The questions for NS0-520 were last updated On Feb. 25, 2024

Question #1

You are configuring a new Netapp ONTAP cluster and are connecting the nodes to Cisco MDS SAN switches. You connect one of the nodes to switch port fc1/11 and run the commands that are shown in the exhibit. The SAN LIFs are enabled but are not operationally online, and none of the SAN hosts can access their LUNs on the ONTAP cluster.

In this scenario, which configuration would cause this problem?

Reveal Solution Hide Solution
Correct Answer: D

in-order guarantee and interoperability mode are default configuration on a VSAN

NPV is the core switch where NPIV is going to be enabled.

The NPV core switch is defined as an upstream switch on which NPIV is enabled. The NPV core switch receives traffic that is passed to it from a downstream switch that has NPV enabled on it. A switch that is in NPV mode does not switch traffic; instead, it passes traffic to the upstream NPV core switch on which NPIV is enabled.

After NPIV is enabled on the core NPV switch, the port should automatically come up (unless there are other issues).

Question #2

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)

Reveal Solution Hide Solution
Correct Answer: C, D

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).

Question #3

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.

Correct Answer: D

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.

Question #4

You are designing a new 4-node AFF A400 SAN cluster with 20 ISCSI hosts. Each AFF A400 node will have four data LIFs. Each ISCSI host needs to access every LUN over two LIFs per node on every

SAN node.

In this scenario, which Netapp SAN feature enable this connectivity?

Reveal Solution Hide Solution
Correct Answer: A

SLM will choose 4 LIFs per node, being 8 LIF total (owner and HA partner), enabling portsets will help to limit the ports per node... that way we can stablish only 2 LIF per node.

Creating port sets and binding igroups to port sets

In addition to using Selective LUN Map (SLM), you can create a port set and bind the port set to an igroup to further limit which LIFs can be used by an initiator to access a LUN. If you do not bind a port set

to an igroup, then all of the initiators in the igroup can access mapped LUNs through all of the LIFs on the node owning the LUN and the owning node's HA partner.
