://hwu.netapp.com/Resources/Posters/POSTER-NA-380-1019.pdf?tag=8070

• Question 26:

  You are a system administrator and responsible for a Netapp AFF A800 2-node ONTAP 9.8 cluster that is used only for SAN. Your SAN uses FC and FCoE on the same Cisco switches. You want to add NVMe from the ONTAP controller to the same Cisco fabric. Which two statements are correct in this scenario? (choose two)

  A. The same SVM can serve both the FC and the FCoE protocols

  B. The same SVM cannot serve both the FC and the NVMe protocols

  C. FCoE and NVMe can share the same physical port

  D. FC and NVMe can share the same 32 GB physical port

  Correct Answer: AD

  FC and FC-NVMe can share the same 32 Gb physical port The same SVM can serve both FC and NVMe protocols using the same physical infraestructure wiith different LIFs FCoE and NVMe can NOT share the same infraestructure, they go trough different physical hardware https://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.dot-cm- sanconf%2FGUID-7D5EA321-97AE-497D-9925-BEF2553DF9F1.html

• Question 27:

  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

  Correct Answer: ACD

  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.

• 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

  Correct Answer: A

  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 100GB volume with the space guarantee set to volume, This volume contains two space reserved 20 GB LUNs. Both LUNs are at 50% use. You then create a snapshot copy of the volume. No modifications were performed since the snapshot copy was completed, and all actions were performed using the CLI. In this scenario, how much free space does the volume have?

  A. 60 GB

  B. 20 GB

  C. 40 GB

  D. 80 GB

  Correct Answer: A

  Both LUN created are inheriting the space reserved parameter from its volume parent, so both LUNs are thick provisioned using 20 GB each one of them and the snapshots have not increased because there has not been any changes since their creation 100GB - 20 GB - 20GB

• Question 30:

  Which NetApp tool provides a detailed inventory of SAN components?

  A. Active IQ OneCollect

  B. Interoperabilty Matrix Tool

  C. Active IQ config advisor

  D. Hardware Universe

  Correct Answer: A

  ActiveIQ OneCollect is a tool from NetApp that will create an inventory of your environment that will include hosts, switches and storage and validate it against the IMT (Interoperability Matrix Tool).
