A Review Of High Quality NS0-520 Testing Software

NEW QUESTION 1

Which two components should be installed to support VMware VMFS6 datastores in an environment with only Ethernet switches? (Choose two)

• A. V_StorageAttach license
• B. Host Utilities
• C. NetApp Virtual Storage Console
• D. iSCSI licenses

Answer: CD

Explanation:
Installing VSC is the best practice recommended by Netapp when you use VMware and this is an environment with only Ethernet switch, so ISCSI licenses are needed to present LUNs to the Virtual
environment.

NEW QUESTION 2

File deletions from a SAN-attached host that is using Windows Server 2016 are not freeing up space in LUN lun3. Referring to the exhibit, which setting is preventing the SCSI UNMAP operation?

• A. Space reservation honored is set to false
• B. Space reservation is set to disabled
• C. Clone Autodelete Enabled is set to false
• D. Space Allocation is set to disabled

Answer: D

Explanation:
For clustered Data ONTAP, support for SCSI UNMAP begins in the 8.2 release family. For a LUN to advertise support for and accept SCSI UNMAP commands, enable the space-allocation option on LUNs which you expect to use this feature with.

NEW QUESTION 3

You are configuring FC ports on front-end SAN switches for a 4-node Metrocluster configuration across two data centers. You need to ensure that each data center serves FC LUNs when an FC port goes
offline in one data center. In this scenario, which front end switch setting must be modified to avoid overlap when a new port comes online?

• A. NPIV enabled
• B. NPIV reject
• C. WWPN reject
• D. ANA mapped
• E. WWNN reject

Answer: A

Explanation:
Best practice: NPIV is required for FC LIFs to operate correctly. Before creating FC LIFs, make sure that any fabrics attached to an ONTAP system have NPIV enabled.

NEW QUESTION 4

You are provisioning a LUN using an ISCSI initiator on an ESX host. You disable Ethernet flow control for all ports but are experiencing
Performance issues.
In this scenario, which two actions would improve the performance issue? (Choose two.)

• A. Set the MTU settings 1500 for optimal performance.
• B. Dedicate your ports to ISCSI traffic.
• C. Enable jumbo frames across the entire data path.
• D. Confirm that your host .mil storage polls are connected to a different network.

Answer: BC

NEW QUESTION 5

An administrator configures NVMe within an SVM for a test environment. The administrator creates an NVMe namespace and an NVMe subsystem. The administrator then maps the namespace to the subsystem. However, when the administrator establishes a connection to a supported host, the following error message appears: No discovery log entries to fetch.
What is the solution to this error?

• A. Add the host WWPN to the subsystem.
• B. Disable the host HBA and re-enable it to clear the buffers.
• C. Add the host NQN to the subsystem.
• D. Use the nvme ns-rescan /dev/nvme0 command to rescan the bus.

Answer: C

NEW QUESTION 6

An administrator has six VMware hosts, each with dual HBAs that are connected to a dual fabric using single initiator multiple target zoning. Four nodes are being added to the existing 4-node ONTAP cluster.
In this scenario, what is the minimum number of FC zones that need to be updated on each fabric switch?

• A. 6
• B. 8
• C. 4
• D. 2

Answer: B

NEW QUESTION 7

As a system administrator, you perform a routine check of available storage space on your FAS2750. You notice that the vol_1 volume is approaching 100% capacity. The volume is configured with the space guarantee set to volume and the LUN reservation is disabled. You want to free up space in the volume without increasing its size.
Which action would accomplish this task?

• A. Increase the size of the LUN.
• B. Increase the Snapshot Reserve.
• C. Increase the aggregate size.
• D. Use deduplication.

Answer: C

NEW QUESTION 8

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)

Answer: A

NEW QUESTION 9

Which two features does Assymmetric Namespase Access (ANA) support? (Choose two.)

• A. multipathing
• B. LUN masking
• C. LUN hosting
• D. path management

Answer: AD

NEW QUESTION 10

You are provisioning storage to an ESX host that uses iSCSI.
According to NetApp best practice, which three actions accomplish this task? (Choose three.)

• 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.

Answer: BCE

NEW QUESTION 11


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.

Answer: C

NEW QUESTION 12

A customer is deploying a SAN cluster of A700 nodes and wants to ensure that the SAN cluster will maintain a quorum in the event of a rack level power failure. Which two statements are true in this scenario? (choose two.)

• A. Six nodes are required
• B. Four nodes are required
• C. Three racks are required
• D. Two racks are required

Answer: AC

Explanation:
The quorum rule states that to make changes to the configuration in our cluster, we need to have more than half of the nodes available. This prevents configuration conflicts if we lose connectivity between the nodes in our cluster.
So, if we have only 2 racks and 4 nodes we could never get more than half of the nodes available if one of those racks power fails.
We need 6 nodes separated on 3 racks, so we can have more than half of the nodes available if one of those racks power fails.

NEW QUESTION 13

• D. Gather the IQN from the host initiator software.
• E. Gather the NQN from the host system.

Answer: ABE
