NetApp ns0-520 practice test
NetApp Certified Implementation Engineer - SAN, ONTAP Exam
Question 1
You have finished deploying a Netapp AFF All SAN Array Cluster and want to test the persistent ports
feature. In this scenario, how would you accomplish this task?
- A. Perform a takeover of a node
- B. Disconnect an FCP initiator port
- C. Disconnect an FCP target port
- D. Disable a SAN LIF
Answer:
A
Explanation:
If we don't have OnCommand Insight, then we should not pull out a cable as test because it won't be
detected properly.
Doing a planned takeover will meet the requirements asked.

Question 3
Your customer asks you how to connect a host for SAN access to the newly installed AFF A400
system. In this scenario, which two statements are correct? (choose two)
- A. Direct Connection to the nodes from the hosts with ISCSI is supported
- B. Direct Connection to the nodes from the hosts with ISCSI is not supported
- C. Direct Connection to the nodes from the hosts with FC is not supported
- D. Direct Connection to the nodes from the hosts with FC is supported
Answer:
A, C
Explanation:
ISCSI-Direct-attachment: In a direct-attached configuration, one or more hosts are directly connected
to the controllers.
You cannot directly attach FC or FC-NMVE SAN hosts to single nodes without using an FC switch.

Question 4
A database administrator needs to ensure that snapshot copies of database files across multiple
LUNs are taken at the same point in time. Which action achieves this outcome?
- A. Create each LUN within the same FlexVol volume
- B. Create each LUN on the same Fabric Pool aggregate
- C. Add each LUN volume to the same snapshot schedule
- D. Create each LUN within the same FlexGroup Volume 110/113 Questions & Answers PDF P-
Answer:
A
Explanation:
We can discard Flexgroup because it only works on NAS Protocols.
We can discard LUNs and Aggregates because snapshots are not taken at that level
Snapshots are taken at volume level

Question 5
Your customer asks you to configure a newly installed FAS8300 for an FC host connection.
Referring to the exhibit, which step accomplishes this task?
- A. Configure the ports 0e and 0f as a mode of CNA
- B. Configure the ports 0e and 0f as type of target
- C. Configure the ports 0e and 0f as status admin up
- D. Configure the ports 0e and 0f as status admin down
Answer:
B
Explanation:
To change the port type from initiator to target you need to take the port offline
The ports need to be on target mode to present LUNs to the hosts.

Question 6
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 109/113 Questions & Answers PDF P-
- 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

Question 7
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
Answer:
A
Explanation:
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

Question 8
You want to move a SAN LIF and preserve its configuration information and avoid rezoning the switch
fabric. In this scenario, which two steps must be performed to fulfill this goal? (Choose two)
- A. Move the SAN LIF to another node in a cluster on a different storage virtual machine (SVMs)
- B. Keep the SAN LIF online before it is moved
- C. Take the SAN LIF offline before it is moved
- D. Move the SAN LIF to another node in a cluster on existing storage virtual machine (SVMs)
Answer:
C, D
Explanation:
Moving SAN LIFs
If a node needs to be taken offline, you can move a SAN LIF to preserve its configuration information,
such as its WWPN, and avoid rezoning the switch fabric. Because a SAN LIF must be taken offline
before it is moved, host traffic must rely on host multipathing software to provide nondisruptive
access to the LUN. You can move SAN LIFs to any node in a cluster, but you cannot move the SAN LIFs
between storage virtual machines (SVMs).

should you perform before you test asymmetric namespace access (ANA)? (Choose two)
- A. Verify if the NVMe service has started
- B. Verify if the LUNs and namespaces are in the same volume.
- C. Verify if the version of Netapp ONTAP software is 9.5 or later
- D. Verify if there is only one LIF in the SVM 107/113 Questions & Answers PDF P-
Answer:

Question 10
A storage administrator needs to ensure that an ONTAP FC LUN is accessible for a remote data center.
The ISL ports are reporting errors. The trunkshow command output from a Brocade switch is shown
below.
- A. Set the ISL ports as FL_Ports
- B. Set the ISL ports as N_Ports
- C. Set the ISL ports as F_Ports
- D. Set the ISL ports as E_Ports
Answer:
D
Explanation:
On each switch fabric, you must configure the switch ports that connect the Inter-Switch Link (ISL).
These ISL ports are otherwise known as the E-ports.
