NS0-520 Online Practice Questions and Answers

You are planning to implement a 32 Gb FC SAN on a 2-node AFF A700 ONTAP 9.5 cluster. You need to create 112 FC LIFs across the HA pair with a limit of 20 FC LIFs per physical HBA port.

In this scenario, how many 2-port 32 Gb HBA cards do you need per storage controller?

A. 2

B. 1

C. 4

D. 3

Referring to the exhibit, which two elements are required for NVMe host access with ONTAP 9.5 and using supported AFF nodes? (Choose two.)

A. You need 16 Gb FC HBAs installed in the AFF nodes.

B. You must have the license installed for NVMe support in the cluster.

C. You must have the license installed for FC support in the cluster.

D. You need 32 Gb FC HBAs installed in the AFF nodes.

You are troubleshooting high CPU use on a FAS8200 with all SAS HDDs. You have SAN hosts with LUNs in a volume named vol1. You want to reduce CPU use and maintain storage efficiencies. Referring to the exhibit which three actions will accomplish this task? (Choose three.)

A. Disable compression.

B. Enable cross-volume deduplication.

C. Disable inline deduplication.

D. Enable post process deduplication.

E. Enable data compaction.

An enterprise customer has both a NetApp FAS8200 4-node cluster and a third-party storage array in a shared SAN environment. The host servers connect to both storage vendors' arrays in the fabric.

Regarding (he hosts in this scenario, what are- two NetApp best practices when performing this task? (Choose two.)

A. Set the default timeout values and storage parameters for the host system.

B. Provide isolation between storage systems using NetApp's multitenancy feature.

C. Always use the same adapter for heterogeneous storage systems.

D. Use separate adapters to connect to each vendors' storage system.

A customer experiences intermittent connectivity problems between an ESXi server and FC LUNs in an SVM. The customer has examined the nodes hosting the LUNs and both the disk and CPU performance are below 50% utilization. The customer examined the switch ports connected to the storage array, and they ate also below 50% utilization.

Which two steps would you perform next in this scenario? (Choose two.)

A. Verify that the host is using SnapDrive.

B. Verify that the host Ethernet interfaces are using jumbo frames.

C. Verify that the host recommended settings were applied by Virtual Storage Console.

D. Verify that the HBA queue depth is set properly.

You want to provision an iSCSl LUN.

Which two steps are required to accomplish this task? (Choose two.)

A. Add the initiator IP address to the igroup.

B. Map the LUN to the igroup.

C. Add the target WWPN to the igroup.

D. Add the initiator 1QN to th

You have a 4-node cluster with a FAS8200 HA pair and an AFF A300 HA pair. You need to migrate a LUN from a FAS8200 node to an AFF A300 node for faster performance.

Which method will non-disruptively migrate the LUN to the AFF A300 while retaining snapshots of the LUN on the FAS8200?

A. You move the LUN.

B. You relocate the aggregate.

C. You move the volume.

D. You copy the LUN.

After completing the configuration of a new Brocade Fibre Channel switch, which command do you use to verify your configuration?

A. switchshow

B. show config

C. configshow

D. cfgshow

A customer has a 4-node cluster consisting of a FAS8020 system and an AFF A220 that is running ISCSI workloads across two separate SVMs. The FAS8020 system is reaching end of support, so they add a new AFF A400 system to migrate workloads off the FAS8020 system. The customer wants to migrate data off the FAS8020 aggregate n1_aggr1 on SVM2 to the AFF A400 aggregate n5_aggr1 on SVM1.

A. Volume move

B. Volume rehost

C. Volume reallocation

D. Aggregate reallocation

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
