NetApp NetApp Certifications NS0-520 Questions & Answers

• Question 201:

  A. LUN mapping with igroup

  B. host HBA speed settings

  C. FC target port setting on NetApp node

  D. FC switch zoning

  Correct Answer: C

• Question 202:

  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.

  Correct Answer: D

  A. Enable the iSCSI service.

  B. Bind the iSCSI ports to the software iSCSI adapter.

  C. Install Virtual Storage Console (VSC) for VMware.

  D. Enable BGP on the switch.

  E. Configure MTU 1500 on the switch.

  Correct Answer: BCE

• Question 204:

  

  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.

  Correct Answer: C

• Question 205:

  Which path selection policy is used by Windows Servers using NetApp LUNs that are greater than 2 TB?

  A. Least Queue Depth

  B. Round Robin

  C. Round Robin with Subset Policy

  D. Least Weighted Paths

  Correct Answer: C

• Question 206:

  

  You configured a SAN host with a 4-node ONTAP 9.5 cluster that uses default settings. All paths are available from the host to the four nodes. You have a requirement to see only two paths to each LUN. One path is optimized and the other is non-optimized.

  In this scenario, which NetApp SAN feature supports this requirement?

  A. portsets

  B. SLM

  C. VLANs

  D. igroups

  Correct Answer: C

• Question 207:

  

  An administrator has an ONTAP cluster with SVMs and LUNs as shown in the exhibit. Hosts attempting to connect to LUNs mapped from SVM "C" are unable to see their LUNs. The hosts are not configured to connect to any other SVM.

  Which action should be performed to restore multi-path connectivity to the LUNs in this scenario?

  A. Create LIFs on SVM "C" for host connectivity.

  B. Move the LUN to a different volume within SVM "C".

  C. Move the LUN to SVM "E" to restore connectivity.

  D. Move the LUN to SVM "A" to restore connectivity.

  Correct Answer: A

• Question 208:

  You want to connect a NetApp AFF A700 to a 32 Gb FC switch. The ports need to connect at 32 Gb speed. In this scenario, which statement is correct?

  A. The AFF A700 includes FC ports natively on the controller.

  B. The AFF A700 includes an additional FC I/O module that is already populated in each controller.

  C. You need to purchase a two-port or four-port unified I/O module that enables FC and Ethernet connectivity.

  D. You need to purchase a two-port or four-port FC I/O module.

  Correct Answer: C

• Question 209:

  

  You have a requirement to serve LUNs with under 200 microsecond latency using local server lass memory. You also are required to use a shared SAN.

  Using MAX Data as shown in the exhibit, which two LUN access protocols are supported with this solution? (Choose two.)

  A. iSCSI

  B. FCoE

  C. FC

  D. NVMe

  Correct Answer: D

• Question 210:

  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 LUNs that use under 5000 IOPS are moved to a FAS8200 using the lun move command.

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

  A. The new written data is not compacted.

  B. The new written data is compacted.

  C. The existing data is compacted.

  D. The existing data is not compacted.

  Correct Answer: BD
