Up To Date NS0-520 Actual Test For NetApp Certified Implementation Engineer - SAN. ONTAP Certification

NEW QUESTION 1

You have an 8-node AFF A400 ONTAP 9.8 cluster that is serving FC and ISCSI LUNs. You have three SVMs for FC and one SVM for ISCSI, each for separate VMware VSphere clusters. The VMware
clusters are on separate, non-routable, networks. You are asked to set up SnapCenter software for backups of the Virtual machine datastores. What is the minimum management LIF count that is needed to
satisfy this requirement?

• A. four
• B. one
• C. eight
• D. two

Answer: A

Explanation:
You need to configure an SVM management LIF to link it with snapcenter... every SVM will need 1 management LIF minimun and we have 4 SVM

• D. 8

Answer: C

NEW QUESTION 3

• C. Add a converged network adapter (CNA)
• D. Enable MPIO by selecting the option in the MPIO properties administrative application

Answer: BD

Explanation:
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

NEW QUESTION 4

You use iSCSI to present a LUN to a newly installed Windows 2016 Server. You have created the volume and LUN on the NetApp cluster. When you perform a hardware rescan on the Windows host, you cannot see the newly presented storage.
What are three reasons for this problem? (Choose three.)

• A. The protocol has not been enabled on the NetApp cluster.
• B. You need to add the IQN of the Windows host to the newly created LUN.
• C. The IQN of the Windows host is not included in the igroup for the new LUN.
• D. The wrong igroup has been associated with the new LUN.
• E. The volume has not been enabled for iSCSI access.

Answer: ABD

NEW QUESTION 5

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«t igroup.

Answer: BD

NEW QUESTION 6


Referring to the exhibit, what happens when you change the type for port 1a from target to initiator?

• A. The port type for 1a changes to initiator, and you must reboot the controller for the changes to takeeffect.
• B. You receive an error message that you must take ports 1a and 1b offline before you can change the type.
• C. You receive an error message that you must take the port 1a offline before you can change the type.
• D. The port type for 1a and 1b changes to initiator, and you must reboot the controller for the changes to take effect.

Answer: A

NEW QUESTION 7

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

Answer: C

NEW QUESTION 8


Referring to the exhibit, you have SAN LUNs on an AFF A700s and are asked to test an SSD shelf stack failure.
What is the maximum allowed number of failed paths per controller to shelf stack before a storage failover occurs?

• A. 1
• B. 3
• C. 2
• D. 4

Answer: C

NEW QUESTION 9

You are configuring a VMware sphere host for FC access to a Netapp ONTAP cluster. In this scenario, which two tasks does Netapp recommend performing on the Vsphere host? (choose two)

• A. Set the queue depth on the host to 8
• B. Update the HBA driver
• C. Zone the host by using the host WWNNs
• D. Use the Netapp Virtual Storage Console to configure the host settings

Answer: BD

Explanation:
Zoning the host using WWNNs is not recommended. Netapp always recommends to use WWPN to zone correctly.
We can not stablish a queue depth value because we don't have the amount of ports and hosts to calculate the recommended queue depth
Installing VSC and updating the HBA driver are best practices recommended by Netapp

NEW QUESTION 10

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

Answer: B

Explanation:
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.

NEW QUESTION 11

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

Answer: C

Explanation:
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

NEW QUESTION 12

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

Answer: A

Explanation:
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

NEW QUESTION 13

An administrator is configuring a SAN-only cluster. The data room that houses four AFF A220 controllers is small and not able to house the DS224C shelves. The administrator proposes to rack the shelves in a separate room that is 40 meters away from the controllers.

• A. Use multimode passive optical cables.
• B. Use multimode active copper cables.
• C. Use multimode active optical cables.
• D. Use multimode passive copper cables.
